solar panel efficiency, definition of

Solar Panel Efficiency is a percentage measure of how Solar Energy from the Sun hitting a solar panel is ideally converted into useful electrical power. This is often given assuming perfect conditions; i.e. no shade, maximum sun and cool. In practice the actual rate of conversion can be somewhat different due to:

• Shading - even partial shading can have a dramatic effect on the energy produced.
• Heat - the hotter a solar panel becomes the less efficient it is at converting solar energy into electrical energy.
• Sun Strength - akin to shading, but if the Sun is behind clouds or low in the sky you will get dramatically less power.
  

• Solar Panels for your home, with the reduced feed-in tariff, are they a sound investment?
  We take a more detailed look at solar panels and help you work out if investing your money in solar is the right thing to do for you and the environment.
