PV Tester Helps Bring Iconic PV Project To Fruition

Solar Installation PV100 Test Kit at Kings Cross StationOne of the UK’s largest and most complex building-integrated photovoltaic systems has been completed and in the process helped to pioneer the use of unique new PV electrical test instrumentation.

The new 240kWp rooftop PV system installed on London’s iconic King’s Cross railway station has recently been switched on, marking full commissioning of the new £1.3m. project.

In carrying out the PV system design and installation work at Kings Cross, Sundog Energy became the first solar PV contractor to use the new multifunction Seaward Solar Installation PV tester on a major scheme.

The specialist Seaward PV electrical tester is the first dedicated all in one combination tester for solar panel installation. It is capable of carrying out all electrical tests required by BS EN 62446 on grid connected PV systems and eliminates the need for multiple test instruments for PV panel electrical installation and connection.

With the push of a single button the new combination tester carries out the required sequence of electrical tests in a safe and controlled manner, avoiding the risk of contact with exposed live DC conductors.

The PV project on Kings Cross formed part of a larger £550 million redevelopment programme at the station, of which £42 million was allocated to renovating the roof. As part of the renovation, 1,392 custom-made glass laminate solar panels were incorporated into the roof structure.

Specifically, the glass laminate units form part of two large barrel vaulted glass roofing structures which span across the main platforms of the grade 1 listed building, covering an area of more than 2,300 square metres. They will help to generate an estimated 175,000 kWh of solar power per annum which will provide around 10% of the station’s electricity demand.

Martin Cotterell, the founder and chairman of Sundog Energy, said: “King’s Cross has been a fantastic project to work on – but also a labour of love.

“The sheer scale of the installation has presented many major technical and aesthetic design challenges from day one and there has been no margin for error as the work had to be undertaken whist the station remained fully operational.”

Specialist PV electrical test instrumentation forms part of the comprehensive range of Seaward Solar test equipment, accessories and solar PV data recording software for the solar sector.
