December 2019 delivered slightly more solar energy to our photovoltaic panels than the December average of the previous years. In the end, that means that the production rose above 2MWh for the whole year, delivering less than in 2018 but more than in 2016 and 2017.

Photovoltaic panels lose a bit of efficiency every year, although it seems that the degradation is less than I thought a few years ago. That is what the article “What Is the Lifespan of a Solar Panel?” (from 2014) tells me, and similar numbers can be found in more recent postings on several forums about the subject.

That means that all in all, we’re happy with a yield of over 2MWh for a single year. Our installation is now running for a full decade, so I was expecting worse numbers.

Could it be that climate change has an impact on the weather here in Belgium? I don’t think our solar energy numbers can be used to measure such an impact, if only because they are way too local to indicate more than local fluctuations.

Looking at the situation in Australia, however, makes it clear that the effects of global climate change are becoming visible: extreme draught combined with extreme temperatures over a longer period result in horrifying fires. That, in my eyes, is a chilling illustration of the prevision¬† of scientists that “extremes” (such as high – or low – temperatures, heavy rainfall, etc.) will become more “extreme” and last longer as the planet warms up…
