| dc.description.abstract | The increasing use of portable electronic devices has created a growing demand for reliable,
portable, and environmentally friendly power sources. Conventional charging methods
depend heavily on grid electricity, which is often unavailable in remote areas and contributes
to environmental pollution. This project presents the design and implementation of a solar
based wireless power charger that utilizes renewable solar energy to charge electronic devices
through both wired (USB) and wireless methods. The proposed system consists of a solar
panel, solar charge controller, 12V battery, DC–DC converters, USB output, and a wireless
charging module. Solar energy is converted into electrical energy using a photovoltaic panel
and regulated by the charge controller to safely charge the battery. The stored energy is then
supplied to USB and wireless charging units, ensuring continuous power availability even
during low sunlight conditions. Wireless charging is achieved using electromagnetic
induction, providing convenient and contactless charging. The system was tested under
different operating conditions, and the results demonstrate reliable performance for low
power devices. Although wireless charging introduces some efficiency losses, the overall
system proves to be portable, eco-friendly, and suitable for off-grid and emergency
applications. This project highlights the feasibility of integrating solar energy with wireless
charging technology as a sustainable alternative to conventional charging methods. | en_US |
