Review the preliminary layout with a commercial solar specialist. We’ll confirm roof condition, structural requirements, utility service, and the next feasibility steps.
Analyze a commercial roof
Use the property's quote, production, utility-specific energy value, O&M, tax rate and documented Section 48E eligibility.
Commercial solar ROI compares project-specific annual net benefit with net investment. Enter the installed-cost quote, year-one production, utility-specific energy value and O&M. Apply 6% Section 48E unless the project documents the 30% labor-compliant rate, and enter the taxpayer's own effective rate before showing depreciation tax value. The result remains a planning model, not a quote or tax opinion.

Screen the actual building roof, parking area, or land for preliminary panel count, DC system size, annual production, and confidence evidence before entering economics here.
No account required to see your roof result
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.
Use the contractor's installed cost and the engineered DC system size; do not substitute a statewide price-per-watt average.
Use a site-specific year-one production model and the effective utility-specific value of displaced energy.
Use 6% unless the project supports the 30% rate. Enter the taxpayer's own effective rate before modeling depreciation value.
Confirm O&M, export compensation, demand charges, financing, degradation and interconnection items not included in the simple model.
The arithmetic is transparent, but its usefulness depends on the entered quote, site production, utility-specific energy value, O&M and tax inputs. It is not an engineering report, utility study, tax opinion or financing quote.
