That's perfect on a progressive tropical country and places. Though that would be costly, it will be cost-efficient in the long run. By the way, we also cater solar-driven systems but we rarely see interested clients for those projects probably because we have more renewable energy producing systems as alternatives.

mainly hydro power? which country if I may ask?

We have more hyrdro as an alternative, we also have air turbines and geothermal. But as of now, I think 60% of our energy sector comes from coal-powered plants and industrial plants.

It's from the Philippines and I'm in favor of nuclear energy which is not present in the country.

I assume solar would then especially make sense for everthingy off grid running on diesel gen set atm.. prices of solar pv and batteries should be much lower with break even after 1 to 2 years... please no nuclear energy.. not even talking about accidents and nuclear waste but of cost overruns.. new nuclear power plants produce electricity for around 15 US cents / kWh (12.5. cents power price + 2.5 cents for grid distribution) compared to 5 to 10 cents for PV, 5 cents for wind, etc..

Your solar idea sounds great to me
