    I got quotes from 3 different installers before choosing CertaSun. Their focus on solar (as opposed to broad electric contracting), use of SunPower panels with microinverters, and promise to pay the SREC subsidy regardless of legislation made me choose them. They managed process, from design, to permitting, to install, to inspection, to net metering smoothly. While I had many worries going in, CertaSun was very professional. Now, I check my SunPower app every day and can see the solar generation and excess going onto the grid. Looking forward to generations of folks benefiting from my decision to go with solar.
