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.
Energy Composition for 6 months
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.
