If you purchase your system, this “payback time” depends entirely on the size and cost of your system and the amount of your utility rates.

In New Jersey and New York, average payback times we see are between 5 and 6 years. In Pennsylvania, average payback times are between 7 and 10 years. Considering the average life of a solar installation is 30 years, these payback times mean you’ll have 20 to 25 years of paying $0 for your electricity.

When we estimate these payback times, total savings, and return on investment, we take into consideration a 3% annual increase of utility rates over the next 30 years, because historic figures have actually been higher, showing a 5% increase over time.
