Isn't heating your warm water still very effective with solar energy? Also a low cost investment.

You put this all together, and if you are paying money for all the parts, then the heatpump water heater and solar panels are cheaper and easier to run.
That said, if the shit hits the fan, I can build a solar powered hot water heater with any metal I find lying around. You build a tank (out of anything that won't melt at 212F) then you have some tubing (black plastic tubing works all by itself in SW USA) and you place it on a heat absorbing surface in a box with a glass cover to keep heat from escaping.
They problems come when you try to add it to a pressurized system. Everything becomes a lot more complicated. And everything has to withstand the pressure and added pressure caused by any trapped steam.
I like the drain back solar hot water heater systems. But those require two pumps and controlling electronics.
What a great comment! Thanks for the insight.
That is true. Solar water heaters use a different tech that uses less power because the heat of the water rises and builds in the pipes. Super hot, scolding ive used it.
Solar power works. Just producing it is pollution.
