I have a well drilled and set up soon on my property where I plan to use completely off-grid (not tied to city power) solar array. Obviously I plan to optimize the power usage for everything that is going to be there. The well pump is one of those things.
So the well people recommend to install medium (40 gal) pressure tank with cycle stop valve (CSV) while I think I might be better off with a larger tank (80 gal) and a pressure switch (PS).
I understand that the CSV is good for the pump longevity with a continuous water usage (like showers), but I think a larger tank with PS is good for both - pump life & energy conservation (with considerable water usage). 4 people are going to live in 2 cabins on and off with each cabin having 1 kitchen sink, bathroom sink, toilet & shower. What do you, experts out there, think about it?
I am completely new to this whole thing, so I need guidance. Thank you!
EDIT: I guess I should have phrased the question simpler, like "what will use more energy CSV or PS in a well with the pressure tank setup?". That is the answer I am looking for the most. But nice to hear about alternatives as well.
