Complex, multi-phase, detail & data heavy projects are our forte. 2DegreesKelvin pride ourselves on our ability to receive enquiries from our customers and extensively & meticulously develop optimised workflows and technology solutions to deliver said project to the highest levels possible. If you are looking for man-in-a-van cowboys to get a job done as cheaply and quickly as possible, then we are not your partner. If you are looking for professional & considered project delivery, high quality, health & safety and communication levels and service excellence, then we are your partner.
Check out some of the projects we have delivered:
Each site was thoroughly assessed in terms of its current operational performance, including a full design review. Centralised inverters to be changed out for a centralised-string configuration. Site string configuration re-configured to reduce row shading losses. Near horizon-line assessment conducted with module level PV-Syst simulations. Proposed targeted MPPT tracing string optimisers on shade effected areas.
Yield improvements: >5.5%
Payback: <3 years
A High-Definition drone survey was conducted to identify module delamination (4 x site / 220,000 modules). Site team mobilised to conduct defect marking, module disconnection, demounting, transportation, cleaning, scanning (for warranty claim compliance), packing & shipment to OEM. Purpose-built array access platforms designed and used. Over 11,500 modules exchanged through winter program. Project delivered on time in a professional & safe manner.
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 2,500 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 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.
Over 1MWp of PV modules had EL images taken using our 4 x landscape multi-EL camera tripod rig, and string powering technology. Each module was judged against an industry-leading judgement criteria and classified. Comprehensive engineering report provided which concluded that suspicion was unfounded. However, extensive damage found which can be exchanged with spares to realise instant performance gains.
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.
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.
