COVID-19 IMPACT

COVID-19 Disrupted Solar Thermal Collectors, Severely Reducing Market Growth Globally

The global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing higher-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden market growth reflected by the rise in CAGR is attributable to the market’s growth and demand returning to pre-pandemic levels.

 Major disturbances in the market for solar thermal collectors were caused by the COVID-19 pandemic, which led to a dramatic decrease in growth between 2020 and 2022. Global manufacturing was delayed, and supply chains were broken, therefore impacting the delivery of vital parts. Due to tight lockdown rules and sparse workforce availability, installation projects were postponed or canceled. Consumer spending on nonessential and capital-intensive energy systems fell, thereby lowering demand drastically. Production in China decreased by nearly 12%, therefore demonstrating the gravity of the effect. Logistical difficulties and legal limitations caused losses for both European and Asian markets as well. The market started recovering in 2023 as countries started to open, even amid these obstacles. Renewable energy investments have started once again, pointing to a slow return to prepandemic expansion patterns.
