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

How does Sky Power 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 Sky Power 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.

Sky Power Systems 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 Integrity7.2/10

Reviewers generally describe the sales process as clear and informative, with several saying options, pricing, and system design were explained up front. The main complaints are about over-selling, missing details in the written contract, and a few experiences where expectations around follow-up or scope did not match what was later delivered.Solar.com's composite of published customer feedback, not a customer quote

Clear, informed proposals. Several reviewers say the sales team explained options clearly and helped design systems that fit their needs. Representative review excerpt: "Janice was very helpful in explaining all of my options and helping design a system that was right for me."

Up-front expectations. Some reviewers report that the proposal and pricing were fully explained before they signed. These comments suggest many customers felt they understood the package they were buying. Representative review excerpt: "Everything was fully explained up-front."

Contract and sales concerns. A smaller set of reviewers caution that important details should be in writing and describe sales follow-up as less reliable after the sale. These comments point to occasional concerns about contract clarity and sales pressure. Representative review excerpt: "However, if you decide to use them for your solar installation be very, very careful that everything you are told is explicitly contained in the written contract that you sign."

Price & financing transparency

Price Transparency6.5/10

Reviewers are divided on pricing and financing transparency. Many describe the company as competitively priced and responsive, while complaints focus on misleading advertised pricing, verbal quotes not matching final bills, and repayment or financing questions that were not resolved quickly.Solar.com's composite of published customer feedback, not a customer quote

Pricing pricing for many customers. Several reviewers say they received a better price or a stronger overall package than they expected. These comments frequently pair pricing with a positive view of the equipment and warranties offered. Representative review excerpt: "I had compared two companies and went with sky power, which I felt had a better price, solar panel product and overall package of warranties."

Clear value in some bids. These accounts suggest many customers felt the pricing made sense for the system they chose. Representative review excerpt: "SkyPower is local, courteous, prompt, professional, and had a better price for the panels I wanted than their competition."

Pricing and refund disputes. A smaller group of reviewers report concerns about misleading advertised prices, verbal quotes that changed, and unanswered questions about reimbursements or loan payments. These comments make price and financing the most mixed area in the review set. Representative review excerpt: "When the service bill arrived it was $40 higher then quoted verbally."

Communication & coordination

Communication6.7/10

Reviewers often praise the team for quick replies, helpful explanations, and hands-on coordination during the project. Complaints are centered on missed follow-through after installation, unanswered refund requests, and some warranty or service contacts that did not lead to timely help.Solar.com's composite of published customer feedback, not a customer quote

Responsive project support. Many reviewers say emails and calls were answered quickly and that staff helped translate utility or system details into plain language. This suggests coordination was often a strength during the active project phase. Representative review excerpt: "Sky Power has responded quickly to every email I've sent and translated "PG&E-speak" for me."

Helpful one-on-one guidance. Some customers describe technicians and staff as patient, informative, and willing to walk through system questions. These reviews reflect strong personal support when customers needed clarification. Representative review excerpt: "I contacted Skypower and was connected to a great technician, Telmo, who spoke to me on the phone a few times to help me understand how the system works and..."

Post-install follow-through gaps. A smaller set of reviewers say follow-up became difficult after the sale, especially around refunds, warranty questions, or post-installation documentation. These comments point to occasional breakdowns in ownership once the project was completed. Representative review excerpt: "I have had email contact with the CEO, Bob Winn, but he has not responded to my request for this refund."

Timeline reliability

Timeline Reliability7.3/10

Reviewers mostly describe the company as reliable on scheduling, installation timing, and getting systems turned on. A few comments note delays or slower-than-expected starts, but the overall pattern is that projects still moved through to completion without major disruption.Solar.com's composite of published customer feedback, not a customer quote

On-time installation experience. Several reviewers say crews arrived on time, worked as expected, and kept the project moving according to plan. These accounts point to solid schedule discipline during installation. Representative review excerpt: "Installation was done by a crew who was easy to schedule, showed up on time, took as long as predicted, explained everything along the way, and even asked whether to..."

Smooth path to activation. Some customers report that the project finished cleanly and they were brought onto the grid without major issues. Others say the crew completed the job ahead of schedule. Representative review excerpt: "Their crew was very professional and completed the project ahead of schedule."

Occasional delays. A few reviewers mention that the company was busy or that there was some delay before installation. These comments are present but limited relative to the more common on-time reports. Representative review excerpt: "They were so busy it took a little while to come do install but was pleased with the professionalism of the install staff as well."

Workmanship & site care

Workmanship7.8/10

Reviewers overwhelmingly describe the installation crews as professional, careful, and efficient. Praise commonly covers clean work, solid execution, and smooth completion, while the smaller set of complaints focuses on follow-up items and occasional installation-related tasks that required extra calls.Solar.com's composite of published customer feedback, not a customer quote

Professional crews. Many reviewers say the crew was professional, easy to work with, and finished the installation without problems. These comments consistently frame the on-site experience as strong. Representative review excerpt: "The installation went without a hitch."

Careful, efficient install work. Customers also mention crews that showed up on time, explained the process, and completed work as predicted. This suggests the company’s installation execution is a frequent bright spot. Representative review excerpt: "Installation was done by a crew who was easy to schedule, showed up on time, took as long as predicted, explained everything along the way, and even asked whether to..."

Some follow-up installation items. A few reviewers say they had to make repeated calls to get certain installation details completed or corrected. These comments are limited, but they show that site care was not perfect in every case. Representative review excerpt: "I had to call numerous times to get things installed like electrical grounding, piping straps, remote control, operating instructions, etc."

Long-term support & performance

Long-Term Support7.6/10

Reviewers generally report good system outcomes after installation, including successful repairs, warranty help, and support that got systems back online. The main complaints involve slower service follow-up, inverter or production problems, and a few cases where appointments did not happen as scheduled.Solar.com's composite of published customer feedback, not a customer quote

Warranty and repair help. Several reviewers say the team was able to help restore systems to working order or handle warranty-related parts quickly. These comments suggest support after turn-on can be effective when service is available. Representative review excerpt: "My solar system is not originally installed by Sky Power, but they are able to service my system back to operational!"

Helpful performance guidance. Some customers describe the company as providing useful guidance on system choice, performance tradeoffs, and warranty considerations. That support appears to have helped them feel confident about the setup they chose. Representative review excerpt: "For example, SunPower brand panels would have been about 3% more efficient for me, but would have cost more than 5% more and had a shorter warranty, so I ended..."

Service gaps after installation. A smaller group of reviewers report delayed service visits, monitoring issues, or systems that were still not operating as expected after multiple loan payments. These comments indicate that long-term support is an area with some unresolved complaints. Representative review excerpt: "I already made 3 loan payments the 4th one coming in the next few days and my solar is still not working."

Bottom line: Sky Power Systems earns a mostly positive review profile, with the strongest marks in workmanship, long-term support, and timeline reliability. The most notable cautions involve pricing transparency, post-sale communication, and occasional gaps in follow-through after installation. Complaints are present in every category, but they are generally outweighed by positive reviews in the aggregate score.

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.
