Safe a Lot Solar is an exceptional company. Not only have they installed my panels and batteries which work fine, but their follow-up when problems arise is next level. I first had panels installed with them about 10 years ago. Since then, I have expanded the system with additional panels and batteries. These installations have been efficient and professional. But the follow up is what sets this company apart At this point, solar companies have sprouted up everywhere. Consumers can't know if the company will last and if they do last, if they will stand by their work. Too often, companies court the hell out of you until they get your money. Then, crickets Save a Lot is a local company that stands with its customers and the community. Over the past ten years, I've called them out for problems. Each time, they have been responsive and fixed the issue. This includes one time when I was out of town and concerned about how a power outage would affect my 90 year old mother. They interrupted an evening birthday celebration to restore our power. This company goes above and beyond. They install high tech equipment with old school values. You won't regret using them for this major home investment

It has been a pleasure to work with John Orfali and his team at Save a Lot Solar. We had vetted atleast 8 other solar installer companies and no one came close to the quality of customer service that Save a Lot Solar provides. All the other companies wanted us to sign their contracts even before they come to our house to inspect and evaluate our situation. John is the only one who readily offered to come out to our house to make sure that our existing electrical panel is properly set up for the solar PV system installation so that we would not have any surprise additional cost to our estimate. He spent 1.5 hours speaking to us and thoroughly demonstrating how the system and associated software works. We are very detailed oriented and somewhat techy people and John patiently answered all of our questions. John and his team worked efficiently to get us on board before the NEM 2.0 agreement changed to NEM 3.0 on April 14, 2023 where PG&E credits solar customers a much lower rate for the energy that they export to PG&E grid. Unlike so many contractors that we have dealt with in the past, John's team showed up on time and installed our system efficiently. As soon as the system is up and running, they immediately followed up by sending us web links to install and activate the Enphase software so that we can track how our solar system is running. Recently, a year and 4 months after our system was installed, the Enphase IQ Gateway which delivers solar production and energy consumption data to the Enphase application broke down and we were left without solar energy. We called Save a Lot Solar for help. John got back to us very quickly and his team was able to replace the part within 3 days. It did not cost us a penny but cost John's company a lot of time and money. Yet, they stayed true to their promise to support their customers beyond the installation of the solar system. This is exactly why we had hired Save a Lot Solar. With most other companies, you would most likely have to call the vendor (Enphase) yourself and deal with longer response time. We are happy to support small local business like Save a Lot of Solar. The price tag for our solar installation project was higher than some of the estimates by larger solar companies, but John and his team is worth every penny. Not only are they highly skilled, knowledgeable, and professional, these people are just honest and extremely nice folks. We cannot say enough positive things about Save a Lot Solar: If you want a reliable company that will have your back beyond the initial solar installation, we highly recommend this company.

Trust A Lot would be a great name for this company. That is the experience we felt working with John. He was on time, responsive, informed, patient... he answered all the questions we had, big and small, with respect. We never felt he was trying to "sell" us something which was not our experience with other companies. Also, the installation went exactly as planned. In general, customer service feels like a dying art these days, but John brings it all back! A year later when we were having trouble reading the panels due to wifi issues, he quickly came over, suggested we get an extender and then WENT AND GOT IT FOR US, as well as helped install it. John really stands behind his work. And, after a full year of having our panels, the electric bill was only $3. We canʻt recommend Save a Lot Solar enough.

Save a Lot Solar installed solar panels and battery storage on our 100 yr old bungalow 1 year ago They were referred to us by our neighbors. The installation was very smooth, leaving a clean work site with minimal disruption. The biggest factors for there success in the industry is the support and guidance with the design, regulatory compliance and set up with the local energy provider and the simplicity the information presented to us to make the right decisions for us. They really do it all effectively and quickly. Anything needed from us was explained simply and clearly. One year on we sit in a cool house in the summer for $50 per month. We are cool customers literally Marlene

Save a Lot Solar Yesterday, August 23, 2024, almost to the day last year that Save a Lot Solar installed Solar Backup Batteries at our Oakland home, PG&E had an “Unplanned Outage” in our neighborhood. The batteries took over immediately and powered our house for three hours until the grid was restored. No interruptions and no resetting of digital clocks. Whew! We have had a great relationship with John Orfali, Save a Lot Solar’s Owner, from when he first installed an 18-microinverter array (4.9 kW DC) on our rooftop in August 2016, to last year when we eventually contracted with John to install a three -backup battery system (10.08 kWh). He even came to our home once, when our insurance company required us to switch out our home’s older electric panels and replaced those panels. (Even when no solar electricity components were involved, John was there to accommodate our electrical needs.) So, when we finally decided to invest in solar-backup batteries, there was no question to whom we would turn, we called John. You should too. We have been impressed with John Orfali’s integrity and patience. He takes the time to make sure that one understands how the solar systems work and how they will benefit the homeowner. It has been eight years since we first became customers of Save a Lot Solar and we could not be more pleased with the company, its team and its installers.
