Demo King

Demo King is here to facilitate you with all your residential solar needs. We can provide home solar installation and maintenance to all your needs, we have it all. Either you want on-grid that are connected to the grid and offset your home’s electricity usage, grid-connected photovoltaic solar structures with battery storage to light your residence during a power outage, or off-grid solar processes that work independently of the grid and provide continuous electricity to your household.
It’s easy to find a solar installer who’ll do the job for you, but how can you tell if they’re right for your needs? Here’s the thing: most residential solar Systems Installation Services do what they do because they are in it for the money. They will be happy to sell you a system that works well enough and saves you money, but without a lot of attention to detail or quality control. They also won’t go out of their way to make sure that your system is installed correctly, which can lead to problems down the line.

Affordable Price

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.

Its been an amazing experience we had with Demo King for our solar panels system installation! From the initial call with the Sales Rep till the installation, everyone was highly responsive & professional. The equipment they have provided was excellent. I would recommend going solar with Demo King as they are the best in the market.
