Looks like someone wasted the whole summer instead of doing it early and not having to worry about it!

Agreed with the above!
Go to a toy shop and find a "solar kit".
It usually includes a photovoltaic cell, a little motor, a little fan or other similar gadgets.
As to heat the water, the equipment is a bit more expensive, since you need a solar captor at least 2m^2, a solid roof to fix it and a thermal exchanger.
