Case study 1 - 4 x Site Repower Studies

Scope of work

  • Four 2011 vintage 5MWp (FiT) sites to be assessed for suitability for a repower
  • Inverter reliability problems
  • String configuration
  • Near Horizon Shading Loss

Case study 2 - 11,500 Module Exchange Project

Scope of work

  • Identify all module delamination on 4 x 8MW portfolio (down to 5mm diameter size defects)
  • Exchange defective modules for new replacement modules
  • Comply with the module manufacturers warranty claim process

Outcomes

Case study 3 - Post Shipment & Post Installation Module Quality Assignment

Scope of work

  • Advise on module quality inspection strategy for 50MWp subsidy-free new build
  • Test 2,500 module in the mobile module test machine (post shipment)
  • Test 750 modules with in-situ Electroluminescence (post installation)

Outcomes

Provision of certified, calibrated and lab-grade accuracy mobile test lab to conduct post shipment testing. Mobile lab positioned in onsite tent and module handling team managed. 2DK lab operator gathered 4,500 EL & Flash results marking modules to be followed into the field. Damage found followed designed escalation protocols. 2DK provided EL Pro tripod system to gather 1,750 in-field EL images (post installation) to compare with post shipment images. Installation / handing damage found and replaced. Installation standard introduced for future new build projects.

Case study 4 - High Volume EL

Scope of work

  • Gather 3,600 module Electroluminescence images on defined strings to assess due to suspected clamp over-tightening damage.

Outcomes

Case study 5 - Back Sheet Powdering Investigation

Scope of work

  • Carry out a module Backsheet investigation covering 3 module types on one site.
  • 20% site survey coverage.
  • Report on positive cases of Backsheet deterioration, gathering photographic evidence, module serial numbers and module position data.

Outcomes

2DK delivered a 33% site inspection, over and above client’s expectations. We confirmed that there was categorically no Backsheet deterioration on site covering all three module types. Confirmed that TA’s suspicion was due to one of the module types nameplate stickers were actually deteriorating and had a white residue. Gathered extensive photo & video evidence of findings and presented in a professional & conclusive report.

Case study 6 - Snail Trail Investigation

Scope of work

  • Investigate the snail trails on a 6.5MWp (24,000 module) site and advise on whether they are having a detrimental effect on power output.
  • Advise on whether there is a module warranty claim or not?

Outcomes

A high-resolution video survey was conducted of the site to enable the 2DK team to analyse all 24,000 modules one by one, to quantify the number of effected modules and gather data on the number of effected cells per module. Conclusions could be made on the scale, intensity and locality of the snail trails, which concluded that even though snail trails were extensive, the impact on power at this stage was minimal. Follow up module testing was recommended for the worst effective modules.
