Powerfull Solar

Provisional grade. The California C-10 license is clear, but the business is recent and key buyer evidence, including warranty terms, verified volume, and a visible complaint count, is missing.

Powerfull Solar is a Los Angeles corporation that BBB dates to 2022, with a clear California C-10 license issued that same year. It says it serves eight California counties and has helped thousands of Californians. That is the company's own number, we treat it as a claim. No employee, installation, or MW figure was published, and it did not match the 2026 California contractor ranking. The public pages also do not state a workmanship or production warranty, while BBB does not display a complaint count. The company is licensable and operating, but the record is too incomplete for a buyer to skip hard questions.

The evidence

LongevityVerified

BBB lists business start on April 25, 2022 and incorporation on February 1, 2022. The CSLB license was issued April 25, 2022. This is a relatively recent operating record, so current project references matter more than claims about broad experience.

Complaints and enforcementPending verification

BBB gives the company an A+ rating but shows it as not accredited and does not state a complaint count. No company-specific news, litigation, or regulatory action was found in the research. The missing count means this cannot be treated as a verified clean complaint record.

Verifiable volumeCompany claim

Powerfull Solar says it has helped thousands of Californians. That is the company's own number, we treat it as a claim. It publishes no employee, install-count, or MW figure, and it did not match the 2026 Top California Solar Contractors list. Eitai Abutbul is identified as owner, but ownership disclosure is not volume evidence.

License statusVerified

CSLB lists Powerfull Solar Inc as a corporation with C-10 license 1090661, CLEAR status, issued April 25, 2022 and expiring April 30, 2028. BBB repeats the same license number. The research also found Powerfull Electric Inc and Powerfull Systems Inc in the C-10 extract, but could not verify their relationship to Powerfull Solar Inc.

Warranty termsPending verification

No workmanship or production warranty was published on the reviewed about and who-we-are pages. Do not assume a manufacturer equipment warranty answers the labor question. Ask for the installer warranty, its duration, exclusions, and who handles a roof leak or inverter failure.

How to read this

The license check is straightforward, and it should be the opening page of your diligence file. Then ask a tougher question: what exactly is covered after the install crew leaves? Get a written workmanship term, equipment list, warranty administrator, and roof-responsibility clause. Ask for recent projects in your county, not a general claim about thousands of customers. Finally, ask whether Powerfull Solar has any operational relationship with Powerfull Electric or Powerfull Systems, since the research could not confirm one. Our full rubric, including how our own installation business gets graded on the same scale, is on the methodology page. We are a solar installer and we partner with other solar companies. Grading is structurally separated from revenue; see disclosures.
