Photovoltaic systems

Photo voltaic system on the roof of building Magasin 6 in Frihamnen port

As part of the company's efforts to become a fossil fuel-free operation, Ports of Stockholm has chosen to commit to photovoltaic systems. There are currently five photovoltaic systems - at Frihamnen port, Värtahamnen port, Port of Nynäshamn and Port of Kapellskär.

Ports of Stockholm's photovoltaic systems can produce electricity at a cost that is comparable to the purchase price of the electricity market. The systems have a guaranteed effect of at least 25 years and experiences so far are positive.

The photovoltaic system at Magasin 6, Frihamnen port

  • The system consists of 885 solar panels.
  • The total photovoltaic system surface area is around 1 400 m².
  • The maximum power output is around 225 kW.
  • The estimated annual electricity production is around 200 000 kWh.
  • The total cost of the facility was approximately SEK 3 million. However, Ports of Stockholm was granted 35 percent (about SEK 1 million) in state subsidies.
  • The cost per installed kW was approximately SEK 8 900/kW (including subsidies).

The photovoltaic system at the Port of Nynäshamn

  • The system consists of just over 500 solar panels.
  • The total photovoltaic system area is around 800 m².
  • The maximum power output is around 125 kW.
  • The estimated annual electricity production is around 125 000 kWh.
  • The total cost of the facility was around SEK 1.4 million. However, Ports of Stockholm was granted 35 percent (about SEK 480,000) in state subsidies.
  • The cost per installed kW was approximately SEK 7 400/kW (including subsidies).

The photovoltaic system at the Port of Kapellskär

  • The system consists of 255 solar panels.
  • The total photovoltaic system area is around 400 m².
  • The maximum power output is around 60 kW.
  • The estimated annual electricity production is around 55 000 kWh.
  • The total cost of the facility was approximately SEK 1.17 million.
  • The cost per installed kW was approximately SEK 19 400/kW.

The photovoltaic system at Värtahamnen port

  • The system consists of 166 solar panels.
  • The total photovoltaic system area is around 270 m².
  • The maximum power output is around 55 kW.
  • The estimated annual electricity production is around 55 000 kWh.
  • The photovoltaic system was included in the of building of the new passenger terminal and therefore no separate cost for the facility is reported.

The photovoltaic system at Banankompaniet, Frihamnen port

  • The system consists of 275 solar panels.
  • The total photovoltaic system surface area is around 440 m².
  • The maximum power output is around 83 kW.
  • The estimated annual electricity production is around 75 600 kWh.
  • The total cost of the facility was approximately SEK 1.1 million. Ports of Stockholm has applied for state subsidies.
  • The cost per installed kW was approximately SEK 13 100/kW (without subsidies).
