How does solar work?

When light shines on a photovoltaic (PV) cell – also called a solar cell – that light may be reflected, absorbed, or pass right through the cell. The PV cell is composed of semiconductor material; the “semi” means that it can conduct electricity better than an insulator but not as well as a good conductor like a metal.

How do solar panels generate electricity?

The sun emits tiny particles of light called photons. When these photons hit the solar cells in the panel, they start the process of generating electricity. Solar panels absorb sunlight through their surface. The material in the solar cells, typically silicon, is specially designed to capture as much sunlight as possible.

What is a solar module?

A module is a group of panels connected electrically and packaged into a frame (more commonly known as a solar panel), which can then be grouped into larger solar arrays, like the one operating at Nellis Air Force Base in Nevada.

How do solar panels absorb sunlight?

Solar panels absorb sunlight through their surface. The material in the solar cells, typically silicon, is specially designed to capture as much sunlight as possible. When sunlight hits the silicon, it energizes the electrons within the material. Inside each solar cell, there are many tiny particles called electrons.

What are the parts of a solar module?

A typical solar module includes a few essential parts: Solar cells: We've talked about these a lot already, but solar cells absorb sunlight. When it comes to silicon solar cells, there are generally two different types: monocrystalline and polycrystalline.

Do solar panels save energy?

Cost Savings: After installation, the energy from sunlight is free, which can reduce electricity bills significantly. Energy Independence: Using solar panels reduces reliance on traditional power sources, promoting energy independence. Are Solar Panels Really Clean Energy?
