"Saul and Juan arrived on time, determined where the fault lay, advised me on what I can do to save some labor costs by running wire myself. I have worked on some electrical equipment over the years so usually am familiar with what is needed or not needed. These guys didnâ  t try to sell me something I didnâ  t need. Very professional and I would recommend them to others. Thx. Brian Napa County"

"Leo was amazing and especially thoughtful and caring with my elderly mother and her home in regards to solar installation. He was thorough with his explanations. He intelligently and professionally answered all questions. There was no pressure and he was communicative with the family. I would not hesitate to recommend Leo for solar installation if value and integrity are a priority for you."

"I have had a few different solar companies come and do an estimate for me and the experiences were not bad. Solar Sesame came in and gave me a FULL breakdown of how it worked and they were so transparent plus the price was way better than my previous quotes. Zack was so thorough and answered all of my questions and really took his time to answer every single question I had. The installation was so seamless and done in a day. The crew was fantastic as well and I’m so happy that I went through with this. The system has been working great and I have not been paying these high PG&E bills ever since. HIGHLY RECOMMENDED. I have referred my friends and family to Zack and Solar Sesame and they even sent me hundreds of dollars in gift cards for doing so. I couldn’t say enough about them. If you have even been thinking about doing this, do it!!!"

"I had Soltari install my solar panels and I’m really happy with how everything turned out. I was a little nervous going into it since I didn’t know much about the process, but they made it super easy to understand and handled everything. The team was professional, respectful, and just really easy to work with. They showed up when they said they would and made sure everything was done right. Now that it’s all up and running, I’m honestly so glad I decided to go with them. I’d definitely recommend them to anyone looking into solar 😊"

Customers say: True professional

"We found McCormick home builders through Angie’s list. They were not one of our original contacts, but they contacted us and came out to give us a quote. Matteo was extremely helpful, informative, honest, and gave us reasonable realistic prices, and did not try to inflate the prices or pressure us in anyway. We felt very comfortable with him immediately. We felt like he was a member of the family that we could just talk to and ask questions he was very personable. He gave us his contact number in case we had other questions and he was always available when we needed him for any type of questions or concerns. Mateo‘s team did a beautiful job. They were fast. They were efficient. They cleaned up beautifully. They did a wonderful job. They were very considerate of our time our needs and our neighbors. They were an absolute pleasure to work with. I would highly recommend Matteo from McCormick home builders for any home building projects, and we will be calling him again in the future!"

"Unfortunately my husband s company is moving us to the midwest. Even though we had a signed contract with Rick and Teresa at Sunriver Solar, they we very understanding and basically told us not to worry about it and to enjoy our next adventure. They even asked if they could help us with any of the moving stuff!!! They are a delight to work with, they do everything, they kept us up to date on what was going on, and, even though we could not work with them, we would highly recommend them. You really cannot go wrong with Sunriver Solar."

FAQs for solar panel installation projects in Los Altos, CA

A single Tesla Powerwall provides backup power for essential home circuits for approximately one day during an outage. This duration varies significantly based on which appliances and systems you're powering. Critical loads like refrigeration, limited lighting, internet equipment, and a few outlets might draw two to five kWh daily. With 13.5 kWh of usable capacity, careful energy management is necessary for extended outages unless you have solar panels to recharge during daylight hours.

A Tesla Powerwall can power most residential air conditioners, as its 5.8 kW continuous output handles the three to four kW requirement of standard AC units. However, running air conditioning substantially increases energy consumption, potentially depleting a single Powerwall within several hours. For meaningful climate control during extended outages, multiple Powerwall units are recommended. Solar panel integration helps replenish the batteries during daylight hours, extending your cooling capabilities.

Tesla Powerwalls qualify for the federal Residential Clean Energy Credit, which offers a 30% tax credit through 2032, followed by 26% in 2033 and 23% in 2034. This represents a tax credit (direct reduction of tax liability) rather than a deduction. To qualify, the system must be charged primarily from renewable energy sources. Additionally, many states and utilities offer supplemental incentives that further reduce effective costs. Consult with a tax professional regarding your specific eligibility and filing requirements.

Unlike conventional generators that require fuel, maintenance, and produce noise and emissions, Tesla Powerwalls operate silently and automatically without ongoing fuel costs. While generators can run indefinitely with refueling, Powerwalls have capacity limitations unless paired with solar recharging. Traditional generators cost less initially but require regular maintenance, testing, and fuel storage. Powerwalls offer additional daily benefits through energy bill management and smart home integration features that generators cannot provide, making them multifunctional investments beyond emergency backup.

Tesla Powerwall systems require minimal ongoing maintenance compared to other backup power solutions. Unlike generators with moving components requiring regular servicing, Powerwalls function virtually without mechanical intervention. The manufacturer recommends keeping the unit's surroundings clean and ensuring proper ventilation. For systems paired with solar panels, periodic panel cleaning (costing between $295 and $625) helps maintain optimal charging efficiency. The system conducts automatic self-diagnostics and receives software updates remotely, with most potential issues identified and addressed through Tesla's monitoring capabilities.
