Endangered power plants
-
97%
- 97% of all power plants in Korea are small and medium-sized with capacity of less than 300kW.
- Power plants without professional O&M services
-
49%
- Power plants lacking post-maintenance due to the modules and bankruptcy of contractors
- The test results by Germany’s TUV-Rheinland show that approximately 49% of installed modules have issues in the long-term performance guarantee
Types of hidden module defects
-
Damage inside modules -
Modules with reduced efficiency -
Burnt-out internal terminals -
External issues of unknown cause
Technical due diligence is recommended to the following.
-
Those who are concerned about lower energy output
compared to nearby power plants or expected outcome -
Those who require an overall diagnosis
before/after various warranty periods for defects -
Those who require a system status diagnosis
before operating a new plant or after acquiring an existing plant
