If you have a solar powered pump, it will only pump the water around when the sun is shining and heating the water. When the sun goes down and there isn't any more heat being put in the water, no more pump.
Usta be we'd sail into Black Manele bay on Lanai and wash the boat down with hot water. The water came from a tank about a half mile up the hill and the pipe was just laid on top of the ground. Nice HOT water by the time it got down to the harbor. Of course, with that system ALL you had was hot water but it would cool off at night. Once they built that hotel over at white Manele though there isn't any more hot water in the harbor.
I suppose you could take a few lengths of black garden hose and toss them up out in your yard somewhere in the sun. Attach one to the lower drain of your water heater and one to the upper end somewhere. Run water through the hose so there won't be an air lock and it should thermo-siphon the heated water back into your tank.
