China has set a new record for monthly installed solar power capacity, with a staggering 93 gigawatts of solar panels installed in May. This achievement surpasses the country’s previous monthly high of 71 gigawatts, set in December, and is more than quadruple the capacity added during the same month last year. According to the National Energy Administration, this remarkable surge is attributed to developers rushing to complete projects ahead of new regulatory changes expected to significantly reduce renewable energy prices.
The record-breaking installations in May followed strong performances in April, bringing China’s total solar additions for the first five months of the year to 198 gigawatts. This averages out to more than 1 gigawatt per day, a monumental feat that underscores China’s commitment to renewable energy. Typically, China experiences a spike in solar installations in December, but this year, developers accelerated their activities in anticipation of policy changes. A new regulation that took effect on May 1 made it more challenging to connect rooftop solar systems to the grid, while another policy starting June 1 removed pricing protections that had guaranteed profits for solar projects.
The Chinese solar industry, however, is not without its challenges. Analysts predict that the new policies will moderate the pace of installations over the summer, increasing pressure on Chinese solar manufacturers. These manufacturers have been grappling with overcapacity and falling prices for over a year. All major Chinese solar equipment firms reported losses in the first quarter of 2025, citing weak prices and rising trade tensions following the return of US President Donald Trump to the White House.
The trade tensions between the US and China have been escalating, with both countries imposing tariffs on each other’s goods. Trump imposed broad tariffs on imports from over 90 countries, including China, in early April, prompting Beijing to retaliate. The two sides reached a tentative truce in Geneva on May 12, agreeing to a 90-day pause on further hikes and maintaining a 10% baseline tariff. However, tensions resurfaced earlier this month amid mutual accusations of violating the deal.
The China Photovoltaic Industry Association has called for urgent consolidation in the sector, warning that unchecked expansion and price wars are driving the industry into a “race to the bottom.” As the solar industry continues to evolve, it is essential for manufacturers and policymakers to work together to ensure a sustainable and profitable future for renewable energy. With China leading the charge in solar installations, the world is watching to see how the country will navigate the challenges and opportunities that come with this growth.
