3. Maintenance
This section describes how to maintain solar modules and wind turbines. Under normal operating conditions
the pumps and the controls are maintenance-free.
3.1 Solar modules
Routine maintenance
Cleaning
• The solar modules must be cleaned when they
are dirty. Use only clean water without soap and
a soft brush or cloth. Make sure there is no sand
or other abrasive particles in the water.
• There is no need to clean the modules under-
neath.
Clearing
• Make sure that the sun can shine directly on the
modules.
• Cut down grass or trees that cast a shadow on
the solar modules.
Tighten
• Tighten screws and nuts on the support structure
if they have loosened.
