How does Celestial Solar & Water Systems 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 Celestial Solar & Water Systems 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 Integrity7.0/10

Reviewers mostly describe clear proposals, helpful explanations, and follow-through on what was promised. A smaller set of complaints focuses on quote changes, contract expectations, and a few disputes over how terms were handled.Solar.com's composite of published customer feedback, not a customer quote

Clear explanations and follow-through. Many reviewers say the sales process was straightforward and that the team explained the system well before work began. Some also report that the finished work matched the original proposal. Representative review excerpt: "Great communicators, good price, on time, Dennis was great at everything and explaining things."

Promises matched the installed scope. Several customers describe the company as delivering the specific items discussed in the proposal, with work completed as described after signing. Representative review excerpt: "They did everything they said they would do, put in critter guard, ran the conduit through the attic and had it up in a month of me signing the contract."

Quote and contract surprises. Complaint reviews point to revised pricing, disputed expectations, and concerns about how contract terms were presented or enforced. Representative review excerpt: "After giving me an initial quote, they came back and said they underpriced it because they “didn’t realize” my roof wasn’t a shingle roof."

Price & financing transparency

Price Transparency4.6/10

Reviews on pricing and financing are notably mixed to negative.Solar.com's composite of published customer feedback, not a customer quote

Unexpected charges and refund disputes. Complaint reviews describe added charges after work started, billing disputes, and unresolved refund concerns tied to service or warranty issues. Representative review excerpt: "After the job started, extra charges were added, the work wasn’t done as described, and the company kept changing its explanation instead of fixing the issue."

Reasonable pricing for some jobs. Reviewers describe a recurring pattern in this area. Representative review excerpt: "Price was reasonable and explained how the system worked."

Pricing estimates reported. Some customers describe receiving pricing that compared well with multiple estimates, with the work and materials framed as a good value. Representative review excerpt: "I received over ten different estimates from the leading solar companies and not only was Celestial competitive with the most competitive prices, but offered higher quality materials and completes all..."

Communication & coordination

Communication7.1/10

Reviewers mostly report responsive communication, timely callbacks, and smooth coordination from quoting through project completion. Complaints are present but less common, and they focus on missed callbacks, limited phone contact, or occasional blunt handoffs.Solar.com's composite of published customer feedback, not a customer quote

Responsive and helpful updates. Many reviewers say the team communicated clearly, answered questions, and kept them informed during the project. Several also mention helpful explanations during the sales and installation process. Representative review excerpt: "Great communicators, good price, on time, Dennis was great at everything and explaining things."

Service calls handled well. Some customers describe fast issue resolution and say the crew was easy to work with after the initial appointment. Representative review excerpt: "arrived on time: resolved the issue quickly: Perfect service call!"

Callback and contact issues. Complaint reviews describe situations where customers could not get a phone response, were told they would receive a callback that never came, or felt communication was one-sided. Representative review excerpt: "When you call them on the phone you are told you will get a call back but that never happens either."

Timeline reliability

Timeline Reliability7.2/10

Most reviewers report that appointments, installation dates, and completion timelines were met as expected. A smaller set of complaints mentions scheduling delays, early or late arrivals, and occasional no-show concerns.Solar.com's composite of published customer feedback, not a customer quote

Appointments and installs kept on schedule. Many reviewers say the company showed up when promised and completed installations quickly once work was scheduled. Representative review excerpt: "They actually showed up when they said they would and they were friendly a d helpful."

Fast scheduling after approval. Some customers report that installation was set very soon after accepting the quote and that the work moved ahead without much delay. Representative review excerpt: "Upon my accepting the quote, an installation date was scheduled for the following week!"

Scheduling delays and missed timing. Complaint reviews mention wait times for appointments, arrivals outside the promised window, and cases where the timing did not match what was scheduled. Representative review excerpt: "I was scheduled for tech to come between 3-7 and moved all my afternoon plans to the morning and then they showed up 2 hours early without calling and I..."

Workmanship & site care

Workmanship7.8/10

Workmanship is one of the strongest areas in the review set. Reviewers frequently describe professional crews, careful installation, and good cleanup, though a smaller group reports leaks, debris, or follow-up repair concerns.Solar.com's composite of published customer feedback, not a customer quote

Professional installation quality. Many reviewers describe the crew as knowledgeable and professional, with installations that were completed cleanly and to expectations. Representative review excerpt: "Great product, Great price, Excellent installation, Knowledgeable and professional installer, Excellent communications with Jayson in quoting, updating and purchasing."

Attention to finish and appearance. Some customers highlight extra care in the install, including visually matching piping and completing the work neatly. Representative review excerpt: "They painted all the pipes to match the roof and house, as well as any new plumbing they installed."

Leak and cleanup complaints. Complaint reviews mention post-install leaks, debris from roof work, and other site-care issues that needed attention after the job was done. Representative review excerpt: "Their solar water heating system started leaking less than a year after installation."

Long-term support & performance

Long-Term Support6.8/10

Post-install support trends positive overall, but this category has a meaningful set of complaints. Reviewers often mention helpful warranty service and solid system performance, while others report repair delays, service charges, or disputes over warranty handling.Solar.com's composite of published customer feedback, not a customer quote

Warranty repairs handled well. Several reviewers say warranty-related repairs were taken care of and that service follow-up was helpful after installation. Representative review excerpt: "They have taken good care of any warranty repairs."

System performance reported as strong. Some customers say the system performed as expected and that service visits resolved issues promptly when needed. Representative review excerpt: "Celestial’s pleasant representatives were thorough and had everything working perfectly in no time at all."

Service and warranty frustrations. Complaint reviews describe disputes over warranty coverage, repair timing, and service charges that felt high for the work performed. Representative review excerpt: "Today, we paid $240 for a service call and $135 for a $15 plumbing part."

Bottom line: Celestial Solar & Water Systems holds an overall Solar.com installer score of 7.7/10 based on 778 substantive reviews. The review profile is strongest on workmanship, communication, and timeline reliability, while price and financing transparency is the clearest weak spot, with complaints about added charges, deposits, and refund-related disputes.

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.
