@Urstill1,

You might consider this.I know of someone who installed it 2 years back and he showed KP the middle finger.

I'm looking at it from a different angle: Reliability

@ Urstill1

You cannot be helped unless you get some numbers coming your way...

Yes, it is possible to install a PV system which is capable of powering all your needs in that 5 bedroomed house including refrigerators, iron boxes, electric kettles, TV, and water pumps and any other domestic appliance.

To start with the residential houses electrical requirements differ from one developer to the next depending on taste...for example there are those five bedroomed houses in Runda which the owners have installed A/Cs in each and every bedroom including sitting room and apart from that they have instantaneous water heaters to each and every bathroom in each of the bedroom and there is also a hot water cylinder (geyser) as a back up and a separate undersink water heater in the kitchen..

A similar dwelling in Kahawa Sukari do not have the A/C (or probably has one in the sitting room), no geyser etc etc...

So you have to be specific on the appliances that you would wish to have in your house and that is where we start...

@urstill1

Is the house existing or you are planning to build one??

In case it is an existing one, give us the electrical services details and the available appliances.

In case it has not been built, below could be an optimised scenario....

I am going to assume the following:

1. That for every bedroom, you will have a bathroom.
2. That there will be an extra toilet/bathroom for day visitors.
3. That you don't have a servants quarter.
4. That the house will be a Bungalow

So here we go:

The electrical services in the house will be as follows:

1. Sitting room (Assume size 5m x 5m)

(i) 2No lighting points
(ii) 4No Socket outlets

2. Bedrooms

(i) 1No lighting point
(ii) 1No Socket outlet

3. Bathroom

(i) 1No Lighting point
(ii) 1No instantaneous water heater (shower)

4. Kitchen

(i) 1 No Lighting point
(ii) 3No Socket outlets
(iii) 1No Cooker outlet point
(iv) 1No Undersink water heater

5. Store

(i) 1No Lighting point
(ii) 1No Socket outlet

6. Appliances in the house

(i) 1No Refrigerator
(ii) 1No Microwave Unit
(iii)1No Electric kettle
(iv) 1No Iron box
(v) 1No 42" LCD/Plasma TV unit
(vi) 1No DVD player
(vii) 1No Music System
(viii)2No Personal computers
(ix) 1No Hot water cylinder (geyser)

7. Security Lights

(i) 4No lighting points

Before we go to the finer details could you confirm that the above information is consistent with your expectation...

Great! There are 3 2-roomed servant quarter detached from the main house. Apart from that, the rest are as corrected!
