Вашему вниманию предлагаю тест новой поликристалической солнечной панели KDM 150W 12V при плохом освещении в помещении. Меня интересовало, насколько эффективный поликристалический кремний в условиях плохого освещения. Результат опыта из солнечной батареей смотрим на видео. Не забываем лайкать и подписываться на канал!
Updated with fix. Thanks for pointing that out!!! 
Every hear of “Sol”? Sure you have! It’s our Sun! It sits at the center of our 8 planet solar system, providing us with heat and light. But how does that energy get to us? In this episode of Crash Course Kids, Sabrina chats about the sun; what it is, how it works, and how the energy gets to us here on Earth.
This first series is based on 5th grade science. We’re super excited and hope you enjoy Crash Course Kids!

5-PS3-1. Use models to describe that energy in animals’ food (used for body repair, growth, motion, and to maintain body warmth) was once energy from the sun.
