One of the largest solar parking canopy projects in the UK

06 September 2023

Portsmouth approves a major scheme

This scheme at the Lakeside North Harbour site will put roof-mounted solar PV arrays across five buildings, solar car park canopies in 3 car parks with battery storage installed alongside. 

Solar Park canopies have the added advantage of sheltering cars and reducing the need to use airconditioning in summer, and also avoides overheating of EV Vehicle batteries.   

The works will consist of:  

  • 1,820 roof-mounted solar PV panels across 5 buildings  
  • 7,105 solar PV panels installed above existing car parking spaces, creating solar canopies.  
  • Electric vehicle (EV) charging points with infrastructure to install additional charging points as demand increases   
  • 2MW battery installation to store excess solar energy, to be used at peak periods during the day and provide services to the local electricity network at times of high demand 

More than 4million KwH

The Solar PV system will generate more than 4 million kWh’s per annum which is the same as powering 1,300 homes (average 3-bed house) for a year and is projected to save more than 860 tonnes of carbon dioxide from being emitted each year.   

The Solar PV and battery installation started on 21 August 2023 and will be completed by Autumn 2024.   

The business park will consume just over 64% of the generated power which equates to 37% of the site’s electricity requirements, the same as over 1,000 homes’ annual electricity consumption. 

Grid use optimised by Battery Storage

The battery storage will be controlled to ensure it maximises the benefit to Lakeside North Harbour. In times of high power prices, the battery will discharge to Lakeside to minimise consumption from the grid.  During grid peaks and troughs the battery will discharge/charge, take part in other grid services with any unused power exported to the grid.  


There is a major scheme being promoted by the university see link below.  The Planning application 22/P/02178 that will larger by a factor of 4 to 5 times than the Portsmouth scheme but is based solely on panels located on Agricultural Land.
