Get an idea of 
1. Average KWH consumption per day = idea of no panels and battery requirements, size of inverter
2. What is maximum load at any time (without a meter need to calculate using appliance watt specs) = size of inverter
3. Average KWH consumption at night (winter = 16+ hours) = battery size
If you are going to jump in then consider more than the just loadshedding, look more at investing in reducing your need to use Eskom as little as possible. The big bucks are in what you don't pay to Eskom.  The returns on the investment is that money that you would pay to Eskom, that you would be paying back to yourself, and after 6/7 years will make a profit for you because the system will be paid off and that money goes directly into your bank account. A loadshedding solution works out to be a convenience but saves very little. Scrap together as much as you can in the beginning, and/or plan a schedule to upgrade to the final solution

https://app.opensolar.com/#/home allows you to build and test solar solutions, including shading issues - free account
You can provide me your location and your expected average KWH usage per day,  and I could build a energy profile for you
