A general rule for optimal annual energy production is to set the solar panel tilt angle equal to the geographical latitude.
Calculate angle should a solar panel be.
Similarly you can calculate the angle for winter by adding 15.
Tilt the panels to your latitude.
For spring and fall multiply your latitude by 0 98 and subtract 2 3 degrees.
This is because the sun is always in the southern half of the sky in the northern hemisphere.
Orientation of the panels.
Well now that we know that the optimal direction is south we need to find the optimal tilt angle.
Essentially the closer a solar panel is located to the equator the more the panel should be pointing straight up.
For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49.
Use one of these formulas to find the best angle from the horizontal at which the panel should be tilted.
For the best results solar panels should be oriented towards the south.
If your latitude is above 50 see other situationsbelow.
If your latitude is below 25 use the latitude times 0 87.
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.
The need for energy production and the need for an aesthetically pleasing and long lasting final result the roof of a house already has its own inclination and slope so a.
Tilt the panels to your latitude.
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.
If your latitude is between 25 and 50 use the latitude times 0 76 plus 3 1 degrees.
The more exact way to count out the best tilt angle is done as follows.
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.
Both of these angles require latitude degrees.
If you do plan to optimize solar collection in every season use the following calculations.
Tilt the panels to your latitude plus 15.
Whatever your latitude is you can subtract 15 from it to calculate the angle for summer.
Tilt the panels to your latitude minus 15.
There are two methods for calculating the tilt angle for solar panels.
