Question: what is the largest area a generator can cover,and could you improve that figure

Mahnaz Rashedi answered on 4 Mar 2020:

The generators have different Kw rating from 7 Kw to 3200 kw. so if you think one house uses 3.5 kw per day for heating, cooking and lighting then with 7kw you can run 2 houses and by 3200kw you can provide electricity to nearly 900 houses.
there is always a way to make optimization to build a bigger generator.
