During 2023, the harvesting of renewable energy from grid-connected PV systems was estimated at 309.3 GWh, an increase of 6.7 per cent on the previous year, the NSO said Wednesday.

Stock of PVs: 2023

The stock of PV installations amounted to 33,818 of which 85.4 per cent were installed in the region of Malta and 14.6 per cent were in the Gozo and Comino region. The Northern Harbour and Western districts accounted for 37.5 per cent of the total stock of PV installations with 6,598 and 6,096 installations respectively. When compared to 2022, the stock of PV installations increased by 4.3 per cent. The percentage increases were highest in the Southern Harbour district (6.0 per cent) and lowest in the Gozo and Comino district (3.1 per cent) (Table 1, Map 1).

The domestic sector accounted for 93.4 per cent of the total stock of PV installations, followed by the commercial and public sectors, accounting for 5.8 and 0.8 per cent respectively. 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 (Table 2 and Maps 2, 3).

When analysing the results by district, Gozo and Comino district had an average of 114 domestic installations per 1,000 population, followed by the Western and South Eastern districts at 85 and 69 installations respectively. The lowest ratio was registered in the Northern Harbour district, with 36 installations per 1,000 population.

Production of energy from PVs: 2023

Total kWp amounted to 241,125.9, an increase of 8.3 per cent over 2022. The commercial sector accounted for 52.7 per cent of total kWp, followed by 44.7 and 2.6 per cent in the domestic and public sectors respectively. The peak power rating of an average PV system in the domestic sector stood at 3.4 kWp, whereas that for the commercial and public sectors amounted to 64.6 and 21.5 kWp respectively.

When compared to the situation in 2022, generation of energy from grid-connected PVs increased by 6.7 per cent, totalling an estimated value of 309.3 GWh. Most energy was generated in the South Eastern and Northern Harbour districts at 22.9 and 17.4 per cent of the total GWh respectively. Increases were highest in the Northern Harbour district (9.3 per cent) and lowest in the Gozo and Comino district (2.2 per cent).
