Whether you are installing a solar panel on a flat roof or a pitched roof the output of the solar pv system would be increased by optimizing the tilt angle.
General tilt angle solar panels.
Tilt the panels to your latitude plus 15.
Tilt the panels to your latitude.
Whatever your latitude is you can subtract 15 from it to calculate the angle for summer.
The tilt is 0 if solar panel parallel to horizon to design the tilt is 90 if the solar panel is vertical to design.
The solar panel angle can affect the amount of solar electricity you generate and is based on two factors.
The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer.
Similarly you can calculate the angle for winter by adding 15.
Both of these angles require latitude degrees.
Solar panel angle is another way of describing the vertical tilt of your pv system.
If it s standing upright perpendicular to the ground it is at a 90 angle.
For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49.
The summer optimum tilt angle on the other hand will be 34 15 19.
When a solar system is level with the ground it has no tilt.
Latitude and the season.
The decision of azimuth.
Tilt the panels to your latitude.
A flat roof has a 0 degree tilt and a vertical wall mount has a 90 degree tilt angle.
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.
