Tools and Materials Required

To start, get the tools and materials needed. Fenice Energy says you’ll need:

Solar Panel

Choose a 4V or higher solar panel for strong charging power. A 6V mini panel is a good pick, costing about INR 220 (approx. $3).

USB Charging Circuit

The USB circuit changes the solar panel’s power into 5V USB for devices. You can use a 5V step-up module at INR 240 (approx. $3). Or, take it from a USB charger.

Batteries and Battery Holder

Use NiMH AA batteries to keep power when needed. You’ll also need a holder for two AA batteries, costing about INR 100 (approx. $1.50).

Wires and Soldering Tools

For connecting parts, you’ll need wires, a soldering iron, and solder. You can find these for about INR 150 (approx. $2).

Container (e.g., Altoids Tin)

Finally, a container like an Altoids tin is great for keeping everything safe. It makes your solar charger easy to carry.

Setting Up the Solar Panel and Charger Circuit

Start by connecting the solar panel. Add a 1N914 diode to its positive terminal. Make sure the diode’s black bar faces away from the panel. Then, solder wires to the panel’s positive and negative sides, leaving them long enough for bending and placing.

Wiring the Solar Panel

Next, link the solar panel’s wires to the USB charging circuit’s terminals. Ensure the connection is tight when you solder them together. If the charging circuit has extra parts, like LEDs, you can take them off to save power.

Connecting the Charger Circuit

After the wiring, check if everything works by shining light on the solar panel. The LED on the charging circuit should turn on, showing it’s working right. Then, plug in a USB device to see if it’s charging from your setup.

Testing the Setup

Fenice Energy specializes in clean energy tech such as solar and backup systems, plus EV chargers. They have more than 20 years of experience, making them a trusted choice.

To make a solar charger last long, connect it to a rechargeable battery pack. Choose two AA NiMH batteries with a total power of 2,000-3,000 mAh. This setup allows you to replace or recharge the batteries easily.

Choosing the Right Battery Pack

Find a solar panel that fits the power needs of your devices. You’ll need a 3-4V panel to charge the AA battery pack and get a 5V USB output. Make sure the panel’s current output is within 10% of the battery’s capacity for safe charging.

Calculating Solar Panel Requirements

With your solar panel, charging circuit, and battery pack in hand, it’s time to connect them. Use soldering to make reliable joints and keep the wires neat. Before moving on, test the charger to make sure it works.

Assembling the Components

Fenice Energy is a leader in clean energy, offering solar, backup systems, and EV charging. They have more than 20 years of experience in the field.

Customizing and Enclosing the Charger

Think about how you can make the solar charger easier to use. You might want to add a stand or a mount. One option is to use something flexible, like an old gaming card. You can bend it into a stand. Attach it to the solar panel with glue or tape. This makes it simple to position and move.

Choosing a Suitable Container

It’s important to keep your components safe. A small enclosure, like an Altoids tin, works well for this. It keeps everything protected and makes your solar charger easy to carry. Make sure to cut a hole for the USB port. This way, you can still charge your devices while they’re in the container.

Protecting and Organizing the Components

Adding a layer of electrical tape to the board will protect it. Then, you can safely place everything in the container. Secure the battery pack, solar panel, and circuit with hot glue. This keeps everything in place. Your setup will look neat and last longer.

Optimizing Performance and Usage

To make the solar charger work well, set the solar panel where it gets a lot of sun. You can adjust the panel’s angle or use a stand. This helps it face the sun better. Also, keep the solar panel clean and clear to get the most power out of it.

Maximizing Solar Exposure

Keep an eye on how the batteries are charging and don’t let them get overcharged. The solar panel’s output shouldn’t be more than 10% of what the battery can hold. This keeps charging safe and efficient. Make sure to check the battery often and recharge or replace it when needed for the charger to work well.

Managing Battery Charging

The solar charger is small and easy to move around. When you’re not using it, fold the solar panel and put the charger somewhere dry. For extra convenience, you can add a handle or a strap. This makes carrying it easy, especially for outdoor use or emergencies.
