I still feel solar panels makes more sense if you are building a new home due to the huge costs. That way the costs would be bundled in your home loan which will give you peace of mind

I also thought if this, but then you realise that the massive wind farm at JBay only generates 138MW at most, which is under 14% of the power that is load shedded in stage 1...
Another problem: "Real-life example: Big family home completely off the grid"
Big family home is no longer a realistic-life example with today's economy. Most of us use way less than R2000 electricity per month so large installations like these make no sense as an example and only put people off.
Has anyone assessed the implications of going off grid on
1. Sale of the property
2. Property values
3. Home owners insurance - structure
Just went onto solar geyser on Monday, next step might be to replace lightbulbs with LED, would it make much difference going from energy saver bulbs to led?
Lumens per watt is very close for cfl and led (in commercially available products), so not much advantage in going led, unless you go with less light output as well.Just went onto solar geyser on Monday, next step might be to replace lightbulbs with LED, would it make much difference going from energy saver bulbs to led?
I reckon it is much less expensive and complicated to get a generator with a source transfer switch. Trip your stove, geyser and pool pump, and off you go. All in with a 5KW genny for under R10k.
All these scenarios imply going completely off the grid, or with a grid connection.
Has anyone considered a partial system, that can run independent of the rest.
One of the big continual users of electricity in my house is lights. Anyone have an idea of the costs of setting up a parallel system running 12 V LEDs from a solar panel to provide some or all the lighting requirements of an "average" house?
This would negate the need for inverters, connection to the mains systems and have a much lower load requirement. And the need for continually turning off lights as you move through the house. I also think that this would be within reach of most average income families. And would probably add to the selling value of the property, without making it totally unaffordable because you need to recoup your investment.
