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

How does Solar Watt 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 Solar Watt 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.

Solar Watt Solutions reviews: what customers say

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

Sales & proposal integrity

Sales Integrity8.0/10

Reviewers generally describe the sales and proposal process as clear, helpful, and professional. Most comments say expectations were explained up front and the process matched the original proposal, though there is one strong complaint about contract terms not being delivered as expected.Solar.com's composite of published customer feedback, not a customer quote

Clear proposals. Reviewers say the proposal details were easy to understand and the process and timeline generally matched what was outlined at the start. Representative review excerpt: "The proposal was clear and helpful, and I'm happy to report that the process and timeline laid out from the start was exactly what we experienced."

Professional guidance. Customers describe staff as communicative and supportive through the signing and scheduling process, including when personal delays came up. Representative review excerpt: "We had to postpone our install (after signing contract) due to personal family emergencies and a delay in renovation, and Dave was communicative and professional throughout."

Contract concern. One reviewer reports that terms were not delivered as expected after signing and describes a prolonged dispute over fulfillment. Representative review excerpt: "It is now April 2023, and Solar Watt Solutions, aka Cleanspark, aka Multitaskr, has still not delivered on the terms of the contract and my SGIP approval is about to..."

Price & financing transparency

Price Transparency7.2/10

There is one serious complaint about unresolved pricing-related concerns, so the overall picture is positive but not uniform.Solar.com's composite of published customer feedback, not a customer quote

Pricing pricing. Reviewers describe a recurring pattern in this area. Representative review excerpt: "Shopped around and their prices were competitive."

Lower-cost option. Reviewers describe a recurring pattern in this area. Representative review excerpt: "In addition, Solar Watt offered the panels & installation at a lesser cost than anyone else we interviewed."

Unresolved concern. One reviewer describes being very unhappy and says they did not get a resolution from the ownership chain on a pricing or financing-related issue. Representative review excerpt: "We are, needless to say, extremely unhappy and are getting no resolution from anyone in the chain of ownership to help us."

Communication & coordination

Communication7.7/10

Most reviewers say communication was strong, with timely callbacks, email follow-up, and clear coordination before, during, and after installation. A smaller set of complaints describes missed updates, unanswered calls, and difficulty getting help when problems came up.Solar.com's composite of published customer feedback, not a customer quote

Responsive follow-through. Reviewers describe staff as diligent about returning calls, emails, and texts and doing what they said they would do when they said they would do it. Representative review excerpt: "Joe, Dave, and Steve were extremely diligent about returning phone calls, emails, and texts and, most importantly, did what they said they were going to do when they said they..."

Clear communication through delays. Customers say the team stayed communicative and professional when installs had to be postponed or adjusted. Representative review excerpt: "We had to postpone our install (after signing contract) due to personal family emergencies and a delay in renovation, and Dave was communicative and professional throughout."

Unanswered calls. Some reviewers report long stretches without updates and difficulty reaching anyone for help, including after leaving messages. Representative review excerpt: "They don't return calls and have been completely unresponsive for the last month after calling every number that I have and after leaving a message for a return call."

Timeline reliability

Timeline Reliability7.5/10

Reviewers often say projects moved quickly, arrived on time, or finished ahead of schedule once work was underway. Complaints are less common but focus on months-long delays, limited updates, and extended waits tied to supply or activation issues.Solar.com's composite of published customer feedback, not a customer quote

Fast activation. Some reviewers say their systems were installed quickly and activated within days after inspection and utility verification. Representative review excerpt: "Our system was installed very fast, and activated within days after an easy inspection with the city and verification from SDGE."

On-schedule work. Customers also report on-time arrivals and installs that finished ahead of schedule or adapted promptly when changes came up. Representative review excerpt: "They arrived on time, and finished ahead of schedule."

Extended delays. A smaller number of reviewers describe lengthy waits with limited updates, including supply-related delays that stretched for months. Representative review excerpt: "I understand supply issues, but after 14 months without batteries, and with hardly any updates, we cannot recommend Solar Watt and are glad to be using Baker Electric, who has..."

Workmanship & site care

Workmanship8.0/10

Reviewers generally describe the installation crews as polite, skilled, and careful about explaining the work and keeping the site organized. A small number of complaints mention problematic recent projects or work that did not meet expectations.Solar.com's composite of published customer feedback, not a customer quote

Professional crews. Reviewers say the crews were polite, worked hard, and completed the installation professionally. Representative review excerpt: "Very polite, did an outstanding job, worked hard, worked fast and made sure we knew what was installed on the roof and in the garage."

Good site communication. Customers also mention being kept informed during the job and seeing careful, skilled work on site. Representative review excerpt: "Everyone wore masks, kept me informed at all times, and were clearly skilled at what they were doing."

Problem project. One reviewer describes a recent project that they say did not go well after having had a positive experience years earlier. Representative review excerpt: "We worked with Solar Watt Solutions (SWS) in the past (2015) with great results, however in our recent 2021 / 2022 project that included the installation of battery back up..."

Long-term support & performance

Long-Term Support5.0/10

This is the weakest area in the review set. Many reviewers report their systems producing as expected, but a meaningful group describes difficulty getting post-install help, warranty support, or resolution when equipment problems came up.Solar.com's composite of published customer feedback, not a customer quote

Expected production. Some reviewers say the system output met or exceeded expectations and that the installed equipment performed well over time. Representative review excerpt: "I am happy to say that my Pool Heating is working perfectly and that I am producing the Solar Energy that I expected to or more."

Helpful after install. A few customers describe useful follow-up support when they had questions about bills, production, or an inverter under warranty. Representative review excerpt: "(I gave a 5 star review on the install) When the SDGE and bill looked a bit off in Dec 2021, I called and discussed with him and he went..."

Warranty support issues. Other reviewers report trouble getting help after installation, including being routed around when seeking warranty resolution or being directed to the manufacturer. Representative review excerpt: "We are getting the runaround when we call and are trying to get help to resolve the problem covered by warranty."

Bottom line: Solar Watt Solutions scores well in sales clarity, installation quality, and overall communication, with most reviewers describing a smooth process. The main weakness in the corpus is long-term support and post-install issue resolution, where complaints are more concentrated than in the other categories. Overall, the review pattern is positive but not uniform, especially after the system is turned on.

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.
