The latest data from the research and data loggers for the energy inputs.
Energy composition: Solar PV, Solar thermal and Wood. Solar thermal brings in a LOT more kWhrs than Solar PV. The wood used so far this year translates into 1.26 cords of Douglas Fir.
In this graph, this documents the generated energy, not necessarily the energy used; the solar thermal gain in the summer time is partially used. From this graph we can easily see that trapping and storing the solar thermal would have been a wise investment, possibly with the addition of another 30 tubes, we may not have needed the gassification boiler. The $6500 put into the boiler could have gone into a large highly insulative storage medium, thus avoiding combustion.
