SolarPower Europe’s 5-year global solar market outlook forecasts 800 GW additions to 1.3 TW total installed capacity by 2023. A total of 102.4 GW of solar power went on the grid around the world last year. That’s still 4% more than the 98.5 GW installed in 2017 and this is in comparison to two very high-growth years: 2017 and 2016, which had growth rates of around 30% and 50% respectively. The main reason for last year’s slower solar market growth was the contraction of the Chinese market, which, at 44.4 GW, shrunk by 16% compared to its record 52.8 GW in 2017. While other leading solar markets also shrank (India, Japan) or stagnated (US) for various reasons, many new and emerging as well as re-emerging markets more than compensated for this slower growth period of the tier 1 group.
In 2018, 11 countries installed more than 1 GW of solar; that’s two more compared to the nine GW-scale solar markets in 2017. SolarPower Europe’s Medium Scenario estimates that the number will significantly increase to 16 countries in 2019. Europe as a whole added 11.3 GW in 2018, a 21% increase over the 9.3 GW installed the year before mainly because of the EU’s binding national 2020 targets. In 2019, SolarPower Europe’s Medium Scenario sees demand surge by over 80% to 20.4 GW, and an 18% growth to 24.1 GW in 2020, which would be a new installation record, surpassing the 22.5 GW Europe added in 2011. On a global level, in its Medium Scenario, SolarPower Europe anticipates that around 128 GW of new PV capacity will be installed in 2019, which would translate into a 25% market growth.
This will lead to a cumulative installed capacity of 645 GW, which is about 4% higher than assumed in last year’s Global Market Outlook. The solar TW-level will most likely be exceeded in 2022. The 5-year Global Market Outlook expects that global solar power generation capacities will add nearly 800 GW and reach a total solar power generation capacity of 1.3 TW in 2023.
