Optimal installation direction of photovoltaic panels

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.

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 certain times, usually in the form of peak rates.

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: many.

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.For maximum output, the sweet spot for solar panels in the continental U.S. is facing roughly south and tilted between 15 and 40 degrees, according to the Department of Energy.

Going by the larger say, the best roof direction for solar panels is roughly south-facing, and this is known because the sun is mostly seen in the southern sky or the northern hemisphere.

For most homeowners, the ideal angle for a solar panel installation is close to or equal to the latitude of your home. This angle is typically between 30 degrees and 45 degrees.

Key takeawaysIn the U.S., solar panels perform the best – that is, generate the most power – when they face south.South-facing panels are also best if you use net metering or use solar batteries for energy storage.Panels turned away from the south generate less power – about 15% less when facing east or west, and around 30% less if facing north.

Optimal Directions for Solar Panel InstallationDirection in the Northern Hemisphere In the Northern Hemisphere, the optimal direction for solar panels is typically south-facing. Direction in the Southern Hemisphere For homes in the Southern Hemisphere, north-facing panels are ideal for the same reason ensuring maximum exposure to sunlight.Exceptions and Special Cases .
