Weekly or daily cleaning

Use a clean cloth and water only (no soap or detergent), and clean at early hours when panels are still not hot. Also clean any small modules that are installed

Prevention of shading

Remove shrubs around the solar panels

Ensure that nothing in the vicinity can hide panels

Do not allow the construction of structures that might overshadow the panels

Inspection of the constituents

Check the cleanliness, blocking of cables and connections of all visible equipment (pump, panels, inverter...)

Once a week, check the cables whenever possible and seek possible damage (cuts, worn or eaten by rodent’s insulation ...). Ensure there are mo exposed cables.

Daily control of the state equipment and layout

Ensure there is no dew condensation, no peculiar smell, stable vibration, normal temperature of the body, no abnormal noise etc.

Ensure connections are firm (tighten loose terminals, nuts, cable glands etc). In case of a problem, consult an expert. Do not tamper with it.

Frequently monitor the flow output from the pump and the current consumed by the pump.

Avoid short circuiting your cables as this can lead to system damage.

Safety: DO NOT

Throw objects at the solar module.

Stand or step on the module.

Try to repair your solar module if it breaks because once the module is broken, it cannot be repaired.

Carry out modifications on your system without technical guidance from your system supplier or a qualified technician.

If a solar battery is installed, DO:

Keep the solar battery in a clean environment.

Place the solar battery on a stable surface to prevent it from falling or tilting.

Keep the solar battery safely inside a well-ventilated wooden box.

Always check the level of electrolyte in every cell of your battery. If the level has gone down, add some distilled (or de-ionized) water (for open batteries).

Top the solar battery with distilled water from a good source, never use tap or rain water since they have impurities, which may damage your battery.

Apply Vaseline, not grease or oil, on both battery terminals to prevent acid mist (a white substance) forming on them.

Clean the terminals and battery's top surface regularly with hot water to prevent accumulation of acid mist which causes batteries to self discharge.

If a solar battery is installed, DO NOT:

Short -circuit the terminals of your solar battery. Your solar battery stores huge amounts of energy.

Pour out the acid and fill with fresh acid as it damages the battery.

Add acid to your solar battery at any time.

Accept advice on battery repairs from unauthorized persons. Rather, contact battery suppliers directly.

Keep the solar battery near open flames as there is danger of explosion.

Take your old batteries for repair.
