Solar panels look simple flat, silent rectangles sitting on rooftops but under the glass is a surprisingly complex piece of engineering. Different panel sizes, cell layouts, and electrical characteristics all affect how much power you get and how that power is distributed throughout your system. And no, the panels don’t “store sunshine” (we wish), but […]

I have been meaning to write this for quite some time. I think many people will find it useful because there is a huge amount of misconception about what wind turbines can do and what they can’t do, so before you go wasting your money or setting yourself up for disappointment please give this a […]
We are being misled by the Minister of Energy, Eskom and the entire IPP program. Today we were informed that a 100 megawatt plant cost them 62 billion rand. Sadly, this is probably true. BUT. The reason why it cost so much money is due to the very people that are now complaining about the cost […]
