Solar street lamps run in the open air for a long time, and suffer from various severe meteorological environments

such as rainstorm, blizzard, strong typhoon and dust all the year round. As a core power generation component,

photovoltaic panels are easily affected with moisture and damaged, which leads to circuit faults such as short circuit

and decreased insulation performance, which directly shortens the service life of energy storage batteries and

reduces the power generation efficiency and night lighting stability of the whole street lamp system. Therefore, the

operation and maintenance personnel need to carry out special inspection and protective maintenance of solar

photovoltaic modules before and after bad weather. Combined with industry operation and maintenance standards,

the standardized maintenance items of photovoltaic panels for solar street lamps are as follows:

1. Patrol inspection of the support structure: comprehensively inspect the photovoltaic panel mounting support, 

and investigate the security risks such as corrosion, cracking, deformation and bolt looseness of the support, so as

to ensure that the photovoltaic module is firmly installed and resist extreme weather impacts such as strong wind

and heavy rainfall.

2. Cleaning of panel obstructions: regularly clean the surface and surrounding obstructions of photovoltaic panels,

including fallen leaves, dead branches, dust, bird droppings, snow, billboard obstructions, etc., to avoid the reduction

of photoelectric conversion efficiency caused by panel obstruction and ensure the normal power generation of

photovoltaic modules.

3. Appearance inspection of components: carefully check whether there are any damage problems such as cracking,

scratches, bulging, aging and breakage on the toughened glass surface layer and back plate of photovoltaic panels,

so as to find faults early and replace them early to avoid leakage of components and power generation failure.

4. Detection of line connection reliability: check the connection status of photovoltaic panel output connection

line and grounding line, and check whether the terminal is loose, falling off and oxidized into water, so as to ensure

good line contact and effective grounding protection, and eliminate potential safety hazards of line disconnection

and leakage.

5. Cleaning of colloidal stains on the panel: For the stubborn gum, shellac, oil stain and other attachments that

are difficult to be washed naturally on the surface of photovoltaic panels, professional cleaning tools are adopted

to restore the light transmittance of the panel and ensure that the photoelectric conversion efficiency is maintained

in the standard range.
