Cleaning solar panels regularly with efficiency and keeping them dust-free after installing them on the roof, will make sure the system can work correctly and for a longer time. Consider incorporating regular check-ups and cleaning into your solar panel maintenance schedule after installing it on your roof. An annual solar system installation must be checked by a qualified technician to ensure the proper function of all components that are required to install the system on your roof and to protect the solar system's warranty. Keep records of maintenance and repairs of your solar panel after installing them on your roof. If you reside in a region that experiences a lot of snowfall on the roof, you may need to clear the snow from your roof and the solar panels situated on your roof during the winter. Ice and snow factors can accumulate on the solar systems, reducing their performance of solar light consumption. In rare cases, the weight of the ice and snow may cause damage to the solar panel placed on your roof. Solar panels are a long-term investment. You can install solar panels on your roof and secure reduced energy bills. This investment will last for many years. You can help ensure that the solar system technology can continue to generate solar power for many years and help you save money. This can be possible by following a few easy procedures to keep the solar panels clean and well-maintained. ## Can you walk on solar panels? Solar panels that you have installed on your roof, are designed to be durable and weather resistant. However, solar panels are not indestructible. Walking through the particular space of your roof where the solar panels are installed or walking straight on the panels can damage them, causing the solar panels to become less efficient or even the entire installation can stop working altogether. If you must walk in the space of your installed solar panels, be sure to do so carefully. When it comes to installing solar panels on roofs to get energy, maintain a safe distance of at least 6 inches between each system size. When it's time to transport the solar panels for installation on the roof, be careful not to walk on the edges of the solar panel since this can cause the solar panels to crack or break. Avoid stepping on the panel roof surface on rainy days especially when it's raining because footprints can reduce the panel's ability to absorb light and the [lifetime of the units](/guides/solar-power-systems/how-long-do-residential-solar-panels-last). Although it is not ideal if you must walk on solar panels after their installation on your roof, be cautious and take measures not to break them. ## Do solar panels damage your roof? Installing solar panels on your roof without any roof damage is critical. If you want to install solar panels on your roof and protect your roof from damage, then make sure you let a qualified professional handle the installation of your solar system on your roof to prevent any accidents and [roof damage](/guides/solar-power-systems/does-solar-damage-your-roof). The solar cells we install for energy generation will not damage your roof in any way; in fact, they may even help the roof from any storm damage and weather-related wear and tear. If your solar panel system on your roof is displaying any signs of leaking or malfunctions, don't hesitate to have a qualified technician take a look at the solar power system of your roof. Problems that are left will only grow worse over time. ## What disadvantages do solar panels have? Solar panels have a few disadvantages. Solar installation to get energy can cost you high, they require regular maintenance, and severe weather and heavy rain on the roof can damage the solar panels. Although there are some cons to using and setting solar panels on your roof to get energy for free, the many factors and benefits can affect your decision of whether solar panel installation on your roof is a decent option. It can save energy and control the power supply for many residences. It can also capable to generate energy for commercial businesses. The most important thing is that it's a clean renewable energy source that can generate solar energy for your utility at a minimum cost. Apart from saving money and energy consumption, a solar installation on your roof can help you use clean energy and reduce your carbon footprint. You can install solar panels on the roof and charge your inverter battery and electric car with the solar panels since the cost of charging them would be lower than your regular main energy source. It can also replace your home inverter to some extent to generate energy during a power cut or a blackout. Solar panels can also can reduce the cost of your electricity bills and save you money in the long run. ## Do solar panels work well in winter? Solar panels on the roof are most effective in producing renewable energy from sunlight when they soak up direct light and heat from the sun and generate energy without any cost. In the environment of winter, though, there are fewer hours of solar light, and the sun sits lower in the sky which is not suitable for creating energy. The above combination of light and heat can result in less direct sunlight hitting solar panels on your roof and can create difficulty in generating energy. Snow and ice can also reduce the amount of sunlight from the environment that reaches the solar panels to produce energy. Ice and snowfall on the roof can weigh down the panels and might cause them to fracture in extreme cases. Despite these challenges, an installed solar system on your roof can still [produce clean solar energy](/guides/solar-power-systems/do-solar-panels-make-house-hotter) from the sun in winter. They may not be as efficient in producing more energy as they are in summer, but they will still produce clean energy. ## How often should you wash solar panels? Solar panels installed on the roof to generate energy should be washed once every few months to clear stubborn grime, dust, bird droppings, and all other stuff. This can be done more or less often, depending on the location of the panels, the space of your roof, and the amount of dust and dirt they collect. Washing solar panels and making them dust free is not difficult, it doesn't take one hour from your busy schedule. Most homeowners use a hose or a pressure washer to clean solar panels and remove dirt and debris. Be sure to use gentle pressure so you don't damage the panels. If you live in an area with heavy pollution, you may need to wash your system more often to protect it from dust, dirt, and bird droppings. Also, if your panels are installed near trees or other sources of debris, you may need to clean them more frequently. ## What should I use to wash solar panels? Cleaning solar systems requires a delicate touch and efficiency. Strong chemicals can affect breaking down the material of the panels, leading to decreased output and function. A gentle soap and a good quality soft brush will clear all the dust and do the trick just fine. Add a minimal amount of soap to a bucket of water, then use a soft cloth or brush to scrub the panels. Make certain you rinse the soap off entirely when you are done. You can purchase solar panel cleaning products that are designed not to damage delicate surfaces. ## What is a true-up bill for solar? A true-up bill is a statement from the utility company that reconciles the actual amount of electricity that the homeowners have used with the amount of electricity that was credited to the homeowners from their solar panels for their energy usage. Solar panels generate electricity during the daytime. This electricity is sent to the grid, and the homeowners are given a credit for it. At the end of each billing cycle, the utility company will send a true-up bill to the homeowners. These energy bills show how much electricity they used, how much was credited to them and the net amount that the homeowners owed for the month. If you have a net credit on your true-up energy bill, this means that your installed solar panels are producing more electricity than you used and saving money for you. ## What is the difference between a grid-tied and off-grid solar system? A solar system is grid-tied if it is linked to the electricity grid. When your solar panels generate excess energy than you consume, you may sell surplus energy back to the utility company. An off-grid solar system technology is not linked to the power grid. This implies that you'll need to keep extra electricity in batteries for night or during a power outage usage. ## What is the difference between a solar lease and a solar power purchase agreement (PPA)? A solar lease is a contract with the solar industry in which the property owners agree to pay a fixed monthly fee to the solar energy-producing company for the use of solar panels after their installation on the property. The panels remain the property of the leasing solar company, and property owners will be required to pay for any repairs or maintenance. A solar PPA is a contract in which you agree to pay a set price to the service provider for the energy produced by your installed panels. This rate is almost always lower than what you would typically pay for consuming energy of utility-generated electricity. The solar panel company owns the physical property of panels and assumed responsibility for the performance of energy generation and maintenance of solar batteries and other factors over time.

How To Go Solar This Summer

To cover your daily energy consumption you need a 3kW to 4kW solar system. Summer is the best time to install solar panel. When considering a solar system, you should first ask yourself these questions. - Does your home has unobstructed access to sunlight for most or all day, all year round? - Do you have a large enough roof for the system? - Does your community allow solar panels? - Is the installation of solar panels is worth the savings? Your solar system needs to be properly set up, installed and maintained for optimal performance, which is best done by a professional, licensed solar contractor. Size matters! Find out how big the system is to meet your electricity needs. Then check the roof area required for your PV module system. It is important how the PV modules are oriented to collect the maximum amount of daylight and seasonal sunlight. For various reasons many people do not have access to solar panels due to the expensive starting price for both the solar panels and the installation. ## How much does it cost to go completely solar? In Australia, a household consumes an average of 12 to 16 kWh of electricity per day. So to cover your daily energy consumption in Australia you need a 3kW - 4kW solar system, as a 1kWh solar system produces 4kWh of energy. To live off the grid, you need: ### Reliable solar battery Critical if you plan to store and use solar energy at night. If you use most of your energy at night, you will need a larger storage system of 10 kWh, which can cost you up to $12,000 (with installation included). ### Large off-grid solar system If you turn off the mains completely then you need a larger system and a 5 kW system will cost you between $4,500 to $8,000 dollars. ## Reserve generator In total, off-grid will cost at least $ 25,000, even after government discounts. But it is a long-term investment worth considering. ## How to go solar without the set-up costs Here are four of the ways which will help you get solar energy without putting solar panels on your roof: ### Peer-to-peer solar sharing networks You can share electricity with people living near you from a host who has installed panels on the roof for a fee. ### Using solar adapters or converters The device uses a smart output adapter. It measures the electricity you take from your wall outlet, and upgrades it to solar power, by purchasing small fractions of a solar energy certificate from an authorised solar farm. ### Solar powered bicycle Solar bikes have batteries that charge in the sun. Once charged, that energy can be used to charge small electrical devices such as tablets, phones, etc. ### Solar network Governments have already begun installing their own solar power farming projects, which provide electricity to entire cities across the country. You just need to connect to the grid, just like a normal grid.

Does Solar Damage Your Roof?

Most solar panels have a special coating that helps them resist weathering, corrosion and roof damage. When installing solar panels on your house roof, you should know that the solar panels are actually designed to protect your roof from roof leaks. Most solar panels have a special coating that helps them resist weathering, corrosion, and roof damage of your house or property. The frame of the panel is usually made out of aluminium or stainless steel, which are both durable materials that don't lead to leaking. Solar panels do more than just add aesthetics to your home roof; the structural integrity of a solar system can also help in preventing excess heat and roof damage, and as an additional benefit, the solar panels on your roof allow your roof last longer by shielding it from the weather. Making holes on the roof surface is one of the procedures of panel installation. Installing solar panels often requires holes to be drilled into the roof surface, but you shouldn't get scared of these holes, as the specialists will drill the holes skillfully. Roof surfaces crafted with clay, slate, or terracotta tiles are specifically vulnerable to roof damage and leaks. If the panels are not cleaned regularly, they can trap dirt and debris on your roof, which can lead to premature wear and tear. However, roof damage and other problems can be easily avoided with proper installation and maintenance. ## Are solar panels hail-proof? Most solar panels are designed to withstand hail and are left unchanged after a hail storm, but there is no such thing as a hail-proof solar panel. So, if you're living in a location situated in hail storm-affected areas, then the best way to protect your solar installations is to make sure that your panels are properly installed on the roof and that you regularly inspect your solar system. ## How do I know if my roof is suitable for solar? There are a few things homeowners need to take into consideration before installing a solar system. One such thing is determining your roof structure and deciding whether your roof is in good condition for solar installation or not. If the majority of your roof structure is in shade and doesn't get enough sun exposure and heat to install panels, then solar installation for energy generation may not be the greatest option for you. Homeowners need to check the weight capacity of their roof, if the roof material is clay or slate then talk with the solar installers clearly before installing the panels on your roof. Having shingles on the roof surface is also considered to be not good to install a panel, as shingles have the possibility of further roof damage. Additionally, you don't want the location of the panels on the roof space to cover any vents or skylights and be [easy to maintain](/guides/solar-power-systems/do-solar-panels-need-maintenance). ## How do I clean my solar panels? To maintain their efficiency, you must clean your solar system on a regular basis. After solar installation, you should clean your solar panels on your roof at least once a year, and more often if the solar panel system is located in an area that is prone to dust or bird droppings. A soft brush or cloth and mild soap and water are sufficient for cleaning the solar panel. They are not to be used to clean your solar panels because dangerous chemicals or rough materials might damage them. ## Can solar panels withstand high winds? Even though solar panels installed on your roof are built to last in strong winds, the solar panel can be broken if not installed correctly. If your solar panels are not secured properly at the time of solar panel installation on the roof, the solar panel can become loose and blow away in strong winds. In addition, if the solar panel installation is not conducted properly by the solar installer, they can stress your roofing materials and damage your roof structure by causing leaks. Fortunately, you can avoid roof damage and other difficulties by ensuring proper solar panel installation on your roof and regular upkeep to [ensure they last](/guides/solar-power-systems/how-long-do-residential-solar-panels-last). ## Do you need planning permission to install solar panels? It is always best to check with your local planning department to be sure. In most cases, solar panel installation is considered “permitted development” for the property owners, which means that the property owners are allowed without the need for planning permission. However, there are some exceptions, so it is always best to check with your local planning department before your solar panel installation. ## Do solar panels cause roof leaks? Solar panels can cause roof leaks if the solar installers can't install solar panels properly on the roof to generate energy. If the panels are not secured properly, they can become loose and blow away in strong winds. In addition, if the solar panels are not properly installed on the roof, they can stress your roofing materials and cause leaks. However, these problems can be easily avoided with a proper installation process and maintenance. ## What side of the roof should solar panels be on in Australia? The best orientation for solar panel installation is determined by a variety of criteria, including the latitude of your site and the slope of your roof. In general, it's preferable to put solar panels on the side of the roof with the [most sun exposure and heat transfer](/guides/solar-power-systems/do-solar-panels-make-house-hotter), though this isn't always possible. If homeowners need to install panels to Australian standards, then they should get the right protection during storms. ## Can solar panels be installed on a flat roof? Solar panels need to be positioned at the right angle of the roof in order to maximise their efficiency, and this can be difficult to do with a flat roof. In addition, flat roofs are more prone to leaks, so you will need to make sure that your solar panels are installed properly on the roof in order to prevent any leaks. ## Can solar panels be too heavy for the roof? Solar panels are not designed too heavy for most roofs, but you will need to make sure that your roof can support the weight of the solar panels. In addition, if you have a flat roof, you will need to be extra careful to make sure that the panels are installed properly in order to prevent any leaks. ## How do I know if my roof is suitable for solar? Before you can install solar panels on the roof for energy usage, you must check that your roof gets enough sun. If it's mainly in the shade, then solar probably won't work for you. If you have a new roof, then check the material of your roof first, though it's good to have a new roof as it doesn't have shingles, as shingles on the roof surface are not suitable for solar panels on the roof. ## How do I know if my roof can support solar panels? The most straightforward method to establish if the structure of your roof can hold solar system and generate electricity is your solar system installer. They will review your roof and advise you whether it can work for the solar system. ## What type of roof is not suitable for solar panels? Not all roof types can have solar panels installed on them to get energy. These include roofs that is mostly in the shade and can't generate energy from the sun rays, roofs that can't support the weight of the panels ( the weight of a solar panel is only 1\\4 the weight of an average male person) and some flat roofs. If you're not sure that your roof is suitable for solar electricity generating, you can always consult with a professional or the installer of your system before installing it on your roof. ## Will solar panels get damaged in a hurricane? Although solar panels are engineered to be durable in heavy winds,hurricane-force conditions can damage them. If your solar panels placed on the roof are damaged in a hurricane, you will need to have them repaired or replaced. ## What is the lifespan of solar panels? Solar panels that can generate energy are designed to last for many years, but their exact lifespan will depend on a number of factors, such as the type of installed panels and the amount of sunlight they are exposed to. In general, they may last for 20-25 years. ## How much do solar panels cost? Solar panels can range in price from $2,000 to $10,000, depending on the size and type of panel that the installation companies provide you. ## Are there different types of solar panels? The three most common solar panels are available in the solar system industry that can generate energy, photovoltaic, thermal, and concentrated. Photovoltaic converts sunlight into own electricity to generate energy, while thermal uses sunlight to produce heat. Concentrated solar power utilises mirrors that reflect and concentrate the sun's light onto a small area. [Energy.gov.au](https://www.energy.gov.au/households/solar-pv-and-batteries) has some great information on solar panels and batteries.

Do Solar Panels Make The House Hotter?

Solar panels absorb energy, and this solar energy output is renewable energy that also help to regulate the temperature inside your home. By reflecting some of the sun's energy back into the atmosphere from the earth's surface, it helps regulate the temperature in your house throughout the seasons. Solar panels absorb energy, and this solar energy output is renewable energy that also help to regulate the temperature inside your home by providing shade and insulation through power generation. ## Do solar panels cause roof leaks? No, solar panels don't cause roof leaks. They serve as a protective layer between your roof and the sun's heat. They also prevent excessive heating of your roof during summer and provide extra warmth in cold climates below freezing weather. This helps to prevent ice dams from forming on your roof in cold weather which can cause leaks [and other damage](/guides/solar-power-systems/does-solar-damage-your-roof). ## Do solar panels increase the value of my home?

Solar panels are just as effective in winter as in summer, climate change doesn't affect on its efficiency. ## Can too much sun damage solar panels? No, solar panels are designed to withstand high levels of sunlight and extreme weather conditions. However, you should clean your panels regularly to ensure that the sun's rays can be able to reach the solar surface and allow them to function properly. ## What happens if my power goes out? Even if the power goes out or in very less power as in low voltage situation, solar panels continue to produce energy. You can use this electricity to either light up your home or charge batteries. Solar panels work with their maximum efficiency when the energy production is maximum in extreme heat. ## What is the difference between solar PV and solar thermal? Solar PV system refers to the process of converting sunlight into electricity. Solar thermal refers to the process of using sunlight to generate heat. Solar PV modules are more commonly used in residential applications, while solar thermal is more commonly used in commercial and industrial applications by solar companies and solar manufacturers. ## What happens if solar panels freeze? The solar panel system is hardy and very strong. If they should freeze, however, it's crucial to thaw them out gradually rather than all at once to avoid harm. They can withstand extreme weather conditions, colder temperatures, heavy snow and higher temperatures with little effect on solar output. Extreme cold weather doesn't affect solar panels. Their dark and reflective glasses accelerate snow melt, as the snow melts it slides off without hampering the performance of the panels. You will need to [maintain them regularly](/guides/solar-power-systems/do-solar-panels-need-maintenance). ## At what temperature do solar panels stop working? Solar panels work even in very cold temperatures. However, they may not be as efficient in cold weather as they would be in warm weather as solar energy is not up to mark in cold weather states. Solar energy generation depends upon the solar energy absorbed. Solar battery storage and electricity generated also depends on these factors. ## How many Kg of weight do solar panels add to a roof? Solar panels range in weight from 18 to 30 kg per square meter. The solar panel performance and weight will vary depending on the sort and size of panel you choose. ## What do I clean solar panels with? You can clean solar panels with water and mild soap. ## Do solar panels fail in high heat? Solar panel can easily resist high temperature. In fact, solar panels work better in hotter climates, as it gets more solar power to produce energy. However, if a solar panel gets too hot, it can reduce its power output. Solar panels are made of materials that can withstand high temperatures, such as tempered glass. The cells in solar panels are also designed to maintain its power generation when the temperature rises. In fact, most solar panels have a built-in temperature control system that keeps the cells at a safe temperature. Installing solar panels is beneficial because they are designed to be durable and reliable, even in extreme conditions, like too much heat. Solar panels produce electricity through this renewable energy having efficient power output. ## What is thermal comfort in my home? Thermal comfort is determined by air temperature, humidity, radiant temperature (temperature of surfaces around you) and clothing. All these factors play a role in how comfortable you feel and how your body regulates its own temperature. The thermal comfort in your home depends on a variety of factors, such as the climate, the type of heating and cooling system you have, the insulation and construction of your home, and your personal preferences. There are several ways to improve the thermal comfort in your home, such as adding insulation, using energy-efficient windows, and adjusting the thermostat. You can also take steps to reduce drafts and improve air circulation.

Solar panel efficiency can help to offset the cost of heating your home in several ways. First, they absorb enough energy in daylight hours. Second, solar power can be used to generate electricity, which can be used to operate an electric heater or other appliance lowering your electricity bills. Third, solar panels have solar cells that use direct sunlight to heat water, which can then be used for space heating or domestic hot water. In general, solar panels are most effective at cutting the cost of heating when they are used in combination with other energy-saving measures, such as insulation and energy-efficient windows. ## Do solar panels lose efficiency when hot? Solar panels are designed to operate in a wide range of temperatures, from -40 degree Celsius to +85 degree Celsius. They will still produce electricity in hot weather even if there is a cloud cover, but their efficiency may be reduced due to climate change. Solar panels have a temperature coefficient around -0.3% to -0.5%. All solar cells have a temperature coefficient. Solar panels are made of roofing material that can diffuse light and absorb more power from the sun, such as tempered glass by solar experts. The solar cells in solar panels are also designed to withstand high temperatures. In fact, most solar panels have a built-in temperature control system that keeps the cells at a safe temperature. Solar panels are designed to be durable and reliable by absorbing maximum solar power by direct light. ## How can solar panels help to heat my pool? Solar panels function by your pool in two ways: by providing free heat from the sun, and by generating electricity that can be used to power a pool heater. Solar panels are most effective at heating pools when it is used in combination with other energy-saving measures, such as insulation and an automatic pool cover.

How Long Do Residential Solar Panels Last?

Most residential solar panels on the roof of buildings come with a warranty of 20 to 25 years but may last as long as 40 years. You can expect your panels to keep generating electricity for two decades or more after the warranty has expired. Moreover, these panels degrade very slowly over time, so even after 40 years, they should still be able to produce around 80 per cent of the electricity they did when they were new. They are tested to withstand extreme weather conditions like hail. Solar panel hail damage can cause a decrease in solar production, but you can always use solar panel protective covers to save them. In the covered solar panel hail damage is not a problem. Hail damage affects most without the covers. ## Do solar panels need to be cleaned? While it is true that solar panels need to be kept clean in order to function optimally, most modern panels are self-cleaning. This means that they have a special coating that causes rain or snow to slide right off, taking any dust, dirt or debris with it. In most cases, you probably won't need to do any cleaning yourself, except maybe an occasional hose-down or [basic maintenance](/guides/solar-power-systems/do-solar-panels-need-maintenance) if your panels get particularly dirty when come in contact bird droppings. You can use a good quality soft brush to clean solar panels to enhance efficiency. ## How much do solar panels cost? The average cost of a single panel is now around $200, and a typical 4 kilowatt (kW) system - which is enough to solar power a small home - retails for around $8000. However, the cost of a panel system will vary depending on the size of the system, the type of panels used, and other factors for homeowners, like hail. ## Will solar panels increase the cost of home insurance? Solar panels should not increase the cost of home insurance. Insurance providers may even offer a discount, as they can reduce the risk of fire (since panels are free from electrical wires) and lower your energy bills. To be on the safe side, it's best to contact your insurance company. ## Does hail damage solar panels? Hailstorm can damage solar panels, but it is not a common occurrence. Solar panels are built to withstand hailstones and other [potential damage](/guides/solar-power-systems/does-solar-damage-your-roof). If you use appropriate safety equipment, the installed solar modules can function perfectly in hail. ## What happens to solar panels when they break? Most manufacturers offer a free warranty on their products or insurance, so if your solar panel breaks within the warranty period, the insurance company will likely cover the full cost of repair or replacement. Storms can damage the solar panels. ## How do solar panels work? Solar panels convert sunlight into electricity. The solar panel absorbs energy, which is then converted into electricity by the photovoltaic effect. ## What are solar panels made of? Solar panels are made of silicon, which is a material that enables an electric charge. When exposed to light, silicon generates an electric field that produces electricity. Solar panels also include metals such as aluminium and copper to aid in the transmission of energy. ## Do solar panels help in the winter? Solar panels can still generate electricity in the winter, but they are not as efficient in cold weather as they are in warm weather. This is because solar panels rely on sunlight to generate electricity, and there is less light available in the winter months. This is the reason it is fixed on the roof rather than the ground. ## How long do solar panels take to pay for themselves? This depends on a number of factors, including the cost of the solar panel system, the electricity rates in your area, and how much solar energy your panels receive. In general, it may take between 7 and 10 years for a solar panel system to pay for itself. ## Does heat affect solar panels? Yes, [heat can affect solar panels](/guides/solar-power-systems/do-solar-panels-make-house-hotter). Solar panels are designed to withstand high temperatures, but if they get too hot, they can become less efficient at converting solar energy into electricity. A solar inverter regulates the passing of voltage. An inverter battery is charged by the metal and chemical installed in the battery preventing the excess heat flow. ## What is the best way to clean solar panels? Cleaning your solar panel is as easy as using some water and a soft cloth - no need for any harsh chemicals or abrasive materials which could potentially damage the panel surface in contact with stubborn grime and dirt. However, the efficient solar panels require regular cleaning to enhance the panel's performance. You can use the garden hose on low pressure to clean them. ## What can damage solar panels? There are a few things that can damage a solar panel including hail storms, snow storms strong dust winds, rain and debris. However, most efficient panels are built to withstand all sorts of weather conditions, and they are very durable. ## How often do solar panels need to be cleaned? Solar panels can go for 6 months or more without being cleaned. If your solar panel is covered in snow or ice, you will need to remove the debris before it can start generating electricity again. ## Can hail damage solar panels? Hail damaged solar panels are not efficient, but most efficient panels with high power are built to withstand all sorts of weather conditions, including hail. Solar panel hail damage is not a regular occurrence, but it is better to buy one that can withstand hail storms. ## How are solar panels made? Most solar panels are made of silicon. When silicon is exposed to sun energy from solar system, it produces an electric field that generates electricity. The panels also contain metals such as aluminum and copper, which help to conduct the electricity generated.

Frequently Asked Questions

What is a grid connect solar power system?

Grid connect systems supply solar electricity through an inverter directly to the household. You can save money on your power bill.

What can affect the amount of solar energy received?

The strength of the solar energy (radiation) available depends on the time of year, day, and the latitude of the generation point.

Does roof orientation really matter?

Most certainly. For example, a system with solar panels facing in a southerly direction will generate far less than one with a northerly aspect.

What is a feed in tariff?

A feed in tariff is whereby a grid connect system owner is paid for the electricity their system generates by a utility or government agency.

Can I insure my grid connect system?

Most insurers will allow you to include the system under your home and contents insurance, but check with your insurance company first.

If my energy requirements increase, can I upgrade the system?

Yes. Additional solar panels can be added at any time to increase generating capability, but you might have to upgrade to a larger inverter.

What happens on cloudy days?

In a grid connect system, as you are still tied to the mains power supply, any deficit will come from the mains grid.
