An australian solar study concluded
That the most efficient use of solar radiation conversion to useful human energy is to convert the radiation to heat and store the heat for use later. Therefore, the most useful conversion is to heat water and store the hot water for use later.
The most efficient for them was storing heat in the hot water tank which was highly insulated, for use in showering and washing at a later time, or at any time. Obviously heated during the day, matching with usage. now I shower at night to go to bed clean versus going to bed dirty, and transfering that to the sheets. . . others shower in the morning. . .
This strategy makes the most useful sense to me, since there is a high conversion ratio from radiation to storable heat.
The information is searchable, and your decisions are yours. (I don't have a pool, but would use solar heating to maintain the heat when direct radiation is not available
