How Do Solar Panels Work?
When photons hit a solar cell, they knock electrons loose from
their atoms. If conductors are
attached to the positive and negative sides of a cell, it forms an
electrical circuit. When
electrons flow through such a circuit, they generate electricity.
Multiple cells make up a solar
panel, and multiple panels (modules) can be wired together to form
a solar array. The more
panels you can deploy, the more energy you can expect to generate.
Solar panel applications
1. Living house and home building
2. Office building, factory and warehouse
3. shopping mall, vanue, stadium and so on
4. Power station, field operation some huge engineer construction.
