Here is a summary of the best solar panel direction for every use case. Explanations are provided below. .
South is the best direction for solar panels to face overall. In nearly all situations, you will see the greatest utility bill savings and quickest payback period if your panels point south instead of. .
In the U.S., orienting solar panels true south (azimuth of 180 degrees solar noon) will result in maximum output. Face them any other direction, and you can expect to see a fall in solar panel output. Solar panels see a drop in solar power production when you. .
Orienting your solar panels between south and southwest is best if your utility uses Time of Use (TOU) billing. Where TOU billingis in place, utilities charge higher rates for electricity at. .
Barring a couple of exceptions outlined above, your rooftop solar energy system should ideally be facing south for maximum efficiency. Of course, this isn’t always possible:. [pdf]
