Cromwell Solar

Cromwell Solar is one of the oldest continuously operating solar installation firms in the United States, founded in 1982 as part of Cromwell Environmental. Headquartered in Lawrence, Kansas, they have over four decades of experience designing and installing photovoltaic systems across Kansas and Missouri—with select large-scale projects extending throughout the Midwest.
The company specializes in turnkey EPC services for residential homes as well as commercial/industrial clients—including farms, schools, nonprofits/churches/government buildings—and has completed more than 3,000 installations totaling over 13.5 MW at sites such as Fort Riley military base. Their expertise covers rooftop arrays (including flat roofs), ground mounts, carports/pergolas/barns/outbuildings—even challenging or custom-engineered sites.
Cromwell’s staff includes multiple NABCEP-certified professionals; all work is performed by their own personnel rather than subcontractors to ensure quality control. They are known regionally both for technical innovation—such as proprietary system modeling software ensuring optimal sizing/payback—and advocacy/education efforts that help shape local regulations to benefit customers.
In addition to core PV installation services they offer battery backup solutions (e.g., Tesla Powerwall), generator integration for energy resilience during outages or off-grid needs; EV charger installs; comprehensive financing support including no-money-down options; ongoing maintenance/repairs; remote monitoring setup even where internet access is limited; plus environmental consulting via their parent organization.
Their reputation rests on long-term reliability—many systems installed decades ago remain operational today—and a commitment to customer education/support throughout the project lifecycle.
