In reference to Mike Pare's article of Sat. may 23, 09. It seems to me that one important fact was forgotten. Did anyone bother to look at the financial payback of this project? Given the investment cost of $150,000 to $200,000 and savings of 16,000 KWH/year. Since the cost/KWH varies with amount of useage, lets use a high cost of 10 cents/KWH,and if we use a conservative investment cost of $160,000 to make the math simple, it will take 100 years to break even. This is also assuming zero maintenance and replacement costs and zero interest on the $160,000. Not a very good investment is it ????
