How do Solar Panels Produce Electricity?

Explaining how solar panels help produce electricity for your home.

The sun’s powerful energy has provided energy to millions of homes across America. This green, renewable energy source helps lower energy bills while helping to save the planet.

It only takes about an hour and a half of solar energy hitting the earth’s surface to power the entire world for a full year. Light is simply solar radiation or also known as electromagnetic radiation. The planet will always receive sunlight some areas getting more than others.

With solar technology like solar panels, we can capture this electromagnetic radiation and store it for our use. Why use the old ways of getting electricity when the sun supplies it daily?

There are two main solar energy technologies. Here is how they help produce energy for your home.


Photovoltaics are used in most solar panels. When the sunlight hits the solar panel, the energy from the light is absorbed by the cells in the panel. The energy is then taken and creates energy charges. These charges move in response to the electrical field in the cell.

Each photovoltaic device is known as a cell. Each cell is small and can produce between 1 and 2 watts of power. Each cell is made of different semiconductor materials like Silicon. These cells are roughly about the size of 4 human hairs and are put between protective materials so they can get years of use.

Concentrating Solar-thermal Power

Concentrating solar-thermal power, or CSP, uses a system of mirrors to reflect the sunlight to receivers. These receivers take the solar energy and convert it to heat. The system then takes the heat and produces it into electricity. This energy can be stored for later use. These systems are typically found in very large power plants.

Since these are used are power plants, the thermal energy can be used to spin turbines or power engines. It can also be used in water desalination, oil recovery, food processing, and mineral processing. Many industries will use these instead of the more harmful ways of gathering electricity.

Smaller CSP systems can send power directly to where it is needed. These CSP systems can produce between 5-25 kilowatts of power per dish.

Getting solar panels

There are a number of costs that go into switching to solar panels. You’ll find hardware costs, permitting, financing, and installation fees for when you want to make your switch to solar panels.
