Solar update…12 volt A/C?!

August 10, 2008

I thought it was worth amending my disparging comment about residential solar based on new information.

The AustinEV thread continues (and grows) about residential solar and 12 volt DC air conditioning.  DC A/C powered by solar would match peak generation (hot days) with the primary consumption (hot days).  Very interesting – why aren’t new home using this?!?

I think that residential solar is a bad fit for home given our current power loads, but would be excellent if we were more sustainable in our consumption (read: efficient).

I’ll go farther – I believe that houses should be switching to DC power instead of AC.  Most items in my house are DC and require converter bricks that waste power.  If we can have DC options for primary big consumers (A/C, refrigerator, water heater, dryer) than we could actually store power locally!
