Inspection and Maintenance Service of PV Panels
Generally, life-span of a PV panel is said to be more than 20 years, however, it is very difficult to determine generating performance after installation because of continuously changing power output depending on the irradiance or temperature conditions. PV panels are industrial products: there have been faults and troubles reported due to initial defects, degradation by aging, or other causes. Proper inspection and maintenance are essential to keep the long-term power output after installation.
NPC provides effective inspection and maintenance service for installed PV panels, utilizing our experience and achievement in PV industry so far. “Rakit,” the multi-functional high-speed I-V measurement system, measures up to 4 strings at a time. “EPTiF,” the on-sight EL/PL inspection machine, visualizes the conditions inside PV panels. Using these highly-advanced inspection machines, we provide analysis report full of useful information.
NPC Original Maintenance Service Plans
|1) I-V characteristics measurement
|2) On-site EL image inspection
(where possible defects are found by I-V analysis)
|3) Analysis report
(I-V and EL analysis report)
(I-V analysis report)
(EL analysis report)
NOTE) Plans above are just some examples. We provide customized plan according to your request, budget, etc.
Also, defects inspections using thermography and disconnection detection are available at your request.
Maintenance Service Flow (Plan A)
