@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. JK On 5/29/14, Thuo Wilson <lixton@gmail.com> wrote:

Proper Sizing of the required battery bank has to be done to prevent unwanted wastage. The number of solar panels is dictated by the size of the battery bank which further depends on the requirement.
You don't what a situation where the batteries are undercharged as this destroys them. Consider the right inverter size for your load as over-sizing results to overall system inefficiency if the load is way lower than the inverter output power.

Lastly solar power is expensive both installing and running as the cost per kwh is higher as compared to mains power for the same task. Unless there is no mains electricity or you what backup go for solar.
At last someone reasons like me on the last bit. Was tempted to install last year but "called myself for a special economic forum meeting". Finally i realised, Solar power isn't cheap at all BUT only environmental friendly. If you breakdown the cost + maintenance + lifetime of the same, its not worth it. Just a hype. I have done my maths and can attest to this.
