What SunPower by E2 Solar does
SunPower by E2 Solar (legally E2 Solar) is a privately held, regional solar PV installer founded in 2008 and headquartered in South Dennis, Massachusetts. The company designs and installs custom photovoltaic solar energy systems for residential and commercial customers on Cape Cod and across southeastern Massachusetts, operating a turnkey model that covers site assessment, system design, permitting assistance, installation, and activation. As a Maxeon preferred partner, E2 Solar primarily deploys Maxeon panels — featuring a patented solid copper foundation, cell efficiencies above 22%, a 40-year warranty, and an industry-low 0.2% annual degradation rate — alongside REC photovoltaic modules.
The company's core revenue stream is one-time installation and sale of solar energy systems, with pricing quoted per project rather than published and customers accessing the business via phone, website quote forms, and direct outreach. E2 Solar employs approximately 10 people with over 80 years of combined solar installation experience, including a Master Electrician, a LEED-accredited architect, and a dedicated lead installer. The customer mix spans long-tail residential homeowners, small-to-mid-market commercial clients across industries such as agriculture, retail, healthcare, and construction, plus a sustained affordable-housing partnership with Habitat for Humanity of Cape Cod covering 36 homes. Financing is offered through Cape Cod 5 Solar Loans, UMass Five MySolar Loans, and MassSave HEAT Loans for battery backups.
E2 Solar relies on third-party financing partners and federal/state solar tax incentives (30% federal through 2032, 15% Massachusetts state credit up to $1,000) to support conversion. Distribution is fully direct-to-consumer within a single geography, with no retail or marketplace presence, no app or API offering, no disclosed institutional funding, and no public pricing. Marketing is concentrated on the company's website, Yelp, Google Reviews, and a Facebook page. Operating since 2008, E2 Solar has accumulated thousands of installations and over 3,000 kW of deployed capacity across the region.
