As I was left holding the bag, I discovered that that company did not generate a permit either before of after installation so I had to scramble to get that issue resolved to get the proper inspections completed. I got hold of Chris at Aztec and he was a fountain of great information. Chris gave me the information and contacts as to how to get my project to the inspection stage. Chris went totally out of his way to help me. As hindsight is 20/20 I wish that I had started with Aztec from the start. This company is the only one you will need to contact regarding all of your solar needs. If I could rate them higher than 5 stars I definitely would. Irv S.

From the moment of the quote and all the way to completion. They provided easy and transparent communication and guidance along our project. The staff named Tanner, was extremely professional and knowledgeable. He made my experience lasting, and to be honest with you, they get my future business for any plumbing, electrical, heating and solar maintenance. They were an absolute professionals, they not only cleaned up after the project , they made sure the project was done timely and throughly! Shout out to the other staff members who assisted on scene Triston, Matt, Erik, and Octhavio. You guys rock, you all deserve cigars To the CEO, these staff members deserved recognition especially Tanner, who represented your company at a gold standard! Thank you for putting my mind at ease during this project.

This company is a joke. The only reason we started with them is because our unit had been purchased…read morethrough them, and therefore warranty would be secured- except that no, because warranty is not transferrable. Still, they talked us into sticking with them and signing up for recurring maintenance program for "discounts" and covered service. Worst decision ever. Every single time I call trying to schedule service they never have anything for 1.5-2 months out - even though we pay a membership every month and are promised "priority scheduling". The services are over priced so that they lie about giving you "the member discount". They even states I needed to re-do stuff I've done on the prior service as if it was never done previously- liars, trying to sell unnecessary work. Finally, a local person is never available to talk to on the phone. You always get transferred to a third party person who doesn't care at all. I just want a refund for the 6 months paid of membership that I won't use, and cancel this nonsense. Never again. Stay away! they tell us you have priority for scheduling maintenance bit you don't

As explained by Brock the project required permits, approvals and building inspections that add months to the timeline but ES Solar oversaw all the permits and approvals and sent a technician to every inspection. ES Solar staff kept in touch and updated on all the progress. Since the system was commissioned about five weeks ago it has operated flawlessly. My first SMUD bill showed a 80% reduction in kWh from the same month last year. I received the subsidies from both SMUD, PG&E plus a $1000 from Tesla. I highly recommend ES Solar if you are considering a Tesla battery installation.

The staff kept me informed throughout the process and explained how everything worked, so I learned a lot. Although it was expensive, I expect a 6-7 year payback unless PG&E rates go up, in which case it may be sooner. Overall, I'm delighted with the results.

BE Very Careful - They ripped me off - First the company came over to check out my house to…read moreevaluate what is needed and if the main system needed to be updated. Remember I said they came by the house to evaluate if they could do the job - then they submitted the invoice to me and had me pay for the deposit of $2,000.00 - Once they came out a few months later - they had no idea how to bolt down the panels to my roof nor how to get on my roof when I informed them that they needed to bring plywood otherwise they would ruin the tiles. I was told people would get back with me - No one ever did - SMUD came out twice ready to turn off the power to the house for Main panel box to be replace - thank goodness some one home other wise I would have came home with no power - SePac had no idea that SMUD was coming (No communication?) when I called them. Now that no one ever contacted me nor tell me a safe way to bolt down the panels without guarantee no leakage - I cancel. NOW they REFUSE to refund me my deposit of $2K - They evaluated the situation but didn't do their homework before asking for a deposit - This looks like a company error but making a single women pay for their mistake and lack of communication.

The contractors neglected to do required structural load calculations for snow load. At the time, I had been told the design was far above code requirements and "built like a tank". On May 18, 2017, I filed complaints against Michael Sheridan @ Sepac Energy with the Contractors State License Board and with the Board for Professional Engineers. Their civil engineer, Roger L.
