Tutorial: How to Use the 3W Solar Panel 145*145MM

The 3W 145*145mm solar panel is ideal for generating energy in small applications or for charging batteries. Useful for beginners and small-scale projects.

What you need

• 3W 145*145mm Solar Panel
• Battery (if needed)
• Voltage Regulator (if needed)
• Connection Cable

Steps

1. 1. Check the output voltage on the datasheet.
2. 2. If necessary, connect the panel to a voltage regulator.
3. 3. Connect the voltage regulator to the battery.
4. 4. Connect the solar panel to the voltage regulator.
5. 5. Ensure that the wires are well soldered and stable.
6. 6. Mount the system in a place with plenty of solar exposure.
7. 7. Check the operation regularly.
8. 8. In case of problems, check the connections and the position of the panel.

Mini project

Build a small power supply system for a relay. Connect the solar panel to a 5V voltage regulator and then to a relay. In 30 minutes you can have a working system.

Common mistakes

• Connect the panel directly to a sensitive component without a voltage regulator.
• Ignore the optimal solar position.
• Do not check the connections regularly.
• Omit risk protection.

Recommended accessories

• 5V voltage regulator
• 18650 LiPo battery
• relay
• connection wire

Frequently asked questions

Does the panel work with any type of battery?
Check the datasheet for the output voltage. Some batteries may not be compatible.

How long does it take to charge a battery?
This depends on the amount of solar energy. Check the datasheet for the charging capacity.

Can it work in shade?
Productivity decreases in shade. Position it in a place with maximum sun exposure.
