The Verdict
SolarGraham is worth calling first. We analyzed dozens of reviews and found Greg personally handles sales, installation, and service, which means you get the same expert from quote to repair. After shopping multiple big-name companies, one homeowner signed with Greg the same day because he quoted 39 panels instead of the 27 to 29 others proposed, at a lower price, using newer equipment. We found 49 reviews praising the workmanship with zero complaints about sloppy conduit runs or roof damage. Greg color-matches wiring to stucco or tiles, repairs cracked roof tiles during install at no extra charge, and leaves sites clean enough that city inspectors compliment the work unprompted. He also fixes systems other installers abandoned. When one buyer discovered a prior company had left a corroded junction box that killed production, Greg troubleshot over the phone for free, then replaced and relocated the box in two hours for a fraction of what competitors quoted. (He even moved floor-to-ceiling garage cabinets mid-install to improve a sub-panel location, calling it part of the deal.) If you want someone who answers his own phone from the roof and monitors your system years later, the one-man-crew model delivers accountability the sales-rep-to-subcontractor pipeline can't match.
If you're comparing purely on the number of crews a company can deploy at once, a larger outfit may finish faster during peak season. But if you want the person who designed your system to be the one wiring your roof and fielding your call three years later when a panel underperforms, Greg's hands-on approach is the safer bet.
3 Stories That Stood Out
In April Tom S. shopped several five-star Yelp solar companies for a system at his retirement home in Hemet and only three bothered to respond. The first bidder showed up with outdated equipment and a high price, and seemed more interested in using the job for marketing. The second came across as knowledgeable and candid about being a salesman who’d learned by observation; his price was reasonable, but Tom held out for one more bid that afternoon. Gregg Graham arrived with the standout offer: newer technology, a lower price, and room for 39 panels — roughly 10–12 more panels than the other bids — with only a small additional cost. After Gregg reassured him about HOA issues, Tom signed the same day. Gregg acted as owner, salesperson, and lead installer, working with Tony and one other helper; he often installs by day and takes calls in the evening, so missed calls usually meant he was literally on a roof or in an attic. Gregg returned to measure the roof and inspect the panel box and attic, delivered plans in about a week, and Tom submitted them to the HOA. The HOA review stretched into late May: first a three-week wait and requested changes, a second three-week review that forced
Natty moved into a house already fitted with solar panels and quickly discovered the system wasn’t producing power — and that Southern California Edison had hit them with a surprise bill. The original installer had gone out of business, and after calling almost every local solar company, only a few would even consider servicing equipment they hadn’t installed. Greg from SolarGraham stepped in where others hesitated: he spent extensive time on the phone troubleshooting potential causes so Natty wouldn’t be charged for a needless visit. When the issue couldn’t be resolved remotely, Greg came out within a week. He and his technician uncovered a combusted, corroded junction box on the roof — a failure rooted in the original poor installation — and, within about two hours, removed the damaged part, installed a correct replacement, and relocated it to a safer spot so it would be sheltered from the elements. Throughout the visit Greg explained, step by step, how the components had failed and why the repair would prevent future problems. The work finished quickly, professionally, and for a price Natty found far lower than the alarming quotes they’d been given elsewhere. The visit left Natt
Graham L. shopped two national installers and two local companies before choosing Greg's crew for a home solar install. He found the big, Costco-affiliated option difficult to work with and another national bidder too wedded to its own equipment, while Greg spent time educating him on how to avoid overbuilding and even pointed out mistakes Graham had picked up from inflated marketing claims. During the design phase his many questions were met with patience, which eased his anxiety and built trust. Much of the work happened while he was out of town; Greg called with a practical improvement — moving the garage subpanel — and the team shifted floor-to-ceiling cabinets to make it fit. Tile repairs were handled as part of the job, too. The installation wrapped up around the turn of the year, and he now checks production on his smartphone, with output matching what Greg promised. The detail that stuck with him was the combination of straightforward cost-saving advice and the hands-on willingness to rearrange the garage so the system could be done right.

What You Can Expect
While researching a whole-home solar system, Rhonda G. followed a coworker’s recommendation to G&M Solar and quickly stopped looking. She found Greg to be an industry expert rather than a salesperson — he customized a system to meet their goals, patiently explained options in plain language, and steered them toward top-tier American-made panels for durability and performance. Greg walked them through competing bids, highlighting what his proposal included above and beyond the others, and bundled a warranty and post-installation service program that proved more comprehensive than the alternatives. He managed the entire process — design, plans, permits, approvals — and was on-site directing his skilled crew during an on-schedule installation that finished without issues. The finished system has produced enough power to cover all of the household’s electricity for several years, eliminating their monthly utility bill, and Greg still monitors production and checks mechanical performance. The detail that stuck with her most: a professionally executed, end-to-end project that now delivers zero electric cost and ongoing, hands-on follow-up from the installer.
Dee Dee H. decided it was finally time to remove a long-unused solar pool heater that had left heavy calcium stains across the roof tiles of her ranch-style home. She chased down roofers who pushed expensive tile replacement, roof-cleaning outfits that seemed unsure how to tackle the calcium, and solar companies that only knew how to unbolt panels — each either wanted to use harsh chemicals or charged more than she could justify. After one last Yelp search she found Greg, owner of Solargram, and everything clicked. Greg removed the panels, patched and sealed every hole left from twenty years of mounting hardware, and even glued and repaired a few broken tiles he found. He cleaned the thick calcium buildup using a pressure washer and only water, explaining that tile replacement and harsh chemicals weren’t necessary. He offered a clear plan, a fair price, and next-day availability during their first phone call, so she booked him. Greg spent five hours on the job: answering every question (she recorded parts of the work), moving potted plants, picking up every tiny piece of debris, and working methodically and patiently. The roof came away dramatically improved, and Dee Dee plans to聘]
Brandon was searching for someone to handle a residential solar installation and found Greg, who turned out to be exactly the kind of contractor he wanted. What stood out most was the pride Greg took in his work — paired with a friendly manner, solid knowledge, and straightforward honesty that showed up at every step. He watched that pride translate into a smooth installation process and clear answers to their questions. He ended up very happy he'd chosen Greg for the job; the image that stuck with him was how much care Greg put into the finished system.
Michael installed a 20-plus-panel solar system in 2020 and ended up with a contractor who kept tending to the system long after the install. He received ongoing, proactive service — texts whenever the monitoring went offline (often due to his own Wi‑Fi) and a phone call when one panel began underperforming. Greg stepped in personally and pushed to get that panel issue fixed, covering the work at no extra cost. The memorable takeaway: this company doesn’t disappear after installation — they monitor performance and pick up the phone to resolve problems, even years later.
Michelle needed her system’s inverter replaced and found that Graham responded promptly even while on vacation. She secured a quick appointment, and he arrived on time. He kept her informed at every stage and completed the inverter swap with professional care. The new inverter has been working well since the service. What stuck with her was his responsiveness during vacation and the steady communication throughout the job.
Joyce reached out to Greg at Solargraham after a rooftop system installed in 2022 never ran and left her with a $10,000 bill from Southern California Edison when the original installer abandoned the job and later went out of business. She found Greg unusually responsive and thorough: he visited the home, contacted the inverter manufacturer to restore monitoring, corrected the wiring faults, and got the array producing power. No other repair outfit even returned her calls, so the standout detail was his hands-on follow-through—working directly with the manufacturer and fixing the wiring—turning an abandoned, nonoperational system into a monitored, working one.
John Kim chose Greg at SolarGraham for a substantial home solar installation and found the entire experience surprisingly smooth. He discovered that Greg’s professionalism, reliability and plain-spoken honesty—plus a relaxed, approachable manner—kept decision points simple and the project moving without headaches. He trusted Greg through the big purchase, ended up with the installed system, and plans to tell friends and family about the company. The detail that lingers: Greg’s dependable, down-to-earth approach turned a potentially stressful investment into a low‑stress, straightforward process.
Ron needed a repair on his home solar system after a stretch of heavy rain and turned to Greg to handle it. Greg stayed in near-constant contact to slip the job into his busy schedule and kept him informed about any costs that would come up. He watched Greg’s crew arrive tidy and professional; they completed the repair in a single day and had the panels back online by evening. What he remembers most is the steady communication paired with the one-day turnaround—clear cost updates and a clean jobsite made the whole process straightforward.
Karen K. turned to Greg when her solar system needed repairs after a run of bad weather. He worked her into a packed schedule despite the rain, kept her regularly updated about any potential costs, and coordinated the job so the repair wrapped up in a single day. The panels were back online by evening, and his crew left the roof and yard neat and professional. What stayed with her was the steady communication through a hectic, rainy stretch and a quick, clean one-day fix.
