There s a simple rule of thumb for calculating the best tilt angle for fixed mount solar panels.
Best angle for solar panels latitude.
Movable and adjustable solar panels.
If you would like to get the absolute best performance from your solar panels you should put them up on movable scaffolding on the yard or on special movable panel holders or frames on your roof.
The same latitude of 35 would have a tilt angle of 59 6 for winter and 7 1 for summer.
Tilt the panels to your latitude.
Tilt the panels to your latitude minus 15.
On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north.
In this method the optimum tilt angle for solar panels during winter is calculated by multiplying the latitude by 0 9 and then adding 29.
How can you determine the optimum angle for solar panels for your state.
This is about 10 more or less from the readings obtained using the first method.
Tilt the panels to your latitude plus 15.
If your solar panels will have a fixed tilt angle and you want to get the most energy over the whole year then this section is for you.
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.
Why is the perfect solar panel angle simply your latitude.
Are solar trackers helpful.
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.
Find the best angle for optimizing solar collection during winter when solar energy is most scarce by multiplying your latitude by 0 89 and then adding 24 degrees.
The violet line is the solar energy per day if the panel is fixed at the winter angle discussed below these figures are calculated for 40 latitude.
This way you could adjust the tilt angle and direction of the solar panels to an optimal level.
Solar panels tilted at an angle equal to the latitude will face exactly midway between the sun s highest point in the sky in summer and its lowest point in winter.
Because your latitude is the same as the angle of the sun in the sky halfway between midwinter and midsummer.
In the above case example of a latitude of 34 the tilt angle will be 34 0 9 29 59 6.
It does not matter whether you have the best angle for solar panels.
Subtract 15 degrees from the latitude at your location during summer and add 15 degrees to your latitude during winter.
