Living out a little ways, we frequently have power outages do to winter storms, for the most part this is not a nuance, we heat with wood for the most part, and kerosene and candles take care of the lighting needs. The most frustrating part is not having water, I keep ~30 gallons or more in gallon jugs for this reason. My wife wanted to do something to have running water for these occasions.
I came up with the following solution:
- HarborFreight 45w panel (on sale + 15% coupon)
- 12v deep cycle RV battery
- 12v RV water pump
- Two 55g drums
- Misc. plumbing and wiring
This provides us with backup water during power outages, the flow is limited but you can wash hands, cook and flush the toilets that should make everyone a little happier.
This year is phase one as described above, there are some limitations as in the system does not start on it's own, (flip the switch and open the valve) and the tanks are manually refilled with a hose from the hose bib in the pump house (the same one that the 12v pump is attached to).
Next year I plan to add couple more 55g drums and automate the refill with a trickle fill through a Hudson valve or similar to keep the tanks from over filling. In addition, I plan to hard plumb the 12v pump into the system, and possibly add a relay to engage the system when the grid power is out.
Next weekend I hope to get a couple of photos of the system.
I have a question how sturdy are the HF racks for the solar panels? They are mounted to the roof of the pump house, so the panels have a steep slope my concern is wind and snow load, the panels are not supported above the mid point, and the attachment to the rack is not that secure in my view. Does anyone have any suggestions?
