Is it getting hot in here?

I have found a heat pump that runs on DC for home use. Pretty interesting. Uses PWM for varying the compressor speed. They also offer an air-conditioner only version that I will be purchasing. The house currently has natural gas for heat that will have to do for a while. Ultimately solar heating will be introduced to the apartment.

I am ordering 2 - 38.8vdc 120watt 3.35amp solar panels to help charge the battery bank and for daytime desulfinating and maintenance cycles on the bank. Wired in parallel, the 38.8 should be decent for charging the 24v bank.

The best price I could find the panels for $264.00us. or $2.20 a watt.

Any suggestions or info on procuring a better value?

Thank you.
