According to the latest data from the National Statistics Office, during 2020, the harvesting of renewable energy from grid-connected PV systems was estimated at 233.1 GWh, an increase of 20.5% over the previous year.

The stock of PV installations amounted to 29,339 of which 85.0% were installed in the region of Malta and 15.0% were in the Gozo and Comino region.

The NSO noted that the Northern Harbour and Western districts accounted for 37.6 per cent of the total stock of PV installations with 5,692 and 5,339 installations respectively.

When compared to 2019, the stock of PV installations increased by 6.8% per cent. The percentage increases were highest in the South Eastern district (7.5%) and lowest in the Gozo and Comino district (5.4%).

The domestic sector accounted for 93.6% of the total stock of PV installations, followed by the commercial and public sectors, accounting for 5.5 and 0.9 per cent respectively.

The NSO said that most increases in new PV installations resulted from the domestic sector. The Northern Harbour district had the highest stock of PV installations in the domestic sector.

The top 10 localities for the spread and intensity of domestic PV installations per 1,000 population were in the region/district of Gozo and Comino.

The NSO said that when analysing the results by district, the Gozo and Comino district had an average of 119 domestic installations per 1,000 population, followed by the Western and South Eastern districts at 80 and 63 installations respectively.

The lowest ratio was registered in the Northern Harbour district, with 31 installations per 1,000 population.

Production of energy from PVs: 2020 – Total kWp amounted to 184,563.7, an increase of 19.6% over 2019. The commercial sector amounted to 50.6 per cent of total kWp, followed by 46.4 and 2.9 per cent in the domestic and public sectors respectively, the NSO said.

The peak power rating of an average PV system in the domestic sector stood at 3.1 kWp, whereas that for the commercial and public sectors amounted to 57.7 and 20.6 kWp respectively.

When compared to the situation in 2019, generation of energy from grid-connected PVs increased by 20.5%, the NSO said, totalling an estimated value of 233.1 GWh. Most energy was generated in the South Eastern and Northern Harbour districts at 20.8 and 17.3% of the total GWh respectively.

The NSO noted that increases were highest in the Northern district (28.4%) and lowest in the Gozo and Comino district (9.6%).
