Latin America and the Caribbean could grow their installed solar capacity by a factor of 40 by 2050, according to a new report by the International Renewable Energy Agency (IRENA). Annual investments exceeding $7 billion would see the region’s solar PV capacity rise from 7 gigawatts (GW) today, to more than 280 GW by mid-century. While solar energy remains the highest in Asia, North America and Europe, market growth is set to shift to other regions in the world.
By that time, solar PV would represent the second-largest power source behind wind, generating a quarter of the world’s power, “Future of Solar Photovoltaic” launched today at “Sun World 2019” in Lima finds. In total, global solar power capacity would rise from 480 GW in 2018 to over 8000 GW by 2050, growing by nearly 9 per cent every year.
If accompanied by sound policies, the transformation driven by renewables such as solar can bring substantial socioeconomic benefits, IRENA’s new report finds. The global solar industry has the potential to employ over 18 million people by 2050, four times more than the 4.4 million jobs today.
Over the last decade, installed capacity of off-grid solar PV has grown more than tenfold, from roughly 0.25 GW in 2008 to almost 3 GW in 2018 around the world. With its modular and flexible nature, solar PV technology can be adapted to a wide range of off-grid applications and to local conditions. Indeed, off-grid solar PV is a key technology for achieving universal electricity access, in line with the UN Sustainable Development Goals.
Similarly, the deployment of rooftop solar PV systems has increased extensively, which today makes solar PV in some markets more attractive than buying electricity from the grid. The competitiveness of distributed solar power is clearly raising deployment in large markets, including Brazil, China, Germany and Mexico.
Statistical highlights from the report:
Accelerating solar PV can cut energy-related CO2 emissions by 21 percent in 2050.
With over 50 percent of installed capacity in 2050, Asia (mostly China) would continue to dominate solar PV power, followed by North America (20%) and Europe (10%). The Latin American market would grow from 7 GW in 2018 to over 280 GW.
Annual solar PV investment would have to increase by 68 percent on average globally, from USD $114 billion in 2018 to USD $192 billion in 2050.
Global levelized cost of electricity (LCOE) for solar PV will continue to fall from an average of USD 85 cents per kilowatt-hour (kWh) in 2018 to between USD 5-14 cents per kWh by 2050. A recent solar and wind power auction in Colombia was awarded for an average electricity price of USD 27 cents per kWh.
Due to innovations, solar PV remains a fast-evolving industry. Floating PV is one of the most prominent examples with global cumulative installed capacity exceeding 1 GW in 2018. Battery storage and electric vehicles are key solutions to support the grid and manage high shares of solar PV as well as to guarantee the flexibility of the power system.
