Cavin and his team did a fantastic job installing our panels. Everyone at Sandbox solar was very attentive and helpful to work with! We've had the panels up for a couple weeks now and they seem to be working great!

Sandbox Solar installed a 16 panel 6 KW system on our home in April 2024. We found them through a City of Northglenn solar coop. They were excellent in providing a few different system designs, helping me understand the technology and answering all my questions (I am demanding in that regard). The installation itself went smoothly and professionally, the finished system looks great and sailed through city inspections and Xcel approvals. Efa was very helpful in guiding us through the entire process. I cannot recommend Solar Sandbox strongly enough. Thanks for your excellent work!

Awesome team! From Justin (sales) to Efa (ops) to Charles and team (installation) to Dan and Ryan (eletrical), Sandbox provided excellent service in the whole solar process. I'm happy with how the process was smooth and how their service was very attentive to my needs, especially when I probably asked the same question twice or more. The team was patient with me. Thank you and awesome work!!

We just had solar panels installed on our third home and the crew from Sandbox Solar did a wonderful job. The panels blend right into our black roof and the crew took the time to paint the conduit to match our house colors so it's basically invisible as well. The installation crew which included Charles Groning & Cavin were very polite and professional and they did all the work in one day and did a great job of cleaning up everything so you'd have never known they were there. I'm very satisfied with our installation and with the staff I've dealt with from Sandbox Solar.

Can't say enough positive things about Sandbox. We had a dispute over required repairs to be made by out nation-wide solar company. Sandbox stepped in, negotiated with the national company and did all the repairs for a small fraction of what the national company said it would cost. The repairs were efficiently done and we saved thousands. Sandbox went way out of their way to help. Thank you!

It was a great experience working with Sandbox Solar to get solar panels installed. Justin was very helpful navigating the sales and logistics of purchasing and contracting the work. Efa was very helpful in getting our project started earlier than expected. Charles and his crew did a fantastic job when it came to installing the solar panels. They were all very professional, and we really appreciated working with them.

WHY is Solar Appraisal important

Owning your home solar system provides monthly energy savings for 25+ years, automatically increasing your home’s value when you sell!

  • Whether you’ve purchased your solar system with cash or are paying off a loan over time, a home solar installation is a tangible asset that will provide significant value to your home.
  • However, home solar installations leased or purchased through a Power Purchase Agreement (PPA) do not give value to your home. Instead, they make the selling process more difficult because a 3rd party owns them, and the solar system must be transferred to the new homeowner with that agreement intact.
  • To receive the most value from your solar panels when selling, get a professional home solar appraisal from a reputable solar contractor like Sandbox Solar.
  • Don’t miss out on the price you deserve! — Contact Us
