What are Solar Panels?
Solar Panels are photovoltaic modules that convert sunlight into DC electrical energy through semiconductor cells made of silicon. Each cell generates a small voltage and current, and cells are connected in series and parallel to achieve the required panel output voltage and current rating. A common example in Indian school and college science projects is using a 6V mini solar panel to charge a small LiPo cell through a solar charger module and power a sensor circuit without any mains connection.

How to Choose the Right Solar Panels
Choose based on your project's voltage requirement and available sunlight condition. For directly powering a 5V microcontroller or charging a USB device, a 5V panel with sufficient current works in bright sunlight. For charging a 12V battery, use a 12V solar panel through a charge controller to prevent overcharging. Panel wattage determines how fast it charges. One practical tip: always add a solar charge controller between any solar panel and a lithium battery, as connecting directly without protection will overcharge and permanently damage the battery even from a small panel in strong Indian summer sunlight.
