Our Solution

Bouygues Energies & Services built and connected the new facility for Wirsol. The 30-acre site houses approximately 20,000 PV panels and two medium voltage power stations, which successfully produce electricity for the local area. Inverters and transformers housed in the power stations convert the DC output into AC to supply to the mains. The project was delivered on schedule, approved and energised in March 2016.

We also upgraded the access road from the public highway to the site (c250-300m), using a lime stabilisation process. This allowed access to the site for construction and maintenance purposes.

Bouygues Energies & Services National Operations Centre remotely monitors the CCTV on the site 24/7. Our monitoring works down to each string level, checking for output and any faults.
