Before I write my review,…
Before I write my review, Everybody should beware and question why all 140-150+ reviews were all written 4 months ago? HMMM!!!
Anyways, If google allowed users to give no stars that's what this company deserves. This was a long awaited review that should've been written last October 2022 a little over 4-5 months or so, but I didn't have time to do it, and just remembered that I needed to do it to save other innocent customers the pain of getting ripped off and a headache. The whole process for my solar install from start (permit application) to finish (final inspection approval) took 8 months. Cause they had to come 4 different dates to do the installation till it was completed and 4-5 other times cause they failed all the city inspections and barely passed the final the 6th time. I can go on and put more about my negative experience with Diamond Solar and their staff, but google reviews only allows so many letters in the review. If you wanna see the full review go to yelp... Save yourself the headaches and stress, STAY AWAY !!! from Diamond Solar....

I have had my system up and running for about a month so far.  It's been great.  Working with Diamond Solar has been a very easy and enjoyable process.  The cost of installation was affordable, the time to design, permit and install the system was quite fast and everyone at Diamond Solar has been really helpful at every stage of the process.  For us going solar was not a hard decision.
