Best practices are applied in conjunction with manufacturer-prescribed procedures, to ensure that the equipment used on the solar plants is kept in the finest condition. Proper maintenance and skilled handling of solar equipment inevitably reduces the occurrence of failures and production loss.
Corrective maintenance is carried out upon the detection of faults or failures either by remote monitoring and supervision or during regular inspections and specific measurement activities on each site. Corrective Maintenance is carried out by qualified teams in order to restore the PV plant systems, equipment or components to a status where they can perform their required function.
Corrective Maintenance includes fault diagnosis / troubleshooting, temporary and permanent repairs.
We make use of a specialised module cleaning devices to remove soiling from the solar panels that may interfere with the optimal conversion of solar energy. Module cleaning is done manually or with machines consisting 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.
We make use of specialised grass cutting devices to maintain a maximum grass length to prevent the shading of the solar panels which may interfere with the optimal conversion of solar energy. Grass cutting is done manually with brush cutters or with machines consisting of a low positioned mechanical arm and slasher that attaches 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 predetermined height.
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. The Scada rooms are equipped with monitoring software of the highest standards that allows the operators to closely observe a full range of parameters to ensure that the respective plants are operating smoothly and at maximum capacity. The Scada system is equipped with a cautionary notification system that alarms operators of any problems detected on-site at any of the plants that may interfere with the harvesting or conversion of solar energy.
Some of the key functions of the Scada Operators include:
- • Supervising the maintenance of the plants
- • Managing the warehouses and equipment
- • Generating statistical reports
- • Monitoring
- • Supervision
- • Warehouse management
- • Corrective maintenance
- • Preventive maintenance
- • Production prediction
