@Job 75%? That is asking for too much. Even 30% is highly acceptable for solar cells. The reason solar should be encouraged is so that people have something (power) to play around with without getting a huge discouraging bill at the end of the month. Main grid(read other sources) is not going to be cheap any time soon in Kenya. apparently the most innovative thing for Kenya Power is to increase tarrifs so as to improve on the 3B profit every year. That means when we get nuclear power we will have things like Fuel Disposal Levy, Radiation Protection Levy, Cooling adjustment Levy ...et.c

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.
