A brief look ahead at our natural building courses for 2018

Attend our natural building course and take the first step to a sustainable future by learning hands-on natural building skills. Learn a whole range of materials and techniques while exploring questions around sustainable living based in Peter McIntosh’s experience living off-grid since 1999.

Natural building courses in South Africa 2018

If you’re serious about building naturally and sustainably then you’ll know that each technique has pros and cons. That is why our natural building course is designed around the principles of understanding earth, how it works and does not work together. You will leave with the theoretical understanding and practical grounding of a range of techniques and materials, so that you are able to make the most appropriate decisions regarding materials and or sustainability once you are ready to begin your project.

This year, Peter will be hosting two CPD accredited courses at Jakkalskloof farm, in Swellendam. Continue reading

Take charge of your power needs, Part 2: How to design your own off-grid solar energy system

As the cost of power continues to rise and the cost of solar energy continues to drop, going off grid has never been easier. Learn how to calculate your energy requirements, as well as choose an inverter, batteries and solar panels to suit your needs.

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.

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

Being dependent on a central power source is not very powerful at all, especially as costs of centralized large-generation capacity gets ever more expensive, while the costs of solar energy continues to fall. 

How to design a solar system

Recently, 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.
