Maintenance, Diagnosis and Evaluation
The Optimal Solutions to Improve Your System Efficiency
Why is maintenance necessary?
There are various causes of malfunctions in solar power generation systems, such as natural disasters, deterioration over time, breakdowns and mischief. Module cracks can be visually checked. Any system accidents, ground faults, short circuits, etc., can be verified with alarms from the monitor.
However, malfunctions in nonvisible areas such as inside the module are not easily noticed even if the generated power amount is low, and as a result of the progress of the symptoms, other devices are adversely affected and the amount of power sold decreases.
Periodic inspection enables early detection and reliable maintenance for your successful power generation business.
Panel damage due to typhoons, lightning strikes, and snow cover
Dirty panel due to bird droppings
Panel removal or damage due to improper attachment or loose connection
Short-circuiting and burning due to small animals
Cable damage / burnout
Panel Internal Defect
Through periodic maintenance, the amount of these problems can be reduced.
I-V Characteristic Measurement
String Resistance Measurement
Insulation Resistance Measurement
Visual Inspection of Solar Panels
PCS Internal Visual Inspection and Error Checking
Visual Inspections of Other Components
Visual Inspection of High Voltage Equipment
Record Instrument Readings
Inspect with a Thermal Camera
EL Luminescence Test
Module Check using a Drone
A visual inspection from above using a drone equipped with a thermal camera enables a wide area to be confirmed in a short time, and a module suspected of being defective can be detected quickly.
※ Inspection by drone is performed only when necessary.
Perform a technical evaluation of the quality level and value, by diagnosing the soundness of the overall configuration of the equipment for power generation systems and facilities.
Based on the results, we will propose concrete measures to implement “Revamping and/or Repowering” of Solar Power Systems.
Solar Panel Check
Without removing the installed solar panels, the same test as performed at the pre-shipment inspection will be performed at site using special maintenance test equipment.
Inspection of the Entire Power Plant
Inspect and measure the facilities of the entire power plant.
Overall Evaluation of the Entire System
Based on the above inspection results, we will comprehensively evaluate the power generation system in 8 areas that are not generally checked.
|Feasibility (System Evaluation)
|Electricity Sale Continuity

|Environmental resistance / Dust Resistance （Facility Durability）
|Conformity to the Landscape, Design, Appearance, P.R
Consultation About O & M
Power generated amount is lower than last year
How much does the maintenance service cost?
Having trouble of making preparation toward output control.
It’s difficult to inspect the plant because it’s located far away
I don’t understand why the inverter stops working sometimes
