Sorry for the off-topic. I think if just 10% of the efforts were put on improving mini/micro/pico hydro electric generator rather than on solar systems, most of the rural areas will probably better off now with reliable power supply than relying solely on the intermittent solar power[1], [2].

In the developed world we're moving away from small hydro (bigger than this though) because of the effects it has on the environment. But in the developing world it would be good to see some advances!

The issue I always see on those is the pipe from the upstream reservoir to the generator gets knocked around and dislodged a lot when there's high water. It's less reliable and more maintenance intensive compared to solar it seems. Though it is more mechanical maintenance which is more friendly to more rural areas.

Everything is contextual. Hydro isn’t so good in rural southern NM where there is no running water at all for months on end.

Solar isn't being developed for rural communities though, so this is a bit of a non sequitur.

Rural installations are most common, by far. Maybe you mean they are being paid for by urban users?
