When hooked up to the grid, converting from electricity to heat for storage makes alot of sense (to me).
But I'm curious about your case: why not use the old-fashioned solar water panels to create hot water directly?

My non-grid connected solar cost about $1200, and was easy to DIY. No $1000 permit needed since it is not connected to the grid. No moving parts and almost no electronics. House now uses only 8-12 kWh a day.
