Product Description

The Photovoltaic Sealing Strip is an essential element engineered to perfection for the seamless installation and efficient sealing of solar photovoltaic panels. It plays a pivotal role in maintaining the integrity of panel connections by offering superb waterproofing, dustproofing, and remarkable resistance to weather and aging, thereby guaranteeing the photovoltaic system operates smoothly and reliably over extended periods. Below is an in-depth exploration of the features and advantages of photovoltaic sealing strips:

1, Material and Characteristics

1. Main material: The high-performance Photovoltaic Sealing Strips are predominantly crafted from premium quality ethylene propylene diene monomer (EPDM) or superior silicone.

Ethylene propylene diene monomer (EPDM): EPDM is renowned for its outstanding heat resistance, unbeatable weather durability, and exceptional ozone tolerance. It boasts robust tensile strength, impressive elasticity, and a wide temperature resistance range (-40 ºC~120 ºC). Moreover, it exhibits remarkable aging resistance along with excellent physical and mechanical prowess.

Silicone: Known for its superior thermal resilience, silicone offers impeccable high temperature endurance (150-200 ºC) and reliable low temperature stability (-40-60 ºC). Its formidable aging resistance and superior chemical corrosion resistance make it a top choice, along with its excellent electrical insulation attributes.

2. Characteristics:

Waterproof and dustproof: Effectively prevents rainwater and dust from infiltrating the photovoltaic panel, thus safeguarding it from potential harm.

Weather resistant and aging resistant: Capably withstands the harsh effects of natural elements like ultraviolet rays and ozone, maintaining structural integrity without cracking or deforming over time.

High elasticity: Offers excellent rebound capability and resists compression deformation, adapting deftly to the thermal expansion and contraction of photovoltaic panels.

Easy to install: Thoughtfully designed for simplicity, the installation process is straightforward and enhances overall construction efficiency.

2, Type and shape

1. Type: According to material and performance considerations, photovoltaic sealing strips are categorized into EPDM rubber sealing strips and silicone sealing strips.

2. Shape: These sealing strips are available in diverse configurations such as T, D, P, O, etc., tailored to meet varied sealing requirements of different photovoltaic panel connections.

3, Application and Function

1. Application: Widely employed in the installation and sealing of solar photovoltaic panels, these strips are invaluable for photovoltaic module frames, panel gaps, and junction box connections.

2. Function:

Sealed and waterproof: Effectively prevents water ingress into photovoltaic panels, safeguarding circuits and components against moisture and corrosive damage.

• Buffer and shock absorption: Provides a cushioning effect when panels are impacted externally, preserving the integrity and shielding them from potential damage.

• Improve energy efficiency: By significantly reducing dust accumulation on panel surfaces, they enhance photovoltaic conversion efficiency significantly.

4, Selection and installation precautions

1. Selection: When selecting photovoltaic sealing strips, consider the panel’s material, dimensions, and installation environment carefully to choose the ideal material, shape, and size.

2. Installation:

Clean the surface: Prior to installation, ensure that the photovoltaic panel connection surfaces are spotless, dry, and devoid of oil stains and impurities.

• Correct installation: Adhere strictly to the sealing strip's installation guidelines to ensure accurate, complete, and precise placement, avoiding any misalignment or omissions.
