The Verdict

Nation Energy Services (sometimes operating as Demand Construction) isn't worth the risk. We analyzed dozens of reviews and found a pattern of installations dragging on for a year or longer, with customers chasing the company for basic updates after paying. One homeowner signed in July 2024 and still had no working system a year later, bouncing between vague dates and missed appointments. Another waited 12 months from contract to permission-to-operate because the company submitted incorrect paperwork, forcing a second round of permitting, yet no one from Nation Energy reached out to explain or apologize. The post-installation support scored 1.6 out of 5, with 26 negative mentions against just 5 positive. Value scored even lower at 1.9, with 25 complaints about delays, unmet promises, and poor workmanship versus 7 positives. We found reports of used disconnect boxes installed on new systems, roof damage from improper flashing, and missing hardware that took months to replace. Communication after payment is nearly nonexistent, and several reviews mention unpaid subcontractors or independent sales reps still waiting for commissions long after install.

If you're comparing solar installers, this company's track record of year-long delays and vanishing support after payment makes it a poor choice. The risk of getting stuck in limbo, chasing updates while your panels sit dormant on the roof, is too high when more reliable installers exist.

Reviews That Shaped Our Verdict

Winnie L.
YelpJul 13, 2025

Winnie L. signed a contract with Demand Construction in July 2024 to have rooftop solar installed on her home. She spent the next year chasing vague promises: an October 2024 install slipped to January, then February, then March, with little to no updates unless she pushed for them. After a tense exchange she accepted a small discount and the crew finally completed the physical installation at the end of April 2025. Getting the system approved took another two months while she waited for government sign-off and PG&E permission to operate. When the company sent a final invoice and insisted they wouldn’t proceed until she paid, she felt uncomfortable handing over money before seeing the system actually working. After more back-and-forth they pledged to “commission” the array on July 8, so she paid the majority of the balance. July 8 came and went with no crew, and her repeated requests for a time drew only a late response that a postponement notice had been sent the day before—something she never received. Five days later the company still couldn’t give a firm date to finish commissioning, offering only reassurances that they were “working hard” on it. She has been left with a屋

YelpNov 7, 2024

L F. signed on for a rooftop solar system in November 2023 and watched the panels get installed after several schedule changes in February 2024 — yet by November 2024 the system still hadn’t been approved to produce power. They discovered the hold-up came after the initial inspection: Demand had errors in the plans and paperwork, forcing the project back through permitting and delaying a final inspection and permission to operate (PTO). What began as a months‑long wait to install ended up stretching into a year because of the company’s paperwork mistakes. They experienced near‑total silence from the company during that stretch. The only contact in September 2024 was a call asking for a favorable review and referrals — a call that landed while the system remained nonfunctional. After explaining the situation, the caller acted surprised and promised to follow up, but no one ever did. Their sales rep stayed communicative and honest for months, even admitting he was chasing Demand’s internal project managers for answers. The rep later left the industry, saying Demand owed him and other reps unpaid commissions until jobs reached full PTO; he told them he expected he might never see,

Shawn H.
YelpJul 23, 2025

Shawn H. hired Demand (aka National Energy Services) to install a 31-panel solar array and two Powerwall 3 batteries on his home, and what should have been a few-day job stretched into months of delays, roof damage, and paperwork problems. The install was cancelled the night before the scheduled date; two weeks later a subcontractor, Eletech, showed up for under four hours, installed flashing upside down, bent shingles, and drilled extra holes that missed rafters, then left for a week. Shawn sent drone photos; they at least redid some of the work, but from first start to claimed “completion” took two weeks when the scope should have taken a couple of days. The electrical work created the biggest snag. Engineering drawings showed disconnects, but installers skipped them, saying they weren’t necessary. The utility, Centerpoint, refused Permission to Operate without the disconnects, so almost two months later Eletech returned to add them — and installed used disconnect boxes with open punchouts that left live parts exposed for about three months. Demand didn’t act quickly; another two months passed before Centerpoint requested information plates, which then took a month to get putin

Andre H.
YelpDec 1, 2025

Andre H. entered a financed home solar installation expecting a professional, on-time job. He discovered months of broken promises and poor communication, and the project was ultimately abandoned. He ended up with a system that is not operational, no follow-through from the contractor, and a financing partner still expecting payments for an incomplete job. Repeated requests for updates produced silence, excuses, or being passed between people, so he escalated and is now dealing with the Contractors State License Board (CSLB) while still seeking resolution. The experience cost him time, stress, and financial confusion. His practical warning: do your research, read the fine print, demand proof of progress before releasing funds, and walk away if something feels off—he’s currently left paying into a system that doesn’t work while chasing the contractor through regulators.
