how it works

How a Solar System Works

Despite their complex technology, solar systems themselves are streamlined appliances that convert sunlight to electricity. PV panels expose electrons to photons of light, increasing the energy state of the electrons. The surplus energy of these electrons is harvested by the panels as DC power. This DC power is then converted to AC electricity by a small box called an inverter, which subsequently feeds the building. The creation of this electricity is efficient and reliable, and makes no pollution or noise.

Residential and commercial solar systems are mounted on the roof or other available space on the property, and then interconnected to your utility grid. This grid-tie allows your system to send any unused solar electricity into the utility grid. This process of distributing excess energy turns your utility meter backward, giving you free energy credits that may be used at any time, day or night.

Typical Components of a Solar System

Solar Cells

Solar cells are the building blocks of a solar energy system. Made from silicon ingots, these cells convert light energy into electricity by exposing electrons to photons of light, increasing the energy state of the electrons.

Solar panel

Solar panels are made up of 70-90 solar cells arranged upon a singular plane. Each cell is configured together and combined into a single output on the back of the panel.

solar array

The solar array denotes the entire solar face of your system, ranging anywhere from 15 to 1000 panels. The output on each panel is combined together to make a single line that takes the DC solar power to the inverter.

Inverter

An inverter is an appliance that converts the DC power generated by the solar panels into AC electricity that can be used by your building. An inverter is mounted near your utility meter and contains a monitoring system to ensure the efficiency of your system.

Utility Meter

Your utility meter records how much electricity you consume from your utility provider. Your solar system will turn this meter backwards as it produces electricity for the grid.

Utility Grid

The utility grid is the system that delivers electricity to your surrounding area from the utility provider's power plants. By installing solar, you will also be contributing your excess electricity to the grid for others around you to use.
