Calculate Angle Should A Solar Panel Be

First of all in the choice of the tilt angle for solar panels on a house roof we are bound to satisfy two basic needs.

Calculate angle should a solar panel be.

Both of these angles require latitude degrees. Here two simple methods for calculating approximate solar panel angle according to your latitude. The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer. For spring and fall multiply your latitude by 0 98 and subtract 2 3 degrees.

For the best results solar panels should be oriented towards the south. If your latitude is above 50 see other situationsbelow. For a latitude up to 25 take your latitude and multiply it by 0 87 for a latitude between 25 to 50 take your latitude multiply by 0 87 after that you will add 3 1 degrees for a latitude over 50 the most ideal angle will end up being approximately 45 degrees. If you are able to adjust the angle of your solar panels a few times per year here is the adjustment schedule we recommend.

Tilt the panels to your latitude minus 15. Well now that we know that the optimal direction is south we need to find the optimal tilt angle. For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49. For example if the location of the solar array is at 50 o latitude the optimal tilt angle is also 50 o.

Similarly you can calculate the angle for winter by adding 15. A general rule for optimal annual energy production is to set the solar panel tilt angle equal to the geographical latitude. This is because the sun is always in the southern half of the sky in the northern hemisphere. Tilt the panels to your latitude plus 15.

Orientation of the panels. Use one of these formulas to find the best angle from the horizontal at which the panel should be tilted. If you do plan to optimize solar collection in every season use the following calculations. Tilt the panels to your latitude.

If your latitude is below 25 use the latitude times 0 87. Essentially the closer a solar panel is located to the equator the more the panel should be pointing straight up. Tilt the panels to your latitude. The more exact way to count out the best tilt angle is done as follows.

If your latitude is between 25 and 50 use the latitude times 0 76 plus 3 1 degrees. Whatever your latitude is you can subtract 15 from it to calculate the angle for summer.
