    ★★★★★

    Cobalt Power Systems was recommended to us by our roofing contractor to be installed in conjunction with our new roof. We are thrilled to now be offsetting the cost of our high PG&E bills with solar power and the installation was smooth from start to finish. Cobalt did an excellent job of communicating with us and any small glitches we encountered were easily remedied with a phone call. We would highly recommend the team at Cobalt to install your solar power system.

    We interviewed several companies but none of them would consider solar panels for our house because we had wood shake shingles. I'm SO glad Cobalt had the right team in place to make sure we could do solar panels on our roof. They were professional, delivered what they promised and never was there a time when I emailed/contacted the team and they didn't get back to me in less than a day. After working with a lot of contractors over the past year, I can say that Cobalt was the best to work with. They left out no details in their plans! We're very happy with the design (can't see from the front of the house) and more importantly the energy being saved.

    We have been thinking to install solar for sometime, but didn't do it concerning it's validation and issues along with roof maintenences. Our house was having a new roof late last year. We start shopping for solar, talked to number of people and we chose Cobalt because Jisang and the solar plan he presented to us. He is very professional, easy to reach and come to site to inpect before putting the plan together. Then he guide us through everysteps with his team to make sure we are well taken cared. From signing up to completely installed and functional, his team is there to handle everything. What a great experience we had and definitely recommend them wholeheartedly.

    I heard of Cobalt Power Systems from my roofer, a neighbor of mine, as well as from his sister. In my dealings with Cobalt, I experienced great communication, patience, and a team that was attune to my needs and my questions; it was overall an educational solution-oriented experience. Cobalt is a premier one stop shop with high attention to providing a personal touch.

    I just finished a third round of Solar PV installation with Cobalt Power Systems. Every time was impressive. In 2010, I installed a PV system of 40 SunPower panels. That went very well, and the system performed better than predicted. In 2016, I added 44 LG PV panels which brought my power production to cover 100% of my electric bill, which has been zero since 2016. Both installations went extremely well.
