The rooftop program focuses on a model called distributed generation. This entails generating the power closest to areas where it is consumed. When ground mount solar farms go above a certain size there is often an issue with the transmission, especially in rural areas. A significant amount of electricity is unnecessarily lost during transmission over long distances… distributed generation minimizes that lost energy while simultaneously minimizing other grid connection and transmission issues.




 One of the biggest culprits on the decreasing efficiency of a solar panel is the gradual buildup of dirt over the surface. Basically, the dirt acts like a cover, preventing the surface from absorbing the light being directed to it. To prevent this, take a look at the panels and have them cleaned from time to time especially if the panels are installed flat on the roof. Debris like leaves from trees can cover the surface so have someone sweep them or spray them with a garden hose.

Other yucky stuff like bugs and bird droppings can stick to the solar array´s surface. In such cases, it is almost a must to use a damp cloth to wipe the area clean. To prevent damages, it would be a good idea to clean the panels on a cloudy day, early morning or an hour before they get too hot.
