FAQs
How do solar panels work?
Inside each panel are many cells made from silicon, a material found in sand. Silicon can absorb light and convert it into electrical energy. When sunlight hits the solar panel, the energy from the light knocks electrons loose from the silicon. These free electrons are then channeled in a specific direction to create a flow of electric current. This process is known as the photovoltaic effect. For more information, see our full fuide on how solar panels work.
Are solar panels worth it?
Solar panels can be a great investment! They can significantly reduce electricity bills over time, and typically pay for themselves in 5-15 years. The initial cost of buying and installing solar panels can be high, but government incentives, tax breaks, and decreasing equipment costs can help offset these expenses. For more information, see our full guide on whether solar panels are worth it.
How much do solar panels cost?
The average cost of solar panels is around £7000. The price depends on how many panels you need, the installer you choose, and whether you’re having a battery installed too. For more information, visit our solar panels page.
How many solar panels do I need?
To figure out how many solar panels you need, start by checking how much energy you use each month, which you can find on your electricity bill. Then, think about how sunny it is where you live, because more sun means you’ll need fewer panels. Also, look at the solar panels themselves; some are more efficient and can make more electricity, meaning you might not need as many. For more information, see our full guide on how many solar panels you might need.
How are solar panels installed?
Installers attach a mounting system to your roof to hold the panels in place. The angle and orientation are carefully chosen to maximise the amount of sunlight your panels get. The panels are then attached to the mounting system. After the panels are in place, electrical wiring is connected, linking the panels to an inverter that converts the solar power from DC to AC electricity usable in your home.
How long do solar panels last?
Solar panels last 25 years on average.
