Where I live, the major consumer of power is cooling. I want to build an underground pool, that each day, during solar peak, I use the excess energy to freeze the water. Then during the evening, use that ice block to cool my house - with only grid power (or battery) required to pump the coolant. It seems like this would be a much cheaper solution than tesla power packs, but doesn’t appear that I can buy this system off the shelf.
- maxerickson 2y agoFor small residential, it's probably hard to compete with the capital cost of just running the AC in the afternoon (no additional cost). If the house has any insulation at all the heat gain once the sun isn't participating won't be too bad.
