Beyond the Calculator
What a real financial model includes.
This calculator is a starting point. A full Sentinel financial analysis goes deeper: actual utility rate data for your account, site-specific solar production modeling, NOI improvement for income-producing properties, system sizing based on your roof and usage, and a full year-by-year projection over 25 years.
System sizing
Right-sized based on your actual energy consumption and roof/land constraints — not a generic estimate.
NOI improvement
For income-producing properties, we model the effect of reduced operating expenses on your net operating income and cap rate valuation.
25-year cash flow
Year-by-year projection of energy savings, maintenance reserves, and cumulative ROI versus alternatives.
Incentive qualification review
We'll evaluate your project for domestic content and energy community eligibility before you commit to procurement.
