We recently had two Tesla Powerwall 3 units installed by Corda Solar in Danville, and wecouldn’t be happier with the entire experience! From start to finish, everything went seamlessly, with no surprises along the way. The quote process was straightforward, and the coordination with PG&E was handled flawlessly. A huge shoutout to Sara, Michael, Jennifer, and owner Nathan for their exceptional support, as well as the super cool installation crew who did an amazing job. The prompt email responses, thorough follow-up, and top-notch post-installation support truly set them apart. Highly recommend Corda Solar for anyone considering a Tesla Powerwall installation!
Great company to do business with. Nathan and his team of installers were very knowledgeable and answered any questions I had. They are local here in Danville Ca. and could not have done a better job on the installation. From the very first time I met with Sara (salesperson) to the completion of Solar panels/Powerwall install was exactly one month. Couldn't be happier. John S.
Absolutely cannot say enough good things about this crew. Professional, competitively priced, will install on Cal-pac roofing the proper way with clips. After sale support. I'm so happy with my system, I wish they worked in other industries so I could hire them for other things. 10/10 would absolutely use them again and wholeheartedly recommend them.
Corda Solar recently completed our residential solar project and they did a phenomenal job on what was a fairly complicated install. We had 26 panels installed in 4 separate modules, which was necessary due to our roof having many different pitches. They did a nice job tucking the conduit under the eaves to make it barely noticeable. They were very proactive with their scheduling and communication during the job, and completed it on time. The pricing was very competitive and they beat out the larger national companies I also had bid the project. Ultimately, these guys won my business by being engaging and friendly, and I'm always happier to support a local business where I feel like a real customer whose needs are important. Highly recommend Corda Solar!
After doing a ton of research, getting multiple quotes from those "find a solar installer" sites, we decided to work with Corda. We had had a positive experience buying a solar generator from them previously. Their quote was competitive and the interactions with them was very friendly, easy, and transparent.They installed the panels when they said they would and they are working great. We had our first -$80 power bill within 2 months. There have been a couple of kinks to work out and Nathan has been super-responsive. Amazing service.Best solar contractor in the Tri-Valley area!
