EDUCATION: Solar panels are devices that take in daylight and convert photo voltaic radiation directly or in a roundabout way into electricity via photoelectric or photochemical effects, it's perfect instruments for science project. DIY YOUR OWN SMART MODEL: Build your personal powered models, solar toys, photo voltaic lights, photo voltaic displays, charging small DC batteries. It can be utilized for coaching purpose. Many of our customers e from school, colleague, etc. CONNECT SOLAR PANELS IN PARALLEL OR IN SERIES: When the voltage of your photo voltaic panel doesnt satisfy your garage battery, you could take two or more similar photo voltaic panels collectively in series. Such as, two 9V photo voltaic panel connect together in series, so its voltage is 18V. When the voltage of solar panel satisfies your storage battery. In order to rush up the speed of charge, you may take two or extra same photo voltaic panel collectively parallel connection. SOLID & WORK LONG HOURS: High conversion rate, high performance output, fantastic susceptible mild effect, as lengthy as there is sunshine, it would work all the time. The shell is made of tempered glass and plastic yellow frame, which preserve photo voltaic panels, and broaden the life of solar panels. ENVIRONMENTAL PROTECTION: Use solar panels to chop your carbon footprint, since it is inexperienced and renewable energy. Unlike traditional generators, solar power would not release any dangerous carbon dioxide. Perfect for small projects: Such as emergency lights, advertisement lamps, site visitors lights, relatives lights, electrical fans, photo voltaic water pumps, solar road lamps, etc. Category:Solar Panels Max. power: 5W Max. voltage: 10V Current: 220mA Weight: 300g/0 Size: solar panel 14x13cm, fan 12x12cm Colour: black, yellow Material: monocrystalline silicon, plastic Package Contents: 1 * Solar Panel 1 * Exhaust Fan Only the above equipment content, different merchandise should not included.
