Product Description

The photovoltaic sealing strip stands as an indispensable component, purpose-built for the seamless installation and reliable sealing of solar photovoltaic panels. Its primary role is to guarantee that the connections between these panels possess superior waterproofing, dustproofing, weather resistance, and anti-aging qualities. This ensures the photovoltaic system's long-term stability and performance. Below, we delve into a comprehensive description of photovoltaic sealing strips:

1, Material and Characteristics

1. Main material: Photovoltaic sealing strips are primarily crafted from ethylene propylene diene monomer (EPDM) or silicone, renowned for their robust properties.

Ethylene propylene diene monomer (EPDM): Celebrated for its remarkable heat and weather resistance, and exceptional ozone protection. It boasts strong tensile strength, impressive elasticity, and temperature durability (-40 ºC~120 ºC). Its outstanding resistance to aging and superior physical and mechanical properties make it a top choice.

Silicone: Known for its exceptional high temperature endurance (150-200 ºC) and low temperature resilience (-40-60 ºC). It offers excellent aging resistance, outstanding chemical corrosion resistance, and superior electrical insulation.

2. Characteristics:

Waterproof and dustproof: Designed to efficiently prevent rainwater and dust infiltration, safeguarding the photovoltaic panel's interior from harm.

Weather resistant and aging resistant: Built to withstand natural elements like UV rays and ozone, ensuring no cracking or deformation even with prolonged usage.

High elasticity: Provides excellent resilience and resistance to compression deformation, accommodating the expansion and contraction of photovoltaic panels due to temperature variations.

Easy to install: Smartly designed for effortless installation, significantly boosting construction efficiency.

2, Type and shape

1. Type: Photovoltaic sealing strips can be categorized into EPDM rubber sealing strips and silicone sealing strips, based on material and performance.

2. Shape: Available in diverse shapes like T, D, P, O, and more, these strips cater to the diverse sealing requirements of various photovoltaic panel connections.

3, Application and Function

1. Application: Extensively utilized in the installation and sealing of solar photovoltaic panels. They fit photovoltaic module frames, gaps between panels, and connections with junction boxes.

2. Function:

Sealed and waterproof: Effectively bars rainwater from penetrating the photovoltaic panel's interior, thus shielding circuits and components from moisture and corrosion.

• Buffer and shock absorption: Offers a buffering effect when photovoltaic panels experience external impacts, thereby preventing potential damage.

• Improve energy efficiency: Enhanced sealing minimizes dust build-up on photovoltaic panel surfaces, boosting conversion efficiency.

4, Selection and installation precautions

1. Selection: Choose photovoltaic sealing strips by considering the photovoltaic panel's material, dimensions, and installation conditions. Select the optimal material, shape, and size of the sealing strip accordingly.

2. Installation:

Clean the surface: Prior to installation, ensure the photovoltaic panel connection surfaces are immaculate, dry, and free from oil or impurities.

• Correct installation: Adhere strictly to the sealing strip's installation guidelines to ensure precise placement without any oversights or misalignment.
