How it Works

Use our interactive graphic to learn more about how solar can work for your commercial or industrial business.


1. Solar Array

Your business’ solar panels use the sun’s energy
to produce direct current (DC) electricity


2. Inverter & AC Panel

The inverter converts the DC electricity to alternating
current (AC) electricity and sends it to your standard AC
electrical panel.


3. Utility Meter

Solar electricity used by your business is electricity you do
not purchase from the utility grid.


4. Electric Grid

Your solar system works in coordination with the utility
grid. Any demand that is not met by your solar array
is supplied by the grid. Any excess solar electricity that
is not used at your facility will be sent to the grid.


5. Monitoring

Track your system’s production using an online
monitoring portal which is linked directly from your

Why Should Your Company
Switch to Solar?

As a business owner in Illinois, you can take advantage of several benefits by switching to solar:


Switching to solar means owning your company’s energy source, allowing you to lock in power generation and lower your exposure to the ever-rising utility costs. Since cash flow is essential to businesses, the money you save with solar lets you invest in your company.


Solar is a low-risk investment with an impactful ROI thanks to annual savings. A low, essentially fixed energy rate for the 25+ year lifespan of your array, a manufacturer’s warranty on panels, and our service team’s operations & maintenance plans protect your investment.


When you invest in solar, your company demonstrates a commitment to clean energy sources and protecting our planet’s future. You can also strengthen corporate leadership by installing EV charging stations.

Residential Solar Installation in
Marion, IL

Several components work together in a solar PV (photovoltaic) system to power your home with clean and sustainable energy. A connected set of panels, called the solar array, harvests the sun’s energy during the day. Then, an inverter transforms the clean energy into usable electricity to power air conditioning, appliances, and more.

If your system produces more energy than needed to power your home, it goes to the local power grid. In return, the utility company gives you a credit to use during the night hours through net metering. You can track this process and system performance online anytime.

Check out our interactive graphic to view the residential solar process step-by-step.

when the sun is down

energy production
