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.

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…]

South Australia’s Rooftop Solar Now Meets Over 60% Of Electricity Demand At Times

On Sunday, rooftop solar provided 60% of all South Australian electricity demand in the middle of the day.  This makes SA the most solar powered state by far and puts it well past the point where we were told solar power would destroy the grid, cause your lamb roast to cost $100, and make your cows spin backwards.  It’s a big increase from last year when the highest figure I heard was 48%.  Sunday’s percentage was so high it was off the chart.  [Read more…]
