The installation of solar PV systems on homes, commercial buildings and industrial facilities are set to take off over the next five years, transforming the way electricity is generated and consumed, according to the latest renewable energy market forecast

A new report has predicted that the world’s total renewables-based power capacity will grow by 50 percent between 2019 and 2024, and this surge of 1200 gigawatts (GW), which is equal to the current total power capacity of the United States, will be driven by cost reductions and concerted government policy efforts.
The report, “Renewables 2019” by the International Energy Agency (IEA), further adds that solar PV will account for 60 percent of the rise. The share of renewables in global power generation is set to rise from 26 percent at present to 30 percent in 2024.
The installation of solar PV systems on homes, commercial buildings and industrial facilities are set to take off over the next five years, transforming the way electricity is generated and consumed, according to the latest renewable energy market forecast.
Distributed PV accounts for almost half of the growth in the overall solar PV market through 2024. Contrary to conventional wisdom, commercial and industrial applications rather than residential uses dominate distributed PV growth, accounting for three-quarters of new installations over the next five years. This is because economies of scale combined with better alignment of PV supply and electricity demand enable more self-consumption and bigger savings on electricity bills in the commercial and industrial sectors.
Still, the number of solar rooftop systems on homes is set to more than double to some 100 million by 2024, with the top markets on a per capita basis that year forecast to be Australia, Belgium, California, the Netherlands and Austria.
“As costs continue to fall, we have a growing incentive to ramp up the deployment of solar PV,” said Dr. Fatih Birol, the IEA’s Executive Director. The cost of generating electricity from distributed solar PV systems is already below retail electricity prices in most countries. The IEA forecasts that these costs will decline by a further 15 percent to 35 percent by 2024, making the technology more attractive and spurring adoption worldwide.
The expected growth predicted by the report will come after renewable capacity additions stalled last year for the first time in almost two decades. The renewed expansion, however, remains well below what is needed to meet global sustainable energy targets.
“Renewables are already the world’s second-largest source of electricity, but their deployment still needs to accelerate if we are to achieve long-term climate, air quality, and energy access goals,” said Dr. Birol.
Additionally, according to the report’s Accelerated Case, improving economics, policy support and more effective regulation could push distributed PV’s global installed capacity above 600 GW by 2024, almost double Japan’s total power capacity today. Yet this accelerated growth is still only 6 percent of distributed PV’s technical potential based on total available rooftop area.
Despite the rapid expansion of electric vehicles, renewable electricity only accounts for one-tenth of renewable energy consumption in transport in 2024. And the share of renewables in total transport fuel demand still remains below 5 percent. The Accelerated Case sees renewables in transport growing by an additional 20 percent through 2024 on the assumption of higher quota levels and enhanced policy support that opens new markets in aviation and marine transport.
