This is a very important Question, keeping it brief -
This is totally dependent on your needs and priorities and of course budget,
Firstly reduce your highest consuming electrical appliances, namely
- Geyser consumption at 40% convert this to alternative water heating, gas or heat pump or solar geyser, you will save 30-35% of your bill.
- Cooking on electricity, try to convert to gas cooking.
- Convert your lights to LED's.
- Run your swimming pool for a lesser total time period.
This reduces your bill immediately, but also reduces your 'load', this is what is used in calculating the size of your system.
The smaller the load the smaller the system you would require.
There are many very cheap products available, PLEASE ensure that you are getting proper materials and a proper installation team. The cheap route is the nasty route.
Install a medium sized solar array with battery backup that can be built on in time.
Alternatively, look to install a proper Lithium Battery backup System with a Proper Solar ready Inverter this is a foundation system that allows relief from load-shedding but is ready to accept panels when you are ready.
Or Purely for load-shedding you can look at one of our smaller inverter systems for essentials only.
PLEASE be aware of salesmen/women that promise you the world with a cheap quotation-this seems to be the trend the last few years, proper quality, lasting and safe solar installations are not cheap.
