Not because solar doesn’t work. Not because the ROI isn’t there.

But because everything around the solar breaks down.

In a recent SunCast podcast episode featuring Aaron Wilson, Co-Founder and CEO of Solar One, a key insight emerged for the industry: solar isn’t the problem—the process is.

The Big Misconception: “Solar Is Too Expensive”

One of the biggest myths in C&I solar is that projects fail due to poor economics.
In reality, many projects are financially viable—and even highly profitable. Some deliver double-digit returns, immediate reductions in operating expenses, and significant operating income increases.

So why aren’t more projects getting done? Because decision-makers never get far enough to act on the opportunity.

The Real Reasons C&I Solar Projects Fail

1. Complexity Kills Momentum

From feasibility studies to provider selection, the process is overwhelming. A standard evaluation involves:

• Energy analysis
• System design and engineering
• Incentives and tax structures
• Vendor comparisons

For most property owners and financial leaders, this isn’t their core business. The resulting friction causes delays or complete drop-off.
The result: “Analysis paralysis.”

2. Too Many Stakeholders, Not Enough Alignment

C&I solar isn’t a one-decision deal. You’re often dealing with property owners, asset managers, finance teams, tenants, and developers. Each has different incentives. If they aren’t aligned, the project stalls. Industry experts note that deals often don’t fail outright—they just… stop moving.

3. Vendor Fragmentation Creates Confusion

There are thousands of solar providers, all with different pricing models, financing structures, and technical approaches. Without a clear way to compare options, decision-makers hesitate—and hesitation kills deals.

4. It Feels Operationally Heavy

Even when the numbers make sense, projects feel like a headache.

• “Will this disrupt tenants?”
• “Who maintains it?”
• “What happens if something breaks?”

This perceived burden often outweighs the perceived upside, especially when relying on disjointed third-party contractors.

5. The Gap Between “Yes” and Execution

Getting initial interest is one thing. Actually closing and deploying? That’s where most projects die. This gap—between evaluation and execution—is one of the biggest bottlenecks in the industry.

The Deeper Insight: Solar Is a Business Process Problem

Here’s the real takeaway from the episode: C&I solar isn’t a technology problem—it’s a workflow problem.
The industry has matured on the hardware side. Panels are reliable, costs have dropped, and incentives are strong. But the soft side—sales, coordination, decision-making, and execution—hasn’t kept up.

What Successful Projects Do Differently (The Solar One Approach)

At Solar One, we’ve structured our entire business to solve these exact bottlenecks. Here is how winning projects make it to the finish line:

1. Treat Solar Like a Financial Asset

Top operators don’t treat solar as just an “ESG initiative.” They treat it like a revenue generator, a cost-reduction strategy, and a balance sheet asset. Designed with financial leaders in mind, commercial solar leverages underutilized roof, land, or parking space to immediately improve financial performance and long-term ROI.

2. Simplify Decision-Making Through Vertical Integration

The easier it is to say “yes,” the more projects move forward. This is why Solar One operates as a vertically integrated self-performing company. By providing development, engineering, procurement, construction, and operations/maintenance (O&M) services all under one roof, we eliminate vendor fragmentation and reduce technical overwhelm.

3. Align Stakeholders Early

Projects succeed when everyone agrees on the outcome from day one. That means setting clear ROI expectations, defining responsibilities, and maintaining transparent communication across finance, operations, and ownership teams.

4. Focus on Execution, Not Just Sales

The best companies don’t just sell solar—they guide projects to completion. Execution is everything. Because Solar One handles everything from initial design to long-term O&M, there is consistency across every step of your project, safeguarding your investment long after the panels are turned on.

Final Thought: The Opportunity Is Massive—If You Remove the Friction

Only a small fraction of viable commercial buildings have solar installed today—even though the economics make sense.

The companies that win in the commercial space won’t just be the ones with the best panels. They will be the ones who make it easiest to go from:

“This looks interesting…” → “Let’s do it.”

The post Why Most Commercial Solar Projects Fail (Hint: It’s Not the Solar) first appeared on Solar One.

The commercial and industrial (C&I) solar market has long relied on a robust financial backbone: the Federal Investment Tax Credit (ITC). This incentive allows businesses to deduct a significant percentage of their solar system costs from federal taxes, making renewable energy projects an attractive financial strategy for many corporations. The Commercial Solar ITC Deadline is rapidly approaching.

For businesses and property owners considering a solar installation, this isn’t just a technical update; it’s a time-sensitive call to action. If you’re ready to secure your financial future before this opportunity diminishes, contact Solar One for a professional estimate and timeline today.

The New Reality: Accelerated Phase-Out and Tightened Rules

Under the recently enacted One Big Beautiful Bill Act (OBBBA), the window to claim the full 30% Investment Tax Credit for your commercial solar and storage project is rapidly closing. The original expectation of a longer, multi-year ramp-down has been replaced by an accelerated cutoff, effectively forcing a much more compact development timeline.

To secure the maximum credit, your project must meet specific “begin construction” deadlines. Missing this critical milestone by mere weeks or months could mean leaving tens, or even hundreds, of thousands of dollars on the table.

In plain English: the financial landscape for future solar projects is about to get significantly more expensive. The certainty the ITC provided is dissolving, making 2025 and 2026 the final, high-value years to initiate your project.

Why the Rush? The Simple Truth About the Deadline

The urgency isn’t about flipping a switch; it’s about meeting a specific, hard-to-hit IRS benchmark known as “Begin Construction.”

To lock in the full credit, your project must officially pass this point by the deadline. For large commercial jobs, this doesn’t mean just signing a contract—it means proving to the IRS you’ve made a genuine, financial commitment.

The Critical IRS Notice 2025-42 Change

The rules for establishing “Begin Construction” were significantly tightened by the IRS in Notice 2025-42, effective for projects starting on or after September 2, 2025.

• For Large Solar Projects (Over 1.5 MW): The popular 5% Safe Harbor Rule (which allowed you to lock in the credit simply by ordering equipment) is no longer available. Now, these large-scale projects must strictly adhere to the “Physical Work of a Significant Nature” test to qualify.
• For Smaller Projects (Under 1.5 MW): The 5% safe harbor may still apply under certain conditions, offering a small grace note for small to mid-size commercial installations.

The critical insight? Getting to the “Begin Construction” stage takes months of complex planning, engineering, permitting, and financing. This new ruling makes the process much less flexible for large projects.

Furthermore, the law includes new constraints around Domestic Content and Foreign Entity of Concern (FEOC) sourcing, which can further impact your project’s final credit eligibility.

The window for planning, procuring, and preparing your project is closing fast. This has led to a massive industry rush, with experts already projecting strained supply chains and extended lead times. Don’t get caught in the bottleneck.

What Happens When the Credit Is Gone?

The end of the 30% ITC will not stop the solar industry, but it will fundamentally change the economics for end-users:

• Higher Net Costs: The out-of-pocket cost of a new commercial system will jump immediately, extending the payback period and reducing the overall lifetime ROI.
• Increased Project Complexity: Developers will need to work harder to find cost efficiencies and leverage smaller state or local incentives to bridge the financial gap.
• Project Delays & Bottlenecks: Expect a final surge as companies rush to meet the accelerated deadlines, potentially increasing equipment prices and lengthening permitting queues.

The Immediate Action Plan for Your Business

Delaying your decision is the same as accepting a lower return on investment. If you are a business owner, property manager, or facility operator, you need to act now:

• Get a Project Quote and Timeline: Engage with Solar One immediately. They can help you model your ROI with the 30% ITC and illustrate the financial penalty of waiting.
• Prioritize the “Physical Work” Test: If your project is over 1.5 MW, understand that the “paperwork” safe harbor is gone. Your timeline must now be entirely focused on getting boots on the ground to meet the Physical Work Test.
• Explore State and Local Incentives: While the federal credit is paramount, check if your state or local utility offers additional programs that can cushion the eventual phase-out.

The financial incentive that has defined the C&I solar industry for over a decade is officially on the runway for its final takeoff. Don’t watch this massive opportunity disappear from the tarmac.
