Europe celebrates its first European Solar Day

On 21 June, the longest and brightest day of the year, Europe celebrates its first European Solar Day and the role of solar energy in creating a sustainable and resilient future.

Within a few years, solar energy has evolved into the most affordable sustainable energy technology, with each solar panel saving 80-90% CO2 compared to average EU electricity.

On the occasion of the first #EuropeanSolarDay the new, Europe-wide number comes – 46 GW of new solar capacity was installed in 2022. SolarPower Europe’s latest Global Market Outlook for Solar Power 2023-2027 reveals the wider European region installed 46 GW of new solar capacity in 2022. It will power the needs of almost 14 million homes.

To celebrate the solar boom, APSTE together with over other 30 cross-sector organisations supports SolarPower Europe new initiative for launching the first-ever European Solar Day. Held on the summer solstice, or midsummer, the event unites individuals, organisations, and nations across Europe, showcasing the crucial role of solar power in achieving the energy transition.
