The Best Angle for Solar Panels

By January 10, 2020 February 10th, 2020 Solar Panel Tips

If you are a home or business owner who took the leap into solar energy, then you likely want to get the best return on your investment. And while properly installed solar panels will do their job of transferring sunlight into electricity, there are ways that you can adjust them ever so slightly to increase their solar energy output.

Because the angle of the sun changes depending on the time of day and season of the year, you’ll need to vertically tilt your panels to be perpendicular to the sun’s incoming rays to maximize electricity production.

Why Solar Panels Need a Tilt Angle

During the summer, the sun is higher up in the sky compared to during the winter. Positioning your photovoltaic panels at an average position between the two seasons will maximize your electricity production. This position has a close relationship with the latitude of the location where you are going to house the panels. When you establish this position, you can get the maximum electricity from the sun all year round.

How to Calculate the Tilt Angle for Solar Panels

You can calculate your solar panel’s tilt for each season using the following methods.

  • Summer angle – When calculating the tilt angle for your solar panel during summer, subtract 15 degrees from your latitude.
  • Winter angle – Add 15 degrees to your latitude when calculating the angle during winter.
  • Autumn/Spring angle – Subtract 2.5 degrees to get the angle during fall or spring.

A second method of calculating your solar panel’s tilt accounts for changes in season and midday sun when it is hottest during the day. This method involves multiplying your latitude by 0.9 and adding 29 degrees for winter. For summer, you subtract 23.5 degrees after you have increased your latitude by 0.9. The results from the second method have a variance of plus or minus 10 degrees from those of the first.

Optimal Tilt for Solar-Powered Homes in Florida

By understanding the correct angle for your solar panels, you will get the most out of your investment. For maximum year-round production, the optimal angle for solar panels in Florida homes is 28 degrees from the horizontal, facing to the south. Homeowners can, however, adjust their solar panels to optimize power production based on the demand for electricity in their homes.
