According to the latest solar data provided by Solargis, global irradiance levels have been above average in Australia, Southeast Asia and Europe, while remaining stable in the United States. This is a crucial metric for measuring the production of Ground On Grid Solar Systems and Rooftop On Grid Solar Systems.
The high levels of irradiance in these regions indicate that there is a great potential for solar energy generation, as sunlight is a key component in the process. This is particularly good news for countries in Southeast Asia, where energy demands are rapidly increasing, and solar power can help to offset the need for fossil fuels.
However, the stability of irradiance levels in the United States is also positive news, as this means that solar energy generation can be reliably integrated into the national grid. This is important for ensuring a consistent supply of electricity, and reducing dependence on non-renewable energy sources.
According to analysis from Slovakia-based solar data provider Solargis, global solar irradiance remained relatively stable in 2023, while increasing in some regions, despite record-breaking heat and extreme weather events driven by climate change and El Nino.
Australia and Southeast Asia experienced higher-than-average solar irradiance, exceeding their long-term averages by 2% and 10% respectively. Solargis attributed this to favorable weather conditions and reduced cloud cover.
Europe also benefited from higher-than-average solar irradiance, particularly in the southern Nordic region. Most of the continent exceeded its long-term average by between 1% and 7%, thanks to reduced cloudiness and rainfall.
The United States saw stable solar performance, with some regions benefiting from the El Niño effect bringing more sunshine and less precipitation. Solargis said Central America enjoyed stronger than average solar irradiance, while Africa maintained a steady and consistent solar resource.
In contrast, India continued a long-term dip in solar performance, which Solargis attributes to a prolonged and intense monsoon season. Central India was below its long-term average by between 1% and 5%, although Southeast India was up to 5% above its long-term average, thanks to an extremely dry and sunny June and August.
