ES Solar

ES Solar has built one of the largest residential solar practices in the Intermountain West since the company's 2009 founding, with deep service coverage across Utah and Idaho and a 4.6-star Google rating spanning approximately 4,000 verified reviews — by a wide margin the largest verified review base of any installer active in Idaho's residential market. That review-base scale is meaningful because it reflects a sustained book of completed projects across more than a decade and a half of operation rather than recent marketing-driven scale.

What stood out is the operational depth that comes with that scale. ES Solar runs a turnkey residential model — design, permitting, equipment specification, installation, interconnection, and warranty service — with an installed equipment line that includes tier-one panels and Tesla Powerwall and Enphase battery storage. The company's NABCEP-certified team, dedicated Idaho service area, and longstanding presence in the Utah-Idaho solar market give homeowners shopping in the Treasure Valley or the Magic Valley access to a regional installer with substantially more accumulated project experience than the typical Idaho-headquartered competitor.

Prospective customers should know that ES Solar is not an Idaho-headquartered company — the Layton, Utah home office means warranty service and follow-up scheduling work across state lines, and that introduces logistical friction relative to a fully in-state installer. The 4,000-review base also necessarily includes a wider spread of customer outcomes than a smaller installer's review pool, and our research team would specifically recommend prospective customers read recent one-star and two-star reviews carefully to understand the company's response patterns on the projects that did not go smoothly. Buyers should ask about Idaho Power interconnection lead times from a Utah-based project management team, the assigned Idaho-licensed crew composition for their specific project, and how warranty truck-rolls are dispatched into Idaho from the Layton headquarters.

The combination of fifteen-plus years of operation, NABCEP credentials, dedicated Idaho service coverage, and the largest verified review base of any installer in this state ranking gives ES Solar a credible third-place position in our 2026 Idaho list.

With a composite score of 68.5 out of 100, ES Solar holds the third-ranked position in Idaho for 2026.
