Advantages and Disadvantages of Epoxy Solar Panel

Epoxy Solar Panel is a kind of solar panel, but the encapsulation method is different. The solar cell is cut into small pieces by using a laser cutter to make the required voltage and current, and then encapsulated. Due to the small size, the encapsulation method such as glass laminated or PET laminated solar panel is generally not used, but the solar cell sheet is covered with epoxy resin and bonded with the PCB circuit board.

Application notes

The size of the solar panel can be customized according to the size required by the customer. The working voltage and working current can be customized. Generally, the epoxy solar panel is used to charge the battery of solar charger, solar light, toy and other small solar application electronic products. The working current is measured in the simulated standard light intensity. The standard test conditions are 1000 W/M 2, 25 ° C, and AM 1.5 conditions. The voltage and current emitted will change with the light intensity of the day. In sunny days, the power generated by the solar panel can be calculated in 4 hours.

Product Usage

Epoxy solar panel is an accessory for solar products. It can charge battery or directly connect load. It can be used in solar lawn light, solar floor lamp, solar garden lamp, solar charger, solar street sign, solar road stud, solar traffic sign, solar flashlights, solar toys and other small electrical products. Medium or large-size solar panels are generally encapsulated in a laminate way. Only solar panels with too small size and a power of only a few watts will be made into epoxy solar panels. Because laminated solar panels have a longer life than epoxy solar panel.

Advantages and Disadvantages of Epoxy Solar Panel

The epoxy solar panel has the characteristics of high production speed, pressure and corrosion resistance, beautiful appearance and low cost.

However, its disadvantage is that the lifespan of the epoxy solar panel is shorter than that of laminated solar panels, and usually the lifespan is only about one year. If it is often exposed to the outdoors, the surface of the epoxy solar panel will become whitish and yellow, which affects the appearance. Therefore, if you want a long-life solar panel, you better choose glass laminated solar panels, ETFE or PET laminated solar panels.
