|How is the economy?|
As technology is matured and production is streamlined, the capital cost of a solar water system has tremendously dropped. An REG family hot water system costs about $3,590. The money it generates for you is about $550 annually. So the capital investment could be recovered in 5 years (with the government rebates) even based on the current energy price! If energy price further goes up (surely it will), the pay-back rate will be higher!
Environmental while saving money! Why not!
