Features:

1. High efficiency solar cells ensures high performance pv modules and creat more power in peak hours.

2. 3.2mm high transmissive low iron tempered glass, EVA laminate and water-proof TPT yield long life modules while enhancing cell performance.

3. Bypass diodes to avoid hot-spot effect.

4. Pre-cable with fast-connecting systems for convenient installation.

5. Stable, heavy duty anodized aluminum frames with convenient mounting-access for high wind-pressure and snow load.

6. The backside of frame is equipped with drainage holes in order to eliminate the risk that rain or snow water may accumulate in the frame trough and freeze or even bend the frame in cold

weather.

7. 25-year limited power warranty.

Sinski solar panel offers industry leading high performance and are designed specially to meet our clients' demands for residential, commercial and industrial use from small installations to multi-megawatts power plants.

8. Designed for grid-connected power plants up to 1000VDC.  Ideal for use in the large stand-alone systems for battery charging or water pumping as well.

    Our company designs and produces small solar panel with different specification and size. We utilize high transparent epoxy resin to encapsulate small solar panel and employ high-intensity and anti-distorting PCB board (hard pasteboards and glass fiber boards) as baseboard. We import different famous-brand solar cells (125/156) for solar panel. Our epoxy resin solar panel is UV resistant and yellowing resistant. All of our epoxy resin solar panels are environment friendly and fulfill ROSH directives.

   Small solar panel ranges 0.1W to 2W in general, has different size and shape. It has wide applications and can be used to various electronic products and lighting products. We can design and produce small solar panel and control circuit. Control circuit avoids battery of electronic products and lighting products overcharging and over-discharging.
