I thought I’d start off by explaining a couple of simple points about how solar panels work, hopefully clearing up a couple of general misconceptions about solar.
1. Is there enough sunlight in Victoria to make solar panels work?
I guess it depends on what your expectations are but generally, YES there is plenty of sunlight in Victoria to make solar work. If you compare the amount of solar radiation we get here, to say, Germany – the worlds leader in solar power installations, we get around 30-40% more sunlight.
2. Isn’t it too cold here for solar power here?
Photovoltaic solar panels produce electricity from light, not heat. The photovoltaic material in the solar panel (normally silicon) tuns the light energy into electrical energy, the more sunlight the better the performance of your solar system. In fact you will find that as it gets hotter, the output from your solar system will drop off slightly, this depends on your solar panels temperature coefficient, but I will talk in more detail about this in a future post.
3. I don’t have a north facing roof, it’s not worth going solar.
This isn’t necessarily the case. Yes, a north facing roof is ideal for optimum performance, but you will find that even going around to an east or west orientation will generally only lose you around 15% compared to an optimum pitched north facing roof. There may even be options to split your system across a couple of different orientation rooves, if half your panels are north and half are west, you may end up with only a 7% loss over the whole system, which normally isn’t too bad. The Tindo Karra solar panels tend to be particularly suited to these scenarios, the embedded micro-inverter gives your system more flexibility when positioning panels, allowing you to split them up easily over a number of different rooves.
Green Energy Options aim to give you the information you need to make an informed decision. We can give you advice on panel positioning, estimates on electricity generation and money saved based on the panel positioning and let you decide if it’s going to be worth while going ahead.
Hope you enjoyed our first blog post, keep an eye out and we’ll try an keep you posted with useful tips and updates about solar power.
