Sales & proposal integrity
Sales Integrity6.7/10
Reviewers more often describe the sales process as clear and straightforward, with several saying expectations, costs, and next steps were explained in advance. Still, a meaningful minority report broken promises or a mismatch between what was described and what was ultimately delivered, so this category reads as positive overall but not cleanly so.Solar.com's composite of published customer feedback, not a customer quote
Clear explanations upfront. Several reviewers say the team explained the process, benefits, and costs clearly before work began, which helped them feel confident in the decision. Representative review excerpt: "He clearly explained the benefits and installation process, making us feel confident in our decision."
No-surprises pricing discussions. Some reviewers report that job costs were laid out in advance and that the experience matched what was described during the proposal stage. Representative review excerpt: "Ed, the owner, explained each job and its cost ahead of time and there were no surprises."
Promise gaps. A few reviewers describe situations where they felt promises were not fully carried through or that the final outcome did not match what had been communicated. Representative review excerpt: "They promise a lot just to get the job but they never accomplish what they promised....."
Price & financing transparency
Price Transparency6.7/10
Price transparency draws limited but mostly positive feedback, with one reviewer noting that costs were explained ahead of time and there were no surprises. The main complaint pattern is around rebate timing and paperwork follow-through rather than broad pricing confusion.Solar.com's composite of published customer feedback, not a customer quote
Costs explained in advance. One reviewer says the owner explained each job and its cost ahead of time, which made the pricing feel predictable. Representative review excerpt: "Ed, the owner, explained each job and its cost ahead of time and there were no surprises."
Rebate paperwork issue. A reviewer reports that paperwork tied to a rebate was not sent on time, pointing to a follow-through issue around incentive timing. Representative review excerpt: "However, the paperwork for a rebate was never sent to PG&E."
Communication & coordination
Communication7.1/10
Most reviewers describe responsive communication, clear handoffs, and good project coordination from permits through completion. The complaint pattern is narrower but real: a few reviews mention weak follow-through, difficulty getting updates, or projects that were not finished as expected.Solar.com's composite of published customer feedback, not a customer quote
Kept customers informed. Several reviewers say they were kept informed throughout the process and had questions answered promptly. Representative review excerpt: "They kept me informed throughout the process and were always ready to answer any questions I had."
Permit and project support. Some reviewers describe the team as actively helping with permits and overall coordination, which made the project feel organized. Representative review excerpt: "From assisting me in obtaining the necessary permits to ensuring the smooth completion of the entire project, this team demonstrated a deep understanding of the process and delivered top-notch results."
Follow-through gaps. A few reviewers report that communication became difficult during later stages, with repeated calls or emails not leading to closure on outstanding work. Representative review excerpt: "I emailed and phoned many times but could never get Ed Cotas to finish this part of his contract."
Timeline reliability
Timeline Reliability7.1/10
Timeline feedback is mostly favorable, with many reviewers saying the process moved efficiently once permits were in hand and that the company handled the activation steps well. There is one clear watch-out about delayed completion on a later promised item, but it appears to be the exception rather than the rule.Solar.com's composite of published customer feedback, not a customer quote
Efficient completion after permits. One reviewer says the installation was completed very efficiently after permit approval, taking only one day. Representative review excerpt: "The installation, after the initial PG&E permit approval, was incredibly efficient, taking only one day to complete."
End-to-end handling of activation steps. Reviewers also say the team took care of permits, utility coordination, and training as part of the overall process. Representative review excerpt: "They took care of everything including permits, PG&E, batteries and training !"
Delayed promised follow-up. A reviewer reports waiting for months for a promised follow-up installation and says communication went quiet during that period. Representative review excerpt: "For the last two and a half months I have been trying to get them to install the promised Tesla replacements but now everyone at Synergy has gone silent."
Workmanship & site care
Workmanship7.8/10
Workmanship and site care are among the stronger themes in the reviews, with many customers praising the installation quality, professionalism, and attention to detail. Only one complaint points to unprofessional workers or poor execution, so the overall picture is strongly positive but not perfect.Solar.com's composite of published customer feedback, not a customer quote
Professional installation teams. Reviewers frequently describe the crews as professional and say the finished work looked good and functioned as expected. Representative review excerpt: "I recently had the pleasure of working with Synergy768 for some electrical work and air conditioning installation in my garage, and I couldn't be more thrilled with the results."
Repeat business and added work. Some reviewers say they returned for additional projects, including solar, chargers, and other electrical work, which suggests a positive experience with the crew's workmanship. Representative review excerpt: "This is my second time working with Synergy 768; the first time, they installed solar panels."
Poor workmanship complaint. One reviewer describes the workers as unprofessional and says the job was not done correctly, which stands out against the mostly positive feedback. Representative review excerpt: "This company has nothing but unprofessional workers that can't no even do their job the right way."
Long-term support & performance
Long-Term Support5.0/10
This category is more mixed than the others. Many reviewers describe strong installed-system performance and positive experiences with design and post-install results, but the lower score reflects limited evidence and at least one complaint pattern around support after the system was already in service.Solar.com's composite of published customer feedback, not a customer quote
Positive system outcomes. Several reviewers describe good results after installation, including solid system design and successful solar-plus-storage projects. Representative review excerpt: "Synergy 768 executed a very nice design for an expansion of our existing solar/battery system."
Respectful install-day performance. Some reviewers say the installation crew was respectful and on time, which supports a positive view of the experience leading up to turn-on. Representative review excerpt: "The staff that installed our panels were respectful and on time every day of the install."
Post-install support concern. A complaint points to difficulty getting later service or follow-up work completed after the initial install, suggesting support can be less reliable once the system is already operating. Representative review excerpt: "Two years later and a lot of excuses Ed Costas installs two batteries from a now defunct company called Electirc power."
