In 2021, China installed 21.6 GW of residential PV, which accounted for nearly 40% of the total annual installation figure of 54.9 GW. Spool back to 2018, and the residential segment clocked in at a mere 3 GW – less than 7% of the total for the year. Vincent Shaw in Shanghai reports on how changing market priorities caused a spark that quickly became a fire.
Solar cell and module prices have increased by more than 40% over the last 18 months, driven by polysilicon prices. However, bid tariffs has remained lower than what is needed to mitigate the rise in module prices. The risk of lower returns is significant for 4.4 GW of projects that have been awarded over the past 18 months, with tariffs below INR 2.2 ($0.028)/kWh.
Renewable hardware that lasts longer and uses fewer materials could bolster recycling efforts and help to build an effective circular economy for solar and battery technologies, says the US National Renewable Energy Laboratory (NREL).
Alion Energy trackers thread the return-on-investment needle with productivity gains from white roofs and bifacial modules, while design aggressively maximizes module count.
