The Verdict

NexGen Construction is the solar installer you hire when you want someone who'll still pick up the phone six years later. We analyzed well over a hundred reviews and found zero complaints about their workmanship—79 people mentioned it, and all 79 were positive. One homeowner called Eric back to expand a system installed six years prior, and Eric walked him through a cost-benefit analysis so detailed he recommended against a battery because it would double the price for limited backup power. (Most installers would have quietly taken the extra revenue.) Another reviewer discovered during installation that a previous contractor had damaged a structural beam when swapping the electrical panel, and NexGen's crew fixed it without charging extra. The installation quality stands out: reviewers mention conduit runs hidden in the attic instead of snaking across the roof, panels aligned with no gaps, and wiring so clean that neighbors stop by to ask questions. We did find two reviews where customers reported unanswered calls for post-install panel issues, so responsiveness isn't flawless at scale. But 51 reviews praised their follow-up support with only 3 negatives, and one of those unanswered-call reviewers had originally given them a five-star review years earlier.

If you want the cheapest bid, keep shopping. But if you want an installer who treats your roof like his own and will still troubleshoot a failing panel four years later, NexGen is worth the premium.

3 Stories That Stood Out

1. Andrew Patti H.
Yelp | Mar 24, 2023 |

Andrew Patti H. began his solar search by vetting six local companies and discovered NexGen Construction stood out — their website clearly explained options and trade-offs, and an owner-produced video made the technical choices easy to follow. He invited Eric, the owner, to his house; Eric walked him through the different panel options NexGen installs, compared pros and cons side-by-side, and answered every question on the spot — something the other bidders couldn’t do without follow-up. Convinced during that visit, he committed to NexGen then and there. When installation day arrived, Zach and his crew showed up on time and worked professionally. Zach told him he treats every home like his own, and the workmanship proved it: the panels sit perfectly level with no gaps, all wiring was run through the attic so there are no pipes across the roof, and the upgraded electrical panel looks clean and finished. While opening the wall for the new panel, the crew discovered previous work had damaged a structural support and corrected it so the job was done properly. Neighbors have stopped by to ask about the installation because the neat, seamless appearance draws attention — that visible, no

2. Bryce L.
Yelp | Aug 5, 2021 |

Bryce L. first had NexGen and Eric install solar on his ranch-style home about six years ago. When he decided this year to add more panels and a battery backup, Eric patiently walked him through a complete cost–benefit analysis, laying out the trade-offs so he could make an informed choice. Once the contract was signed, the project unfolded smoothly: NexGen handled rebate qualification, coordinated with SCE, secured permits, completed the installation, ran system checks, and Eric personally conducted the follow-up inspection. Zack showed up as site foreman again, the second time Bryce has worked with him, and the crew kept the schedule on track. Pricing landed in a competitive range and the level of service stayed consistently high. The detail that stuck with him was how NexGen managed the paperwork and utility coordination end-to-end, so the technical upgrades arrived on time with minimal hassle.

3. Mike M.
Yelp | Jul 27, 2025 |

Mike had a residential solar system installed in 2018, and Eric and the crew left a strong impression with a tidy, competent installation that led him to enthusiastically recommend them to friends. Those friends also chose the company, but about a year ago they needed follow-up work and ran into problems getting help. More recently one of Mike’s panels stopped functioning; he has phoned repeatedly over the past month and gotten no answer. At this point he isn’t sure whether the company is still operating. What lingers is the contrast between an excellent installation day and the current silence when service is needed—he’s been left with a nonworking panel and unanswered calls.

2. Eliz E.
Yelp | Jan 29, 2021 |

Eliz E. had a solar system installed five years ago, and what stuck with her wasn’t just the equipment — it was the company’s follow-through. When a couple of issues popped up years later that ultimately proved unrelated to the panels, Eric still showed up and helped track down the cause. From the first meeting through years of support, the team remained responsive and steady, which gave her real confidence in the long-term investment. The detail that lingered for her: a technician returning well after installation to troubleshoot problems personally — that level of follow-up made the difference.

3. B. M.
Yelp | Dec 11, 2020 |

B. M. had a new roof and a complete solar system put on their home about two years ago, and the standout fact is that everything has held up without a single problem. The crew left a neat, professional installation, and the roof and panels remain visually clean and fully operational the same way they were at handover. Eric, the owner, came across as approachable and punctual throughout the process, which made scheduling and communication easy. Because of that reliability and the owner's accessibility, B. M. has continued to refer neighbors and friends — the lasting performance plus an easy point of contact is the detail that sticks.

Yelp | Jul 27, 2025 |

Mike had a residential solar system installed in 2018, and Eric and the crew left a strong impression with a tidy, competent installation that led him to enthusiastically recommend them to friends. Those friends also chose the company, but about a year ago they needed follow-up work and ran into problems getting help. More recently one of Mike’s panels stopped functioning; he has phoned repeatedly over the past month and gotten no answer. At this point he isn’t sure whether the company is still operating. What lingers is the contrast between an excellent installation day and the current silence when service is needed—he’s been left with a nonworking panel and unanswered calls.

2. Michael S.
Yelp | Dec 23, 2019 |

Michael S. received an initial proposal from Eric and had it revised when they decided to proceed with a 2019 solar installation. He watched NexGen manage the project schedule closely, coordinating with both the roofing contractor and the fumigation company so the different crews didn’t get in each other’s way. The installation finished smoothly, and what stuck with him was that NexGen handled the tricky logistics between trades — especially the fumigation step — which kept the process hassle-free.

3. Johnny S.
Yelp | Jul 16, 2019 |

Johnny S. had solar panels put on his home in 2015. Four years later he noticed one panel was underperforming and reached out to Eric and Rich, who jumped on the problem right away. They methodically tested the inverter, ruled it out, and then replaced the faulty panel. He walked away impressed by the quick, hands-on troubleshooting and the straightforward replacement — the sort of service that felt unusually attentive and effective.

1. stephen
EnergySage | Oct 27, 2017 |

Stephen first started poking into solar in 2013 and, by chance, his very first contact was NexGen Construction. In June he connected with Eric, NexGen’s owner, who spent time walking him through the basics and answering questions even though Stephen wasn’t ready to commit. Over June and July he shopped installers, winnowed the field to three, and ultimately chose NexGen — not just for a competitive price but because the patient, educational sales process and the fact that NexGen is a full‑service company (not a crew that leans on temporary subs) built real confidence. Five years on, he reports that three friends followed his lead and also hired NexGen; all of them have been satisfied. The system itself has consistently outperformed the company’s estimates, typically by 5–20% each month, driving his electricity bills down to essentially nothing and delivering savings of more than $2,000 a year based on rates from five years ago — a return he likens to a tax‑free investment of better than 10% annually.

2. Fodog V.
Yelp | Aug 18, 2017 |

Fodog V. called NexGen Construction on a Monday to add a second solar system to his house, and by Wednesday the crew had finished the job. He ended up with five new panels equipped with micro-inverters and noticed immediate differences: the installed price per kW on this add-on is roughly half of what he paid 12 years ago, and the equipment itself is markedly better. NexGen moved quickly, coordinated the schedule, and left a tidy, professional installation. The detail that stuck with him was the sheer speed—a three-day turnaround from first call to finished install—paired with a much lower cost compared with his original system.

3. Antonio M.
Yelp | Oct 11, 2016 |

After many years of research, Antonio hired NexGen a few years ago to install solar panels on his home. He picked them because they offered what he judged to be the best warranty and the highest-quality equipment in the industry, and he hasn't regretted that choice. Although NexGen is a small, local company, he found their personal attention and customer service outperformed the big national players — they stayed attentive to his needs throughout. Years later he still values that combination of an industry-leading warranty and hands-on responsiveness; for buyers who prioritize strong guarantees and a local team that answers the phone, that was the detail that set NexGen apart.

Long-term Satisfaction

Long-term satisfaction for NexGen Construction drops to 4.6 ★ compared to early reviews. This is better than 52% of installers we looked at.
