How can such a small power be so powerful? Level 0 cells have almost no energy. The power is therefore not strong.
The solar energy it absorbs and converts intoworking efficiency is almost negligible.
Imagine that if you enlarge it 100 times, it can only support public lighting, which is still low power.
