Slope Of Roof For Solar Panels

However the panels can be installed anywhere between 10 to 35 deg with negligible efficiency loss.

Slope of roof for solar panels.

So for this roof the optimum angle is 35 a bit over an 8 12 roof slope and at this angle the roof generates 1 265kwh m2 day. Away from a horizontal ridge on both sides to create the 36 in wide path. Most australian homes have a roof pitch of 20 to 30 which is considered optimum for maximizing solar power generation. A roof slope that angles between 15 40 degrees should suffice for most solar power systems.

However even if you lower the tilt of your roof all the way down to 5 production only decreases by about 10 percent. The orientation of the panels and the angle they are tilted will have a greater effect on annual energy production. Your solar panel installers can help determine if your roof slope is suitable for solar panel installation. Optimal electricity production occurs when solar panels face south at a tilt equal to 30.

The energy reduces as we move away from this optimum angle. For roofs where pv panels cover up to 33 of the total area in plan view essentially as seen from above the panels must be at least 18 in. Individual solar panels can also be adjusted to an optimal angle that maximizes their sun exposure.
