Ideally you want your solar system to be on the area of your roof that faces south specifically southwest.
Optimal angle for solar panels pennsylvania.
What s the best angle for solar panels.
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.
Use one of these formulas to find the best angle from the horizontal at which the panel should be tilted.
The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer.
If your latitude is between 25 and 50 use the latitude times 0 76 plus 3 1 degrees.
The summer optimum tilt angle on the other hand will be 34 15 19.
That s because you ll get way more sunlight hitting the roof thereby converting into way more energy.
True south or the geographic south will yield the best results overall.
This is because the sun is always in the southern half of the sky in the northern hemisphere.
This solar angle calculator tells you the optimum angle to get the best out of your system.
For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49.
If your latitude is below 25 use the latitude times 0 87.
If you live in the southern hemisphere face them north.
Regardless of the exact cost of installation there are many affordable financing options for solar panel systems.
There are two methods for calculating the tilt angle for solar panels.
Similarly you can calculate the angle for winter by adding 15.
Optimal azimuth angle for solar panels for best results your solar panels should face toward the equator.
If you live in the northern hemisphere face them south.
Subtract 15 degrees from the latitude at your location during summer and add 15 degrees to your latitude during winter.
A solar payback period is the amount of time it takes for property owners who install solar panels to recover their initial investment through electricity savings.
To get the best out of your photovoltaic panels you need to angle them towards the sun.
In pennsylvania the average solar payback period is 10 66 years.
On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north.
Whatever your latitude is you can subtract 15 from it to calculate the angle for summer.
The optimum angle varies throughout the year depending on the seasons and your location and this calculator shows the difference in sun.
There s a simple rule of thumb for calculating the best tilt angle for fixed mount solar panels.
Orientation of the panels.
Both of these angles require latitude degrees.
