Please note in order to make sense of this blog post you need to read Part 1: Solar energy as an alternative to centralized power systems.
As we’re heading into winter South Africa’s continued loadshedding will have an even greater affect at home and work as people spend more time indoors requiring amongst other things more lighting as well as heating. We are blessed with abundant sunny days making solar very reliable without the need for a lot of backup storage in the form of batteries. If you are considering going off the grid, whether partially or fully, my previous post will give you a basic understanding of how solar energy works and the components of the system. In this post, I show you how to calculate your energy requirements, as well as choose an inverter, batteries and solar panels to suit your needs.
