@offgrid,
sorry, cant help. Were in the US and weve only got several small solar panels for fencing controllers and several small applications in the farm.(lights and topping up batteries for power tools and a series of stirrers for our diesel refining).
Many of the Amish around us (They are ALL off the grid) use compressor powered airmotors for heavy amp drawing tools and certain compressors. They stock up the airpressure by using wind power and gas backup for heavy draws (Many Amish run carpentry shops with three of four big saws going simultaneously)
The Amish use a lot of water drive by hooking up overshot wjeels to the outlets of their water ponds.
The ponds themselves require a lot of maintenance because they fill in rather quickly and that affect the driving force.
My solar packs require periodiv=c cleaning because they drop in efficiency as they get covered with dust and dirt .(The worst time is during planting )
Stumble It!
