CEH Provides O&M Solar Power System services

As we already know, almost PV solar system  just has only one dirty pv panel can affect the capacity of a string which this panel in.
So for the solar system to operate safely and effectively, the investor needs to periodically checks, cleans and maintains it.
CEH can support that works for clients with the highest devotion.
SCOPE OF PERIODIC SYSTEM INSPECTION PROVIDES BY CEH
(Optional)
1.  TEST DC SYSTEM CONNECTING PV PANEL

Testing equipment: HT INSTRUMENTS and HIOKI IR4053

  • Open circuit voltage of string;
  • Short-circuit current of string;
  • Voltage at time of maximum power (Vmp) of string;
  • Measures IV curve to assess anomalies on string;
  • Measures the insulation of string.

2. ELECTRICITY CABINET SYSTEM INSPECTION (AC SYSTEM)

Testing equipment: Fluke 435ii

  • True Rms operating voltage;
  • True Rms operating current;
  • Power factor (Φ cos);
  • THD voltage harmonies;
  • TDD current harmonies;
  • Inverse order component of phase voltage;
  • Intrusion of one-way current;
  • Operating frequency;
  • Pst, Plt voltage flashing.

 3. CHECK EARTHING SYSTEM

Equipment: Kyoritsu Kew 4105A

 4. CHECK PHYSICS OF SYSTEM

4.1 Checking way: by visually, try 5% tightening force

4.2 Test and analyze whole system by thermal drone

Checking equipment:

Drone DJI Matrice 210
Visual Camera DJI Zenmuse XT2
Thermal Camera DJI Zenmuse XT2 640R

5. CLEAN PV PANEL SYSTEM

Checking equipment: Dedicated cleaning machine, Robot…suitable with each system.

During of cleaning process, combine with checking PV panel surface and connection by visually.
