In reality our ESKOM supplied electricity , compared to the cost of solar solution sources such as photovoltaic Solar energy system or gas are still very cheap.
For this reason it is still difficult to justify a high cost of a solar solution in order to create the same power facilities as those offered by ESKOM. ( Although very cheap product come into the Market which create a false sense of reality)
Weneed to also include other realities such as:
One should use basic logic in order to consider converting to a photovoltaic solar solution:
Yes, its possible to start with a small solar solution , and build up an up to a complete big independent solar solution/system, without making any part of the system redundant while expanding, but this do need careful planning and correct product purchasing as first prize.
Please note: Hot water geysers are seen as a separate entity, as they make use of the heat of the sun to warm water circulating through specially designed heating panels.
Below is an example of a complete solar solutions(Demo Only)

Here is a scenario of common household power usage and the relevant costs to run such a system with photovoltaic solar power solution:
To provide lighting and use of common household appliances:
If we add fridge and freezer to the equation, which must run 24/7 will add cost in the form of at least 4 more 250W panels and 4 more 180A.h batteries.
Starting/planning a solar system solution for your home can be done in stages:
Let us say that we start with a solar system that will provide power for a TV, DVD, DSTV, a radio and cell chargers and say 10 x 15W lights:
In this first stage we will include a power inverter that will accommodate future needs as well.
The following components would all be added to those already installed in Stage 1
This should give you a good idea of the limitations and approach to design and costing your system.
