DPD, a leading express parcel delivery company, decided to install a 1 MWp system on the rooftop of their busy parcel distribution hub – and UK headquarters – in Oldbury, West Midlands, as part of their ongoing commitment to being carbon neutral.
Commercial solar PV developer and installer EvoEnergy designed and fitted the system. The site, which is used for sorting and distributing regional parcels for both national and international delivery, offered a good south facing, trapezoidal roof with over 5,000 square metres of space with minimal shading.
The 999.9 kWp system was installed using 3,636 Trina Solar monocrystalline 275 W Honey M Plus modules, connected to 28 SolarEdge inverters.
Due to a local 500 kWp export limitation, EvoEnergy designed the system with a unique High Voltage sensing Export Power Control (XPC) device to constrain the amount of power that would be exported at any given time, allowing DPD to install the full size array they wanted, thus maximising the energy and carbon savings onsite.
Environmental commitment that pays off Now fully operational, the system will generate approximately 860 MWh of clean electricity every year with 85% expected to be used onsite. The system will reduce DPD’s carbon footprint by more than 400 tonnes a year, whilst also providing them with an income from the feed-in tariff for 20 years and significant savings on their energy bills.
The investment forms part of the firm’s “Driving Change” Corporate Social Responsibility strategy which involves every parcel they deliver being ‘carbon neutral’, for all of its customers, at no extra cost to them. The Oldbury site is situated next to a raised section of the busy M5 motorway and the completed array is now a proud spectacle to the thousands of commuters every day to remind them of DPD’s outstanding commitment to the environment.
