Just the Facts.

How it Works and Why it Works

Solar energy, often hailed as the "cleanest and most abundant renewable energy source available," offers a sustainable solution to our energy needs. It can be harnessed in two primary ways: as thermal energy or as electrical energy.

Here, we delve into the intricate process of converting sunlight into electrical energy using solar panels, also known as photovoltaic (PV) panels:

  • When sunlight radiates to Earth and onto a solar panel, the energy is absorbed.

  • Solar panels are made of several PV cells, each producing one to two watts of power.

  • Cells are made of semiconductor material containing negative and positive receptors, like a battery.

  • When sunlight hits the PV cell, it releases electrons from the semiconductors, creating a current.

  • Electricity is collected through both sides of the cell and flows out.

  • The amount of electricity generated is dependent on how many cells are in each panel.

Fast Facts

Solar panels are not toxic.

Solar panels contain only materials in “solid state” form, just like the electronic components in laptops and smartphones. They do not contain liquids that can “leak.”

Solar panels are not a fire risk.

Solar panels are made mostly of glass and aluminum and are not flammable. Utility scale solar will comply with the National Electric Code, which regulates electrical safety.
