As reported by China Energy News, 13 publicly traded companies in China announced 40 new solar manufacturing expansions in 2020, involving $31 billion investment. This has reinforced an existing trend since 2018 of vertical integration of the wafer, cell, and module parts of the supply chain – meaning that increasingly the same companies hold manufacturing for each part of the process, although this is less true for wafers. Going by incomplete statistics gathered by SOLARZOOM by December 1st, announcements during 2020 saw manufacturing capacity expanded by 60% during 2020, with 38 GW, 69 GW, and 69 GW added in wafer, cell, and modules in just Q4 respectively, bringing those totals to an incredible 217 GW, 291 GW, and 269 GW.…
