SPIS Toolbox - Implement Maintenance Routines

Implement Maintenance Routines

Once the maintenance plan is in place and the responsible persons identified, the maintenance should become a routine.

Critical regular maintenance activities are:

1. Check daily if the system is working. If the pump is not working:

1. check the water source and pipes (any dirt, blockage, enoughwater?);
2. check theelectronics (any burned parts, loose wires, emergency lights?).

2. Inspect the system once a week with respect to:

1. energy generated by PVsystem;
2. pump performance (pumpingrate);
3. condition of water source (purity of water);
4. condition of controller and electronics (visible signs ofmalfunctioning);
5. blockage of drip emitters;
6. condition of water storage facility and pipes (leaks, waterlevel);
7. condition of solar panels and their mounting system (stability, cleanness).

3. Clean solar panels every two to four weeks:

1. clean water and a little scrubbing with a cloth covered sponge or soft brush should remove the most persistent grime;
2. clean in the early morning or late evening, when panels are cool;
3. do not step or walk on the panels as they could be damaged.

 

Note: Hot panels should not be sprayed with cold water – they might crack!

Visual check of the solar panels

4. Throughout the year (every two to three months)the PV system should be checked thoroughly so that:

1. no plants grow close to the panel, the mounting structure, water source, controller, junction box, etc.;
2. there is no shade on the panels (plants, poles, fences etc.), so as to permit maximum radiation;
3. the fencing of the solar array is not damaged;
4. the mounting structures are stable.

In addition, the reservoir should be cleaned and the irrigation system should be flushed regularly.

Note: Inspect your system always after strong winds, hail storms, lightening or earth quakes have occurred in your region.

After the first experience with a particular maintenance plan, the timing and frequency of maintenance can be adapted to suit the local conditions and capacities of the producer.

Note: Call your technology provider (panels, pumping, and controller) or electrician (electronics) who installed the system for help – this should be part of the service contract.

Outcome / Product                         

• Maintenance plan;
• maintenance sheets;
• checklist for visits to farm;
• weekly inspection sheet;
• bi-monthly inspection sheet;
• MAINTAIN 01-Maintenance Checklist.

People / Stakeholders    

• Producers /producer groups;
• agricultural advisors;
• technology and service providers (electricians, companies providing solar powered systems).

Important issues& Decisions

• Maintaining an SPIS does not require advanced technical skills and the overall effort is relatively low, when compared to other technologies.
• It is important to establish inspection and maintenance routines and to schedule them as part of the work plan of the farm.
