Solar-powered panels convert the sun's rays into electricity by using the photons of light from the sun. In most solar systems, solar panels are placed on the roof. An ideal site will have no shade on the panels, facing installation will usually provide the most potential for your system.Trees or other factors that cause shading during the day will cause significant decreases to power production. The importance of shading and efficiency cannot be overstated. In a solar panel, if even just one of its 36 cells is shaded, power production will be reduced by more than half.So that means the require lots of sunlight.
