There are two types of solar panel encapsulation methods: epoxy-coated solar panels (epoxy encapsulation) and laminated solar panels (glass/PET/ETFE encapsulation). What's the difference between them?
Production Process
l Epoxy-coated solar panels:
1) Mix two different types of glue in a suitable ratio.
2) Place the prepared glue into the glue dispenser and drip it onto the solar cell surface.
3) After dripping, vacuum the surface.
4) After vacuuming, bake the surface to cure the epoxy resin.
5) Remove any excess glue.
l Laminated solar panels:
1) Prepare the surface encapsulation with glass, PET, or ETFE.
2) Laminate the glass/PET/ETFE/EVA/PVA/PVA/PVC/PVC/EVA/PVC ...
3) After lamination, place the panels in a laminator (temperature and time must be within specified ranges to prevent delamination).
4) After lamination, remove any excess glue.
Power
l Epoxy-coated solar panels typically have a power of 0.1W-6W and are used in applications requiring a small size, such as solar lawn lights, solar wall lights, solar crafts, solar toys, solar radios, solar flashlights, solar mobile phone chargers, and small solar water pumps.
l Laminated solar panels can have a power of 30mW-500W or more and are used in applications such as solar sights, solar cameras, solar RVs, and solar handheld lanterns. These panels can be customized to meet customer requirements.
Service Life
Epoxy-coated solar panels have a service life of 2-3 years. The transparent surface of the epoxy will gradually turn yellow over time, further reducing the panel's service life. The life of laminated solar panels is determined by their surface material. The service life of PET solar panels is 3-5 years, the service life of ETFE solar panels is about 5-10 years, and the service life of glass solar panels is about 25 years. The life of laminated panels is much longer than that of epoxy solar panels.
