When I was doing research on satellite derived irradiance data I spoke to more than just my colleagues at Kipp & Zonen and providers of satellite data; I also contacted other stakeholders in the solar energy industry. And that is when I came across different myths that were going around in the industry. Here’s my list of the top myths on the subject of satellite and pyranometer measurements that I would like to dispel.
People frequently ask us questions related to the uncertainties of pyranometer measurements. As the sales & service engineer at the head office I have answered these questions coming from all over the world, especially from customers in renewable energy. I have summed it up in a short overview.
Earlier this year we opened a competition to find the oldest pyranometer still operational in the field. Now that the competition has closed and we have sorted through all the applications we can announce the winner is a CM5 from 1971. You probably want to know more, just like me, about the history of this pyranometer that originally started measuring in Canada and ended up in Germany for a second life.
