How to Make a Solar Panel Battery Charger:
With some basic equipment and a bit of wiring, build a solar panel battery charger that keeps small appliances going. The advent of solar energy has made small solar panels readily available in all sizes. Build a solar battery charger as a science fair project to demonstrate the simple process of solar power.
- Instructions
- Put 4 AA batteries into the two battery holders.
- Wire the holders together to make a series connection for the battery charger. Connect one positive wire from one holder to one negative wire of the other. Leave the other positive and negative wires alone for now.
- Join the blocking diode and the battery charger. Use the ringed end. Connect this to the positive wire from the battery holder.
- Connect the other end of the blocking diode to the solar panel.
- Take the negative output of the solar panel, and connect it to the negative wire from the battery holders.
- Charge the solar panel, and watch it charge the batteries.
How Does a Solar Panel Battery Charger Work?
- The Panel's Composition
- The solar panel is composed of blocks of photovoltaic cells, meaning they produce electricity from light. The cells are made of either a "crystalline" silicon or and amorphous silicon--the amorphous panels are the more durable and flexible of the two. The purpose of the cells is to collect photons from the sun's rays and convert them into electrons.
- The Battery's Composition
- Rechargeable battery are made of cadmium or hydrogen, alloy, an electrolyte, and a positive and negative terminal. The chemical reaction between the electrolyte and the battery's cell component produces electrons. The electrons pour out of the battery's negative terminal, travel along your device's electronic circuit, providing it with power, and then return to the battery through the positive terminal.
- Charging
- The battery loses its charge when residual particle from the chemical reaction accumulate on the battery's cells--slowing or halting the productions of electrons. The electricity produced from the solar panel reverses the deterioration of the battery. The current produced by the solar panels draws protons to the battery's cells by attracting them with electrons. The process creates the opposite chemical reaction of a discharge--the cells are restored and the electrolyte reconstructed.
- Discharge
- The battery discharges with use but will discharge on its own. The Chemicals react much slower when not in use but are still active. Heat will speed the discharge while cold will slow it. Rechargeable batteries discharge much quicker than alkalines and lithiums but their ability to recharge gives them their value.
How to Use Solar Battery Chargers for Cell Phones:
A solar battery charger can provide a great deal of flexibility for users of small electronic devices such as MP3 players, cameras and cell phones. Choosing a solar charger for use with a cell phone specifically requires that you think about the size of your cell phone battery, the power connector type used by your cell phone, and the power output of the solar charger. Generally, the larger the solar charger, the faster the batter will charge. The larger the battery, the longer it will take to charge.
- Instructions
- Open the battery case of your cell phone, and take out the battery. Look for the label on the battery that shows its power rating. This will be labeled in milliampere hours, which will show up on your battery as a number followed by the abbreviation "mAh".
- Verify that the solar charger you've purchased has the proper connector for your phone. Generally, different brands of phones have different power connectors. Most solar chargers will have adapters for most to all phone brands, but look at the compatibility list on the packaging of the charger to see if your brand is included.
- Calculate how long you'll need to charge your phone with your charger. Divide the watt rating of the charger by its voltage to determine the amperes per hour it provides (amperes are the units used to rate your cell phone's battery). If your cell phone has a 1500 mAh battery, that means it stores 1.5 amperes. A 2-watt charger at 12 volts, for example, provides .167 amperes per hour. That means you need to connect your phone to the charger in full sunlight for about nine hours to provide a full charge. If you want your phone to charge faster, get a higher-powered solar cell.
- Plug your cell phone into the charger when it is in direct sunlight for the amount of time you've calculated based on the battery of your phone and the power output of your charger.

03-25-2012- Other Thoughts: Delivery was right on time and well packaged. <br/>Sent it to a family member in the Dominican when power goes out. Body is entirely of plastic but appeared to have plenty of solar power potential. Like the idea for USB connection. Will have to wait to find out how it performs.
