SolarUnion

SolarUnion is a comprehensive solar services provider catering to residential and light commercial clients across California. The company offers a wide array of solar solutions, from designing and installing photovoltaic (PV) systems to conducting solar-readiness assessments and roof inspections. SolarUnion's emphasis on solar ownership is underscored by a robust 25-year performance guarantee, which encompasses components, workmanship, and system output.

Founded by Renzo Castillo and Ivan La Frinere-Sandoval, SolarUnion differentiates itself from competitors by focusing on high-performance, permanent electric consumption offset systems. This strategic approach is aimed at maximizing long-term savings for clients by fully monetizing the value of their real estate’s solar potential.

A key feature of SolarUnion's service model is its commitment to continuous system monitoring to ensure performance targets are met. This is bolstered by real-time client access to system performance data, providing transparency and assurance. In instances where systems underperform, SolarUnion is committed to resolving issues and compensating customers for any lost output.

Achieving the prestigious Diamond Certified status, SolarUnion is recognized as one of the highest-rated companies in terms of quality and helpful expertise. This certification signals reliability but does not replace the necessity for potential clients to conduct thorough due diligence. Potential clients are advised to:
- Confirm the comprehensive details of the performance guarantee, including the coverage of components and system output.
- Verify the company’s licensing and insurance status.
- Inquire about the specific terms of financing options available for system ownership.
