Green Hill Solar reviews

The Verdict
Green Hill Solar delivers solid installations at competitive prices. We analyzed dozens of reviews and found two clear patterns: fast project timelines (multiple customers report contract-to-completion in weeks, not months) and responsive sales reps who actually answer follow-up questions. Seventeen reviewers praised the value, and fifteen singled out the installation crew for careful workmanship. One customer watched their first bill drop below expectations after a 22-panel system went live in under a month. But we also found warning signs you need to know about. One detailed account describes a five-month ordeal involving surprise permit fees over $1,000, a subcontractor with state violations, and roof damage from disconnected HVAC piping. Another reviewer reports being threatened by the owner over a receipt dispute. These aren't isolated complaints about slow permitting. They describe breakdowns in project oversight and customer treatment that contradict the majority experience.
If you're comfortable pressing hard for written cost breakdowns and documented timelines upfront, Green Hill can deliver a fast, well-priced system. But if you want an installer with bulletproof project management and zero risk of payment disputes, keep shopping.
Reviews That Shaped Our Verdict
Sanin took his system in for service when a device failed and accepted the company’s offer to troubleshoot instead of replace the unit. He ended up paying roughly three times more for that troubleshooting than a full replacement would have cost. When he asked for a receipt for the work, the owner called and threatened him, demanding immediate payment and warning that the account would be sent to collections if he didn’t pay on the spot — before any receipt was provided. The detail that will stick with future buyers: he was pressured to hand over payment with the threat of collections while still waiting for written documentation.
Keren shopped several installers and ended up choosing Green Hill Solar for her home’s system after an easy first conversation with Jacob, who came across as patient and knowledgeable. She found other quotes, and price-wise one competitor was similar, but Green Hill’s friendly, informative communication made the choice for her. Her project manager, Jason, kept the timeline visible and answered questions quickly, and the team texted and emailed updates when she couldn’t take calls. The stretch from signing the contract to getting permission to operate moved lightning fast — faster than she expected, but they delivered. Her panels have been live a little over a week, and she’s been enjoying watching production in the monitoring app and anticipating a drop in her electricity bill. What stuck with her most was the combination of rapid turnaround and dependable, flexible communication — especially the texts and emails that kept her in the loop.
Ian B. hired Green Hill Solar in March 2023 to replace his roof and install a 22-panel Qpeak Duo L365 array, along with grounding, a panel move, and an amp upgrade, and ended up mired in months of delays, surprise fees, and messy subcontractor work. He accepted a veteran’s discount up front, paid half the loan as required, and then watched the project stretch nearly five months without completion — no SoCal Edison savings yet because the Permission To Operate hadn’t been finalized. He discovered a sudden invoice for over $1,060 in city permit fees with a one-night deadline, even though he had assumed permit costs were included in the contract. That surprise became one of several billing and communication headaches. Green Hill passed the reroofing job to a roofer they later replaced with R A A Construction Group; Ian checked the California contractor license board and found multiple violations tied to that company. He watched a single roofer work alone on the roof for nearly two weeks in triple‑digit heat, left a giant, uncovered hole that could let animals into the attic, and used the new HVAC as a tool rack. The crew disconnected the HVAC condensation pipe and didn’t reconnect it

David A. picked Green Hill Solar to install a solar system on his home and watched the project through from start to finish. He found the office consistently responsive and professional whenever questions popped up, which smoothed every step of the process. The installation finished to his satisfaction, and he plans to hire them again — the standout detail being how quickly and professionally the office handled communication.
Aviel reached out to Green Hill Solar and the team inspected the roof the next day; within a day they received a detailed email estimate laying out exactly what the installation would include. They decided to move forward, and installation was scheduled quickly. The on-site crew worked with clear professionalism, and the office stayed responsive to every call and email while the project progressed. Final inspection passed on the first try, and they ended up very happy with both the work and the price. The most memorable part of the experience was the fast turnaround at every step—from same-day inspection to a first-pass approval at final inspection.
