3. Maintenance

The Elon® 100 has been designed to last for a very long time and has no moving parts aside from three

electrical relays. No maintenance is required on the Elon® 100.

3.1 Solar PV module maintenance

It is recommended that a qualified electrician inspect your solar PV installation at least once a year.

1. At least once a week, check whether the indicator lights are flashing rapidly. (This indicates an

isolation fault – call your electrician.)

2. Perform regular visual checks (at least once a year). Check for soiling or any visible damage to

any of the modules.

3. If the modules have been soiled by dirt, dust, debris, bird droppings or any other materials,

use water only and a sponge or soft cloth to clean them. Do the cleaning early in the morning

or late in the afternoon, as the modules are hot during the day. Avoid using a water jet that

may leave streaks on the modules.

4. Visually inspect cables for any degradation or loose fittings.

5. Look for any shading problems, such as trees that may have grown.

6. An electrician can check solar power production on a sunny day to ensure that the system is

still producing power at expected levels. A thermal imaging camera can be used to inspect

modules for hot spots.

7. Follow any specific maintenance instructions from the solar PV module manufacturer.
