Review the preliminary layout with a commercial solar specialist. We’ll confirm roof condition, structural requirements, utility service, and the next feasibility steps.

Calculate your ITC stacking, MACRS depreciation, and state incentives. See your net cost and payback period instantly.
A $500,000 commercial solar system can receive up to $350,000 in combined tax credits (70% max ITC), plus $50,000+ in MACRS depreciation value, bringing net cost to under $100,000. Most businesses with 30% ITC + MACRS see 40-55% reduction in total cost.
Use your facility's quote, production model, and utility-specific energy value. The model will not substitute a state average or an invented price.

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.
System Cost x 30% (with prevailing wage) = Base ITC. Example: $500,000 x 30% = $150,000
Domestic Content (+10%): $50,000 | Energy Community (+10%): $50,000 | Low-Income (+10-20%): $50,000-$100,000
Depreciable Basis = System Cost - (ITC x 50%). Apply 100% first-year bonus depreciation. Tax savings = Depreciation x Tax Rate.
$500K system with full stacking: $500K - $250K (ITC) - $87K (MACRS) = $163K net cost (67% reduction)
Start with your system cost, then apply the base 30% ITC. Add applicable bonuses: +10% domestic content, +10% energy community, +10-20% low-income. Then calculate MACRS depreciation on the adjusted basis.
