Best Angle And Orientation For Solar Panels

We then place panels on your roof in the best available places and measure the specific output of these panels based on their positions.

Best angle and orientation for solar panels.

The answers you end up with are the best angles for each particular season. Then you have to subtract 23 5 degrees the final solar panel angle will appear to be 34 0 9 23 5 7 1 degrees. While the angle of your solar panels is important a more important factor in your energy production is going to be the direction your panels face. Orientation of the panels.

These angles will give you the best overall output over the course of the year if you re going for a fixed installation. It s actually possible to increase energy production. On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north. For the best results solar panels should be oriented towards the south.

There are two methods for calculating the tilt angle for solar panels. Once you have figured this out you can use one of the formulas below to calculate the best angle for your solar panels for each season. This gives us an accurate output from which we calculate the cost and savings you will get based on your local solar prices and the amount you pay your utility company for electricity. Whatever your latitude is you can subtract 15 from it to calculate the angle for summer.

Both of these angles require latitude degrees. For los angeles a solar panel tilt of 19 degrees works the best. For example if the location of the solar array is at 50 o latitude the optimal tilt angle is also 50 o. In the northern hemisphere the sun is due south at solar noon.

Latitude x 0 9 29 degrees. Therefore to get the very best out of your photovoltaic panels you would typically face them due south at the optimum angle so that the panel is receiving as much sunlight as possible at this time. Latitude 2 5 degrees. For instance in the san francisco bay area the best solar panel tilt angle is between 22 23 degrees.

Since solar panels are more productive when the sun s rays are perpendicular to their surfaces the certainly best orientation is the one directly true south azimuth angle 180. This is because the sun is always in the southern half of the sky in the northern hemisphere. Latitude x 0 9 23 5 degrees. Essentially the closer a solar panel is located to the equator the more the panel should be pointing straight up.
