The evolution of residential PV in China

China is the largest residential PV market in the world, and this trend is only expected to strengthen in the next few years. By July 2021, China’s cumulative installed residential PV capacity had reached more than 30 GW, with a total of 1.864 million residential units hosting solar PV systems. IHS Markit’s Holly Hu looks behind these impressive numbers.

Solar supply, demand, and a foreign policy shakeup

As the solar market enters the busy season in September and October, module utilization rates are reaching 70% to 85%. However, structural shortages remain in the supply chain, with polysilicon supply running short in the face of high demand, writes PV InfoLink analyst Amy Fang. Prices, which were expected to stabilize, rose again in the second half. High module prices will cast a shadow on demand in the fourth quarter, prompting module manufacturers to postpone delivery for some orders from the second half into next year.
