10 year original Maintenance Plan (Optional)
Until recently, PV module trouble was rather difficult to detect than Inverters.
However, we now have “I-V curve tester” (below), which can make diagnosis of PV module.
10 items to be tested in Maintenance program
Mechanical check points
- 1.PV module
- 2.Junction Box
- 3.Power Conditioner
- 4.Voltage amplifier
- 5.Connecting pipes
Operational check points
- 6.Power Conditioner operation
- 7.DC voltage adjuster operation
Numerical Check points
- 8.Open circuit voltage, I-V curve etc.
- 9.Power Conditioner performance
Data Check points
- 10. Generating Power Now/History
● 10 Year Plan (once a year; 10 times) - > 125,000 JPY + Tax
● Additional maintenance -> 15,000 JPY + Tax
