I’ve just returned from Spain where I installed a new test setup for DustIQ at Plataforma Solar de Almeria (PSA). This solar research site is located in the Tabernas Desert, 30 km from Almeria and is a perfect location to challenge our DustIQ to a dusty environment.
Last week, I went to the PV Operations conference in Munich, organised by NewEnergyUpdate. Besides pleasant talks with attendees during the networking breaks, I had the opportunity to speak about the importance of irradiance and soiling measurements for utility solar plants.
Measuring dust and soiling ratio is a new field of science. There are many opinions about it, but there is no large history of data and experience in measurements. Although the spot measurement of DustIQ is very precise, it is wise to do interpretation and use common sense when extrapolating the measurement value to the whole PV plant, or a part of it, for decision making. The DustIQ measurement value is true, but the question is whether this value is representative for the whole PV park.
When I was in the middle of preparations for field tests of DustIQ, Solarplaza published the whitepaper ‘Soiling - origins, measurements, analysis & solutions’. A subject that is the focus of a large team of Kipp & Zonen colleagues at the moment, soiling. It’s nice to see that we are not the only ones researching this matter!
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.
In continuation of the launch of our unique RT1 Smart Rooftop Monitoring System at Intersolar Europe in Munich early 2017, we took the opportunity to exhibit and promote it at Intersolar India in December 2017.
The Future of Solar Power in India
The Jawaharlal Nehru National Solar Mission (JNNSM), an initiative of the Government of India and Indian State Governments, has targeted generating 100 GW of the country’s national power through solar sources by the year 2022.
That’s not a question: we need both! As a result of a fruitful co-operation, 3E and Kipp & Zonen present a joint white paper, indicating that satellite and pyranometer irradiance data can both co-exist and do even complement each other.
You may know that most of the PV panels in the world are manufactured in China. But something you may not know is that, according to official statistics, in 2016 China produced 57.7 GW of PV panels and the new generating capacity in China was 34.54 GW. The total capacity was 77.42 GW by the end of 2016. So you can imagine how fast the speed of development is, or you can call it explosive growth of PV power plants.
