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 another direction. South-facing panels have. . 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. . 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. [pdf]
With panels on both east and west-facing roofs, you lessen the risk of shading significantly hindering your overall solar energy production. Additionally, some solar panel systems allow for individual panel monitoring and optimization, further enhancing the efficiency of an east-west setup.
Naturally, solar panels in the UK will work best when facing south, as it means they’re facing the sun. But if your roof doesn't allow for a southern exposure, east-west orientations can also work. Panels facing east will make more electricity in the morning, while those facing the west will generate more power in the afternoon and evening.
In the UK, solar panels should ideally face south in order to capture the most daylight throughout the day. It's best to avoid installing solar panels that face north, since there's never much daylight from that direction in the northern hemisphere. Panels can still perform well facing east or west.
East-west-facing roofs can offer unique advantages in the UK, where the sun’s path varies considerably throughout the year. With panels facing both directions, your solar system can capture sunlight at different times of the day.
As PV arrays begin orienting away from the south, they immediately become less efficient. In fact, west facing solar panels produce an average of 15% less electricity 2. However, those that pay for electricity via Time-of-Use (TOU) pricing plans can benefit from the change in direction.
But here in the UK, which gets less than half the annual sunshine of South Africa (1,387 hours versus SA’s 3,103), you need to put in a little more planning, and position your solar panels to capture maximum sunlight. The best direction for solar panels is the same wherever you are in the UK: facing south, and pitched at 40 degrees.
