With renewable-energy experience dating to the 1980s, the company handles projects with its own local crew, working under its master electrician’s license.

Its offerings include residential, commercial, agricultural, and off-grid solar, as well as carports and ground-mounted systems. Customers can also get battery backup, EV charger installation, generators, electrical work, panel upgrades, solar repairs, inverter replacements, system upgrades, and detach-and-reset services. iSolar provides project planning, financing and incentive guidance, and free online tools for estimating savings, system size, payback, battery needs, and commercial returns.

The company is Solar Insure certified and offers insurance-backed, 30-year system protection. It also holds BBB A+ accreditation and certifications from organizations and manufacturers across solar, storage, EV charging, and generators. iSolar reports a 4.9 Google rating and supports income-qualified solar, farm, school, and public-building projects.
