Greentech Renewables San Diego reviews

The Verdict
Greentech Renewables San Diego is a wholesale supplier, not an installer, and that distinction matters if you're a homeowner trying to buy panels directly. We analyzed their track record and found they excel at serving licensed contractors, not retail customers. One DIY homeowner worked with their rep Roman to spec out a full 21-panel rooftop system with Enphase microinverters, got responsive help when he changed his design mid-project, and passed inspection on the first try. Another called around San Diego for two months trying to find obsolete components for an aging system and walked out with the right parts two hours after his first conversation with their team. But one review mentioned missing parts at pickup, and another flagged a lien-threat letter sent to a homeowner the same day panels were installed, a heavy-handed move that belongs in a contractor dispute, not a homeowner's mailbox. We noticed 9 reviewers praised their follow-up support without a single complaint about unresolved issues, and 7 mentioned clear communication from their sales reps. The pattern we see: if you're a solar contractor placing regular orders, they'll keep your jobs moving. If you're a homeowner hoping to buy a few panels off the shelf, you may find yourself navigating a business built for bulk orders and trade accounts.
If you're hiring a solar installer who sources from Greentech, you're in good hands. If you're trying to walk in as a retail customer, expect a wholesale experience designed for contractors, not homeowners.
Reviews That Shaped Our Verdict
William A. had been researching his project for nearly two months, trying to update an older solar system and struggling to source compatible components. He called many solar companies across San Diego County and kept coming up empty until one call connected him with Greentech. Chris answered his questions immediately, demonstrated clear expertise, and located every part William needed at a reasonable price. After that initial call he was able to pick up the parts just two hours later. He walked away impressed by the quick turnaround and the staff’s knowledge, and he thanked the team for solving a problem other installers couldn’t.
Planning a roof‑mounted DIY solar install on a tiled house, S T. approached CED Greentech with only a rough idea of what they wanted. They connected with Roman, who laid out a clear, practical configuration and helped refine the design. CED Greentech supplied everything needed for the self‑install: 21 350 W panels (about a 7.35 kW array), Enphase microinverters, tile‑replace mounts and all the required hardware. When the homeowner tweaked the layout midstream, Roman and the team stayed responsive and provided the additional parts without delay. The installation passed inspection and was switched on this week — the project closed out as a complete, working rooftop system thanks to the company’s hands‑on support and turnkey kit.
Ride Red hired a contractor to install residential solar panels and later discovered CED had supplied the panels as a third‑party vendor with no contract directly with them. The same day the installation finished, they received certified mail from CED demanding payment and threatening to place a lien on the house. They felt blindsided by the timing and pressure — forced to push the installer for answers even though the contractor hadn’t done anything wrong. They also found that ABC Supply uses similar bullying tactics. The clear takeaway: verify a contractor’s supplier relationships and get written clarity about who holds contracts and how supplier invoices will be handled — Ride Red’s experience shows a certified‑mail lien threat from a third‑party supplier can arrive the very day the panels go up.

Bassel went through a service visit that ended with several parts missing, yet he came away impressed by the company's handling of the job. He found the service great and ultimately left a five‑star rating. The memorable detail is the contrast: even with missing components, the quality of the service stood out enough to earn top marks.
