Know all about Solar Powered Window Charger with Circuit

 

Solar Window Portable Charger contains an ABS plastic case and a solar panel. The PV panel enclosed by silicone pads of ABS case. Solar energy used to charge a phone is the new idea and the XDModo Solar Charger is one of the gadget that uses solar energy for charging purposes. The use of solar energy is not a new technology, but utilizing this solar energy to charge cell phones is a new innovation.

Solar Powered Window Charger

For boosting energy to battery, a mini USB input and USB output ports are present. It contains 1300 mAh Lithium ion battery which can be rechargeable as input and it takes 13 hours to complete its full charging of battery with the exposure of sunlight. It has an output of 5V/500mA at max.

Direct sunlight exposure of mobile for charging does not harm the phone. It only produces energy and charges the device. The electricity produced by the solar energy is utilized by the charger for getting charged itself and later this charged energy will be transferred to the mobile. Finally, the battery gets charged and charges the phone. Solar energy is a renewable power.Here we are explaining about solar powered window charger project.

 Solar Powered Window Charger Project:

The Window solar charger is stuck to the glass of a window as it has silicon pads on the ABS plastic case and this set up uses solar energy to charge your mobiles. In case of the XDModo Solar Charger, its surface will be adhesive and it will get stuck to any glass surface or window and later by keeping towards the rays of the sun the mobile gets charged.

Window solar charger of 0.68-inches of thickness is stuck to the glass window that is present inside with the photovoltaic panels and charging cable is fed to portable device.

Circuit Description of Solar Powered Window Charger

The following diagram contains 48V solar battery charger circuit with low and high cut off features and the below points describes the functioning of the circuit.

An Integrated Circuit IC 741 is configured as a comparator and is appropriately stabilized from 48V high input usingZener diodes and potential divider network across its supply and input pins.

Circuit Diagram of Solar Powered Window Charger

The solar charger circuit diagram is as shown above. The battery cells to be charged shows the circuit module of solar charger with voltage. This is due to 0.3 to 0.4 V drop in voltage across Schottky diode D1. Charge voltage set on P1 extends the limit of voltage of 0.3–0.4 V. Solar cells that are connected in eight series will become the solar panel for the project. The solar panel supplies nearly 140 mA -200mA or more at 8 times 0.45 V = 3.6 V. Instead of a Zener diode we can also take two normal diodes in forward bias direction and cathode that is connected to the ground.

The circuit around T2 observes the Voltage across the batteries. After the voltage gets full charged along with the solar panel, power resistor is switched on and it ends the charging of output solar panel voltage.

Features:

• It consists of built in technology to protect the device from over-charging and over-heating.
• The Window solar charger contains an LED charge indicator on the bottom edge which shows a red light when it is charging and turns green light when its battery is full or the  device is powered up.
• Window clings solar charger is eco-friendly process as solar energy is used for charging and it contains 5.5V and 1800mAh Lithium battery which can be rechargeable with input and USB output cables.

Solar Mobile Charger

Advantages:

• The solar panel stores energy and these solar battery chargers are easy to carry.
• It can be used to charge mobiles, laptops and various electronic equipments.
• Bigger battery chargers are utilized for digital cameras, laptops, MP3 and iPods.
• The main advantage with this solar window charger is that it does not require any external power for charging other than solar energy.
• It is cost effective as the cost is not involved once the charger is purchased.

Disadvantages:

• The solar Window charger requires light to work means sunlight is needed for the device to get charged.
• Efficiency of photo-voltaic panels had increased.
• Charging the equipment with the help of solar window charger takes more time when compared with general charger.

Applications:

• An iPhone and iPad can also be charged by using this technology.
• The solar window charger is easily attachable to the window and the phone is exposed to sunlight and it charges your electronic equipment.
