GUARANTY SOLAR’s best-practices approach to residential solar installation is born from our solar O&M roots. We have years of first-hand experience resolving installation related issues. A proper installation is fundamental to a lifetime of maximized system performance and lower operating costs. Our approach to the construction of each system we install ensures top performance and an aesthetic appearance to match that quality.

Prior to Guaranty Solar Technology’s installation offerings, our sole focus was O&M. Our technicians specialized in repairing and servicing thousands of problematic residential systems, providing us insight into the poor practices prevalent in our industry. By resolving the issues that homeowners inherited from poor installation, we gained a deep appreciation for high quality execution of Engineering, Procurement and Construction. Many leading solar providers use our contracted installation services due to our knowledge, reliability, and quality workmanship. We pride ourselves on being utilized as the support system for these companies, and stand behind our work with a 100% satisfaction guarantee. All work is covered by a ten-year workmanship warranty, and we act on behalf of our clients to facilitate manufacturer warranties when necessary. Our service coverage has expanded to include projects throughout California, while being consistent and competitive in our pricing.
