European Union has generated nearly 39 terawatt hours (TWh) of power from solar panels during June and July in 2021, accounting for 10 percent of total electricity produced in the region, Ember said in its report.
The 27 countries in the bloc had generated 10.9 TWh in 2018.
Total generation from solar panels lagged the electricity supply from coal, which stood at 14 percent for the region in June and July of 2021, the report said.
European Commission has proposed an overhaul of renewable energy rules, which decide how the bloc must increase the use of sources such as wind, solar and biomass energy produced from burning wood pellets or chips.
It has set an interim target for the EU to raise the share of such renewable energy to 40 percent of final consumption by 2030, up from roughly 20 percent in 2019.
“There are exciting green shoots in core solar markets where solar is taking off, but overall it is not growing fast enough,” Charles Moore, analyst for Ember, said.
Germany maintained the largest share of solar power production in the region, going from 11.5 TWh to 13.4 TWh, which accounted for 17 percent of overall electricity produced in the country during the summer period in 2021.
Spain had the largest growth for the summer period over four years, more than doubling from 3.1 TWh in 2018 to 6.4 TWh in 2021, which accounted for 16 percent of total electricity produced in the country in 2021.
The Netherlands showed the second largest growth over four years, nearly tripling production from solar panels to 3.2 TWh from 1.1 TWh in 2018, expanding the country’s total power share by 10 percent to 17 percent.
Italy was the third largest producer of energy from solar panels in 2021 but did not see substantial growth over the same period, going from 5.7 TWh to nearly 6 TWh.
Solar supply in the EU-27 rose by an average 14 TWh per year in 2019 and 2020 and is expected to do the same in 2021, but will need to over double to 30 TWh per year to meet 2030 climate targets.
