Best Angle And Orientation For Solar Panels

Similarly you can calculate the angle for winter by adding 15.

Best angle and orientation for solar panels.

A general rule for optimal annual energy production is to set the solar panel tilt angle equal to the geographical latitude. 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. For example if the location of the solar array is at 50 o latitude the optimal tilt angle is also 50 o.

Both of these angles require latitude degrees. In the northern hemisphere the sun is due south at solar noon. There are two methods for calculating the tilt angle for solar panels. 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.

We then place panels on your roof in the best available places and measure the specific output of these panels based on their positions. It s actually possible to increase energy production. 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. For the best results solar panels should be oriented towards the south.

For los angeles a solar panel tilt of 19 degrees works the best. On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north. This is because the sun is always in the southern half of the sky in the northern hemisphere. And then for summer the tilt solar panel angle calculation is done and processed by multiplying the latitude range by 0 9.

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. 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. Whatever your latitude is you can subtract 15 from it to calculate the angle for summer.

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. Latitude x 0 9 29 degrees. For instance in the san francisco bay area the best solar panel tilt angle is between 22 23 degrees.
