Solar water heating systems work by capturing solar radiation through a collector and then use that energy to heat water for showering, laundry, dishwashing, etc.
A Solar hot water system can save up to 70% of costs to heat your domestic water which is the second highest user of energy in the home. At the same time you are reducing harmful CO2 greeenhouse gas emissions as well.
Federal and State tax incentives can significantly reduce the installation cost of solar systems
Systems can usually be retrofitted to work with your current hot water heater.
