Andrew was spot on for the first and the second of my projects. Happy with both projects.

We were referred to Andrew more than three years ago. At the time, he said he would be happy to design a system for our house, but that it wouldn't be worthwhile because of our significant tree cover. When we began an addition and renovation project last year, we contacted him again, and he spent quite a bit of time with us, explaining how the system would function, how it would interact with Xcel's grid, and how to navigate the rebate and tax credit process. During and after construction, and a

Great service!

I strongly recommend contacting Andrew at Solar 4 Planet A to discuss your solar options. He came highly recommended from a trusted family member who worked with Andrew on a large project in Douglas County in 2023. Andrew was very patient (we had LOTS of questions) and provided several different options to my wife and I, each one with it's own advantages. Our home was built in 1925, and we were uncertain if the roof would support solar. But not only was the roof just fine (it turns out the panel

If you are looking at solar, my wife and I highly recommend getting a quote from Andrew Ehrnstein. We added solar to our house in 2023. Andrew was our consultant with Photon Brothers. He helped us design a system that met our current and even future electric power needs. I say future because we wanted to add a heat pump and EV vehicle at some point. Out of the three companies we looked at, we chose Andrew’s design and Photon Brothers as they had the lowest bid, the best warranties, and a design

Solar 4 Planet and Photon Brothers have been excellent to work with. plan and contract were clear and accommodating and installation was professional and quick. I highly recommend them especially for more challenging situations such as HOA restrictions and stone covered steel roofs.

It was really great working with Andrew on our PV system. He was very patient as we worked through several iterations of designs. Communication was on point and he was very professional and thorough throughout the process!

Andrew is an invaluable resource in helping people explore options with renewable energy and solar. He helped me talk through tesla powerwalls and different options and I'm so grateful for his insight!
