How does Sespe 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 Sespe 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.

Sespe Power Solutions reviews: what customers say

An independent synthesis of published customer feedback across Google and Yelp, updated September 23, 2026. Green marks praise, amber mixed experiences, red complaints.

Sales & proposal integrity

Sales Integrity7.4/10

Reviewers describe SESPE Power Solutions as generally clear and thorough in the sales process, with multiple mentions of taking time to explain options and adjust project scope. The overall pattern is positive, though the score sits just below 7.0, so the feedback reads as solid but not flawless.Solar.com's composite of published customer feedback, not a customer quote

Clear explanations. Reviewers say the team took time to explain the proposal and answer questions in detail, which helped set expectations before work began. Representative review excerpt: "Ish was always very professional and very knowledgeable about what we needed for our home and spent a lot of time explaining his proposal as well as going over the..."

Flexible project design. Some reviewers describe the company as willing to revisit system size and design choices during the planning stage rather than pushing a one-size-fits-all proposal. Representative review excerpt: "They took the time to explain things multiple times to us, tinkered with the scale of the project multiple times, and had a streamlined financing process that was much easier..."

Professional consultation. Reviewers also report that the initial consultation felt knowledgeable and tailored to the home’s needs. Representative review excerpt: "Here is my journey from start to finish--and why I'm extremely happy with the result: Initial Consultation: Ish recommended a design that allowed me to install more solar panels than..."

Price & financing transparency

Price Transparency7.0/10

Feedback on pricing and financing is mostly favorable, with reviewers describing straightforward explanations and a smoother financing process. There are no tallied complaints in this category, but the score suggests the subject is not universally effortless for every customer.Solar.com's composite of published customer feedback, not a customer quote

Financing explained clearly. Reviewers say the team spent time walking through financing details and making the process easier to follow. Representative review excerpt: "They took the time to explain things multiple times to us, tinkered with the scale of the project multiple times, and had a streamlined financing process that was much easier..."

Helpful with rebate timing. Some reviewers report help with rebate timing and say their questions were answered after installation. Representative review excerpt: "He also was very helpful in getting our battery rebate in a timely manner as well as answering my many questions after the install."

Monthly cost understood. A few customers say they were able to understand their final monthly cost after installation and financing were in place. Representative review excerpt: "Now, after having the solar installed for the last 10 months I can tell you my final monthly cost between the financing, which will be paid off before you know..."

Communication & coordination

Communication7.8/10

Most reviewers describe SESPE as responsive, organized, and easy to reach during the project. There is one complaint in the review set, so the overall pattern is strongly positive but not uniform.Solar.com's composite of published customer feedback, not a customer quote

Responsive team. Reviewers commonly describe the company as fast to respond and straightforward to work with when questions came up. Representative review excerpt: "Fast, knowledgeable, responsive, and genuinely great to work with."

Clear project updates. Some reviewers say they were kept informed about where they were in the process and felt the handoffs were well managed. Representative review excerpt: "But Ish and his team are there if you have questions and will let you know where you are in the process."

One service complaint. A small number of reviewers report poor customer service and missed scheduled service, which stands out against the otherwise positive feedback.

Timeline reliability

Timeline Reliability6.5/10

Timeline feedback is mixed: many reviewers say projects moved on schedule or ahead of expectations, but permit and utility approval delays show up often enough to affect the category score. The complaint pattern is mainly about waiting on permits, paperwork, and activation steps rather than installation quality.Solar.com's composite of published customer feedback, not a customer quote

On-time work when scheduled. Some reviewers say crews arrived on time and completed work within the timeframe they were given. Representative review excerpt: "Sean and Chad arrived on time and completed replacing our electrical panel in the exact time frame given."

Project deadlines met. Reviewers also note cases where the project manager kept the job moving and met deadlines tied to the installation process. Representative review excerpt: "They did a fantastic job and everyone on the project was great - Ish managed our project from start to finish and met all the deadlines to lock in our..."

Permit and approval delays. Other reviewers report that permits and utility approval took a while, and that the paperwork process could be frustrating. Representative review excerpt: "Took a while to get permits and Edison approval."

Workmanship & site care

Workmanship8.3/10

Reviewers consistently describe the installation work as strong, with good cleanup, professional crews, and systems that were completed correctly. There are no tallied complaints in this category, so the feedback reads as broadly positive.Solar.com's composite of published customer feedback, not a customer quote

Systems installed cleanly. Reviewers say full solar and battery systems were installed successfully and were working well after completion. Representative review excerpt: "They installed a full solar system for us, including battery backup and the system is working great a month in."

Crew cleanup and professionalism. Some customers note that the crew cleaned up after the workday and returned as promised to finish the job. Representative review excerpt: "Cleaned up after the day and said they would be back in a few days to finish, and they did."

Problem-solving on site. Reviewers also mention the team fixing ongoing issues during the job rather than leaving them unresolved. Representative review excerpt: "They fixed an ongoing problem that no one."

Long-term support & performance

Long-Term Support8.3/10

Post-install feedback is very strong, with reviewers describing systems that are working well and follow-through that continued after turn-on. The review set does not show a notable complaint pattern here, though the score suggests customers especially value the company’s responsiveness after installation.Solar.com's composite of published customer feedback, not a customer quote

Systems working well. Reviewers say their solar and battery systems were performing well after installation and that the setup met expectations. Representative review excerpt: "They installed a full solar system for us, including battery backup and the system is working great a month in."

Responsive after install. Some customers describe the team as knowledgeable and responsive when questions came up after the job was done. Representative review excerpt: "Fast, knowledgeable, responsive, and genuinely great to work with."

Stayed until everything worked. Reviewers also report that the crew stayed on site to make sure everything was operating correctly before wrapping up. Representative review excerpt: "It wasn’t an easy job but they stuck around to make sure that everything was working right."

Bottom line: SESPE Power Solutions earns a 8.3/10 on Solar.com across 60 substantive reviews, with especially strong marks for workmanship and long-term support. The main softer area is timeline reliability, where reviewers more often mention permit and utility-approval delays, while communication, pricing clarity, and sales transparency are generally viewed positively.

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.
