Use our complete solar panel calculator to help you make an informed and data-based decision. Using the latest solar intensity data for your area, our tool can model the output of your system with 96% accuracy, helping you to understand just how beneficial solar panels could be for you and your energy bills.
Our solar energy calculator answers this with precision. By taking into account factors such as your location, roof orientation, and solar panel efficiency, our tool accurately calculates your annual energy output from solar panels. But it doesn't stop there.
To determine the cost, you can use a solar panel cost calculator or consult with a solar panel installation company. The payback period represents the time it takes for a solar panel system to generate enough energy savings to offset the initial investment.
Solar panel efficiency refers to the amount of sunlight a solar panel can convert into usable electricity. It is calculated by dividing the amount of electricity produced by the solar panel by the amount of sunlight that strikes the panel. The efficiency formula is as follows: Efficiency (%) = [ (Pmax ÷ Area) ÷ 1000] × 100% Where:
After installing solar panels, there are two main kinds of benefits: financial benefits and practical benefits. Simply put, going solar replaces the ever-rising cost of grid electricity with a flat monthly payment on your solar equipment.

You can get paid to export electricity you generate but don't use through the smart export guarantee (SEG). An average home could earn up to £320/year.
