About Difference between photovoltaic panels facing east and south
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.
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.
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.Panels turned away from the south generate less power – about 15% less when facing east or west, and around 30% less if facing north.
Panels turned away from the south generate less power – about 15% less when facing east or west, and around 30% less if facing north.
Homes that have solar panels facing directly east or west will produce around 20% less energy. The proper solar panel orientation for homes located north of the equator is facing true south.
Roof Pitch and Orientation: While solar panels facing directly east or west generate around 20% less electricity than south-facing systems, they still save you money.

6 FAQs about [Difference between photovoltaic panels facing east and south]
Should solar panels face east or west?
Homes that have solar panels facing directly east or west will produce around 20% less energy. The proper solar panel orientation for homes located north of the equator is facing true south. For homes located south of the equator, it will be the opposite—,facing true north.
Which direction should solar panels face?
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 another direction. South-facing panels have superior economics for the following reasons: They allow for better solar battery utilization.
Which direction should solar panels be placed?
In the northern hemisphere, the general rule for solar panel placement is, solar panels should face true south (and in the southern, true north). Usually this is the best direction because solar panels will receive direct light throughout the day. However there is a difference between magnetic south and true south that must be considered.
Do solar panels face south?
Solar Tip: If you’re not sure which direction your roof faces, you can look your address up on Google Maps. The grid shows which direction is true south and you can compare that to your rooftop’s direction on the satellite imagery. As mentioned above, solar panels will produce more energy when they face south in direct sunlight.
Why is south the Best Direction for solar panels?
Our understanding of why south is the best direction for solar panels in the United States starts with the equator. This is the imaginary line that separates the earth into two hemispheres: northern (where the US is located) and southern. It’s also the center of the range where the sun sits in the sky.
Are south-facing solar panels better than east-facing?
In general, solar panels that face either directly east or west produce about 20% less electricity than if they faced south. While you’ll still save money, you may have to install a few more panels to cover all of your home’s electricity usage with solar compared to a south-facing system.
