So what about Solar Panels on a northern roof?

Last week we saw our back-garden neighbours having some building work done on their roof. There appeared to be some kinds of long poles or perhaps scaffolding (annoyingly we couldn’t see exactly what was happening). Talking to our next-door neighbour later it turned out that there were solar panels being fitted on the roof.

All this really surprised us as my engineer husband had looked into the issues about getting solar panels for your home and generating solar electricity and decided that our roof faced the wrong way – and here was a neighbour with a roof facing in an even less favourable direction than ours having panels fitted!  He had also though that living in the north meant that any systems would receive far less sun power than those further – it appears that this is so, but not significantly.

Global Dimming

It was in 1985 that a researcher called Atsumu Ohmura who was checking levels of recorded sunlight around Europe found that it appeared to be too dark relative to levels of sunshine recorded by scientists in the 1960s. He found that solar radiation levels hitting the Earth’s surface had gone down by more than 10% in 30 years. And yet, by the 1980s evidence that the Earth was getting hotter was indisputable, so the reduction of solar radiation did not fit in with this idea. [Read more...]
