mySolar uses powerful, industry-leading solar design software with a strong track record for highly accurate energy production simulations. In addition, each design is personally reviewed and optimized by our Director of Solar Engineering, who has over 20 years of experience designing PV systems. We are always conservative with our power production estimates and often find that our customers experience greater energy returns than expected. However, mySolar cannot guarantee system production simply because small year-to-year fluctuations may occur.
