Commercial Solar

Our commercial portfolio is as diverse as the businesses in the Metro East. StraightUp Solar’s commercial solar installers work with small and large businesses across all sectors, such as industrial and manufacturing, government entities, nonprofit organizations, schools, and agriculture.

StraightUp Solar’s commercial solutions are grid-tied, meaning they connect to your utility’s meter for seamless and safe electrical use. A solar PV system captures clean energy from the sun and generates energy for your building’s operations. The solar energy goes to your building first with any excess energy sent out to the grid. By generating your own power during the day instead of receiving electricity from the utility, your business can lower its electricity costs. 

Our interactive infographic explains how a commercial solar system works for your business.

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

Residential Solar Installation in
Metro East  St. Louis, IL

A solar photovoltaic (PV) system consists of several components to provide electricity to your home.  Modules (i.e., solar panels) made of silicon and electrical circuits absorb the sun’s energy during the day. The modules are connected together into solar arrays and wired to an inverter. An inverter transforms the direct energy from the sun into usable, alternating current, electricity to power air conditioning, appliances, and more.

When your solar PV system produces more energy than needed to power your home, the excess energy goes to the utility’s 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.
