Another large PV system in Ghana

Yes leaving a clear bottle of water in the sun has been tried, and should work fine, but some people do not bother.

Other options include a deep well with a hand pump, at the school. Very hard work for large volumes but fine for a few litres of drinking water.
One large farm near the river use the river water but treated with an electric ultraviolet water purifier, with chlorine tablets in reserve.

Those living near the centre of the village usually purchase drinking water from the shop. Flat rate of 10 cents per container that one person can carry.

Captured rain water is sometimes used, but has to come from cement tanks. Plastic tanks make the water taste so bad that cattle wont drink it, much less people.

I will have to try the rainwater collected in our IBC containers as I plan to form a reservoir using them in the future to supply drinking water via a sand filter with secondary UV treatment.

Newish IBCs are often very unsatisfactory for drinking water because the plastic imparts a most disgusting taste to the water. Not certain that a sand filter would remove this taste.
Older IBCs are often better as the taste seems to leach out in time.
Similar arguments apply to use of plastic garden hose for drinking water, with new hose a most unpleasant taste results unless the entire contents are run to waste before consuming water from the hose.

O/T trivia, I am at present removing the "plastic taste" from 200 meters of garden hose for a friend. The hose is coiled up on the bathroom floor, and the water supply to the WC flush is passed through the hose, thereby removing the nasty taste without using any extra water.
