How it Works

Your St. Louis small business solar array starts producing clean electricity as soon as the sun shines. During the day, your solar panels generate power to directly offset the energy your business would normally purchase from the utility. Any extra electricity your system produces flows back to the grid, earning you credits on your utility bill through a process called net metering.

This ensures you get the full value of your solar energy, even when your building doesn’t use all the power your system produces. With real-time monitoring, you can check how much energy your solar system is producing and track savings at any time.

1

1. Solar Array

Solar panels capture sunlight and convert it into direct current (DC) electricity, which flows into your building’s electrical system.

2

2. Inverter & AC Panel

The inverter transforms that DC electricity into alternating current (AC) electricity—the type your business uses to power equipment, lighting, and other operations.

3

3. Utility Meter

As your business uses solar energy, you reduce the amount of electricity you need to buy from the utility, lowering your monthly bills.

4

4. Electric Grid

Your solar system works alongside the utility grid, automatically drawing additional electricity if your building needs more than the system is generating. Any excess power your system produces gets sent back to the grid, earning you bill credits through net metering.

5

5. Monitoring

Your system comes with an online monitoring portal that lets you track your energy production and performance 24/7, so you always know how your solar investment is working for you.

Financing & Incentives

Switching to solar in St. Louis is more affordable than ever, thanks to incentives and financing options. Your business could qualify for the 30% Federal Investment Tax Credit (FITC) and accelerated depreciation. We can estimate your savings with a custom quote.

"To be honest, I was a little skeptical of solar at first. I didn't know if it would be a good fit for our organization as a manufacturer. I had a lot of questions and StraightUp Solar was able to answer those questions well... We developed trust so decided to move forward with StraightUp Solar. We needed a lot of help and StraightUp Solar was there to walk us through the process. It is a complicated project because you're working with utility providers, municipalities, raw material suppliers and StraightUp Solar was able to lay out a plan for us."

Illinois Manufacturing Company
"The other really positive thing about StraightUp Solar is you have this big project, and when it's done you might have a sense of 'What do I do next?' They offer help after the project is implemented. They monitor our solar array to make sure it's generating power it should generate, they do regularly planned site visits to make sure everything's functioning. If I have questions I know I can call them. It's not one of those scenarios where they do the project and then they're gone. They're invested in us as a company and they care about our success."
Lucas R.Forge Resources Group

“We were looking at putting in a larger system and from the first encounter with StraightUp Solar they knew all of the regulations and steps our system would have to adhere to. Not only were they incredibly knowledgeable about the entire solar process, but they were also friendly and easy to work with.”

"I have had the pleasure of working with StraightUp Solar for my commercial solar installation at Mountain Top Motor Co. I am very in-depth when it comes to interviewing companies to do business with. I asked a lot of hard questions and I wanted more information than your typical consumer. David at StraightUp Solar not only answered all my questions but taught me some things along the way. StraightUp Solar knew the equipment and the needs of my building more than any other company. They really put a lot of effort into building a quote and system even before a contract was awarded. Through the installation they were great communicators and everything went smoothly. Very impressed with the entire process."
