Maintenance
◇
To ensure the best performance of the solar panels,
United Renewable Energy
provide the following maintenance measures:
◇
The solar panel should be cleaned in the morning or evening when the power is low
or no power is processing.
◇
Clean the glass surface when necessary through clean water and soft objects. The
neutral detergent should be used for cleaning while the acidic or alkaline or
abrasive detergent is forbidden.
For large-scale systems, when considering whether all of the dust and deposits on the
solar cell array should be cleaned or not, factors such as cleaning costs, increased
energy output after cleaning, and the time it takes to get dirty again after cleaning
need to be taken into consideration. If you are not sure whether the array or its
sections need to be cleaned or not, you should firstly select the heavily polluted array
string and then measure and record the inverter's input current from that string.
1)
Clean all the modules within a string.
2)
Measure the input current of the inverter again and calculate improvement
percentage after the cleaning.
3) If the improvement degree is less than 5%, it is usually not worthy to pay the cost
for cleaning.
◇
In case of rainy weather, do not deliver the electricity if the inverter or other
electrical equipment is power off. It is better to check and ensure that there is no
problem in the lines before sending the electricity.
◇
When cleaning, the solar panel cannot be washed with a high-pressure water gun
for avoiding line leakage caused by excessive pressure in the connection place of
the solar panel.
◇
Conduct a mechanical and electrical inspection for every six months and ensure
that the surface is clean and the connection is reliable.
◇
If any other abnormal situation occurs, please consult factory or experienced
engineer.
◇
Observe the maintenance instructions for all parts used in the system, such as
bracket, charge controller, inverter, solar cell, etc.
