The Verdict

This company has left multiple customers with broken systems and unfulfilled promises. One homeowner paid a deposit for Tesla batteries, waited two years, received defective units from a defunct manufacturer instead, endured six months of troubleshooting, then watched those batteries fail entirely. When Synergy promised replacements, the entire team went silent. Another customer discovered their $51,800 system was severely undersized only after receiving a $1,000 utility bill at year-end, and the owner blamed them for the error. We found 46 mentions of solid workmanship, and installation crews consistently earn praise for being on time and respectful. But we also found a pattern of accountability evaporating when things go wrong. Rebate paperwork sits unfiled for over a year despite repeated calls. Systems fail and calls go unreturned. When a battery supplier goes bankrupt, customers are left in the dark. (One reviewer is now hiring a lawyer just to get the Tesla batteries they were promised months ago.)

If you're looking for a tidy one-day install with polite crews, you'll probably get that. But if something breaks or underperforms after the contract is signed, you may find yourself chasing the owner for months with no resolution.

3 Stories That Stood Out

1. Marjory Graue
Google | Feb 24, 2025 |

Three years before the pandemic Marjory paid a down payment for Tesla batteries for her home and waited for the work to be completed. Two years later, after a series of delays and excuses, Ed Costas installed two batteries manufactured by a now-defunct firm called Electirc power. For more than six months the system never functioned: installers wrestled with getting the batteries to link to the app that controlled them while the original manufacturer had already folded. She stuck with the company, hoping for a quick fix, but in December 2024 the batteries stopped working entirely. Technicians returned and promised to replace both units with new Tesla batteries, yet for the past two and a half months she has been chasing that promised replacement while everyone at Synergy 768 has gone silent. Marjory discovered that the team was quick to accept money but unwilling to stand behind the contract or the work when things went wrong; Ed’s friendly manner and big promises felt like a disguise once follow-through disappeared. Now she is preparing to hire an attorney and has begun warning others not to use Synergy 768 — the most lasting detail is the unfulfilled promise of Tesla replacements,

2. Joaquin M.
Yelp | Aug 2, 2025 |

Joaquin M. invested $51,800 in a solar system meant to cover his household electricity, only to discover a year later that the array was severely undersized and he ended up paying PG&E more than $1,000 at the annual true-up. He confronted owner Ed Cotas about the shortfall, and Cotas shifted the blame onto him. After SunPower filed for bankruptcy, Snergy768 stopped offering any assistance; Joaquin has been trying to get help since last November with no response. He walked away frustrated by what he describes as awful customer service and a costly true-up with no company support.

3. Gregory Rhodes
Google | Jul 5, 2021 |

Gregory had two power walls and additional solar panels installed 13 months ago. The equipment performs well and the installation technicians left a very positive impression. He later discovered the paperwork for a PG&E rebate was never submitted; despite many emails and phone calls, he could not get Ed Cotas to complete that portion of the contract. What lingered was the contrast: a functioning system and good on-site service, but an unresolved rebate because the required paperwork never made it to PG&E.

What You Can Expect

01

1. Dante Galura
Google | Aug 13, 2024 |

For Dante, what made Synergy 768 memorable wasn’t just a smooth panel job — it was that owner Ed Cotas personally installed their Tesla wall charger at no cost. Dante met Ed for the initial consultation and quickly discovered a level of professionalism, thoroughness, and technical know‑how that put him at ease; Ed walked through the benefits and the installation process in clear, practical terms so the decision felt straightforward. After PG&E cleared the permit, the crew arrived and wrapped the solar install in a single day, working cleanly and efficiently and demonstrating real skill on the roof. A year and a half later he’s still pleased with system performance, and credits Ed’s leadership for the team’s customer-first approach. The detail that sticks most is simple and tangible: the owner not only handled the sale and coordination, he actually installed their Tesla charger free of charge — a gesture that turned a very good installation into a personally attentive experience.

2. Dawnmarie Fehr
Google | Aug 8, 2024 |

Dawnmarie had Synergy768 install solar panels at her home 18 months ago and then hired them again in October to put in a Tesla home charger. She found both projects finished on schedule and within the original budget, because Ed, the owner, walked her through the scope and costs up front so there were no billing surprises. The installation crews behaved politely and worked cleanly, tidying the yard each day before leaving. Over the past 18 months the panels have performed well, and Ed arranged financing options that fit her budget so the upgrades felt affordable. What stayed with her was the combination of clear pricing, workable financing, and crews that left the property neat—so she ended up with predictable costs, reliable equipment, and a cared-for yard.

1. Vijay Pannu
Google | Aug 9, 2024 |

Vijay Pannu had solar panels installed on his home several years ago and has been extremely pleased with the outcome. He remembers the installation crew arriving on time every day, treating the property respectfully, and talking him through what they were doing as the job progressed. The system has run without problems since activation. The detail that sticks with him is the combination of punctual, communicative installers and a trouble-free system—exactly the sort of result future buyers would want to expect.

2. Ruel E.
Yelp | Sep 5, 2021 |

Ruel installed a 5.550 kW SunPower array on his home and quickly discovered it could easily handle charging his Tesla. He found the company's customer service excellent and the installation crew consistently professional and courteous. After a year he expanded the system with additional panels and added a SunPower SunVault energy storage unit to boost savings and capture more of his solar output. The storage brought two clear benefits: reliable reserve power during outages and a safer lithium iron phosphate battery chemistry, paired with a more powerful 6 kW inverter. Ed and his crew again exceeded his expectations on workmanship and professionalism. He’s already planning to increase the SunVault capacity further with the goal of becoming fully independent from the grid.

1. Ira S.
Yelp | May 20, 2020 |

Ira had two Tesla batteries installed on his home and found the whole job impressively tidy — everything left neat and clean, with no visible wires. He discovered the batteries mesh seamlessly with the Synergy solar array installed a couple of years earlier, and he walked away pleased with how well they perform. Working with Ed, the owner, felt straightforward; Ira valued that the crew showed up when they said they would and charged the price they quoted. What stuck with him most was the spotless, wire‑free installation and Ed’s reliability.

2. Esther F.
Yelp | Jul 27, 2018 |

Esther met with Lala Ignacio, Repower Solar’s VP, for an initial consultation more than a year ago; Lala pulled up her home’s energy history, walked through rising utility costs, and designed a system sized precisely to their actual usage. Lala backed the plan with real data about payback and long‑term savings — and it proved true: the new array has covered her monthly electric bills for three months in a row. The installation crew impressed with speed and skill, and Ed Cotas, the company president, later came out to provide hands‑on education about how the system works. Both Lala and Ed stayed available for follow‑up questions, and Esther felt the company showed real commitment to the project and to helping the environment. Her key takeaway: a data‑driven design that began paying bills within months, plus a responsive leadership team worth calling if you want a straightforward, tailored solar solution.
