A typical commercial solar installation requires about 100 sq ft per kW. A 500kW system needs approximately 50,000 sq ft of usable roof space. Most warehouses over 50,000 sq ft have sufficient space for a significant solar installation.
Warehouses and distribution centers are among the best candidates for commercial solar. Their large, flat rooftops provide unobstructed space for solar arrays, while high electricity consumption from lighting, HVAC, and material handling equipment creates substantial savings potential. Demand charge reduction through solar+storage can save an additional 20-30% on peak charges.

Interconnection capacity in industrial areas
A typical warehouses & distribution project is 200-1,500 kW. At the small end of that band it models at $1.55 per watt installed; at the large end it falls to $1.07 per watt, both before project-specific incentives. Scale drives that gap more than sector does: NuWatt's pricing applies a documented volume discount as system size rises.
| System Size | Size Tier | Modeled $/W | Installed Cost | After 30% §48E |
|---|---|---|---|---|
| 200 kW (low end) | Mid-Size Commercial | $1.55/W | $310,200 | $217,140 |
| 1,500 kW (high end) | Large-Scale Commercial | $1.07/W | $1,599,000 | $1,119,300 |
Installed cost before project-specific incentives, from NuWatt's commercial pricing model (reviewed quarterly). The §48E column assumes the 30% base credit with prevailing-wage and apprenticeship compliance and no bonus adders. Full method, cost per square foot, and $/W by state are in the commercial solar cost guide.
Modeled scenario disclosure
The profiles below are planning scenarios built from current market pricing, utility, incentive, and production assumptions. They are not verified NuWatt customer projects or guaranteed outcomes. A real proposal requires site, structural, utility, interconnection, financing, and tax-eligibility review.
System Size
500 kW rooftop
Net cost after §48E + MACRS
$291,518
Annual Savings
$85,000
Payback Period
3.4 years
Payback is computed, not asserted: 500 kW at the modeled $1.12/W is $559,000 installed, less a 30% §48E credit of $167,700 and a first-year MACRS tax shield of $99,782 at the 21% corporate rate, giving $291,518 net against $85,000 a year. State incentives, SREC or tariff revenue, USDA REAP, and demand-charge savings are all excluded, so a real project in a high-incentive state pays back sooner than this.

What the result includes
No state-average price, electric rate, production factor, escalation, or tax rate is used. Section 48E values follow the IRS source verified 2026-08-06; the depreciation line uses the current 100% first-year rule for eligible property and your entered tax rate. Review the IRS credit page.
Replace placeholders with a facility-specific model
NuWatt will use your interval data, utility tariff, roof or site geometry, and an engineer-reviewed scope.
100-500 kW
Customer-facing sustainability, parking canopies, and SREC revenue for retail businesses.
250-2,000 kW
Process energy offset, demand charge management, and energy resilience for manufacturers.
