Residential Solar in
St. Louis City & County

A solar PV (photovoltaic) system is a unified network of equipment that powers your home with clean and sustainable energy. The solar array – a connected set of panels – collects the sun’s energy during the day. Then, an inverter transforms the accumulated energy into ready-to-use electricity to power appliances, air conditioning, and more.

Any excess energy goes to the local power grid, and the utility company gives you a credit to use during the night – a process called net metering. You can track your system’s production and efficiency online anytime.

Residential Solar Benefits 


When you own your home’s energy source, you lock in that portion of your energy use and protect yourself against ever-rising utility bills.


You can store your clean energy for later use through our battery options. When the power grid goes down, your home does not. Consider pairing your solar + battery solution with a smart panel for total energy control. You can also rest assured knowing that if something does happen, our full-time service department has your back.

Increased Home Value

Solar installation projects are now viewed similarly to home renovations, like kitchen or bathroom upgrades. Recent studies have also shown that homes with solar sell for a higher value than traditionally-powered houses. StraightUp Solar’s special partnership with Pearl ensures that homeowners can demonstrate the value of their solar investment.

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

Commercial Solar in St. Louis 

St. Louis, MO, business owners can reap numerous benefits from switching to solar, including:


Owning your company’s power source lets you lock in energy generation and helps you become less exposed to rising utility rates. You can use the money you save to grow your business and boost cash flow.


Annual savings make solar a low-risk investment with a significant ROI. A low, essentially fixed electricity rate for the 25+ year lifespan of your array, a manufacturer’s warranty on panels, and operations & maintenance options from our service team protect your investment.


Your company’s investment in a solar system is also an investment in our planet’s future. When you switch to solar, you send a message to employees, potential customers, investors, and the community that you take renewable energy sources seriously. You can also further your corporate leadership by installing EV charging stations.
