There is also solar thermal.

If you look at the process of making the solar cell wafers, you will realise its not

environmental friendly just the part you convert solar to electrical energy is. 

Until we make solar cells efficient to a level above 75% in converting energy and

we have batteries that can store massive amounts of power on a small size cell 

renewable power is only good for off grid and backup use not as a main source

of power.

Ultimately solar becomes cheaper the larger you consume, especially in areas with abundant solar power and abundant consumption dusing the day.

@Thuo.....my friend hopes to "do the maths" so that he can weigh options.

The challenge in the rural areas...KP has made it very expensive to
have power if you are not close to the transformer.

Therefore this calculation will help decide between the two.

Anybody able/willing to do the sizing? I can share the details privately.
