How does Earthwise Energy 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 Earthwise Energy 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.

Earthwise Energy Solutions reviews: what customers say

An independent synthesis of published customer feedback across Google and Yelp, updated September 28, 2026. Green marks praise, amber mixed experiences, red complaints.

Sales & proposal integrity

Sales Integrity7.6/10

Reviewers generally describe Earthwise Energy Solutions as thoughtful and clear in the sales process, with multiple comments about careful needs analysis, reasonable options, and low-pressure guidance. The main complaint pattern is limited, but one reviewer said the down payment request and initial quote were not handled cleanly.Solar.com's composite of published customer feedback, not a customer quote

Needs-based proposals. Reviewers say the company takes time to understand project goals and present options that fit the home and budget, rather than pushing a one-size-fits-all package. Representative review excerpt: "They were great at analyzing my needs and helped me to figure out what I needed and gave me reasonable options."

Low-pressure guidance. Several customers describe the sales experience as knowledgeable and not pushy, with explanations that helped them feel informed before moving forward. Representative review excerpt: "Even though I ended up going with a different company, I have to say Larry is extremely knowledgeable, and I never felt like I was being sold to or pressured..."

Proposal and deposit concern. One reviewer reported concerns about the requested down payment and said the initial proposal was incomplete for a straightforward project. Representative review excerpt: "They asked for several times California's $1,000 down payment maximum, and their initial quote was incomplete, for a pretty straightforward project."

Price & financing transparency

Price Transparency6.8/10

Feedback on pricing and financing is more mixed than the other categories. Many reviewers describe the pricing as fair for the service level, while a smaller set raise concerns about deposits, quote completeness, and how costs were presented.Solar.com's composite of published customer feedback, not a customer quote

Value for service. Reviewers describe a recurring pattern in this area. Representative review excerpt: "They were mid-range in price, but we got top of the line service."

Detailed cost discussion. Some reviewers describe a thorough estimate process that incorporated site information and bill history, which helped them understand the proposed system cost. Representative review excerpt: "The Earthwise prospectus was based on a "survey" of our house made with google maps and a detailed review of a year's worth of our PGE bills."

Deposit and quote issue. One reviewer reported that the company asked for more than the state down payment limit and said the initial quote was incomplete. Representative review excerpt: "They asked for several times California's $1,000 down payment maximum, and their initial quote was incomplete, for a pretty straightforward project."

Communication & coordination

Communication7.8/10

Communication is a consistent strength in the review corpus. Reviewers commonly describe responsive follow-up, clear explanations of the process, and good ownership of questions and coordination; only a small number mention coordination problems.Solar.com's composite of published customer feedback, not a customer quote

Responsive support. Reviewers frequently say Jason and the team were quick to respond and easy to reach with questions throughout the project. Representative review excerpt: "Jason the owner is very responsive and has excellent customer service."

Clear process explanations. Customers describe being walked through options and approvals in a way that made the project easier to follow and less confusing. Representative review excerpt: "Jason patiently and enthusiastically walked us through all of our options, as well as explained the entire installation and approval process to us."

Coordination hiccup. One reviewer reported duplicated visits after measurements were lost and said that created an avoidable coordination problem. Representative review excerpt: "They took project measurements on the first visit, then seemed to lose the measurements and want to send people back (and bill me for the duplicated visits)."

Timeline reliability

Timeline Reliability7.3/10

Most reviewers say schedules were handled well, with projects completed on time or without unexpected delays. A small number of comments note that installation and inspection can take longer than expected, especially during busy periods.Solar.com's composite of published customer feedback, not a customer quote

On-time delivery. Several reviewers say the project was executed on schedule and that the work stayed within the expected timeline. Representative review excerpt: "The project was well communicated and executed on time and within budget."

Planning reduced delays. Customers also describe careful upfront planning that helped avoid unexpected delays during installation and permitting. Representative review excerpt: "From the very beginning to the very end, every detail of the installation was thought out in advance so there were no unexpected delays along the way or issues with..."

Longer-than-expected finish. One reviewer said the installation and county inspection were completed later than expected, pointing to timing pressure near the end of the year. Representative review excerpt: "We didn't get our system installed until Election Day in November, and the final inspection from the County took place only in early December."

Workmanship & site care

Workmanship8.0/10

Reviewers are strongly positive about the installation crew’s professionalism and the quality of the finished work. The available feedback emphasizes careful placement, knowledgeable crews, and clean, well-executed installations, with no recurring site-care complaints in the corpus.Solar.com's composite of published customer feedback, not a customer quote

Professional crew. Customers describe the installation teams as professional, knowledgeable, and pleasant to work with during the job. Representative review excerpt: "It's a relief and a joy when you contract with someone who is professional and knowledgeable, committed to promises and extremely pleasant."

Careful installation. Reviewers note that the crew paid attention to placement and finishing details, which contributed to a polished install. Representative review excerpt: "When it came to installation, the team working on the project were professional, full of information (I ask a lot of questions), fast, and very conscious of placement and dressing..."

Repeat-project trust. Some customers mention returning for additional work over time, suggesting confidence in the company’s installation quality. Representative review excerpt: "This review is long overdue as I have worked with Jason and his crew for several years now, first to install a battery on an existing system, later to add..."

Long-term support & performance

Long-Term Support8.3/10

This is Earthwise Energy Solutions’ strongest area in the review set. Customers consistently report solid system performance after activation, successful battery operation during outages, and follow-through on later support needs.Solar.com's composite of published customer feedback, not a customer quote

Reliable system output. Reviewers say the system performs as expected after installation and that the end result met their goals. Representative review excerpt: "Earthwise did a wonderful job working on and completing a rather large and complicated solar & battery install at my family’s home."

Battery backup works well. Customers describe battery backup engaging quickly during outages and keeping the home running without interruption. Representative review excerpt: "When we had a power outage the battery kicked in within seconds and everything continued to run very promptly."

Post-install satisfaction. Several reviewers mention being happy with the finished system even after real-world operating conditions and utility-related challenges. Representative review excerpt: "Despite challenges with PG and E I'm happy with the end result."

Bottom line: Across 73 substantive reviews, Earthwise Energy Solutions earns especially strong feedback for long-term system performance, workmanship, and communication. The main softness in the corpus is price and financing transparency, where a few reviewers raise concerns about deposits, quote completeness, and cost presentation, while most other categories remain clearly positive.

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.
