Central Hudson Gas and Electric raised its per-kWh delivery charge on July 1, 2026, and another increase is already scheduled under the three-year rate plan the New York State Public Service Commission approved in 2025. At approximately 18.9 cents per kWh today and climbing roughly 3% each year, the electricity a Hudson Valley business consumes in 2030 will cost meaningfully more than it does right now. That compounding trajectory is one reason the ROI math for commercial solar looks different in 2026 than it did just a few years ago.
The other reason is the changed federal incentive landscape. Since 2009, Lighthouse Solar has worked with schools, medical buildings, manufacturing facilities, government facilities, and commercial solar developers across the Hudson Valley. The financial questions we hear from business owners today are sharper than they used to be: not “does solar pencil out?” but “exactly how does it pencil out, and what does the first year look like?” That’s the question this post is built to answer.
How Commercial Solar ROI Actually Works
Commercial solar return on investment has three components that work together, and conflating it with residential ROI leads to bad decisions. Homeowners recover their investment through avoided utility costs alone. A business adds a second layer: direct tax benefit recovery in the first year or two that can return a substantial portion of the capital before the system has offset a single decade of electricity bills. The third layer (the residual value of a system still producing power well past payback) represents pure gain.
The payback period shrinks because the federal Investment Tax Credit and bonus depreciation together return a large portion of the system cost in year one. The effective net cost the business must recover through electricity savings is far lower than the gross installation price. And every year Central Hudson rates rise, each kilowatt-hour the system offsets becomes worth more. ROI improves as the system ages, not the reverse.
The Federal Incentive Stack for Commercial Solar in 2026
Two federal mechanisms drive the bulk of the first-year financial return. Understanding each one precisely matters more than a general awareness that “tax incentives exist.”
The Section 48E Investment Tax Credit
The Section 48E commercial Investment Tax Credit (ITC) is 30% for systems placed in service by December 31, 2027. The July 4, 2026 safe harbor construction start deadline has passed, so businesses can’t lock in the credit through that route. Systems completed and interconnected before the end of 2027 can still claim the full 30%. That window is real but not unlimited. Permitting, engineering, and interconnection each take time.
The ITC is a dollar-for-dollar reduction in federal tax liability, not a deduction. On a $500,000 installation, the 30% credit is $150,000 directly off the tax bill. For most commercial buyers, this is the single largest financial event in year one.
One compliance note: for systems at or above 1 megawatt, the 30% rate requires meeting IRS prevailing wage and registered apprenticeship standards during construction. Most commercial rooftop systems fall well under that threshold and qualify for the full credit regardless, but it’s worth confirming with your installer and tax advisor for larger projects.
MACRS Depreciation & Bonus Depreciation
The One Big Beautiful Bill Act permanently restored 100% bonus depreciation for qualified property acquired after January 19, 2025. A business can now deduct the full depreciable basis of a solar system in year one rather than spreading it over a five-year MACRS schedule.
IRS rules require reducing the depreciable basis by half the ITC value. On a $500,000 system, the 30% ITC is $150,000, so the basis is reduced by $75,000, leaving a depreciable basis of $425,000. At a 24% combined effective tax rate, 100% bonus depreciation on $425,000 produces approximately $102,000 in additional tax savings. Combined with the $150,000 ITC, the total first-year federal tax benefit approaches $252,000 on a half-million-dollar system, leaving a net effective cost closer to $248,000, not $500,000.
New York State Incentives That Reduce Net Cost Further
Federal incentives get most of the attention, but New York layers on several programs that meaningfully improve the numbers for a Hudson Valley business.
NYSERDA administers the NY-Sun Megawatt Block Program, which provides upfront per-watt rebates for non-residential systems up to 750 kW. The rebate is applied by the installer at contract time and reduces system cost before the ITC basis is even calculated, which means it compounds into the federal benefit. These rebates cover the Hudson Valley region across Central Hudson, National Grid, and NYSEG territories. Critically, they decline as each capacity block fills. A business that defers a decision by twelve months may be contracting at a lower rebate level than one that moves forward now.
New York State also exempts the sale and installation of commercial solar equipment from state sales tax, which alone can represent tens of thousands of dollars on a larger system. Separately, New York’s 15-year real property tax exemption under Real Property Tax Law § 487 generally prevents a solar installation from triggering a reassessment on commercial property. Individual municipalities may opt out, so confirming local participation with your tax advisor before proceeding is worthwhile.
What a Realistic Payback Period Looks Like for a Hudson Valley Business
The mechanics become clearer with a representative example. Consider a 100 kW commercial rooftop system in the Central Hudson service territory, which covers Poughkeepsie, Newburgh, Beacon, Kingston, and surrounding areas.
A rough working model for illustrative purposes:
- Gross system cost: $250,000
- NY-Sun Megawatt Block rebate (estimated, subject to current block availability): reduces cost before ITC calculation
- 30% Section 48E ITC: approximately $75,000 direct tax credit
- 100% bonus depreciation on 85% of system cost at 24% effective rate: approximately $51,000 in year 1 tax savings
- Combined first-year federal tax benefit: approximately $126,000
- Estimated net effective cost after federal benefits: approximately $124,000 before state rebate
At 18.9 cents per kWh and a 3% annual rate increase, annual electricity savings from a properly sized 100 kW system can reach $20,000 or more depending on consumption profile. That points to a payback period in the range of five to seven years on the net effective cost after incentives, with a system warrantied to perform for 25 years. The remaining 18 to 20 years of operation represent pure avoided cost.
Net metering under Central Hudson allows commercial customers to receive bill credits for excess generation at the retail rate, though the billing structure matters. A business on a demand charge schedule, a time-of-use rate, or a standard commercial rate will see different annual savings numbers. System sizing should be driven by actual consumption data and the specific rate structure, not square footage or a rule-of-thumb watt-per-employee formula.
For businesses with significant peak demand exposure, a solar plus storage system can shift load away from the highest-cost periods in ways that affect both the upfront investment and the long-term return.
Variables That Affect Your Specific ROI
No two commercial solar projects produce the same return. The inputs vary by building and by business.
System Size & Consumption Match
A properly sized system offsets the highest-value portion of the utility bill first. Bigger isn’t always better if the system generates more than the business can use or credit. Sizing starts with twelve months of actual consumption data, not an estimate.
Tax Rate & Credit Utilization
The dollar value of both the ITC and the bonus depreciation deduction is a direct function of the business’s effective combined federal and state tax rate. A higher combined rate means a larger year-one benefit and faster payback. Businesses that can’t absorb the full credit in one year may be able to carry it forward. This is worth reviewing with a tax advisor.
Financing Structure
A cash purchase captures the full ITC and depreciation benefit directly and produces the cleanest ROI calculation. A solar loan, which we offer in terms ranging from five to twenty years, converts the capital expenditure into a monthly payment that can be structured to come in below the current utility bill from day one. The right structure depends on the business’s capital position and tax situation.
Why 2026 Is a Different Calculation Than 2028 or 2029
The combination of factors driving favorable commercial solar ROI right now isn’t permanent. The 30% federal ITC expires for projects placed in service after December 31, 2027. NY-Sun Megawatt Block rebates decline as capacity fills. Central Hudson rates are rising under an already-approved schedule, so every year of delay is a year of paying more per kWh than the system would have offset. Permanent 100% bonus depreciation is the one federal incentive without a sunset date under current law, but the other three factors are all moving toward a lower net return for businesses that wait.
The honest framing: the ROI calculation doesn’t improve with time for a business that defers.
