96Score

Infinium Solar, Roofing and Electric holds an impressive 4.9 rating from 353 reviews. Customers consistently praise their professionalism and expertise in solar installation. They are best known for their comprehensive service offerings, including roofing and electrical work alongside solar solutions. However, their premium pricing may not suit every budget.

Most of what reviewers hire it for is homeowners seeking a full-service solar installation. It serves San Jose and surrounding areas, with $15,000 to $30,000 pricing, and the honest trade-offs are higher pricing compared to competitors and limited availability for on-site consultations.
