A good angle ensures that panels are exposed to the sun from sun-up to sun-down, no matter the weather.
Roof Pitch – 45 degrees is the optimum angle to catch the most light as the sun moves through the sky throughout the day.Factors that affect energy production include location, the roof pitch, shading, and the installation size – our solar rate calculator takes all of these details into account. So, while a 3.5 Kw solar array will likely produce 3,000 KwH per year (about 2/3rds of your average electric usage) in prime conditions in the UK, you will generate less energy if your roof is shaded. This production depends entirely on the sun, average exposure to the sun, and sometimes, the quality of the sunlight. It uses this data, along with your energy bill and the current Feed in Tariff rate to calculate your likely savings.Įnergy Production – Solar panels produce energy which is measured in KwH or Kilowatt hours. Our solar rate calculator determines the likely energy output of your PV array based on your home, location, and roof pitch as well as the size of the array.
