What is Solar Electricity?


How Solar Electricity Works

Solar system abstract[/titlezone]

Solar is one of the most accessible forms of renewable energy for a commercial business. Many businesses are installing solar photovoltaic systems in order to create their own solar electricity to offset some of their carbon dioxide emissions and reduce their carbon footprint.

With a Greenzu Power Purchase Agreement (PPA), you won’t be required to manage your solar photovoltaic system, but you may wish to know how solar panels works.

Solar electricity from solar panels

Commercial Solar System Components

Solar Photovoltaic Panels:

Every solar system starts with photovoltaic panels which are made up of individual photovoltaic (PV) cells that capture the sun’s energy and convert it into DC power. These panels are generally installed either on a roof or an adjacent structure. Find out more about the types of solar panels available.

Mounting System:

A mounting system is the structure that supports and secures the solar system. There are numerous mounting styles depending location and where the panels are mounted. Discover more about the available types of installation used for today’s solar systems.


A combiner is the connection device that combines the electrical currents generated by individual solar panels and sends them to the inverter.


An inverter will take the DC power produced by the PV cells and convert it into AC power, the electrical standard for most commercial facilities. Learn more about how solar inverters work.

AC Safety Switch:

This is the disconnect system used to sever the building’s electrical system from the solar electric system when necessary

Electrical Panel:

An electrical panel is required to make the AC power from the inverter available to the rest of the building’s electrical systems.

Utility Meter:

A utility meter is important for measuring the electrical power produced by the solar system and the electricity used by the building. Each month, this shows solar’s benefits.

Utility Grid:

Most conventional solar PV systems are connected to the local utility grid which ensures that you have enough electricity when the building requires more than the solar system can provide.

Remote Monitoring System:

Commercial solar installations generally come with remote monitoring systems that allow solar maintenance personnel to track and measure the electricity produced by the solar system. These monitoring systems also send alarms when the system malfunctions or when production levels drop due to external factors.

Balance of System:

This portion of the solar system includes every other miscellaneous part, such as wiring and so on.
