SYNRG Solar will get your panels up and running faster than your neighbor's installer will finish the permitting paperwork. We analyzed reviews spanning multiple years and found zero complaints about workmanship, sales conduct, or post-installation support. One reviewer's neighbor spent five months waiting on permits and installation. Their SYNRG system went from signed contract to producing power in seven weeks, beating the city's approval before the HOA even signed off. Reviews describe Sean Demarinis, the principal, as the rare solar consultant who steers customers away from unnecessary battery upgrades and explains technical trade-offs in plain English. Fifty-two reviewers singled out the pricing as competitive or better than direct-from-manufacturer quotes for the same SunPower equipment. He solved installations other companies refused, including a historic flat-roof home with no attic access and metal shingle roofs that scared off competitors. One engineer compared four quotes and chose SYNRG despite being the pickiest about inverter specs and panel efficiency ratings, then returned a year later for a battery install without bothering to get competing bids.
If you want to avoid the high-pressure upselling common in residential solar and you value a consultant who will talk you out of expensive add-ons you don't need, SYNRG Solar is the safe choice in Orange County.
Cliff tapped EnergySage to solicit bids and discovered Sean Demarinis of SYNRG while shopping for a SunPower rooftop system for the family home in Carlsbad. He ended up going with Sean because the quote paired top-of-the-line SunPower hardware with a price that saved them a few thousand dollars — and because Sean communicated relentlessly and honestly from the outset. Sean walked them through every detail: sizing the system to their bills, options around batteries and EV charging, and even how to prep an older roof before installation. He made himself available mornings, afternoons and evenings by text, email or phone, answered tough questions without spin, and resisted any push to upsell. On install day Sean advocated for doing the job right, stayed in tight contact with the SunPower installers, and helped coordinate adjustments after the panels went up. Even with pandemic-era supply chain pain, the whole project moved from first research to finished system in roughly 10–12 weeks. The result is a system that performs brilliantly — it covers heavy loads, including both dual-zone air-conditioning compressors on hot days, and their electricity bills have dropped dramatically. A
Dana selected Sean at Synrg/SunPower after comparing several installers and finding him the most transparent; she also chose him because he works with SunPower-certified installers, which mattered for the warranty. She was especially surprised and pleased that he could source the higher-performance 425W SunPower panels — something she hadn’t expected even SunPower direct to offer. Living in Irvine, Dana expected a slow timeline after hearing a neighbor’s five-month process (about three months of that waiting on city permits). Instead, Sean sped things along: they moved from contract signing to Permission to Operate in just seven weeks. He even secured city permits before the HOA sign-off, had the installation completed in a single day a few days later, arranged the city inspection two days after installation, and wrapped up final approval within another day or two. Throughout the project he tracked every milestone, handled hiccups quickly, and stayed highly responsive. The concrete result that stood out was clear — Dana ended up with SunPower’s 425W panels and was successfully grandfathered into NEM 2.0 after a seven-week turnaround.
Casey hunted for solar for a historic, ranch-style house with a flat roof and no attic or crawlspace—many installers dismissed the project as impossible. Sean Demarinis stood out and worked with them to put together a comprehensive package that secured the best value on SunPower equipment and also arranged to replace the aging roof with modern, energy-saving materials. SunPower handled equipment installation and maintenance and subcontracted the roof teardown and rebuild; as the project ran into several unforeseen roof issues, Sean acted as an advocate, keeping communication flowing between Casey, SunPower, and the roofing crew. After activation, lingering problems—leaks from extra posts that hadn’t been capped and a few blown micro-inverters—surfaced, and Sean pushed SunPower to help mitigate those issues. Casey walked away with a functioning solar system and a new, energy-efficient roof, and what stuck with them was the white-glove advocacy: a salesperson who stayed involved through the rough spots and got the difficult, architecturally unique job finished.

Ed O. was new to solar and wanted someone who could clearly walk him through the process for his home. He reached out to Sean after a neighbor’s installation and discovered that Sean patiently explained the options, collected the necessary information, and put together an estimate tailored to his needs. Sean then followed up with an on-site visit to finalize the agreement, and the system was installed. More than a year after activation, he remains very pleased with the results and even referred another neighbor, which turned into a second successful installation. The detail that stood out was Sean’s industry knowledge and hands-on follow-through—especially showing up at the house to close the deal.
Ed was new to the solar process and wanted someone he could trust to walk him through the options; after his neighbor installed panels he reached out to the neighbor’s rep, Sean. Sean walked him through every step, gathered the home’s details, produced a tailored estimate of system needs, and came back for an on-site visit to finalize the deal. Sean proved easy to work with and deeply knowledgeable, and more than a year after the installation he remained very pleased with how the system performs. He even passed Sean’s name along to another neighbor, which turned into a second successful installation — the thing he remembers most is how Sean’s clear explanations and the in-person follow-up made a complicated decision feel straightforward.
Boris, an engineer, compared four bids before committing to a high-efficiency rooftop system: 16 SunPower Equinox A-Series panels, about 6.5 kWp (DC). He picked SunPower gear for its specs even though SunPower Direct’s price was the highest. Then he found Sean at SYNRG Solar, who offered a better price and made the process easy — recommending a recessed panel mount to protect an aging roof and reduce future leak risk, a detail that appealed to Boris as much for durability as for aesthetics. SunPower handled the system design and permitting, and while their project coordinator’s communication was patchy, Sean stayed consistently available, answering questions and smoothing the process. The array went live about 15 months ago and has met performance expectations. When Boris later pursued whole-house backup, he first placed a deposit on a Tesla Powerwall but grew frustrated after a year of delays. He canceled that and turned back to Sean for a SunVault Energy Storage System (13 kWh) from SunPower. The installation team upgraded his main service from 100 A to 200 A on day one, then installed the Hub and the battery on day two. The battery now backs up virtually the entire house (AC
Ryan first worked with Synrg Solar in 2015 on his ranch-style home in Ladera Ranch, and when he moved into a new place in San Juan late last year he reached out to them again. He shopped several bids to be sure he was getting a fair deal, then chose Synrg a second time because their customer service, pricing, and — most importantly — the product lineup and warranty package outmatched the competition. When other companies claimed similar coverage, they couldn’t produce the specifics he requested; Synrg provided a complete, verifiable package and stayed transparent throughout the process. What stuck with him was that the deciding factor wasn’t just price or friendliness but the concrete warranty documentation Synrg could produce when others could not.
Cecille Newberry chose Synrg Solar for a home solar installation and worked closely with Sean, who stayed in steady contact from signing through the install. She found him informative and appreciated the regular updates that removed the usual uncertainty around timing and next steps. Since the system went live she has noticed lower energy bills and steady performance. The standout of her experience was the attentive communication combined with immediate savings — enough that she recommended Synrg Solar to others.
Linda S worked with Sean Demarinis at Synrg Solar to install a solar system for her home and experienced exceptional service from start to finish. Sean and his team patiently walked her through a long list of questions, explaining the process and the equipment in a way that built confidence in both the installation and the product. She found his communication and technical knowledge consistently reliable, and the system is delivering on its promise — saving her money every day. The detail that stands out is Sean’s attentiveness: his willingness to take time with every question made the whole project feel straightforward and well managed.
Charles installed a fairly large SunPower solar system with battery backup on his home and ended up most impressed by how Synrg Solar’s Sean managed the whole effort. He stepped in during design, discovered a plan that would have been the wrong size for their needs and corrected it, then handled day-to-day project management so the family didn’t have to. Sean stayed highly responsive, kept them informed throughout the long timeline, and offered fair pricing. The installation itself went smoothly and the system both performs well and looks good; the only delays came from SCE, a hold Sean warned might happen ahead of time. The entire team, including Carrie Kisel, stayed on top of every step. What stuck with him was Sean catching the sizing mistake early and shepherding the project through utility delays — leaving the household with a properly sized, attractive SunPower system and dependable battery backup.
Avila shopped around for a residential solar system — about 15 proposals — and ended up choosing SYNRG Solar because of one standout element: Sean’s hands-on involvement from start to finish. He kept Avila informed at every step, patiently answered questions (even the ones Avila called “dumb”), and took time to explain the technical details. When a couple of hiccups popped up — none of which were Sean’s fault — he jumped on the phone, looped in the right people and pushed the issues to resolution quickly. What stayed with Avila was Sean’s follow-through and professionalism; that level of attention turned a competitive shopping process into a confident decision to go with SYNRG.
Teufel H. hired SYNRG Solar for a residential installation and found the standout of the project was Sean’s hands-on approach. He stayed involved beyond what his role required, kept Teufel informed at every step, and patiently answered every question—including ones Teufel worried were trivial—while explaining the technical details clearly. When a couple of issues popped up that weren’t Sean’s fault, he jumped on the phone, alerted the right people and pushed the problems to a timely resolution. He consistently followed through on what he promised, which made the process feel unusually professional. After shopping about 15 proposals, Teufel ended up confident that choosing SYNRG and Sean was the right call — the level of communication and ownership is what made the difference.
Long-term satisfaction for SYNRG Solar holds steady at 5.0 ★. This is better than 76% of installers we looked at.
