On average, you can expect around 850 to 1,100 kilowatt-hours (kWh) of solar energy per square meter (approximately 10.764 square feet) annually. Panel Efficiency: Solar panel efficiency determines how well the panel converts sunlight into electricity. The efficiency of commercially available solar panels is around 15% to 24.5%.
Solar panel efficiency is measured under standard test conditions (STC) based on a cell temperature of 25 ° C, solar irradiance of 1000W/m2 and Air Mass of 1.5. A solar panel's efficiency (%) is calculated by dividing the module power rating (W), or Pmax, by the total panel area in square meters at an irradiance level of 1000W/m2 (STC).
The article discusses calculating the square footage needed for solar panels before purchasing a rooftop solar power system. It explains that to determine the total square footage required, you multiply the number of solar panels by 17.55 square feet, the average size of residential solar panels.
Solar Irradiance: The UK receives less sunlight compared to sunnier regions, which affects the solar panel's output. On average, you can expect around 850 to 1,100 kilowatt-hours (kWh) of solar energy per square meter (approximately 10.764 square feet) annually.
The size of a solar panel does affect efficiency. In other words, the efficiency of a solar panel depends on its power output. A solar panel rated at 300W with a surface area of 1 square meter would have an efficiency rating of 30% ([0.3kW/1 square meters] × 100 = 30%).
