Solar PV is still rewriting the growth curve, with global additions rising 25.9% in 2023 and pushing cumulative capacity to 387.8 GW by year end. At the same time, costs have been falling fast, with module prices dropping from about $1.00/W in 2010 to about $0.11/W by 2023. This mix of accelerating deployment and shrinking hardware costs is exactly where the most surprising gaps show up across regions, from China’s 216 GW added to Germany’s 84 GW in operation.
