How long is the service life of solar edge sealing tape?

The service life of solar edge sealing tape is not fixed and will be affected by many factors, usually 10-25 years. The following is a detailed introduction for you:

Tape material

Acrylate tape: It has good weather resistance and ultraviolet resistance, and its service life can usually reach 10-15 years.

Silicone tape: Excellent in high temperature resistance, low temperature resistance and weatherability. The service life of this kind of adhesive tape is relatively long, generally 15-25 years.

operational environment

Temperature influence: In high temperature environment, the tape is prone to softening, deformation and viscosity reduction, thus accelerating the aging of the tape and shortening its service life. For example, in high temperature areas such as desert, the service life of solar edge sealing tape may be reduced by 2-5 years. However, in the low temperature environment, the adhesive tape will become hard and brittle, which will lead to the decrease of its flexibility and adhesion, easy to crack and fall off, and will also affect the service life of the adhesive tape.

Humidity influence: high humidity environment will affect the adhesive force between the tape and the frame, resulting in the decline of sealing performance. At the same time, the humidity will accelerate the corrosion of the metal frame, which will affect the adhesion effect of the tape and shorten the service life of the tape. For example, in coastal areas or tropical rain forest areas, high humidity environment may reduce the service life of adhesive tape by 3-6 years.

Influence of ultraviolet rays: Ultraviolet rays have high energy. Long-term irradiation will degrade and age the polymer materials of the adhesive tape, resulting in yellow and brittle color of the adhesive tape, reduced viscosity and poor sealing performance, thus greatly shortening the service life of the adhesive tape. In high altitude areas or areas with strong sunlight, the damage of ultraviolet rays to the tape is more obvious, which may shorten the service life of the tape by 5-10 years.

Installation quality

Improper surface treatment: Before installing the adhesive tape, if the surface of the frame of the solar panel is not thoroughly cleaned and treated, there will be impurities such as dust, dirt, grease or moisture, which will hinder the full contact and adhesion between the adhesive tape and the frame surface, resulting in the decrease of adhesive force, which is prone to problems such as edge warping, blistering and falling off, thus seriously affecting the service life of the adhesive tape and possibly shortening it by 3-8 years.

Non-standard pasting operation: in the process of pasting the adhesive tape, if the correct methods and steps are not followed, for example, the adhesive tape is not aligned with the edge of the frame and is skewed; When pasting, the air between the adhesive tape and the frame is not fully exhausted, forming bubbles; The adhesive tape is not pressed evenly with proper tools, which leads to the weak bonding between the adhesive tape and the frame. These irregular operations will affect the sealing performance and bonding effect of the adhesive tape, reduce the service life of the adhesive tape, and may reduce it by 2-6 years.
