Glossary:

Photovoltaic (PV)
A term used to describe the process of converting sunlight directly into electricity.

Solar Array
A group of solar panels installed together to generate electricity.

Grid-Tied System
A solar system connected to the utility grid. It allows you to use grid power when needed and send excess solar energy back.

Off-Grid System
A solar system that operates independently from the utility grid, with batteries to store energy and often a backup generator.

Battery Storage
A system that stores excess solar energy so you can use it later—like at night, during utility peak demand or during a power outage.

Time-of-Use (TOU) Rates
Electric rates that vary depending on the time of day, which can affect solar savings.

Interconnection
The process of connecting your solar system to the utility grid.

Kilowatt (kW)
A unit of power that measures how much electricity is being used or produced at a given moment.

Kilowatt-hour (kWh)
A unit of energy that measures how much electricity is used over time. This is what you see on your electric bill.

System Size
The total power capacity of your solar system, usually measured in kilowatts (kW).

Production
The amount of electricity your solar system generates, typically measured in kWh.

Monitoring
A system (often an app) that lets you track your solar production in real time.

Commissioning
The process of turning your system on after installation and approvals are complete.
