Here at Manual do Mundo, we made, tested, and even compared it to a store-bought one to evaluate its performance. There are different ways to create a solar panel at home, but we'll focus on the simplest: making a string of LEDs. By the way, did you know that LEDs can generate electricity when they receive sunlight? Yes, they can, and we'll show you how! Sounds crazy, doesn't it? But by following the step-by-step instructions, we can make the LED react the way we want and thus create our own solar panel. "But Iberê, are you going to compare this to programming?" Absolutely! Programming is nothing more than a list of commands and tasks that we create for computers to execute. In real life, it's no different; we have a to-do list that we ourselves create and execute. To create and program our homemade solar panel, we will use a high-brightness red LED, 5 mm in diameter and 15,000 millicandelas. Millicandelas is the unit of measurement for the amount of light an LED can emit. Each of these LEDs cost approximately R$ 0.40. Using a multimeter, we were able to determine the electricity an LED can generate, arriving at a voltage similar to that of a battery, although the amount of amperes and electrons is nowhere near what a battery can offer. Using 2 LEDs, we were able to power a 1.5-volt calculator (one battery). With more than 50 LEDs, we lit another LED; however, we were unsuccessful with a DVD motor, which requires very little energy. With the tests performed, we have an idea of ​​how many LEDs we will need to make the homemade solar panel work. Back to building our solar panel, we'll need a plastic cover, a drill, and LEDs that will be attached by soldering. With the "recipe" in hand, it's time to get to work! We want a robust solar panel, so we'll create ours based on one we managed to buy, which provides 6 volts and reaches up to 3 watts. We designed our project on the computer, printed it, and laser-cut our solar panel. Almost 4 hours of work later, we have our solar panel with 200 LEDs.
