Solar Energy Systems

There has never been a better time to go solar...

An investment in your home, your planet, and your future!

You may have heard a lot of talk about solar systems lately, and maybe you even have a neighbor or two with a solar system on their property. The fact is, solar panels are available at higher capacities and lower costs than at any other time in history. This makes now an excellent time to invest in a solar system from Jonas!
Our experienced system designer will assess your electrical usage and the unique characteristics of your property, and engineer a system that produces the maximum output for the most affordable price. We will make sure to maximize your investment with careful placement and choice of appropriate equipment. You might be amazed at how quickly your system can pay for itself!

Micro Inverter Technology

Our systems all feature micro inverter technology. Some solar systems utilize a large and expensive inverter that requires expensive low-voltage wiring and causes inefficiencies in your system. With our micro inverter systems, we can eliminate single points of failure, while increasing the efficiency of your system and lowering the installation costs.
What's more, using micro inverter technology allows us to add additional panels to your system at a later date for less cost and no added complexity or major system alterations. You will also be able to monitor your system's efficiency from anywhere in the world using just your web browser.

Professional Installs, Professional Parts

At Jonas, we take pride in our work. Your installation will be completed by professional installers that have received proper training. Your system will be engineered to perform at its peak for year-round production. We use only the best panels, inverters, and accessories that are available to the industry. You will be satisfied with your system, we guarantee it!
