The system was installed in November 2016 and presented challenges due to its city centre location and consequently limited vehicle and material loading access. In addition, there was no onsite storage facility for the material and equipment needed to install the solar PV system.
NWT Energy’s solution to this challenge was to implement a rolling programme to deliver materials to the site. We worked from 8pm through to 6am and delivered material in batches from our warehouse in Sussex. The internal goods lifts was used and we had to pass through tenanted office space to the roof access stairwell to load material to the roof.
During the handover meeting the building management stated they were extremely impressed by the “highest standards of execution of the material loading plan” and noted in particular the care NWT showed to the tenanted office areas we needed to move material through. NWT Energy’s care and attention to detail successfully delivered the project on schedule and the system was within budget. Impact on occupied, tenanted areas within the building was kept to a minimum and care and sensitivity shown to office space users.
We installed the SolarEdge monitoring system, which allows for precise, detailed monitoring of the output of the system and will keep track of the total electricity generation at each array, in real time. If any issues arise during their market-leading 12-year warranty period then the system will alert NWT Energy, who will rectify the issue or exchange the unit for a replacement as part of our ongoing operation and maintenance programme.
