AtisSun installed a 3 panel closed loop back Schuco (German) system in the Fall of 2009. We now have a 105 Gallon Hot Water Tank in addition to our existing 90 Gallon Gas Hot Water Tank. 

Here is the breakdown of costs:

	Year 1
Cost Of system	$9,800.00
Federal Tax Credit (30%)	$2,940.00
State Grant (less 25% Fed tax)	$1,875.00
Credit Total	$4,815.00
Net Investment	$4,985.00
	49.13%
ROI	4.01%
Annual Savings Estimate	$200.00
Total Savings to Date	$200.00

Usage Data is much more difficult to compute (as we cook with Gas) - I have estimated the Hot Water savings at $200 per year.

However, we have made a lifestyle change with the hot water. We are using the dishwasher more and running it in the middle of the day. If you run the dishwasher at 2pm on a sunny day - the system has plently of time to generate additional hot water for the evening - like showers and baths. Setting the dishwasher on a delay is the best way to take advantage of the sun.

Even on the coldest days this past winter with temps in the 20's - as long as the sun is out - those panels got up to 140+ degrees. And when the sun was not out - our Gas Hot Water Heater kicked right in.

That is "Going Green and Saving Green".
