"I had solar panels installed by SunPower's subcontractor Hooked on Solar in 2020. In 2023 some of the panels were damaged by an electrical outage and surge. It took about 4 months for Hooked on Solar to identify the damaged panels, schedule an appointment to replacement, but finally they fixed the panels."
