Diamond Solar Solutions reviews

Tony S. had Diamond Solar install a residential solar system on his home about three years ago. Recently he discovered an alert in the system monitoring app and rang up owner Barak; within a couple of hours Barak had a technician at the house. They diagnosed the issue and fixed it in roughly an hour, leaving the system back to normal. What stuck with him was the owner’s personal involvement and same-day response — after years of trouble-free operation, a quick on-site visit and one-hour repair demonstrated that the company truly stands behind its work and only recommends what’s needed.

Andy leaned on Rob to choose the right solar system and ended up beyond happy with the result. He found Rob’s hands-on guidance made the decision easy, and Brad and Josh showed up as friendly, helpful teammates during the process. Pricing landed competitively, and the combination of personal attention plus fair cost left him confident in the purchase.

Matthew hired Diamond Solar Solutions for his new-construction home and ended up with a 7 kW solar array, two Tesla batteries and a Span subpanel. He watched Barak and his crew carry the project from planning to final hookup, handling layout, permits and installation with steady, hands-on attention. The team moved through the job cleanly and efficiently, turning what could have been disruptive work into an almost painless process. The finished setup—panels, battery storage and the Span subpanel—arrived on schedule and integrated smoothly into the new build. He won’t look to another solar installer; the thing that stuck with him most was the crew’s seamless execution from design through completion.

Robert hired Diamond Solar to outfit his home with panels and two Tesla batteries. From the first call through project closeout he found the crew professional and down-to-earth, and the install finished about a month ago. In that first month the system delivered roughly 97–98% self-sufficiency for most days, a level of performance that stood out. He trusted the same crew—Barak’s team—enough to bring them back to install batteries and add expansion panels at his kids’ house as well. The detail that sticks: near-total energy independence within weeks, and enough confidence in the crew to have them do a second family install.

Andy H. contracted the company to install a 16-panel Hyundai solar array plus a Powerwall 3 on his home and ended up with a system that’s been working very well. He found the price fair and appreciated the hands-on attention from Josh and Brad, who managed the job and took care of the details. The combination of a smoothly operating installation and personal service from those two crew members is what made the experience memorable for him.

Rick W. had waited several months after installation to test the results, and the story starts with a long-standing relationship: years earlier he met Barak when Barak was the lead installer on his original array. He trusted Barak’s technical depth and character from that first job, and when Barak struck out on his own with Diamond Solar Rick decided to follow him. In April 2025 they expanded the array and added batteries, and Rick watched the whole process closely. Barak walked into the project with up-to-date knowledge and an attention to detail that kept exceeding expectations. Pricing landed in a competitive range, and the crew mirrored Barak’s customer-first approach: punctual, professional, polite, treating the property as if it were their own, cleaning up thoroughly each day and setting clear expectations for the next visit. Rick called often—he’s a detail-oriented customer—and Barak always picked up or returned calls promptly, never making him feel like a burden. The expansion arrived on time and within budget. After months of number-crunching, Rick found the system’s performance matched Barak’s projections exactly. That fit between promise and measured outcome is what,

Rick waited several months after enlarging his solar array and adding batteries to pore over the performance data, and he discovered the system produced exactly what Barak had promised. He first met Barak years earlier when Barak worked as a lead installer for a different company, and after that initial project Rick trusted Barak’s expertise and character so much that he told him he’d follow him if he ever started his own firm. When Rick decided in April 2025 to expand capacity and add storage, he called Barak at his new company, Diamond Solar, and found the same deep technical knowledge and patient, accessible approach he remembered. Barak answered every question, picked up the phone or returned calls promptly, and stood by his estimates; Rick called multiple times during the job and never felt like a nuisance. The Diamond Solar crew arrived on time, treated the property as if it were their own, cleaned up at the end of each day, and set clear expectations for the next visit. Pricing proved competitive, the expansion arrived on schedule and within budget, and after months of tallying kilowatt-hours the actual output matched Barak’s projections. What lingered for Rick wasn’t just a

Eric discovered his rooftop solar array had shut down only to learn the original installer had gone out of business, leaving him with an orphaned system. After an industry contact recommended Diamond, he called Barak on Monday; Barak lined up foreman Brad to come out by Wednesday and quoted the company’s hourly rate over the phone. Brad arrived professionally, went straight to work diagnosing the issue, found a melted connection, repaired it, and inspected the remaining wires and connections. The crew kept communication clear and professional throughout. The detail that stuck with him: a transparent, speedy response that traced the outage to a single melted connector and fixed it within days.

John L. called Diamond Solar Solutions after the company that installed his rooftop system couldn't pin down a persistent problem. Diamond sent a tech named Brad, who diagnosed and resolved the issue in short order, leaving the system working as intended. He walked away relieved that a second opinion fixed what the original installer couldn't and wished Diamond had handled the installation from the start — the quick, decisive service from Brad is the detail that stuck with him.
