He came in $20,000 lower than one bid and at least half that on another bid. He finished the job a week early and under budget.

Thanks Volt! I highly recommend this roofing and solar company. Buck and his team are great: very…read moreknowledgable, hard-working, and have amazing attention to detail. On top of that, they're just good down-to-earth people. We hired them last spring to re-roof our home, replace some rotted eaves and fascia and replace our old solar system (it was inefficient and malfunctioned quite a bit). We are very happy with what we got for the price we paid, it was a good value. It looks so much better than it did before and is consistently producing more energy. I feel like they helped us make the right decisions through the whole process, especially for system size to be able to keep our NEM1 status. The new roof looks great and works really well. I waited almost a year to write this review to make sure there wasn't any water intrusion during the winter storms - not a drop anywhere. They were in the mid-high range in pricing on the bids we got, but I'm happy we spent a little more went with them. Can a roof be sexy? Ours sure is. All in all, if you need a new roof or solar system or home battery, or all of the above, call Volt. They are a competent and professional group of local people who are really f**king good at what they do.

We have an older solar system that suddenly stopped generating. I had no idea who to call for a repair and took a chance with Diamond Solar Solutions after doing a quick online search for recommendations. Brad came out 3 days after my initial call and within a few moments diagnosed my problem. He found that the initial installer had failed to ziptie the connectors and wiring so that they would not sit in a puddle of water after it rained. I was so grateful for Brad's efficient and competent service. He practically ran to get his ladder and get right on the job realizing that time was money. He was thorough, personable, and patient explaining what he had found. Diamond Solar Solutions will be my 1st point of contact for any future solar issues. They were honest and straight forward. I highly recommend this company.

I was contacted by Spartan staff Diego Nuñez after responding to a link survey about adding solar…read more Spartan was the first company to contact me and made an appointment to speak to me via phone since I said I did not need an in person consultation. I was interested in adding panels to my existing older solar roof panels. My panels are working well, but I could use more power. Was also interested on behalf of my daughter who wanted extra panels after adding an EV and hot tub. After a couple of tel/cons with Diego, we determined in both our cases, it would not be worth adding additional panels because our True-ups were not high enough annually to warrant a system purchase. We had an extensive discussion about the fact that there are no more perks or discounts to install solar and things have just gotten more expensive over the last year, with loss of rebates, etc. Diego was very honest that in both of our cases, the cost of upgrading our mutual systems was not worth the money it would cost. I truly appreciated his honesty as he talked himself out of not one job but two. Highly recommend this company for both staff customer service in getting to me quickly, speaking to me extensively twice and Diego's honesty in being upfront about in our case, the bang just not being worth the buck. I actually felt like I could trust the staff and these days, this is important. Thank you, Spartan.

It wasn't even a system they had installed, but she still treated it like it mattered. Super knowledgeable, helpful, and easy to talk to.
