Kilo Hollow installed a residential rooftop solar system only for us via EnergySage as the conduit. The folks at Kilo Hollow, especially their president, is extremely passionate about the solar energy sector and it was evident how much pride they have in their process and product. From the get-go, the company was very responsive to all questions and communicative of status of various steps throughout the engineering and build cycle. They were happy to customize the quote and end product for my desires. Once the build was finally underway - they took extra time during the install to ensure a quality finish and were sensitive to the cosmetic considerations of the panel installed locations. Everyone brought onto the job site were very courteous pros at their respective jobs.

The Kilo Hollow sales team was very thorough with the design of my custom solar array. They took their time and paid attention to the minute details and sizing. They were also very responsive to my calls and emails. I couldn't have asked for better communications. I highly recommend this company to anyone in Virginia who is looking for a solar installation!

This past winter in VA was absolutely BRUTAL! My home lost power for almost an entire week during the dead of winter due to the massive snow fall we received. After that experience, I swore I’d never be without power again. So I started researching whole house generators and stumbled across Kilo Hollow. I reached out and requested a quote and literally within the hour I had a quote sitting in my email! I was blown away by how quickly they responded. Because of how fast they were and the price was right, I decided to buy the generator and have it installed by them. The installation was quick and easy. I highly recommend Kilo Hollow for generators if you are searching around for one!!!

The sales and storage design team Kilo Hollow we’re great. We had a lot of questions, they answered all of them and were very helpful. We decided to install a smaller solar array on the ground. We’re happy we used Kilo Hollow. -Daniel

I started my solar journey by calling two local companies. Then I joined EnergySage. I had site visits from three companies including Kilo Hollow Energy and chatted with several other companies online. I had done exhaustive research and knew exactly what I wanted. Kilo Hollow Energy was the only company that wasn't limited by having to use specific product brands. They were able to deliver exactly what I wanted. They also had the most reasonable price. Kilo Hollow Energy is a family owned business and they treat their customers like part of their family. I recommend them to everyone that I talk to that is considering solar.

I decided to expand my solar collection and add a ground array to my property. I have panels on my roof now, but wanted something a bit bigger. Kilo Hollow delivered and installed in a smooth and effortless way!! I couldn’t have asked for better communication or a better installation process.

Kudos to William of Kilo Hollow Energy. William patiently answered all of my questions and willingly evaluated multiple scenarios I presented. He helped me understand the full cost, of financing and if going solar was profitable in my particular situation, when that would be, and how that would look. He was honest and forthright, in spite of the fact he might not get a sale. He continued to answer questions and send me information after I decided to wait to go solar. I am so impressed with his helpfulness, that when I decide to go the solar route, I will definitely choose to work with him and his company. He is a man of integrity in this weary world!
