China expands solar rooftop program as grid struggles to keep up

China is expanding its solar rooftop program, with more homes, factories, and airports installing solar panels. This shift is part of the country's economic transition, as seen in the career change of former contractor Gao Shouguang, who now distributes solar panels in Chongqing. Homeowners can earn income by renting their rooftops for solar panel installation. The cost for a typical installation exceeds 100,000 yuan, but contracts with distributors provide annual payments. Solar companies benefit by selling the generated electricity to grid companies. Despite the growth in solar installations, the grid is struggling to keep up, leading to an increase in curtailment rates. This means that not all generated solar power is being utilized effectively.
