    Frequently Asked Questions for Solar in Alameda, CA
    Q: What are clients of Diamond Certified solar companies saying about companies in Alameda County, 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 Alameda County residents?
    A: Diamond Certified solar companies use top-quality brands like Yingli Solar, LG Solar, Panasonic Solar, Trina Solar and Enphase Energy.
    Q: What types of solar tracking systems do solar companies offer?
    A: Solar companies typically offer two types of solar tracking systems: single-axis and dual-axis. Single-axis trackers move your solar panels on one axis of movement, usually aligned with the path of the sun to maximize energy production. Dual-axis trackers, on the other hand, move on two axes, both vertically and horizontally, tracking the sun's path more accurately throughout the day and throughout the seasons. This leads to even higher energy production. Some companies may also offer passive and active tracking systems, with the former using a low-energy mechanism to follow the sun, and the latter using motors and gears driven by a controller.
