Yearly energy generation from PV panels rose by around 100 gigawatt hours since 2021

Yearly generation of energy from grid-connected Photovoltaics (PVs) rose by nearly 100 gigawatt hours (GWh) between 2021 and 2025, data published by the National Statistics Office (NSO) shows.

During 2021, the harvesting of renewable energy from grid-connected PV systems was estimated at 255.9 GWh, while in 2025, this number rose to 351.5 GWh.

The share of Malta’s renewables has been increasing. In 2024, Malta met 17.2 per cent of its total energy needs through renewable sources, while in 2014, renewables accounted for just under five per cent of Malta’s energy mix.

The NSO data also shows that the number of photovoltaic systems in Malta rose by 5,271 since 2021. A photovoltaic (PV) system is defined as a complete set of components for converting solar radiation into electricity by the photovoltaic process, including the array/s of photovoltaic modules, inverter/s and associated balance of system components.

In 2021, the stock of PV system installations stood at 30,972, and it rose to 36,243 in 2025.

Of the total number in 2025, 85.6 per cent were installed in the region of Malta and 14.4 per cent were in the Gozo and Comino region.

Most of this energy generated in 2025 was in the South Eastern and Northern Harbour districts at 22.9 per cent and 18.9 per cent of the total GWh respectively. Increases from 2024 were highest in the Northern Harbour district (12.1 per cent) and lowest in the Gozo and Comino district (4.6 per cent), the NSO said.

The peak power rating of an average PV system in the domestic sector stood at 3.5 kilowatt peak (kWp), whereas that for the commercial and public sectors amounted to 65.7 kWp and 20.9 kWp respectively. This shows an increase when compared to 2021, when the peak power rating of an average PV system in the domestic sector stood at 3.2 kWp, and in the commercial and public sectors amounted to 60.7 kWp and 18.2 kWp respectively.
