Building our portfolio of onsite solar PV installations
30 Dec 2025
A new solar photovoltaic (‘PV’) installation at our Intertek Minerals laboratory in Tarkwa, Ghana, means that we are producing and consuming our own electricity in 13 countries as of the end of 2025.
Comprising 570 panels, the grid-connected PV system – installed across the roofs of a sample preparation laboratory and two car ports – allows the generated electricity to feed directly into the Tarkwa laboratory’s internal power network. It is designed to generate clean, renewable electricity for the laboratory’s operational needs, directly reducing dependence on grid-supplied energy and cutting carbon emissions. With a total capacity of over 250 kilowatt-peak, the panels are expected to produce a monthly generation output of approximately 26,616 kilowatt-hours – enough power to supply more than 100 average Ghanaian households for one year.
The Tarkwa laboratory was chosen for this project due to the energy-intensive nature of its operations. As well as supporting a significant reduction in site-level emissions, the PV system demonstrates Intertek’s commitment to sustainability and leadership when it comes to laboratory operations.
In addition to Ghana, we also have site-specific solar PV installations in Australia, Bangladesh, Denmark, France, India, Kenya, Mexico, Poland, South Korea, Thailand, the UK and the USA.
