Record start for solar panels: most productive annual start in 20 years for Belgium

The first quarter of 2025 was the best ever in the field of solar radiation in the last twenty years. That calculated the energy company EnergyVision. And that is good news for owners of solar panels.
With only 1,367 hours of sunshine, everything added about 57 continuously days, 2024 became the third gloomy year since 1991. Only the 2000s and 1998 worked worse. Then we reached 1,366 and 1,284 hours of sunshine respectively.
Over the entire year 2024, the RMI noted only 917.2 kWh/m² of global solar radiation. That is the amount of solar energy that reaches the earth’s surface. That value was 120 kWh lower than average or the equivalent of the solar radiation of a spring month such as April.
But for the time being, that gloomy trend will not continue in 2025. The past three months have been a lot sunny than average. In March alone, the KMI recorded no fewer than 103.7 kWh/m² radiation, the best result since the start of the measurements in 1991. In the first quarter of no less than 166.4 kW/m², we enjoyed 41 percent more than in the same period last year and the best result ever since the entry of solar panels on Belgian roofs. However, 2024 was a leap year and the sun could shine one day longer in the first quarter than this year.
Energy company EnergyVision, which has tens of thousands of PV installations in families and companies in our country, aroused a record of solar energy in the first trimester with an average return of 128 kWh installed Kilowatt solar panels. When you compare this with 2024, this amounts to an increase in return by almost a quarter (24 percent).
The prospects for April also look good. The weather forecasts for the next two weeks look sunny. Again good news for owners of solar panels.
