Take a ride on the Solar Coaster!
The solar power production of a solar Tracker varies greatly from month to month. Days in December (in New England) are much shorter than in June. In December, each day lasts only about 9 hours. In June, each day lasts more than 15¼ hours, 70 percent longer than December’s day length. (Learn more about solar and daylight here.)
In addition, weather patterns change throughout the season. These are not as reliable as the length of day, but we do tend to have cloudier weather in December which exacerbates that month’s low production.
Putting those factors together, you’ll understand why the number of kWhs generated from a Tracker will be quite different at different times of year.
A Typical Year of Solar Power Production
The chart below shows the solar power production from one of our customers’ residential solar Trackers over a two year period. A peak month’s energy generation can be more than four times that of a minimal month, and seasonally summer is nearly twice as productive as winter.
Most solar Tracker customers build up credit with their utility during the summer and use this credit to help offset winter electric bills.
