I have entertained installing solar for quite sometime during which I contacted Tesla and Sunrun. Tesla has a cookie cutter system design and if you want to customize it to your needs, be prepared for a substantial increase in cost. Evoultion solar was recommended by a friend who had his system installed by them. I'm extremely satisfied with the professionalism, no salespeople tactics, from the beginning of the project to the end. They custom designed a system that fits my current and future needs; I currently have one EV and during the first meeting they inquired if I have future plans that alter my electric usage so they can incorporate in the system design. They ended up designing a 6.9kWh system to accommodate a second EV that i plan on purchasing this year. After signing the contract, they handled every aspect of the project timely and professionally including city permit, equipment delivery, installation, inspection and NEM application to PG&E. They did all that with a price lower than the competition. we are now enjoying our solar system producing 40-45 kWh daily. I highly recommend Evolution Solar, their lead team **** and Amer are outstanding..
