Solar power how to

What is solar power and how does it work?

Solar power works through Photovoltaic (PV) cells, which convert light into usable electricity. This technology has been around since the mid-1800s and is not as complex as some people might think.

How do solar panels generate energy?

Solar panels generate energy by converting the sun’s photons (or light particles) into an electric current to power homes or businesses. We use the terms “irradiance” or “insolation” to refer to the power density of sunlight on a surface. In layperson’s terms, these values represent a roof’s solar potential. An irradiance map of Mt.

How do solar panels work?

A solar panel consists of multiple smaller components, called solar cells, that do the actual work of converting photons into electrical power. In consumer solar panels, solar cells are made from silicon. Solar cells generate electricity when they absorb photons (these are the energy particles that make up sunlight).

How can solar energy be stored?

This energy can be used to generate electricity or be stored in batteries or thermal storage. Below, you can find resources and information on the basics of solar radiation, photovoltaic and concentrating solar-thermal power technologies, electrical grid systems integration, and the non-hardware aspects (soft costs) of solar energy.

How do solar panels convert sunlight into electricity?

The most common method uses photovoltaic (PV) panels that convert sunlight directly into electricity through a process called the photovoltaic effect. When sunlight hits a PV cell, it’s not simply absorbed as heat. Instead, the energy from the sunlight disrupts the arrangement of electrons within the silicon, creating an electric field.

How does a solar PV system work?

Efficient Solar Generation: Your solar PV system works hard. With net metering, you make the most of every bit of sunlight converted into usable electricity. Supporting Traditional Power: On cloudy days when solar generation might be low, you can pull energy from the grid. It's a two-way street.
