Juego de 6 mini paneles solares circulares de silicio policristalino, 42x42 mm, 0,5 V, 200 mA.

Polycrystalline silicon solar cell modules are composed of high-efficiency polycrystalline silicon cells, featuring high conversion efficiency and high output power. Good light transmittance: Circular solar panels have excellent light transmittance, effectively absorbing solar energy and thus achieving high cell conversion efficiency. Polycrystalline silicon solar panels are available in six sizes: 30 x 30 mm (L*W) (Voltage: 2V; Current: 20 mA), 42 x 42 mm (L*W) (Voltage: 0.5V; Current: 200 mA), 55 x 55 mm (L*W) (Voltage: 2V; Current: 100 mA), 70 x 70 mm (L*W) (Voltage: 2V; Current: 110 mA), 80 x 80 mm (L*W) (Voltage: 4V; Current: 120 mA), and 90 x 90 mm (L*W) (Voltage: 5V; Current: 100 mA). Each pack contains 6 mini solar panels. Energy conservation and emission reduction: Using solar panels can reduce the use of chemical fuels and help reduce greenhouse gas emissions. High autonomy: Solar panels are not limited by natural conditions and are suitable for a variety of projects. You can use them to build solar models, solar toys, solar displays, solar string lights, and more, according to your preferences. Small solar panels can be connected in series or parallel. You can use two or more solar panels of the same specifications in series or parallel. When connected in series, the current is equal and the voltage is added; when connected in parallel, the voltage is equal and the current is added. You must select the appropriate solar panels according to the voltage, current, and power of the load; in addition, solar panels must be used in conjunction with batteries to store electrical energy.
