SolarUnion provides a complete range of solar services for residential and light commercial clients throughout California. The company designs, sells, installs, and operates photovoltaic (PV) solar systems and battery (storage) backup solutions using proven technology from manufacturers with strong warranties. Its certified solar technicians are trained in-house to conduct solar-readiness audits, savings estimates and roof inspections; perform electrical panel upgrades; install solar electric vehicle charging stations; and more. In the face of increasing challenges from global warming, SolarUnion helps diverse property holders reduce their carbon footprint, constantly adapting the latest technological tools to further that process.

With a vast knowledge of financing options, SolarUnion helps customers own their systems from Day 1 while providing a comprehensive performance guarantee, with reliable warranties and complimentary monitoring, to add transparency and assess system performance. This solid path to energy independence and financial gains for homeowners has been critical for the company’s success.

SolarUnion provides a 25-year, bumper-to-bumper performance guarantee, which beats competitors who only offer standard manufacturers’ warranties or limited 10-year workmanship guarantees. “Our 25-year roof attachment guarantee is second to none,” emphasize Founders Ivan La Frinere-Sandoval and Renzo Castillo. “All of our warranties are transferable.”
