How to design a solar system to meet your needs, Part 2

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.

Take charge of your power needs, Part 1: Solar Energy as an alternative to centralized energy systems

How to design a solar system

Currently, in South Africa the centralized electrical grid is unstable and has led to the current reality of regular power outages; subsequently many people are considering solar as an alternative. 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. These equations shift depending on where you live, however even countries like Germany which is not as blessed with as much sunshine, place a large emphasis on solar technology as part of their energy solution. Whether you live connected to the electrical services grid, or off-the-grid, there are compelling reasons to use alternative sources of energy.

This post will give you a basic understanding of how solar energy works and the components of the system. If you have no experience in electrical energy at all it may seem a little daunting, however the math is really simple and with a little practice it’s as easy as ABC.
