🔧 Typical Charging Setup:
-
For 3.7V Li-ion: Use a TP4056 charge module with protection
-
For 6V Lead-Acid: Use a 6V solar charge controller
-
For 5V USB devices: Use a 5V regulator (e.g., LM2596, MT3608, or 5V buck converter)
⚠️ Important Notes:
-
Voltage output varies. Solar panel output voltage and current depend on sunlight intensity. In full sun, Voc may exceed 8V.
-
Charge controller recommended. For battery charging, always use an appropriate charge controller to prevent overcharging.
-
Diodes. A blocking diode (e.g., 1N5819 Schottky) is recommended to prevent reverse current at night.
-
Weather resistance. Epoxy encapsulation provides splash resistance but the panel is not fully waterproof. Avoid prolonged submersion.
-
Orientation. For maximum output, angle the panel toward the sun (typically south in the northern hemisphere).
