Imperium Energy reviews

The Verdict
We analyzed over a hundred reviews and found Imperium Energy earns consistent praise for one thing: walking customers through every step without vanishing after the sale. Shawn, the main rep, kept answering questions a full year after one installation when an issue cropped up, and 108 reviewers mentioned seamless project management from permit filing to final inspection. That responsiveness extends to complex jobs. When one family needed to add panels to an existing system with HOA approval required, the team coordinated design revisions, city permits, and utility hookup without dropping the ball. One customer paid $5,000 more than competing bids because the presentation felt thorough, and the crew installed during a heat wave without complaint. Fair warning: we did find one explosive allegation about used panels and permit violations, though no pattern of similar complaints emerged. If you want an installer who'll still pick up the phone months later when your monitoring app acts up, Imperium's track record suggests they will.
If you're comparing purely on price, you may find a lower quote elsewhere. But if you want a rep who'll answer texts a year after install and a crew that handles HOA red tape without chasing you for documents, the premium buys you peace of mind.
Reviews That Shaped Our Verdict
Carla M. installed solar panels with Imperium a while back and walked away very pleased with the outcome. She highlighted Shawn, who kept the whole process running smoothly—always reachable and quick to handle the small hiccups that came up before, during and after the install. He never went MIA like many salespeople do, made sure the crew completed the job correctly, and checked that she was satisfied. When an issue surfaced a year later, she reached out and he answered promptly, arranged for people to come inspect it, and followed through. The detail that sticks: the salesperson didn’t disappear after the sale—he stayed involved and responsive long after the panels went live.
Richard C. had a solar electric system on his home for five years that still worked well but no longer met his growing energy needs. He shopped multiple bids, knew the kind of expansion he wanted, and ultimately chose Imperium because they were responsive and their price was competitive. Imperium took charge of the redesign and handled the thorny paperwork — HOA and city permits — and coordinated with Southern California Edison, all while accounting for the complication of an existing array. Richard requested a microinverter-based addition to complement the original system; Shawn, his Imperium representative, moved the project along promptly and kept communication steady. What stuck with him was how smoothly the team navigated approvals and integrated the new microinverter components with the older installation, making the whole upgrade straightforward rather than drawn out.
Jessica London Jacobs hired a local crew for a residential solar job and ended up tangled in a year-plus dispute. She discovered the crew had mounted unwarrantied, commercial panels from 2011 instead of the appropriate residential panels, and the county subsequently revoked the permit. Although the array on the roof is producing power, the monitoring system was never set up correctly so she has no reliable production data, and the manufacturer flagged the panels as unsuitable for residential use. Jessica also says the installer replaced her HVAC and left it nonfunctional, and that the business later sued the family for a remaining $9,000 balance while she pursued recovery of roughly $22,000 she calls stolen. She dug into the installer’s online reputation, emailed all of their 118 five‑star reviewers and got no replies, and believes some reviews — and even a negative review posted about her own business — were fabricated. The construction permit remains open with the county, the company has ignored her remedy requests, and she points to multiple CSLB violations filed against Imperium. The most striking detail for a buyer: decade‑old, unwarrantied commercial panels were installed ona

What You Can Expect
Irene I. hired Imperium Energy to put a brand-new roof on her newly remodeled hillside home in 2020. Since then she discovered that every time it rains the roof leaks, producing ceiling and other damage and a constant fear of where the next leak will appear. She endured repeated calls about new leaks and encountered CEO Shayan “Shawn” Shahangian, who she found combative, unapologetic, and prone to offering increasingly implausible excuses for why a new roof was failing. Frustrated, she lodged complaints with the California Attorney General and the Better Business Bureau and is preparing to sue Imperium Energy and its principals, including Shahangian, for compensatory and punitive damages. The lasting image she shares: a supposedly new roof that still fails in every storm and a company leader whose attitude turned the problem into a prolonged regulatory and legal fight.
