#80 of 678 scored in California by Solar.com Installer Score

How does Peak Power Solutions compare where you live? Rankings are local; an installer that leads one city can trail in the next. See how they rank in your city →

Why this differs from star ratings: most five-star reviews say “great company” and stop, and star averages reward that. These category scores only count reviews with concrete evidence, weighted by recency and the reviewer’s track record. A company can hold a strong star average while specific categories score lower; that gap is usually where the real story is. Categories with more complaints than praise are the questions worth asking any bidder, not necessarily dealbreakers.

Where Peak Power Solutions builds

County-by-county activity from CPUC records through May 2026.

What this data covers: *Counts on this page, including the totals up top, come from investor-owned-utility interconnection records (SCE, SDG&E, PG&E). Work in municipal-utility territory, such as LADWP or city utilities, and outside California does not appear here, so this company's true totals are higher than shown. Unlike the county rankings, this profile also shows counties below the 250-install ranking floor.

Sales & proposal integrity

Sales Integrity7.7/10

Reviewers most often describe the sales process as clear, patient, and low-pressure.

Price & financing transparency

Price Transparency6.7/10

Representative review excerpt: "I was sold on the deal my energy bill would be in the area of 25 to 50 dollars per month only to find out my system saved me 25..."

Missed communication. A small set of complaints says calls or emails were not returned, or that customers had trouble getting follow-up after problems came up. Representative review excerpt: "Needless to say the owner will not return my calls or e-mails they have my money and i have their trash."

Timeline reliability

Workmanship & site care

Workmanship8.6/10

Long-term support & performance

Long-Term Support8.6/10

Post-install feedback is mostly favorable, with reviewers describing reliable follow-up, helpful support, and systems that are performing as expected.

Helpful post-install support. Reviewers often say the company continued to help after installation and remained responsive to future solar needs.

Warranty or service concerns. A small number of reviewers report confusion or frustration around warranty expectations or post-install troubleshooting.

Bottom line: Peak Power Solutions’ review profile is broadly positive, with especially strong feedback on workmanship, long-term support, communication, and project coordination.

Important context: this chart shows investor-owned-utility records only. Companies that shift work toward municipal-utility territory (LADWP and city power departments) or other states will show declining bars here even while building steadily elsewhere, and 2025-26 records also lag real installation dates. Treat this as a partial window, not the company's full trajectory.

How we built this data

Methodology: Counts are residential PV interconnections in investor-owned-utility territory (PG&E, SCE, SDG&E) per CPUC Rule 21 public records through May 2026. Postal and name variants are merged. Municipal utility territory such as LADWP, Glendale, Pasadena, Burbank, Anaheim, and Riverside Public Utilities is not included in those CPUC counts. Counts show recorded installations, not quality ratings. Reported costs are self-reported on owned-system interconnections. No installer can pay for placement.

Who we are: Solar.com is a solar marketplace — we connect homeowners with installers and earn a fee when projects move forward. These rankings and scores are computed from public installation records and published customer reviews. No installer can pay for placement, and no installer — including those we work with — can pay to change a score.
