Product Description

1. Each solar cell is in new condition and not susceptible to micro-crack

2. A proprietary anti - reflective coating provides superior color uniformity

3. Laser - cut for exacting measurements and precision

4. Can be incorporated into several different devices

5. Simple to install or add to your existing product.

6. Small space required for installation.

7. Ready to use, they require no frame or special modifications.

8. For connection, just solder or crimp to the copper tape.

9. Light weighted, very strong and weather resistant.

10. Ideal for OEM and hobby applications.

Basic principle:

(1)The solar panel voltage is best to be 1.5times higher than the storage battery, in order to fully charge the

battery, such as: 3.7V Lithium Battery ===== 3.7*1.5=5.55V. =====> The optium voltage for solar panel

charging this lithium battery is 5.5V, you can choose 6V. Voltage lower than 5V is not a good idea for fast

charging;

12V Lead acid battery ==== 12V*1.5=18V ====> The optium voltage for solar panel is 18V, 17.5V is also

OK. But voltage lower than 17V will not be a good idea for fast charging.

(2) The voltage of solar panel is not the higher, the better, because during our R&D, we must consider the

charging current, and the battery protection. If the charging voltage is too high, the battery might be

damaged. And when the voltage is too high, the charging current would be weak, and the charging speed

would become too slow.

3.7V Lithium Battery ===== The solar panel voltage better not be higher than 6V.

12V Lead acid battery ===== The solar panel voltage better not be higher than 18V, because of the above

two reasons.
