How does that work with Solar Enregy?
THE SOLAR ABSORBER COLLECTS SUN ENERGY AND PASSES THE ENERGY ON TO A LIQUID INSIDE THE ABSORBER. THE LIQUID IS PASSED (PUMPED) THROUGH PIPING INTO A HEAT EXCHANGER,  WHICH IS PART OF A STORAGE UNIT (LIKE A SOLAR STORAGE TANK) AND PASSES THE ENERGY INTO THE POTABLE WATER SO THAT IT GETS WARM. 
Sunlight travels in 8 min. from the sun to the Earth and transports Energy in form of light (PHOTONS) and RADIANT ENERGY (ULTRA RED AND ULTRA VIOLET)

What does a YeS - solar system do ?
It can provide up to 70%  Free Domestic Hot Water (DHW) year round and up to 30% free supplemental heating or 30% off the cooling bill - sound good?

Will a YeS--solar system recover the cost ?
                At the fuel costs before Hurrican Katrina,

Residential Solar Systems for DHW achieve a break-even potential in less then 15 yrs.(moderate DHW usage) 10 yrs. (high DHW usage).
Typical System lifespans of at least 20 yrs. -- it pays to use Solar systems.

4-5 person household (high hot water usage) 10 yrs or less, typical.
Add in the Supplemental heating in winter and break-even potential in less then 10 yrs. (high hot water usage 7 yrs and less).
And now we can offer cooling, too. Absorption cooling - chiller conditioning with Solar.
Thermal Solar Systems do work best if you use plenty of hot water
