How Solar Works

Learn more about how solar power works to create and store energy for use in your home or business.

Solar Panel System

A solar energy system is made with multiple components that work together to gather solar energy and convert it into electricity. Learn more about the parts that make the solar panel system by reading below:

Solar Panels

Also known as photovoltaic (PV) modules, solar panels are the energy harvesters in the system. Solar panels for homes, businesses, or other properties are made of solar cells, which absorb sunlight. This absorbed solar energy is converted into direct current (DC) electricity through the photovoltaic effect.

Charge Controller and Battery

A system with energy storage will also send some or all of the DC electricity through a charge controller and then to the batteries. The inverter then converts the DC battery power to AC electricity.


Once the solar energy is converted into DC electricity, it is transferred to the inverter. This piece of solar equipment converts the DC electricity into alternating current (AC) electricity. This is an important part of the solar power process, as AC current is what most household appliances and electronics are powered by.

Electrical Panel

The newly converted AC electricity is then sent to the electrical panel where it will be used by your home or business. In most areas, excess solar can be sent back to the grid for bill credits. Depending on your preference and the options in your area, you may choose to utilize a utility grid connection, battery storage, or both at the same time.

Utility Grid Connection

This option sends excess electricity back to the grid in exchange for compensation through a net metering program, like the one offered by Rocky Mountain Power. Our solar power experts can help you learn more about how this program works.

Energy (Battery) Storage

You may choose to purchase and install a battery, which stores extra energy rather than sending it back to the grid. This is great for powering your property on cloudy days, at night, or when there is a power outage.
