ECG Solar

ECG Solar has spent more than fifteen years building a dedicated residential solar practice anchored in eastern Iowa, with a Cedar Rapids-area service core out of Anamosa and continuous operation since 2008. That tenure — through multiple federal incentive cycles, the 2017 solar tariff turbulence, and the COVID-era supply-chain disruption — gives ECG Solar one of the longer continuous-operating histories among Iowa-headquartered residential solar installers, and the company has translated that experience into a 4.9-star Google rating across more than 220 verified reviews.

What stood out to our research team is the breadth of in-house energy offerings paired with a clear residential PV focus. ECG installs Tier-1 photovoltaic panels and ACPV (AC-coupled photovoltaic) systems, Enphase battery storage, EV chargers, and Kohler standby generators — a full home-energy stack that homeowners can specify under a single contract with a single warranty point of contact. The company's marketing materials emphasize a 'tailored, personalized solutions' approach and certified employees, and the residential focus is consistent across the website's offerings rather than buried beneath a roofing or insulation primary business line.

Prospective Iowa customers should know that ECG's published documentation is somewhat lighter on credential specifics than the leading national installers, and our research team would specifically recommend asking about NABCEP team certification, MidAmerican Energy or Alliant Energy interconnection experience in the homeowner's specific service territory, and warranty service dispatch from Anamosa to the western Iowa markets. The Kohler dealership credential is a real signal of vetting discipline because Kohler's standby generator dealer program requires technical training and ongoing performance review — capabilities that translate cleanly into the kind of electrical install precision residential PV requires.

As an Iowa-headquartered company with seventeen years of operating history, ECG Solar brings firsthand knowledge of Iowa's net-metering rules, the recent Rate Tariff developments at the state's investor-owned utilities, and the specific permitting requirements that vary across Iowa's mix of municipal and IOU service territories.

With a composite score of 73.0 out of 100, ECG Solar holds the second-ranked position in Iowa for 2026.
