Robert C. came to my home and went over the advantages of adding a few more panels that would still keep me in tier 1 status with the power company as well as consideration of adding a Powerwall III battery. Considering the increased power generating capacity of newer panels and storage capability of the Tesla battery, I was sold by the quality and value of the expanded system. The design and contract review was done online in a timely fashion and it was a swift transition to installation taking place in just one day, as the the lead installer (Antonio) was joined with two co-workers who explained how the project would move forward and answered all my questions. The work was complete by 3pm and I was extremely satisfied with the entire process. Thank you Semper Solaris for a quality job for a fellow veteran. Dan

In 2024, I replaced my router which set off a chain of events. I was unable to connect my new router to my solar panels. I called Semper Solaris, who directed me to call Enphase, who directed me to call semper Solaris to send a technician after their troubleshooting did not work. I even reinstalled my previous router with no luck. Short story, I called Semper Solaris and they schedule me a technician for a whopping $500 service fee upfront without even diagnosing the problem. Not covered by warranty and per their management about waving the fee or reducing the fee, "Sorry, nothing they could do." I cancelled the technician. This was in 2024, and I have not been able to connect to my solar panels since then. Buyers be aware

Aaron is quick to communicate via text or phone call, and they got out to my house quickly for a quote. My solar system has been working great for years now.

Nick went over everything with me after install, including how to winterize the system. They're responsive to follow-up questions and quick to address any issues - even long after their work is done and payment is received. Would definitely recommend. Great company.

Our house has been a work in-progress. It's a 3 story cabin built in the 1930's transitioning to a…read moremodern-farmhouse style home. We've done a lot of work on the interior and have slowly worked our way to the exterior of the house. We went from an ugly asphalt rolled roof to beautiful metal roof that was installed by Valley Roof Consulting. SERVICE - This is a top notch crew! The team comes out to your property to assess what they are working with. This includes . . . - assessing the surrounding perimeter and properties to determine how your rooftop selection could impact the surrounding perimeter and neighbors. - assessing the visibility of your rooftop. In our case, the rooftop of our house is the first thing you see since we live on a hill and our property easement is above our house, therefore curb appeal becomes equally as important to us just as much as the functionality of the roof type we select. - measuring your roof top, the pitch of your roof top, and checking for areas of your roof that may require fixing or replacing. Once they assess the perimeter and the rooftop of your home, they will provide you with your options. These options are based on the assessments they've made, and the requirements by the state of California and county requirements. They will walk you through the options of available roof types, the life of each roof type, and a general idea on what the cost differences are based on the options provided to you. Once you've a decision to go with Valley Roof Consulting and decide on the roof type, the process is pretty seamless, they will be transparent and keep you informed of the status of the project, but will absorb all of the burden required to finally get you to an installation date. (By burden, this includes pulling permits that required a lot of churn with the county and city, getting the material ordered and shipped during a period where supply, demand, and transportation has been met with complexity as a result of the pandemic, inflation, etc.) ONSITE WORK - The most exciting day! Once a date has been established for the work, the team will notify you in advance of the date, and the day before the crew is scheduled to be onsite, they will contact you and let you know how much work space will be required to do the job. In our case, we live on a windy narrow road with limited parking, so knowing in advance what they required helped us to plan where our vehicles needed to be parked. Once on-site, you'll have the project manager onsite, and their crew of guys raring and ready to go! And when I say raring and ready to go, the efficiency as to how they come in, set-up and start the work is seamless. They know what needs to be done! Once they remove the old roof, they'll make sure any old wood is replaced before putting down the moisture barrier. In the situation of a metal roof, the metal panels are then molded and cut to size onsite. It was quite amazing to watch the process. Once all of the metal panels have been cut, the crew organizes the panels to ensure the installation is done efficiently. Whilst the engineer / project manager of the team knew how the metal panels were to be installed based on the shape and pitch of our roof, like any project, there's always contingencies and unknowns. This team, amazingly had to do a minor course correct, and they did it without a hitch and still got the installation done on time! THE TEAM - You'll be working with the owner and his right hand guy, and throughout the project, they are the team members that stay connected with you throughout the project. The crew that comes out to do the work are very professional, friendly, and equally as knowledgeable. At the end of each day during the job, they make sure the utilized workspaces within the perimeter of your home are always cleaned up. SUMMARY! - The result of the work, as you can see from the photo is a beautiful roof, installed with care and quality. - A great team of subject matter experts who know what they are doing, and are looking out for you. - A team who is willing to work intimately with other teams (e.g. solar company, the team who is installing the gutters, etc.) to ensure the other team do nothing to compromise the installation of the roof. The next phase of our home improvement project is the exterior of the house, and this team does exterior work too, so we will indeed be working with Valley Roofing!

We could not be more delighted with the results we achieved working with the team at Your Energy…read moreSolutions. The many moving parts to our residential solar plus battery system, including the various entities, such as PG&E, Tesla, City inspectors, and the financial backers we opted to use all progressed seamlessly and, for us effortlessly, thanks to hard working individuals behind the scenes. In particular, Skyler could not have been more helpful, managing our project and acting as a point of contact. Others included David in sales who demystified the process, Varon who coordinated with the utility to ensure we met all requirements, and Gino, who collaborated with Maxwell Power (formerly HDM Renewable Finance), the clean-energy company that helped finance our residential system. On site, the design and install team did a great job keeping things simple. The entire system, including battery and thirteen panels, was installed according to Ramiros's expert design within just four hours. Good quality hardware was used to tie to the roof, which was inspected by our roofer and given a big thumbs up for not causing problems. But even before that, David our site survey tech, gave us the sense that all would proceed well, as he collected necessary data by drone, and made a favorable first impression with his personable approach. Toward the end of the multi-month process, which included time to get a new roof installed, we passed city inspection with YES tech, Dario, an extremely courteous young man, present to ensure we made it through that last step and PTO (permission to operate). YES has an excellent and well-deserved reputation because of these people and others who worked on our behalf. The company can do better automating some of the process, and to be fair, they say they are working on transitioning to a CRM software solution for this purpose. But, I can say that over a period of several months, I had excellent communication with many helpful people. Skyler in customer service was my primary contact and that made all the difference. My thanks to YES for helping us make this wonderful and complex project a reality. We love our new YES-backed system and look forward to working with the company again in the future.

I had a frustrating experience with Your Energy Solutions regarding a warranty transfer. The…read morecontract stated that an additional charge would be incurred for the warranty transfer but did not disclose the amount. We were later charged $500 with no prior breakdown or explanation of the fee. I clearly communicated that I would be the one paying this charge. Despite that, the service department reached out directly to the buyer and asked who would be paying. This unnecessary contact created confusion and complications during the escrow process that could have easily been avoided. The lack of transparency on the warranty transfer fee and the poor internal communication caused more stress than necessary. Businesses handling real estate-related services should be more careful with both contract clarity and how they communicate with parties involved in a transaction.

Our experience with SIG has been unacceptable…read more After installation and payment, SIG solar became largely unreachable. We have made multiple phone calls over the years needing assistance with system issues and were constantly told someone would call us back. Those calls rarely happened, to the point that my husband drove 40 miles to their office just to speak to someone in person - with no resolution. Because SIG solar failed to provide support, WE had to contact the inverter manufacturer, twice in the past few years to get the system functioning, something the installer should have handled. When we just recently realized that we needed our roof replaced, SIG solar charged us $8000.00 to remove and reinstall the panels. We had to pay it because we did not want to do anything to jeopardize our warranty, effectively forcing us into this expense. This company appears focused on sales, not long-term service. For a major investment like solar, this level of non-responsiveness and lack of accountability is unacceptable. Experiences like this are why homeowners rely on consumer protection and contractor oversight agencies.

I had been meaning to write this review for a while. Synergy Power came highly recommended by a…read moreclose friend, and after meeting Eric on May 27, I quickly understood why. He was extremely knowledgeable about solar and made the process of designing our system straightforward and easy. Because I had travel plans, we couldn't start immediately, but the Syndy team scheduled our installation for Jul 27 - 28. Everything went exactly as planned. The materials arrived on Jul 24, and Martin and his crew, showed up right on time at 7:45 AM on Jul 27. They worked incredibly hard, efficiently completing most of the installation that day and returning the next day to finish the remaining panels and cleanup. That evening, seeing our panels generating solar energy for the first time was an amazing feeling! PG&E installed the Tesla Backup Switch a few days later, and everything seemed to be moving perfectly - until our Livermore city inspection on Aug 7. Unfortunately, we failed because an approved heat detector had not been installed. I was extremely disappointed. It felt like having an amazing present sitting right in front of me but not being able to open it! There were a few additional hiccups, but Jason stepped in, took ownership of the heat detector issues, and worked to get everything resolved. We finally passed inspection and received our permit on Aug 26, followed by PG&E Permission to Operate (PTO) on Aug 28. A huge thank you to the entire Synergy Power team: - Martin, Eliel, Manuel, and Nate for the excellent installation - Rebekah, Melissa, Mark, and Amy for keeping us informed - Jason for stepping in and getting the final issues resolved Overall, we are extremely happy with our solar system and grateful to the entire Synergy Power team for seeing the project through from start to finish.
