Just thinking out loud for my own design ideas

I think you are correct on having a 40 gallon tank full of hot water on hot sunny days, but i think in the winter months or days when its very cloudy then I dont think the tank will be at sufficient temp. But if im just using the stored Collector water directly into the hot water line to the house, then that water will be much hotter and be enough for a long single use at the end of the afternoon, and will get recharged the following day. Ive got a couple days history now on the operation , and yesterday was 84 f. outside , very cloudy , and rained most of the day --- at 5 pm when i took my shower, I still got 100 f. for a 5-10 min. shower. WHen i finished with my shower, it was just starting to get cool . Today, we have full sun all day long on a 93 f. day so I expect the Collector water to be around 150 f. which will give me a longer shower because ill be diluting that temperature water with the cold faucet . This project works great for the single person as myself, but obviously for a family it wouldnt be sufficient.
