PV direct to water heat
I have an unused area in the middle of my heated basement that should be ideal for four IBC's. I also have a place near the house to put about 3KW in PV. I do not, at present, have the time or money to build a complete off-grid system with heat pumps.
Since most of my winter electric bill is for heating and DHW I was wondering about the possibilities of using the PV's to provide DHW and thermal storage in an IBC array. I have used IBC's for mineral oils at 100-110F without any problems.
Are there any known complications in using the DC output from the PV's to directly power a DHW tank or resistive elements?
This system would help me through the winter, by which time I will be in a better position to install an inverter for next summer's air conditioning.
Grid tie is not an option due to local policies.
