Solar panels?
Wu Heng pondered for a bit before realizing it referred to solar panels.
It's actually quite common. The street lights in the housing estate are of this kind.
But for ordinary people, there is not much use for it.
He had seen some videos about these solar panels being laid on rooftops to provide electricity for the entire building.
However, such things are usually set up in villas or bungalows.
In places like housing complexes, it's not possible to install solar panels on a large scale.
It's understandable that shelters want to attack such factories.
In the current situation, most shelters are having power supply issues.
Without electricity, modern people's lifestyle is not much different from primitive people, and solar panels are a good choice.
At least it's simpler than wind power or thermal power generation.
"There's a factory like this locally?" Wu Heng asked.
