PARIS – Solar power has been the star of the clean-energy transition, delivering major benefits for the climate, the cost of living, and energy security. With an average annual growth rate of almost 30% over the last decade, the market for solar power has undergone a rapid transformation. What was once a heavily subsidized renewable-energy technology is now a readily available mainstream solution – whether one needs to power skyscrapers in large cities or deliver electricity to small businesses in rural areas.
Solar has become an increasingly attractive option for electricity producers and consumers alike. In 2023, additions to the world’s renewable power capacity grew by 50%, and most of that was solar PV. With supportive policies already in place in more than 130 countries, solar power looks set to continue playing its starring role for the rest of this decade. Compared with the previous five years, solar PV deployment through 2030 is expected to more than double in major economies such as the United States, China, the European Union, India, and Brazil.
Falling costs have been a key driver of this growth, with solar-panel prices declining by almost 50% in 2023. The combination of lower costs, scalable manufacturing, and quick installation means that solar PV is cheaper than new fossil-fuel power plants in most markets. Moreover, the benefits of solar can be amplified when paired with energy storage such as batteries or connected to larger, flexible systems via grids to deliver reliable power supplies.
Still, despite the unprecedented growth of solar power in recent years, the world needs to triple its renewable-energy capacity by 2030. At the United Nations Climate Change Conference in Dubai (COP28) last year, all countries agreed that meeting this goal is necessary to keep the 1.5º Celsius target for global warming within reach. The task for policymakers is to provide regulatory certainty for the private sector; ramp up investments in solar and other renewables, electricity storage, and grid infrastructure; cut red tape and remove administrative barriers; and improve access to finance, particularly for projects in emerging and developing economies.
