SuretySun Services

What SuretySun Services does

SuretySun Services is a residential solar photovoltaic and energy storage installation company based in Folsom, California. Founded in 2017 and operating under DBAs including Grand Openings Home Improvements, Surety Solar, and Optimum Solar & System Maintenance, the company sells, installs, and services solar PV systems, battery energy storage systems, and Hybrid PV & Battery combinations built around Enphase microinverter technology. The company holds Enphase Premier Installer certification, granting it access to and expertise across the full Enphase product lineage from legacy M-series units (M175 through C-250) to current IQ6/7/8 and Ensemble products, and uniquely positions it to service Enphase installations originally sold by other providers who are no longer available.

The business model is direct-to-consumer: residential customers purchase hardware (panels, inverters, batteries) and professional installation services via a quote-based, reservation-driven sales motion through the company website. Revenue is generated through hardware sales of solar PV equipment and battery energy storage systems combined with installation labor, targeting homeowners seeking energy independence, backup power, and protection from California's NEM 3.0 net metering economics. The company also derives value from a legacy-system servicing niche that most generalist solar installers do not address.

Operationally, the company is small (11-50 employees), privately held, and has not disclosed any external funding. The website indicates an out-of-date digital presence ("temporarily under construction"), with the most recent public content dating to February 2019. Management team, ownership structure, and financial details are not disclosed in the available data.
