Certasun Reviews
Certasun is a regional residential solar company based near Chicago that also sells EV chargers, home batteries, and service work. Public information on the company is limited, so if you’re in the Chicago or Milwaukee metro area it’s worth confirming who will do the installation and handle long‑term maintenance — installer experience can vary a lot between local outfits and national brands like Sunrun or SunPower.
Best for: Metro homeowners wanting local service
Service area: Chicago & Milwaukee metros (IL/WI)
Financing: Varies
Our review summary
Certasun presents as a small regional player centered on the Chicago and Milwaukee metros that bundles solar with batteries and EV chargers. Because source information is thin, it’s hard to judge consistency across jobs; your experience may hinge on the local crew assigned to your home. If you’re comparing proposals from national firms such as Sunrun, Tesla Energy Solar, or SunPower, weigh Certasun’s local familiarity against the broader resources and warranties larger companies advertise. Ask for references from recent installs in your area, confirm who the contractor is, and get service contacts in writing so you know who handles repairs later.
Common homeowner complaints
Available public data is limited and doesn’t show a clear pattern of issues. Certasun is BBB accredited since 2019, but accreditation alone doesn’t reflect current service levels in your neighborhood. Before you commit, check recent local reviews and the BBB complaint history for the company’s office that would serve your address.
Pricing and financing notes
Pricing and financing options weren’t specified in the available profile. Expect quotes to depend on your roof, energy use, and the financing path you choose. Ask for a full written estimate that breaks down equipment, labor, incentives, and any loan or lease terms, and compare several proposals.
Who this company may be best for
Homeowners in the Chicago and Milwaukee metro areas who prefer working with a regional installer and want a single company to handle solar plus battery and EV charger equipment. Certasun may appeal to people who want local attention rather than a national call center. That said, because public information is sparse, this is a fit only if you’re willing to do a bit more homework: verify the local installation team, request nearby references, and confirm ongoing service and warranty contacts in writing before you sign any agreement. If you prefer a company with a large public footprint and many national reviews, also get bids from Sunrun, Tesla Energy Solar, or SunPower for comparison.
