The Verdict
NRG Clean Power leaves us with serious concerns. We analyzed hundreds of reviews and found a company where experience quality depends entirely on which coordinator you draw. One customer paid their deposit in 2021 and a year later still had zero electrical work done, a rotted fascia board the roofer tried to hide, and a project manager who quit without anyone telling them. Another signed in November 2024 for a Powerwall, waited seven months for installation, then waited four more months with the system still not connected to the grid despite sending multiple emails that went unanswered. The positive stories do exist: 251 reviews praised workmanship quality, and coordinators like Shelley and Aracely earned repeat mentions for chasing down permit delays and proactively monitoring systems after service calls. But 116 reviews flagged value problems, and the delays aren't outliers. One reviewer noted NRG's remove-and-reinstall fees ran $4,200 compared to $2,200 at competing companies. We found this company either delivers a polished experience or leaves you chasing them for months, and you won't know which until you're already in.
If you need a company that will honor commitments and communicate proactively, look elsewhere. NRG may eventually complete your install, but reviews show too many customers paying upfront, waiting over a year, and still lacking a functional system.
3 Stories That Stood Out
Andrew G. contracted with NRG in August 2021 for a package job on his Berkeley Hills property: a bitumen roof replacement, a new 200‑amp electrical panel and a 9.1 kW solar array with LG batteries. Tony Roberts handled the sale and everything started with reasonable expectations — but a year later the project stalled, and the electrical work never moved forward. The roof replacement went ahead in October 2021 via an NRG subcontractor, but the workmanship fell short. Rotten fascia boards were left out of sight rather than replaced despite a change order that spelled out the exact linear feet to be fixed. Andrew had to push the roofer to return and finish the job, and even then the quality remained below standard; by July 2022 the roofer told him NRG still hadn’t paid for that work. Communication broke down across the rest of the project. The Southern California project manager quit early in the year without the homeowner being told, email replies stretched into weeks, and requests for phone or video meetings to agree milestones went unanswered. When NRG did respond — for example, by asking detailed questions — follow‑through rarely materialized. Electical clarity never arrived
Dan L signed a contract with NRG Clean Power in November 2024 for a Tesla Powerwall installation and then waited more than seven months before the equipment finally went up at the end of June 2025. Four months after that installation, the Powerwall still sits offline because it has not been connected to the **** smart network. He was repeatedly told the hold-up was permits; the fire safety permit cleared months ago, but no further steps followed and communications from the company stopped. Multiple emails to NRG Clean Power went unanswered, leaving him unable to use the system he paid for and growing increasingly frustrated by the lack of transparency and accountability. After investing a significant sum, he reached out to the BBB to get help securing the remaining network hookup and to push NRG Clean Power to finish the job they were contracted to do.
Kunal N. hired NRG to put solar on his house in November 2021 and took an unusually hands-on role in the system design—picking system size, panels and microinverters—and Zach, the sales rep, provided detailed answers to every question. The install itself unfolded smoothly over two days, including inspection, with project manager Ashley staying responsive and keeping him informed at every step. Two years later an Enphase gateway stopped reporting properly, so he submitted a support request; Shelley responded within a day and booked a tech visit three days out. After the service call Shelley monitored the system, noticed the data still looked wrong, and had the technician return to reinspect his work. She tracked the issue before and after the visits and followed up repeatedly until the monitoring was restored. What stuck with him was Shelley's hands-on follow-through—she didn’t just send someone out, she watched the results and made sure the problem was actually fixed.

What You Can Expect
After several years with a rooftop microinverter setup, Victor discovered a couple of the microinverters had failed and contacted NRG, the company that installed his system. Shelley took charge: she tracked down the Enphase replacement parts, kept him in the loop at every step, and as soon as the parts arrived she arranged a technician to come out quickly. The tech not only replaced the faulty microinverters but also took time to correct some minor wiring issues he found while on the roof. The whole warranty repair unfolded smoothly and without hassle — Victor ended up with working inverters and tidier wiring, and he remembers Shelley's proactive communication and the technician’s extra attention to detail.
Mike had solar panels installed and, three years later, discovered the system was still working perfectly. He ended up with a completely trouble-free setup that simply performs as intended and demands no effort from him. When NRG overlooked finalizing one city permit tied to a main-panel upgrade, he alerted the company and they moved quickly to fix it. Shelley Immken stepped in, worked directly with the city to finalize the permit and sorted any associated fees. The detail that sticks is the company's fast, hands-on follow-through—especially Shelley's handling of the permit—so the system kept running without interruption three years on.

Jeff had NRG install a residential solar system about three years ago, picking them mainly because their price beat the other bids. The installation hit a few snags, but the crew finished the job and he was ultimately satisfied with the result. For the first couple of years the array performed well, though one inverter glitched a few times; the system’s monitoring caught each problem immediately. Shelley at NRG stepped in every time, coordinating firmware updates with the manufacturer and getting the inverter back to normal. When that inverter finally failed a few weeks ago, Shelley moved quickly again — she ordered a replacement and arranged for an installer to swap it out right away. What stuck with him most was that post-sale responsiveness: after choosing on price, he discovered that NRG’s customer-support team reliably handles repairs and follow-up, including a fast parts replacement when the inverter died.
Victor had been with NRG for about four years and had sent several family members and friends their way after positive experiences. He recently discovered two microinverters on his system had failed and contacted the company; Shelley walked him through remote troubleshooting and asked him to wait 24–48 hours to see if anything changed. After the window closed, Shelley proactively checked back, diagnosed a hardware failure and told him a replacement had already been ordered — he never had to chase the issue. He appreciated that she monitored the system and arranged the repair automatically. He’s now waiting for the technician to install the replacement part and will update if anything else occurs. The standout detail from his long relationship with NRG is that customer service stays reliable and hands-on even years after installation.
Molly Rolig started off thrilled — the sales team impressed her and the financing group stepped in helpfully, so much so that she recommended the company to friends and family. Once the project moved to scheduling, however, she hit a wall: months passed with very little response and no confirmed install timeline. She pushed for answers and even escalated the issue to managers, but struggled to get meaningful updates. Now she fears the system won’t be installed by the end of the year, which could cost her thousands in a missed rebate. After a process that has stretched past a year, she feels beyond disappointed. The standout takeaway: excellent pre-sale service, but persistent scheduling failures left her facing a real financial loss tied to deadline-driven rebates.
Adriano has had an NRG solar system on his Bay-area home since 2021. When an inverter problem popped up recently, he watched Daniel Duncan and the support team patiently troubleshoot the issue remotely, guide him through a fix and even stay late to make sure the system came back online. He walked away impressed by the hands-on support and feels the aftercare proved NRG’s value. He calls them the best installer in the Bay because their pricing and responsiveness line up. He plans to keep working with NRG as he adds a battery backup and other green technologies to his house.
Loc Le signed a contract with NRG Clean Power in mid-to-late 2022 for a home solar installation in San Antonio. The sales team promised a 3–4 month install and 4–6 month activation, but the project went off the rails: the panels were physically mounted by a subcontractor in early 2023, and then everything stalled because permitting and paperwork kept getting rejected or closed for lack of response. He ended up with idle panels on his roof while permit applications bounced between the city, the utility, and NRG. At one point a subcontractor even called to threaten a lien on his house because NRG hadn’t paid them, and he had to intervene and push the subcontractor back to NRG’s project coordinator. Communication broke down repeatedly — he went through three coordinators, received inconsistent or no updates, and felt like he was managing the job himself. To make matters worse, he financed the system with a deferred payment window to avoid overlapping bills; that grace period expired and he wound up paying both his electric bill and loan payments while the system sat unused for years. After that long run of delays and frustration, NRG ultimately turned things around. They assigned anew
Jennifer M. waited more than a year for her $0 installation to be completed, and when the crew finally showed up she discovered the system was only half finished and the backup batteries were not connected correctly. She spent the next two months begging the installer to return and fix the wiring, but her sales rep and customer service fell silent. Now her loan is coming due while a key portion of the system sits incomplete and unusable.
