The electrical bills are climbing at 15% per year ... load shedding is a reality and will be for some time ... looking at who is being awarded contracts for a "greener" solution ... maybe investing in your own system might be a worth while option.

Another thing to consider ... EV's and chargers ... if the price of fuel increases at the current rate and ICE vehicle will not only be more expensive to buy ... but your fuel bill will kill you ... then there is services and maintenance to take into consideration ... it might still be cheaper than electricity ... unless you can produce your own electricity to charge your vehicle of offer the service to your neighbours ... like cellphones they predicated 900k sales ... but in fact it hit something like 135 million sales within a short period of time ... and I am sure the government will help by bumping up the petrol tax (money for cream on the scones)

Moms school bus is a good example where you could save big ... low daily mileage ... can be plugged in while not in use and then be used at night to power the house if you find the home battery is low ... considering what size of the vehicle battery (from 30kwh) in comparison to a backup house battery from (2.4 kwh)... you could probably run your house for a few days.

If you are smart ... charge your vehicle while at work ... then use it to power your house at night and probably the whole weekend ... just leave enough to get back to work ... buy a car with biggest battery even if it it doesnt fit your budget ... it might other cost saving benefits.

People are going to say ... but you need to buy a new battery after a couple years ... well you spend R300k on a entry level vehicle at the moment and pay it off over a 3-5 year period ... then replace it ... rather than replacing the battery just buy a new car with a brand new battery.
