Pmax And NOCT: How Solar Panels Perform In The Heat

Pmax And NOCT - solar panels

Solar panel output reduces (slightly) as the temperature rises.

Optimal Orientation For Solar Panels In Australian Capitals: Directly North Isn’t Always Best

It is generally accepted the best direction to face solar panels to get the maximum possible output is directly north.  While this is not a bad direction, it is often possible to get a very small boost by having them face slightly away from due north.  Usually facing them a little to the east will improve output, but in some locations a small nudge to the west is best.

How To Power Through A Heatwave – In Comfort – On 100% Solar Energy

solar power and heatwaves

Is it possible to keep a family home comfortable in an extreme heatwave using only solar energy? Yes.

Last week I received a phone call from an ABC journalist. Unfortunately he didn’t want to invite me on Gruen to talk about the joys of solar advertising, or book Ronald & Tonto23 to perform on Mad As Hell. Rather, he’d been told that solar panels lose efficiency when it gets hot, and was keen to learn more. Specifically, he wondered how much solar panel efficiency would be lost if the temperature hit 45º during the heatwave – as forecast for the following day. [Read more…]
