There’s no decarbonisation without data

WePower’s Kaspar Kaarlep offers a closer look at how we must use data to avert the worst of climate change.


New mounting system for rooftop PV, from Austria

The mounting structure relies on a 5.8m long support rail that does not lie on the roof but is connected directly to a purlin placed below with self-drilling support screws.

Sunday read: looming impacts of international trade disputes on polysilicon

Polysilicon capacity is unable to catch up with rapid capacity expansion in the mid and downstream segments, writes Corrine Lin, chief analyst for PV InfoLink. New polysilicon capacity requires big capex investment and a lead time of more than two years to complete construction and reach full operation. With unbalanced capacity between the upstream and downstream segments, polysilicon prices have been rising since the second half of 2020, with prices for mono-grade polysilicon surpassing CNY 200/kg (US$27.40) in June 2021, up more than 250% year on year.

Sunday read: Digesting Europe’s border tax proposal

The European Union’s proposed carbon border tax on imports of energy-intensive goods could push up prices of steel, aluminium and raw materials, which could add costs to the supply chain for solar PV installations. In the longer run, however, the border tax could also offer solar PV manufacturers new opportunities to source materials with a lower carbon footprint.
