Hi, I'm helping a family member out with a project and would love some input and advise.
He has some off grid property and wants to put in a well and will build an insulated 8x8 pump house with a pressure tank and would like to be able to use it year round.
The roof will be larger to ensure enough space for the solar panels and to provide some dry storage underneath.
In the winter it can get down to -20c and would likely be used for 4-8 days a month in the winter.
3.4 annual average peak sun hours
The pressure tank would be drained when not in use during the winter and the shed will freeze as I cannot imagine a sensible/affordable way to keep it heated for weeks at a time with nobody there unless you leave a propane furnace on the entire time (assuming solar heat would require a truck load of batteries and solar panels, which doesn't seem practical or affordable!)
I know that once the well is drilled that will determine pump size and then also inverter size for a starting point.
My current thoughts are to install an RV furnace running on propane so when someone is there in the winter they can turn the furnace on, turn the pump on to fill the pressure tank and use the water for those few days. Would also have a small outdoor on demand hot water shower and some hose bibs for drinking water or to wash mud/dirt off people and equipment.
He would also love to use this building as a hub to bring a 15a circuit to some cabins/rv pads in the areas but maybe the cable requirements would make it more logical to just have independent solar setups at these locations.
I have some past minor experience with RV solar setups but would love any advise or input.
Default starting point would be some golf cart lead acid batteries with a MPPT charge controller so we can have some panels in series to ensure were getting enough voltage in the winter months. I think with the cold temps lead acid would be the way to go?
