Connecting to the electrical network
The connection of one or more modules to the electrical network is not described in this
manual, as it must be performed by a qualified technician because small electrical systems are
subject to specific regulatory constraints and safety regulations.
MAINTENANCE
Photovoltaic modules require very little maintenance because of the absence of moving parts.
Maintenance includes the following:
•
regular cleaning of the module;
•
periodic inspection;
•
electrical performance checks.
Cleaning the module
Dirt accumulated on the upper surface reduces performance and can cause adverse effects
similar to those caused by shade. The problem is more pronounced in areas with high smog
levels or the presence of birds or trees.
The intensity of the effect depends on the opacity of the accumulations (grime, soot, leaves,
bird droppings, etc.). In many cases, rain may reduce or eliminate the accumulation of
impurities on the modules.
Cleaning involves simply washing the module with fresh water or isopropyl alcohol using non-
abrasive sponges. Do not use pressurized water jets.
Inspection
It is a good rule to inspect the photovoltaic system periodically in order to check the condition of
the solar panels and the connections between the devices.
Electrical performance checks
Periodic electrical performance checks help to ensure the proper functioning of the
photovoltaic module: for example, a reduction of the electrical power generated may
indicate an isolated shady area on one or more cells, which can then be rectified to obtain
optimal performance.
