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

How does Sunko Solar 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 Sunko Solar 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.

Sunko Solar 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 Integrity7.2/10

Reviewers describe SUNKO SOLAR’s sales process as clear and straightforward, with strong praise for transparency and a low-pressure approach. The available reviews do not show complaint patterns in this category, and comments often focus on proposal clarity, realistic expectations, and helpful guidance through the decision process.Solar.com's composite of published customer feedback, not a customer quote

Transparent, easy-to-understand proposals. Reviewers say the sales experience felt clear and easy to follow, with a transparent approach that helped them feel comfortable moving forward. Representative review excerpt: "after shopping around with vultures for months this guy was the easiest and most transparent."

Helpful guidance during the decision stage. Some reviewers describe the team as personable and supportive, noting that the guidance helped them feel good about choosing solar. Representative review excerpt: "Super team and Marco has a very awesome personality that made me feel good about doing solar."

Practical system design and expectations. Reviewers also mention that the proposals seemed grounded in how the roof and system would actually be used, rather than feeling oversold. Representative review excerpt: "Actually utilizes your roof and your panels rather than use and abuse your roof to sell power back to the grid and hold you hostage to the leasing company."

Price & financing transparency

Price Transparency6.8/10

Feedback on price and financing is limited but positive, with reviewers calling the process straightforward and the pricing fair. There are not enough reviews here to establish broader pricing patterns, but the available comments do not point to surprise-cost concerns.Solar.com's composite of published customer feedback, not a customer quote

Simple pricing experience. Reviewers describe the process as efficient and say the pricing felt strong for what was offered. Representative review excerpt: "Simple and efficient process and amazing price!"

Fair package value. One reviewer says the service package and follow-through were a good value and notes the price felt fair. Representative review excerpt: "The service package and follow thorough by far is the best we could find in the LA market with a fair price."

Communication & coordination

Communication7.2/10

Most reviews describe responsive, hands-on communication, including direct help with questions and coordination issues after the sale. A small amount of negative feedback appears in this area, so the overall picture is strong but not perfect.Solar.com's composite of published customer feedback, not a customer quote

Responsive, personal communication. Reviewers commonly say the team stayed responsive throughout the process and made the experience feel personal and supported. Representative review excerpt: "The personal touch and responsiveness made it an easy decision and it stayed the whole way through the process."

Hands-on help with complications. Several comments describe the team taking the lead when issues came up and working directly with the customer to keep the project moving. Representative review excerpt: "Even afterwards when we had complications with the city, Marco made sure to take the lead on the issue and help us make sure that our solar was connected."

One coordination complaint. A minority of feedback reports trouble getting the installation approved because the reviewer believed an application was not filed correctly, which points to a handoff or coordination breakdown in that case. Representative review excerpt: "I have had nothing but trouble in getting the solar installation approved by SCE due to the fact that this company not only failed to file an application with Southern..."

Timeline reliability

Timeline Reliability6.8/10

Timing feedback is mostly favorable, with reviewers saying work moved forward promptly and finished faster than expected. There is also one complaint tied to approval and activation, so timeline performance looks generally good but with a meaningful exception.Solar.com's composite of published customer feedback, not a customer quote

Faster-than-expected completion. Reviewers say questions were answered promptly and the work was completed and signed off sooner than they expected. Representative review excerpt: "Any questions were responded promptly and he completed the work, signed off, faster than I had anticipated."

Help pushing projects through approvals. Some customers report that the team helped manage city-related complications and kept the connection process moving. Representative review excerpt: "Even afterwards when we had complications with the city, Marco made sure to take the lead on the issue and help us make sure that our solar was connected."

Approval delay complaint. One reviewer reports serious trouble with utility approval and says the project stalled at the filing stage, which suggests a schedule-and-permitting issue in that case. Representative review excerpt: "I have had nothing but trouble in getting the solar installation approved by SCE due to the fact that this company not only failed to file an application with Southern..."

Workmanship & site care

Workmanship7.0/10

The workmanship feedback is limited but positive, with reviewers expressing confidence in the crew and no direct complaints about cleanup or damage in the available set. Because the sample is small, this section reads as a cautious positive rather than a broad pattern.Solar.com's composite of published customer feedback, not a customer quote

Professional crew impression. Reviewers describe the team positively and say the experience of having the crew on site felt reassuring. Representative review excerpt: "Super team and Marco has a very awesome personality that made me feel good about doing solar."

Installation experience felt solid. The available feedback points to a straightforward installation experience, without reported site-care problems in the evidence set. Representative review excerpt: "We've banked credits with LADWP for several months and it's more than keeping up through LA summer even with ACs running and electric cars charging."

Long-term support & performance

Long-Term Support7.0/10

Post-install feedback is positive, with reviewers saying the system performed well after activation and that support continued when issues came up. The sample is small, so this reads as encouraging evidence rather than a full long-term track record.Solar.com's composite of published customer feedback, not a customer quote

Strong early system performance. Reviewers say the system has been keeping up with usage after installation, including periods of heavier demand. Representative review excerpt: "We've banked credits with LADWP for several months and it's more than keeping up through LA summer even with ACs running and electric cars charging."

Persistent support after turn-on. One reviewer says the team continued to help diagnose a problem and work through customer-service issues after installation. Representative review excerpt: "Marco and his worker came to my house at least 3 times to diagnose my system and basically fight tooth and nail over the phone with customer service and to..."

Bottom line: SUNKO SOLAR’s review profile is broadly positive, with the strongest signals coming from sales clarity, responsiveness, and general post-sale support. The main caution is timeline-related: most reviews are favorable, but there is one notable complaint about approval and activation progress.

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.
