Knowledge fuels change - Support energypedia!
For over 10 years, energypedia has been connecting energy experts around the world — helping them share knowledge, learn from each other, and accelerate the global energy transition.
Today, we ask for your support to keep this platform free and accessible to all.
Even a small contribution makes a big difference! If just 10–20% of our 60,000+ monthly visitors donated the equivalent of a cup of coffee — €5 — Energypedia would be fully funded for a whole year.
Is the knowledge you’ve gained through Energypedia this year worth €5 or more?
Your donation keeps the platform running, helps us create new knowledge products, and contributes directly to achieving SDG 7.
Thank you for your support, your donation, big or small, truly matters!
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:
- check the water source and pipes (any dirt, blockage, enoughwater?);
- check theelectronics (any burned parts, loose wires, emergency lights?).
2. Inspect the system once a week with respect to:
- energy generated by PVsystem;
- pump performance (pumpingrate);
- condition of water source (purity of water);
- condition of controller and electronics (visible signs ofmalfunctioning);
- blockage of drip emitters;
- condition of water storage facility and pipes (leaks, waterlevel);
- condition of solar panels and their mounting system (stability, cleanness).
3. Clean solar panels every two to four weeks:
- clean water and a little scrubbing with a cloth covered sponge or soft brush should remove the most persistent grime;
- clean in the early morning or late evening, when panels are cool;
- 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!
