☀️Solar isn't just having a moment — it's becoming a bigger part of America's energy mix. In the first seven months of 2026, solar produced nearly three-quarters as much electricity as coal, according to recent analysis. And with U.S. electricity demand continuing to rise, every source of reliable generation matters.
The takeaway?
The sun isn't sending us a bill. So let's put it to work. 😎🌞 Ready to turn sunshine into a smarter energy strategy?
☀️ Solar has entered the chat… and it’s bringing POWER.
The U.S. now has enough operating solar capacity to power more than 50 million homes. That’s a lot of sunshine doing a lot of work. And the momentum isn’t slowing down — solar generation is expected to grow significantly in 2026.
Translation? The future is looking pretty bright. 😉 Ready to put the sun to work for your business? Let’s make your energy strategy a little more sun-sational.

If 2027 is your target year for commercial solar, waiting could cost you valuable time. ⏰☀️
Projects that missed the July 4, 2026 safe harbor face a much shorter runway, with the clock running toward December 31, 2027 for full operation. And there’s more to the timeline than construction. Interconnection reviews, grid capacity, equipment lead times and new sourcing requirements can all impact how quickly a project moves forward.
The best time to start planning your 2027 solar project? Now.
EFS Energy can help you navigate the process from interconnection and equipment procurement to construction and energization.

What can commercial solar look like in the real world?
For Wehmeyer Seed in Mascoutah, Illinois, it looks like approximately $30,000 in annual energy savings.
Their 520 kW rooftop solar array is one example of how businesses can turn unused roof space into a long-term energy asset. And that's what we love about commercial solar: it's not just about generating clean energy. It's about creating measurable value for the businesses investing in it.
Your roof could be working harder for your business.

For businesses, energy costs go beyond the monthly utility bill. Fluctuating electricity rates, demand charges and the need for greater operational efficiency are making energy management an increasingly important consideration.
Solar can help businesses generate their own electricity and reduce reliance on the grid. But what happens when the sun isn’t shining? That’s where battery storage comes in. Read more in our latest September blog:

Did you know⁉⁉
The 2026–27 Illinois Shines program year opened with 1,000 MW of new capacity statewide, including a dedicated 180 MW block for Large DG projects—the category where many commercial solar systems fall.
For Illinois businesses considering solar, understanding program capacity and incentive opportunities is an important part of planning the project.
And with incentive programs evolving, timing matters. Have questions about how Illinois Shines could impact your project? We're here to help.
There's a question every commercial property owner should ask before signing a solar contract:
👉 How much interconnection capacity is available at my property?
Every utility feeder has a limit for how much new solar it can accept—and that capacity can have a major impact on your project's timeline and design.
At EFS Energy, we look at interconnection early in the process so you aren't finding out about limitations after you've already committed to a project.
Good solar planning starts before the panels go on the roof.

Big roofs. Big energy needs. Big opportunity for savings.
EFS Energy recently completed solar projects for Jansen Chevrolet, with over $50k in savings.
Their system created an opportunity for long-term energy savings and Renewable Energy Credit income. Commercial solar isn't one-size-fits-all. We design systems around the way your business actually operates.
Could your facility be a good fit for solar? Learn more about the project here: https://www.efsenergy.com/jansen-chevrolet/
If solar is on your 2027 business plan, the time to start planning is now.
Interconnection queues are getting more complicated, equipment lead times remain longer than they were before the pandemic, and new sourcing requirements can affect project eligibility.
The good news? There’s still runway—but waiting too long could make your timeline much tighter.
