Optimal electricity production occurs when solar panels face south at a tilt equal to 30.
Opyimal slope solar panel.
At 30 the energy drops to 1 260kwh m2 year a reduction of just 0 4.
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.
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.
The table below features a solar panel angle by zip code for at least one city from every state.
To get the most from solar panels you need to point them in the direction that captures the most sun.
The summer optimum tilt angle on the other hand will be 34 15 19.
Optimal azimuth angle for solar panels for best results your solar panels should face toward the equator.
However even if you lower the tilt of your roof all the way down to 5 production only decreases by about 10 percent.
Many roofs are going to have slopes between 30 and 40 degrees which means that solar panels can lie flush against the roof and produce enough electricity for attractive returns.
What angle for solar panels should be chosen to maximize the production all year long.
Optimum tilt of solar panels.
For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49.
So for this roof the optimum angle is 35 a bit over an 8 12 roof slope and at this angle the roof generates 1 265kwh m2 day.
In this case for the solar panels to get their best performance a steep angle of 60 is best.
For both reasons for a fixed tilt on a pure geographic south slope solar panel the optimum angle is the latitude plus correction toward.
The energy reduces as we move away from this optimum angle.
During the spring the best angle is 45 and during the summer when the sun is high in the sky it s best to have a low tilt at 20.
If you live in the southern hemisphere face them north.
This page is designed to help you find the best placement for your solar panels in your situation.
Your life would be much easier if you could just find out what angle is the optimal solar panel angle in your city or county.
There is even a stronger factor the length of the day.
Well now that we know that the optimal direction is south we need to find the optimal tilt angle.
The angle of your roof actually has less impact on solar panel performance than the direction your solar energy system faces.
If you live in the northern hemisphere face them south.
The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer.
