Services

Operation and maintenance services offered by O&M:

Monitoring

By monitoring all production-influencing parameters, such as the state of inverters, production levels and weather conditions, the plants are kept functioning at their optimum capacities.

Preventive maintenance

Best practices are applied, in conjunction with manufacturer-prescribed procedures, to ensure that the equipment used on solar plants is kept in the finest condition. Proper maintenance and skilled handling of solar equipment inevitably reduces the occurrence of errors and production loss.

Corrective maintenance

As faults are detected, urgent care is given to repair, restore or replace the defective devices. The skilled application of corrective maintenance not only solves the immediate problem, but avoids a range of costly system failures.

 

RCC

The Remote Control Center is located at the O&M Solar head office in Bloemfontein. The center is equipped with monitoring software of the highest standards that allows the operators to closely observe a full range of parameters to ensure that both the Lesedi and the Letsatsi plants are operating at smoothly and at maximum capacity. The center is equipped with a cautionary notification system that alarms operators of any problems detected on-site at the Lesedi and Letsatsi plants that may interfere with the harvesting or conversion of solar energy.

Some of the key functions of the RCC are:

  • The management of all O&M Solar systems
  • Supervising the maintenance of the Lesedi and Letsatsi plants
  • Managing the warehouses and equipment
  • Generating statistical reports

The RCC in Bloemfontein offers the following services (this section is to be moved to the top of the page, with the rest of the RCC content):

  • Monitoring
  • Supervision
  • Warehouse management
  • Corrective maintenance
  • Preventive maintenance
  • Production prediction

 

Preventive maintenance

By implementing manufacturer-prescribed procedures, our trained workers maintain the equipment on the solar plants to ensure that all the components of the system function perfectly and thereby eliminating preventable problems.

 

Corrective maintenance

An immediate response to faulty equipment and detected irregularities keep the solar plants operational and in good condition. Corrective maintenance by means of repairs, restorations and replacements keeps systematic equipment failure and energy production loss at bay.

Module cleaning

O&M Solar makes use of a specialised module cleaning device to remove impurities from the solar panels that may interfere with the optimal conversion of sun energy. The module cleaning machine consists of an outstretched mechanical arm that attaches to a tractor. The modules are cleaned with soft, non-scratching bristles and water from the on-site water purification plants.

The video below shows the module cleaning machine in action. Using this system, we can clean up to 2/4 mw per day.

 

Grass cutting & controlled vegetation

After in-depth research, O&M Solar has designed and built a specialised device for maintaining the natural occurring vegetation at solar plants. The device consists of a low-positioned mechanical arm that’s attached to a tractor. As the tractor navigates through the modules, the cutting device extends below the modules where it mimics a traditional lawn mower by levelling the vegetation to a manageable height.

The video below demonstrates the procedure.
