Getting Into Green Energy has never been easier!

The SOL 25 PLUS
Designed for either light commercial or residential use, each SOL 25 delivers up to 21,000 BTUs per day from 28 square feet! Installing these panels is simplified due to the extensive line of mounting accessories available. Built to last, Stiebel-Eltron leverages over 30 years in the solar thermal industry where experience has shown that using only the most durable materials is the only way to go.
 
Right now there is a federal tax credit that may allow you to deduct up to 30% of the cost of this technology as well as a similar program available from the state of Maryland. We urge you to begin the process now as in these uncertain financial times, no one can predict when these program will end.
 
One thing we are certain of, every month a utility bill will appear in the mailbox of every single home that uses their services. In today's world, knowing that energy costs can be unpredictable, it makes sound financial sense to reduce your dependence on outside energy costs every way we can.
 
There are three possibilities;
 
1.) Energy costs can go up.
2.) Energy costs can go down.
3.) Energy costs can stay the same.
 
Which option are you betting your future on?

 

Three SOL 25s attached to our house
On a typical winter day, these three panels will begin generating hot water, occasionally reaching temperatures in excess of 165 degrees, by noon time. Attached to our Stiebel-Eltron array is a meter that measures what is being delivered to our home. We invite you to stop by and see for yourself how this technology will help save you money.
