Total installed costs for renewable power decreased by more than 10% for all technologies between 2023 and 2024, except for offshore wind, where. In 2024, between 554 GWdc and 602 GWdc of PV were added globally, bringing the cumulative installed capacity to 2. China continued to dominate the global market, representing ~60% of 2024 installs, up 52% y/y. For utility-scale projects especially, which require a good amount of capital, securing funding while minimising risk is essential to success.
