There are two main types of solar panels: monocrystalline, and polycrystalline Each type has unique characteristics and advantages.

Monocrystalline panels are made from a single crystal structure, which makes them highly efficient and space-saving. They are easily recognizable by their black color.

Monocrystalline panels are generally the most efficient, as they have a higher power output per square foot compared to polycrystalline and thin-film panels.

Solar cells generate electricity through a process called the photovoltaic effect. When sunlight hits the solar cells, it excites electrons in the cells, creating an electric current.

Sunlight consists of photons. When these photons strike the solar cell, they knock electrons loose from the atoms in the semiconductor material. This creates an electric current.
