We’ve been asked about the lower production days in June that come as a result of the so called “June Gloom”
When we design your system and project it’s yearly output, many factors are used. One is the weather. Your zip code has a historic rating based on sunny days, over cast days, rain days and many weather factors, also hours the sun is up. This information is used in sizing your system and estimating production. Your system it site specific designed for your historic conditions.
Hope this helps answering your questions.
