    Q: What are clients of Diamond Certified solar companies saying about companies in Livermore, CA?
    A: Verified High Definition Solar Customer, 1 of 250
    "I like the fact they did both roofing and solar. They have to do them together, if you ever have looked into the solar, you will notice companies will recommend this. Because I'm very picky about what I have done to my home, they were tolerant of this fact and didn't mind me watching them closely. They had a good plan and are very organized." - Peter G.

    Verified Sierra Roofing & Solar Customer, 1 of 323
    "The job I selected was spray on all continuous film on a flat roof that wasn't a commercial building. I went walking on the roof to check out the job and noticed that some areas of the roof are hidden by some walls so near there, some areas hadn't been done. I called them to let them know and they immediately came over and corrected the problem. I'm satisfied. The courtesy they have for the customer and they explain everything pretty nicely. When they came back so I could sign the contract, I wanted a change, and they changed it so they were flexible." - John O.

    "They are a little pricier than most, but you only have to have it done once. They use up-to-code industry standards. I trust that they are going to do everything correct the first time. I think they are super friendly, and they always fit me into the schedule. I like that it will get done right the first time. They fixed many things that were done wrong in the past by other people as well. I use them all the time now. " - Jessica L.

    Q: What are some of the most popular brands that Diamond Certified solar companies use when working with Livermore residents?
    A: Diamond Certified solar companies use top-quality brands like Enphase Energy, Suntech, Solaria, JA Solar and Hanwha Q Cells.
    Q: What types of solar systems do solar companies offer?
    A: Solar companies typically offer two types of solar heating: active and passive. Active solar heating uses solar panels, collectors, and mechanical systems to convert sunlight into heat, which is then distributed throughout the house. This system can be used for space heating and water heating. Passive solar heating, on the other hand, involves designing and positioning a building to naturally collect and distribute solar heat, typically using materials that absorb and slowly release heat, like concrete or stone. Both types can significantly reduce energy costs and are environmentally friendly options.
