The answers you end up with are the best angles for each particular season.
Best angle for solar panel in michigan.
But the best roof angle for solar panels has less of an impact on all of this productivity than the direction orientation in which your solar energy system faces.
For the best results solar panels should be oriented towards the south.
For a precise method use the second formula on this page to calculate tilt angle.
The result for chicago is 90 42 23 25.
On average the state of michigan receives 4 0 daily peak sun hours.
Once you have figured this out you can use one of the formulas below to calculate the best angle for your solar panels for each season.
Latitude 2 5 degrees.
Latitude x 0 9 23 5 degrees.
To get maximum energy efficiency during the winter solstice the solar panels in chicago must face south and be tilted 65 90 25.
In this way at noon the panels will be perfectly perpendicular to the sun s rays.
However the federal tax credit allows you to recover 30 of the investment as a tax credit so the net outlay is reduced to 14 000.
The more exact way to count out the best tilt angle is done as follows.
This is because the sun is always in the southern half of the sky in the northern hemisphere.
Orientation of the panels.
Whatever your latitude is you can subtract 15 from it to calculate the angle for summer.
The installed cost of a 5kw solar system is around 20 000.
Similarly you can calculate the angle for winter by adding 15.
The subsequent mathematical operation remains unchanged.
Latitude x 0 9 29 degrees.
Subtract 15 degrees from the latitude at your location during summer and add 15 degrees to your latitude during winter.
A fixed tilt solar panel does not change angles to adjust with the sun so looking at the average peak sun hours using a fixed tilt panel can set a good baseline for calculations.
There are two methods for calculating the tilt angle for solar panels.
Both of these angles require latitude degrees.
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.
There s a simple rule of thumb for calculating the best tilt angle for fixed mount solar panels.
