Last year I bulit my own solar water heating system I have saved aproximately $1000 this past year on energy costs. Today it was sunny on the north shore of lake superior and about minus 10 c outside my system made 102f degree hot water from 0930 this morning until about 1600 this afternoon. This brought up my 40 gallon storage tabk up to 44 degrees c.
I thought there was a carbon calculator on this website but have not found it yet, can somone show me where to get a calculator.
