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

How does Solargraham 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 Solargraham 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.

Solargraham 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 Integrity7.9/10

Reviewers overwhelmingly describe the sales experience as clear, honest, and low-pressure. The feedback centers on straightforward conversations, professional follow-through, and proposals that matched expectations rather than feeling pushy or inflated.Solar.com's composite of published customer feedback, not a customer quote

Honest, professional sales conversations. Reviewers say the initial conversations felt genuine and professional, with a tone that built trust quickly. Several describe feeling respected rather than rushed. Representative review excerpt: "I called at least 20 solar companies before I spoke to Greg and I immediately knew how honest and professional he was the minute I talked to him!!!"

No pressure to buy extras. Reviewers report that they were not pushed to add equipment or sign immediately. That low-pressure approach comes through as a recurring strength in the sales process. Representative review excerpt: "Also Greg did not try to upsell extra equipment or pressure me to sign a contract immediately."

Clear recommendation from referral sources. Some reviewers say they were pointed to SolarGraham for the company’s one-on-one service and felt comfortable proceeding after speaking with Greg. The praise focuses on clarity and a straightforward proposal process. Representative review excerpt: "I asked the broker who he recommended and he said if I was ok with a smaller company he'd recommend SolarGraham, as their 1 on 1 service is great, Greg..."

Price & financing transparency

Price Transparency7.2/10

Most reviewers describe pricing and financing as transparent and manageable, especially when the financing process was explained clearly. A small number of reviews mention price concerns, so this category is positive overall but not spotless.Solar.com's composite of published customer feedback, not a customer quote

Financing process felt easy. Reviewers say the financing side was handled professionally and made the purchase process simpler. The comments suggest the paperwork and lender coordination were presented clearly. Representative review excerpt: "When it came to the official purchasing process, SolarGraham provided financing with a partnered Credit Union, who were also very professional, especially Tadey made life super easy."

Price and value described positively. Some reviewers describe the pricing as fair or favorable for the work completed. These comments focus on perceived value and a straightforward transaction. Representative review excerpt: "Greg's work was flawless, his professional mannerism and expertise with solar are unparalleled, and his price for the fix was incomparable to what other local businesses probably would have charged..."

A few price-related complaints. A small number of reviews raise concerns tied to price or timing around payments and incentives. Those mentions are limited, but they prevent this from reading as completely clean. Representative review excerpt: "Solar Graham is a company that I would use again and would recommend to anyone that is in need of solar company and if one is looking to having solar..."

Communication & coordination

Communication8.2/10

Reviewers consistently describe strong communication throughout the project. They mention timely updates, responsive handoffs, and a willingness to explain work as it progressed.Solar.com's composite of published customer feedback, not a customer quote

Responsive and easy to reach. Reviewers say the team stayed communicative and was easy to contact during the job. Texting and direct updates are mentioned as part of the customer experience. Representative review excerpt: "Able to communicate with technician through texting."

Clear updates during the work. Some reviewers report that the process was explained step by step, with the technician describing what he was seeing as he worked. That detail-oriented communication is a recurring theme. Representative review excerpt: "Instead of jumping straight to replacing equipment, he methodically worked through the diagnostics and explained what he was seeing along the way."

Respectful customer handling. Reviewers describe feeling heard and not rushed during conversations. The feedback suggests a cooperative style that helped projects move smoothly. Representative review excerpt: "He never once made me feel like I was bothering him, and the conversations felt genuine and human -- which is something you don't always get when dealing with contractors."

Timeline reliability

Timeline Reliability7.6/10

Reviewers generally say scheduling and arrival timing were handled reliably. The main pattern is steady communication around appointments and coordination, with no broad pattern of missed commitments in the corpus.Solar.com's composite of published customer feedback, not a customer quote

On-time appointments. Reviewers say appointments were scheduled in a timely manner and the technician showed up as expected. That reliability is a common positive thread in the timeline feedback. Representative review excerpt: "Was able to schedule in a timely manner and he showed up on time and communicated every bit of the way."

Stays in contact around scheduling. Some reviewers mention constant communication to fit the job into a busy schedule. This suggests active coordination when timing needed to be adjusted. Representative review excerpt: "He was in constant communication to fit us in his busy schedule ( all the rain we had)."

Willing to keep service moving. A few reviewers note that the company was willing to come out and handle service work when many others would not. Those comments frame the timeline experience as responsive rather than stalled. Representative review excerpt: "After calling almost every available solar company in the area, only a small handful were willing to come out and service a solar system that they themselves had not installed."

Workmanship & site care

Workmanship8.8/10

This is the strongest category in the review set. Reviewers repeatedly describe careful installation, professional crews, good cleanup, and attention to detail on the roof and around the property.Solar.com's composite of published customer feedback, not a customer quote

Careful, efficient installation. Reviewers describe the installation work as efficient and technically solid. Several mention that the crew handled the job carefully while solving problems on site. Representative review excerpt: "Not only did he install the new panel efficiently, but he also diagnosed an additional issue that had been completely missed during our initial diagnostic test by another provider."

Attention to roof details. Some reviewers say the technician noticed roof issues like cracked shingles and addressed them while working. That kind of observation is part of the positive workmanship pattern. Representative review excerpt: "While he was up on the roof working on the system, he noticed a few cracked shingles and took the time to point them out and fix them while he..."

Cleanup and property respect. Reviewers also mention debris cleanup and taking care around plants and other property items. The feedback suggests a tidy job site and respectful onsite behavior. Representative review excerpt: "He did everything I asked without complaining, from moving some potted plants out of the way to cleaning up every tiny piece of debris that fell to the ground off..."

Long-term support & performance

Long-Term Support8.1/10

Reviewers generally describe strong post-install support, including follow-up troubleshooting and monitoring help. The one complaint is limited, but the broader pattern is of responsive service after the system was already operating.Solar.com's composite of published customer feedback, not a customer quote

Problem-solving after install. Reviewers say issues were fully resolved and the system was left working properly before the job was considered done. That follow-through is a major positive in the post-install feedback. Representative review excerpt: "Greg went above and beyond to fully resolve the problem and made sure our entire system was working at 100% before he left."

Support for equipment failures. Some reviewers mention help replacing failed components and describe the response as knowledgeable and fast. These comments point to practical warranty or service support after turn-on. Representative review excerpt: "Greg was beyond incredible with his knowledge, speed, and overall customer service replacing my power inverter that failed."

Monitoring and follow-up communication. Reviewers also note texts when monitoring goes down because of customer-side issues, which suggests ongoing attention after installation. That kind of follow-up support appears in multiple reviews. Representative review excerpt: "We’ve received texts when our monitoring system goes down due to our own wifi issues."

Bottom line: Across 73 substantive reviews, SolarGraham earns strong marks for workmanship, communication, and sales professionalism, with especially high praise for installation quality and site care. Price transparency, timeline reliability, and post-install support are still viewed positively overall, though a small number of reviews raise limited concerns around pricing or service timing.

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.
