Honest & Transparent

Installation went really well. My Project Co-ordinator Fred communicated with me on weekly basis at every step to confirm I knew what's going on with my project and what was next. I've been very happy with my choice for solar installation.

Self-sustaining & better opportunity with the right installer

These guys have done a great job installing 34 Q Cell Solar panels on my rooftop. I was concerned about the roof so much & they gave me 15 years roof penetration warranty unlike any other installer. Also they are locals so its a great deal to have this project done by Demo king team

Recommend Demo King!

After completing the system's installation, it is now operational, and the utility bill has changed. Along with the overall amount of energy produced, the monitoring app displays when a portion of the panels are in the shade. Even after installing my system two years ago, Demo King Solar has done an excellent job of maintaining it.

Affordability

After receiving estimates from over ten different businesses, I discovered Demo King Solar. When it came to selecting my solar equipment, Aiden was able to offer me an open assessment and several excellent possibilities. He was able to provide me with the greatest system on the market at a very affordable price. He was able to complete the job on schedule since his initial estimate remained the same.
