The Physics of
Independence.

In the rapidly evolving world of renewable energy, most "calculators" are marketing tools designed by lead-generation companies. They simplify complex technical variables to provide a "best-case scenario" that often collapses under real-world conditions.

1. The Anti-Simplified Approach

At OffgridMath, we reject the simplified model. Our **Engineering Model v4.2** accounts for the multi-variate physics that actually drive ROI: module temperature coefficients, DC/AC clipping losses, voltage drop, and annual Light-Induced Degradation (LID). We believe that being "off-grid" means you cannot afford for your math to be wrong.

2. Institutional Data Standards

We do not use anecdotal evidence. Our models are mapped against the **National Renewable Energy Laboratory (NREL)** P50 generation datasets and the **Department of Energy (DOE)** solar cost projections. When we estimate utility inflation, we use 20 years of historical **Producer Price Index (PPI)** data to ensure our long-term projections are grounded in macroeconomic reality.

3. Radical Transparency

OffgridMath is an independent data resource. We are not owned by a solar installer or a financial institution. Our code is built to be unbiased, accounting for **Maintenance OpEx** and **Inverter Replacement Costs** that marketing calculators conveniently ignore. We provide the "Executive Risk Assessment" because energy independence is an investment, and every investment has risks.
