Best Angle For Solar Panel In Michigan

The more exact way to count out the best tilt angle is done as follows.

Best angle for solar panel in michigan.

Latitude x 0 9 23 5 degrees. This is because the sun is always in the southern half of the sky in the northern hemisphere. The result for chicago is 90 42 23 25. The costs and savings for a 5 kw pv system in michigan can be broken down as follows.

In this way at noon the panels will be perfectly perpendicular to the sun s rays. The installed cost of a 5kw solar system is around 20 000. Orientation of the panels. Latitude 2 5 degrees.

Latitude x 0 9 29 degrees. On average the state of michigan receives 4 0 daily peak sun hours. For a latitude up to 25 take your latitude and multiply it by 0 87 for a latitude between 25 to 50 take your latitude multiply by 0 87 after that you will add 3 1 degrees for a latitude over 50 the most ideal angle will end up being approximately 45 degrees. 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.

To get maximum energy efficiency during the winter solstice the solar panels in chicago must face south and be tilted 65 90 25. Similarly you can calculate the angle for winter by adding 15. For the best results solar panels should be oriented towards the south. Both of these angles require latitude degrees.

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. Both the slope and the orientation is critical for best meeting your needs. 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. The answers you end up with are the best angles for each particular season.

For a precise method use the second formula on this page to calculate tilt angle. 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. Whatever your latitude is you can subtract 15 from it to calculate the angle for summer.

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.
