The dataset comprises measured PV power generation data and corresponding on-site weather data gathered from 60 grid-connected rooftop PV stations in Hong Kong over a three-year period.
The total installed capacity of installed rooftop PV for 2023 reached 2.9 GW from 314,507 units, surpassing the level of commissioned large-scale generation projects in 2023 (2.8 GW). Additionally, rooftop PV reached a major milestone in March 2023, surpassing 20 GW of total installed capacity across the country2.
Thanks to the unprecedented solar capacity growth in 2023, a record-breaking 473 GW of renewable power capacity was built worldwide – a 54% increase from 308 GW in 2022. The strong growth in 2023 brought the world closer to achieving the ambitious goal of tripling renewable capacity by 2030.
The report, developed with data provided by solar consultancy SunWiz, has also found that rooftop solar photovoltaic (PV) system installations reached 20 GW of total capacity across Australia in 2023. New South Wales broke the record for the highest annual installed capacity of any state, with 970 MW of new rooftop solar systems.
Almost three-quarters of all renewable capacity built in 2023 was solar. Wind additions also increased by a sizable 51% in 2023, accounting for another quarter of renewable capacity additions in 2023. After two years of slower growth, 2023 saw a new record for wind capacity additions, beating the previous record set in 2020.
Solar capacity additions surged 74% in 2023, reaching a record 346 GW annual additions. China was the key driver behind the acceleration but solar's phenomenal growth is spreading globally, with 28 countries installing over one gigawatt of new capacity in 2023.
Power generation from solar PV increased by a record 270 TWh in 2022, up by 26% on 2021. Solar PV accounted for 4.5% of total global electricity generation, and it remains the third largest renewable electricity technology behind hydropower and wind.
Rapid growth in the deployment of solar, wind, and bio energy in recent years has led to Italy producing over 41% of its electricity from renewable sources in 2025, and adding 7. 48 GW (7,480 MW ) capacity in 2024. Renewable energy developed rapidly in Italy between 2005 and 2023, nearly doubling, and provided the country with a means of diversifying from its historical dependency on imported fuels. Solar power accounted for around 17% of the total electric production in the country in 2025. The decision allows Italy to support new renewable electricity projects through. The European Commission has officially approved a significant state aid scheme for Italy, valued at 23 billion euros. This regularly updated guide provides an overview of how far. The European Commission announced that it has approved a €23 billion state aid program by Italy to support the deployment of renewable electricity generation, aimed at accelerating the country's energy transition and helping meet EU renewable energy targets. The program will support the.

Greece has entered 2025 with a renewable energy sector that is simultaneously thriving and troubled. Installed capacity has climbed to record levels, with solar photovoltaics and wind power providing a growing share of the country's electricity. From 2018 to 2022, solar capacity in the Mediterranean country grew from 2. The government's ambition to make Greece a. 2023 marked a historic milestone in Greece's clean energy production, with 57% of the energy mix being supplied by Renewable Energy Sources (wind and solar) and hydroelectric units, surpassing 25 TWh. The rapid development of Renewable Energy. HAEE is proud to announce the publication of the Greek Energy Market Report 2025, a comprehensive and valuable resource for energy professionals, policymakers, academics, researchers, and companies interested in the Greek energy sector. More than half of the electricity supply, specifically 54%, comes from fossil fuels, with natural gas being the main contributor at about 44%. Coal and oil contribute smaller portions, around 5% and 4%.
