The entire team worked in a seamless and coordinated manner. Their collaboration with Westco/Berkeley Roofing services made the entire process well organized.

They managed to get our system complete in early December with plenty of time to spare. Thank you Mary, Charles, Miles, Stephen, and everyone else!

Waiting for city inspections is never fun, but was amazed that Luminalt's schedule hit the install date exactly, they got the job quickly, and follow up inspections happened sooner than promised.

The home insurance "fixed" the issue by installing a fan booster. It never worked even when they came back to recheck the booster. Juan came over and found the issue almost right away. The wiring from the AC unit was never connected to the fan boosters!!!! In 2 years we've have 4 other HVAC companies come and tell us we needed a whole new system, which would have cost us 20k.

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.

Hello everyone, I…read morehad a great experience with Solar Sesame. I had my system installed in December 2025 and wanted to wait a bit to see how SS and GoodLeap handle follow-up on the project, Closeout issues, and customer service follow-up. Since my December 2025 installation and the January 2026 activation with PG&E, I have been more than happy with their service. I had put off getting solar for a while (bad decision on my part), so when the $1,100 PG&E bill came in last summer, I knew it was time for a change. Solar Sesame's pricing consultation was pleasant and informative. I had done plenty of research, so I knew my stuff, and being in Construction helped as well. Both their Sales Rep and Installation Lead were informed and knew their stuff. My Project Submittal documents to the City of Danville were professionally done. The building permit was obtained quickly, and the installation was completed within a few days. We did have an initial hiccup with the materials delivery; it arrived too early, but SS had it picked up and redelivered the following week. All in all, a solid performance from Solar Sesame!

My wife and I have struggled for years with staggering Pacific Gas and Electric bills ranging from $300 to $600+ per month. Most of our friends have bills ranging from $100 to $200 per month here in Pacifica. We hired an energy consultant. He spent a day at the house. He wrote a most professional report. To make a long story short, we had to gut our roof and rebuild the entire attic of our home to solve the problem. We were looking at a bill of $40,000 or more. I rejected this. I felt that solar panels were the answer. Over 5 years, four solar companies came out. Sometimes an engineer came along. They did in-depth quotes with a cost of over $40,000 that did not work. This is due to the fog and vegetation blocking the sun. On the fifth try, I brought Occidental Power Solar Company. They did a professional job. They proposed a system costing $27,000 that would do the job. Despite protests from my wife that the system would never work, I hired this company. I got one heck of an education in solar power. We encountered an initial problem that their system required a 150-amp power box. We had to upgrade our 100-amp power box. Pacific Gas and Electric got involved. There was a lot of bureaucracy and delays. A new transformer had to be installed in front of our house. This was an all-day operation with 3 giant trucks involved. Occidental installed the solar panels on our roof and the support equipment. A permit had to be obtained from The Pacific Planning Commission. A final inspection of that permit opened the way for Pacific Gas and Electric to turn on the solar power system. It took them almost a month to do this. There is a saying in English that I love as follows: "The proof is in the pudding." Early this morning, our first electric bill arrived after the solar power system was turned on. It was only $29.89!!! Occidental Power Solar Company had exceeded all my expectations.
