IEA: World reaches 2.2TW of cumulative installed
The world reached 2.2TW of cumulative installed solar capacity in 2024, with China alone accounting for 1TW of total operating capacity.
Solar photovoltaic (on-grid) electricity installed capacity, measured in gigawatts. IRENA (2025) – processed by Our World in Data The renewable power capacity data represents the maximum net generating capacity of power plants and other installations that use renewable energy sources to produce electricity.
Solar PV will account for 345.5 GW, bringing the total solar capacity to 1.42 TW by the end of last year. The growth in renewable energy is not happening evenly across the globe, with many developing countries being left behind in the transition.
According to the STEPS scenario, global solar module production capacity will reach 1,546 GW by 2035, while under the APS scenario, capacity will increase to 1,695 GW. In 2023, global production capacity is 1,115 GW.
Every day, the Earth gets about 174 petawatts of solar energy. By 2050, solar energy is expected to provide half (50%) of the world's electricity. The solar panel recycling industry will be worth $2.7 billion by 2030. The typical cost for a home solar system is between $10,290 and $20,580. Solar panels can help cut household energy bills by 20-50%.
The world reached 2.2TW of cumulative installed solar capacity in 2024, with China alone accounting for 1TW of total operating capacity.
According to the International Energy Agency (IEA), global solar panel production capacity will exceed 1.5TW by 2035. Its latest report, Energy Technology Outlook 2024, covers the solar, wind
Solar PV manufacturing capacity and production by country and region, 2021-2027 - Chart and data by the International Energy Agency.
A single acre of solar panels typically costs between $150,000 and $300,000 to develop. This covers the cost for a 200-250 kW capacity system, including all hardware and installation.
PV Modules and Balance of System (BOS) PV modules typically comprise 60-72 cells arranged in a rectangular grid, laminated between transparent front and structural back surfaces.
The global PV cumulative capacity grew to 1.6 TW in 2023, up from 1.2 TW in 2022, with from 407.3 GW to 446 GW [1] of new PV systems commissioned – and in the order of an estimated 150 GW of
