Flat rooftop solar panels array horizontal.

In the past panel manufacturers would not offer warranties on panels installed at an angle lower than 2 degrees but these days most of the top manufacturers will give warranties even if their panels are installed at 0 degrees completely flat. For optimum performance a solar panel should be at a 30 degree angle and face south or southwest. The size of solar panels makes them well suited to be installed vertically on most roofs. For flat roofs this angle can be achieved through brackets that are added onto the roof.

Solar panels will receive optimal exposure when mounted on a rooftop compared to a wall. Flat roofs that are truly horizontal can have a ballast or attached system put in place to create a pitch of at least 10 degrees. If your rooftop is flat you can use tilt legs to face panels so that they are more perpendicular to the sun. I t is easier to have a continuous row of solar panels if they are installed vertically.
