It's easy to demonstrate how alternative energy can be used effectively! This kit makes it a breeze. The zero-emissions house comes as a kit and can be assembled very easily thanks to the detailed instructions. The solar cell mounted on the roof captures sunlight and charges a battery. This battery powers a built-in LED that automatically turns on in the dark. The included circuit board is already pre-soldered and connects to the switch, LED, and solar panel. Therefore, no electronic knowledge is required for this kit. Instead, it aims to impart valuable educational knowledge that can also be applied in everyday life. Ideal for schools and extracurricular institutions, workshops, or simply to build a great model at home.
