Alaska Solar

📍 Anchorage, AK

Alaska Solar is a solar installation company based in Anchorage, Alaska, serving both residential and institutional clients throughout the state. Their completed projects include residential installations in Anchorage, Palmer, and the Airport Heights neighborhood, as well as larger-scale work for the CEA Southcentral Power Plant and the Chickaloon Village Traditional Council, indicating experience across a range of project types and sizes. The company positions its services around three practical benefits specific to Alaska: reducing electricity costs (noting that Alaskans pay roughly 1.5 times the national average for power), generating property-tax-free savings on energy bills, and building household energy independence amid the state's ongoing natural gas supply challenges. Rather than using a traditional sales team, Alaska Solar sends experienced solar design consultants directly to a prospective customer's site. These consultants review the customer's energy usage, assess the specific location, and develop custom solar designs tailored to individual goals. This evaluation is offered at no charge and is described as no-pressure. Prospective customers can request a free assessment through the company's website.
