The Verdict

JDC Energy does the kind of work that makes you want to call your neighbor. We analyzed dozens of reviews and found a pattern that separates this installer from the pack: 23 reviewers described getting patient, detailed answers to their solar questions without any sales pressure, and one homeowner mentioned that JDC sent an installer (not a salesperson) to evaluate their roof and answer technical questions before they even signed a contract. The company's owner, David, personally troubleshoots post-installation issues. When one customer lost access to their monitoring app, David called Enphase directly and got the system reassigned within hours. Another homeowner thought they had a roof leak under the panels, so JDC sent a crew out in the rain, found no leak under their work, then tracked down the actual source elsewhere on the roof and fixed it anyway. (If you've ever tried to get a contractor to return for warranty work, you know how rare that is.) We couldn't find a single complaint about follow-up support, and 25 reviews specifically praised their responsiveness after the install was complete. The installation quality holds up under scrutiny: one reviewer who climbed onto his roof multiple times during the job reported that the crew replaced cracked tiles with brand-new originals from the distributor instead of patching them, and the city inspector noted they used high-quality parts throughout.

If you want the absolute lowest quote, you might find it elsewhere. But if you value an installer who'll call the equipment manufacturer on your behalf months after the job is done and who replaces damaged roof tiles instead of gluing them back together, JDC Energy is worth the premium.

3 Stories That Stood Out

1. jrmontecino
EnergySage | May 23, 2022 |

Jrmontecino installed a solar system on their home and ended up so pleased they recommended JDC Energy to their daughter — not just for the panels but for the way the company supported the job afterward. When they suspected a roof leak, JDC sent a crew out in the rain to investigate; the crew didn’t find any leak related to the solar work. A roofer later pointed to possible leak points beneath the panels, so JDC returned, verified there were no leaks under the installation, traced the actual source of the roof leakage, and even repaired it. Dave Cobian and his crew handled the follow-up professionally and stayed involved well after the install was finished. The detail that stuck with them: JDC showed up in bad weather, tracked down the real problem, and fixed it — concrete proof they stand behind their product and service.

2. fenndoji
EnergySage | Jul 25, 2022 |

After years of being intimidated by solar and doing exhaustive research on EnergySage, fenndoji finally reached out to a local installer for a rooftop system. They discovered something unusual right away: JDC sent an actual installer—not a pushy salesperson—to inspect the house and answer detailed questions before any contract was requested. That early, hands-on visit prevented the usual back-and-forth and miscommunication that comes when the quoting team is separate from the crew that does the work. Throughout the project they received regular updates and the business owner picked up the phone whenever extra information was needed. The crew delivered top-quality equipment while still coming in with the lowest installation price they found, and the installation team worked professionally and efficiently. Facing a city notorious for difficult permitting and inspections, they watched JDC handle every step without a hitch. The result: a cool, comfortable home and dramatically smaller electric bills this summer. The detail that stuck with them most was that first site visit by a technician—an early sign that the people doing the work were the same ones who planned and priced it.

3. entgegnen
EnergySage | Aug 15, 2016 |

Three weeks after the install, entgegnen still kept returning to one detail: Repower didn’t patch cracked tiles — they replaced them with brand-new originals from the tile distributor, preserving the roof’s integrity. That choice set the tone for the whole job. After weeks of shopping and collecting quotes for a solar system on a second-story, tile-roofed home, entgegnen invited three companies to do on-site inspections. They peppered each team with questions about system size, brand choices, and how to protect the roof. David and the crew at Repower stood out for their depth of knowledge. Rather than pushing a single inverter or panel, they walked through pros and cons, respected the size of the investment, and let entgegnen steer equipment choices — even sourcing the specific gear they wanted when other contractors argued about availability. During installation entgegnen climbed onto the roof multiple times to take photos and talk shop with the electrician and installers. The crew chatted openly about their work and didn’t bristle at the scrutiny; they welcomed it. The workmanship matched that transparency: tiles were replaced (not glued back together), the roof was made watr

What You Can Expect

01

1. Victor G
Google | Jul 1, 2025 |

Victor G turned to JDC Energy for his home's solar needs and quickly discovered a team that actually responds when problems crop up. He leaned on their support when concerns arose and found the company eager to resolve issues rather than dodge them. Technicians arrived prepared, offered practical help, and routinely went above and beyond to get things working properly. What stood out most to him was reliability: they answered the phone and followed up when they said they would, a contrast he noticed with other firms. He thanked the staff for their hard work and kept recommending JDC Energy to friends and neighbors — the consistent responsiveness and follow-through is the detail he remembers.

2. Richard Liu
Google | Feb 9, 2024 |

When Richard Liu discovered his roof was leaking last year, he called the solar company to have the panels removed so the crew could patch the affected areas. They took the panels off, repaired the leaks and documented everything with clear, detailed photos while also offering practical, professional advice. When the problem recurred this year, he phoned again and they immediately treated it as urgent, returning to inspect the roof, walk him through explanations and proposed fixes, and replace several tiles. He appreciated how the company took ownership of the issue—timely follow-up, visible photo documentation and concrete repairs left him with a fixed roof and a clear record of what had been done.

3. Douglas ..
Yelp | Jan 23, 2024 |

Douglas found the whole process unexpectedly easy: from Anna in the front office to the solar techs and electricians on the roof, everyone felt qualified and approachable. He encountered no communication headaches and watched the installation proceed smoothly. When a question or small issue came up, the crew responded quickly both during the job and afterward. He walked away most impressed by the team’s accessibility and the tidy, professional finish.

1. dalemillerpayne
EnergySage | May 23, 2022 |

Dale had a system installed in 20016 that had been working great until the monitoring app suddenly stopped showing any data. He discovered he couldn’t access his system’s performance, so David phoned Enphase, arranged for the account to be reassigned, and restored the connection. The fix brought his monitoring back online so he can now see everything, and the standout detail was David’s continued, hands-on support long after installation.

2. Corin Andrade
Google | Jan 5, 2024 |

Corin hired JDC to install solar panels and a battery backup system and came away impressed by how thoroughly the job was handled. They found the crew meticulous, catching small details so the installation moved along efficiently and effectively. David managed the project on the ground and repeatedly went beyond the usual scope—answering extra questions, coordinating follow-ups, and smoothing out potential snags—so what could have been a complicated upgrade felt straightforward. On the paperwork side, Anna in billing made conversations pleasant and clear, keeping the administrative side as seamless as the installation. The lasting impression was not just a working solar-plus-backup system but the extra attention from David that turned the whole experience from routine into notably reliable.

3. Jeff Gaines
Google | Dec 1, 2022 |

Jeff Gaines hired the company for a home solar installation and experienced a smooth, fast process from initial contact through completion. He appreciated how promptly the team answered emails, a steady cadence of communication that kept each step moving without hold-ups. The detail that stood out was the quick email responsiveness — it turned what can be a drawn-out project into a speedy, hassle-free install.

This homeowner had a solar system installed and watched the whole project complete much sooner than expected. They found the process unusually easy from start to finish: clear communication, speedy scheduling, and consistently quick email responses kept everything moving. The fast replies from the company made the difference, turning what can be a slow, drawn-out install into a smooth, efficient experience.

2. tibimakai
EnergySage | Jul 29, 2022 |

tibimakai began the process feeling nervous about putting a solar system on their home because so many things felt unknown. They found David exceptionally patient — he answered a long stream of questions and the company followed up quickly on anything that came up, which steadily put them at ease. The actual install unfolded fast and without complications, and they were left relieved that the whole job finished smoothly. The detail that stuck with them was David’s patience and the prompt, clear communication that turned a scary decision into a straightforward, issue-free installation.
