The maintenance of the solar photovoltaic system shall meet the following requirements:

1. All bolts, welds and supports shall be firmly and reliably connected.

2. The anti-corrosion coating on the support surface shall not crack and fall off, otherwise, it shall be timely applied.

The operation and maintenance of solar power station and household solar system shall not only comply with the relevant provisions in 1, but also comply with the following provisions:

1. Solar system building materials and photovoltaic components should be inspected, cleaned, maintained and maintained by professionals regularly. If the following problems are found, they should be adjusted or replaced immediately:

Condensation, water intrusion and failure of insulating glass affect the sight line and thermal performance of photovoltaic curtain wall engineering;

Glass explosion includes thermal cracking of glass and self explosion of tempered glass;

The peeling of coated glass causes the loss of architectural aesthetic feeling;

The glass is loose, cracked and damaged.

2. The drainage system of photovoltaic building materials and photovoltaic components must be kept unblocked and dredged regularly.

3. Doors and windows with solar energy system building materials or photovoltaic components shall be opened and closed flexibly, hardware accessories shall be free from dysfunction or damage, and installation bolts or screws shall not be loose or invalid.

4. The sealant of photovoltaic building materials and photovoltaic components shall be free of degumming, cracking, blistering and other adverse phenomena, and the sealant strip shall not fall off or be damaged.

5. When inspecting, cleaning, maintaining and repairing photovoltaic building materials and components, the machines and equipment (cleaning machine, hanging basket, etc.) used must be firm, flexible and convenient to operate, safe and reliable, and measures should be taken to prevent impact and damage of photovoltaic building materials and components.

6. When cleaning photovoltaic building materials and photovoltaic components indoors, it is forbidden to water into the electrical interface of fireproof partition materials and modules or square array.

7. When replacing the glass of photovoltaic building materials and photovoltaic components of hidden frame glass, the whole module with curing period shall be used.
