Production is 55% of guaranteed kwh
I have a signed guarantee to meet 90% of 15,210watts (13,689 watts). At my anniversary date I sent them my electric bill bills and usage readings and they replied that we should review this in August, which was a little sketchy, but I thought it might be more fair to let them get some summer months of sunlight. So now I got my August invoice and sent it to them along with all the others over a month ago and have not heard anything back through email or any voicemails, just completely ghosted a customer because their guarantee was not met...

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.
