Aerial thermographic inspection for solar PV plants in Malaysia
PVSCAN Engineering finds the modules, strings and connections that are quietly costing your plant yield. Independent infrared inspection by unmanned aircraft, with every module identified and every anomaly ranked so your O&M team fixes what matters first.
Plant stays online during the survey. Enquiries answered within one working day.
Who we work for
Owners and operators who need an independent picture of plant health, not a sales pitch for repairs.
Asset owners & IPPs
Large-scale solar (LSS) and utility plants under PPA. Know your real module-level losses before they show up as a missed generation target.
O&M contractors
Turn a vague "plant is underperforming" into a prioritised, module-by-module work order your field team can act on.
EPCs & developers
Independent evidence at commissioning, end of defects liability period and handover, so disputes are settled with data.
Investors, lenders & insurers
Technical due diligence before acquisition or refinancing, and documented evidence for warranty and insurance claims.
What you receive
- Full-plant thermal survey of every module, string and combiner within scope, flown while the plant generates.
- Every module identified and mapped to your plant layout, so a finding points to one physical panel, not a rough area.
- Anomalies classified in line with IEC TS 62446-3 practice: hotspots, bypass-diode faults, open strings, disconnected modules, soiling and shading patterns, and more.
- Estimated yield loss per finding, so repairs are ranked by ringgit recovered rather than by count.
- Repair list and site map your technicians can take to the field.
- Secure client portal to browse results, filter by severity and track resolved items across repeat inspections.
The scope, plant types and deliverables are tailored to each site. See our services or contact us to discuss yours.
Why plant owners inspect from the air
A solar plant rarely fails all at once. It loses a few percent here and there: a bypass diode that has failed closed, a string that tripped and nobody noticed, a connector heating up under load, a cluster of modules degrading faster than the rest. Inverter data tells you that production is down. It does not tell you which of ten thousand modules is responsible.
Aerial infrared thermography sees the whole plant under real operating load in a fraction of the time a ground crew needs, and it sees faults that are invisible to the eye. Combined with per-module identification, it turns a performance ratio problem into a short, ranked list of physical repairs.
Typical triggers for an inspection
- Performance ratio drifting below the PPA or financial model
- Commissioning or provisional acceptance of a new plant
- End of the defects liability or module warranty period
- Annual or bi-annual O&M health check
- After storms, flooding, lightning or grid events
- Acquisition, refinancing or insurance renewal
How an engagement works
- Talk to us
Share the plant location, type and capacity by WhatsApp or email. We come back with questions, a scope and a quotation.
- Plan
We agree access, dates and safety arrangements with your site team and handle the required aviation permissions.
- Survey
The plant is flown under operating conditions. No shutdown, no interruption to generation.
- Analyse
Every module is identified and each anomaly is classified, severity-rated and given an estimated yield loss.
- Deliver & support
Results go to your client portal with a report and repair list. We walk your team through the findings.
Plant types we inspect
Ground-mounted solar farms
LSS and utility-scale plants from a few MW to hundreds of MW. Fixed-tilt and tracker arrays.
Solar farm inspection →Rooftop & C&I systems
Factory, warehouse, mall and campus rooftops under NEM, SELCO or corporate PPA arrangements.
Rooftop inspection →Floating solar
Reservoir, lake and ex-mining-pond installations where access by boat makes ground inspection slow and costly.
Floating solar inspection →Due diligence & handover
Independent condition assessment for acquisitions, commissioning, warranty expiry and insurance claims.
Due diligence →Discuss your plant with us
Every plant is different. Send us the basics and we will propose a scope that fits your site, your budget and your reporting needs.
Other aerial survey services
Solar PV inspection is our core work. The same field capability also serves telecommunications, construction and land clients.
Telco tower surveys
Panoramas at proposed antenna heights and line-of-sight checks between towers, including links where neither tower exists yet.
Panorama & LOS check →Construction & highway progress
Scheduled aerial progress reports for building sites, highways and infrastructure projects.
Progress reporting →Land & quarry mapping
Orthomosaics, terrain models and stockpile or earthworks volumes for land, quarries and plantations.
