What Is the Methodology Hub For?
The Methodology hub organizes the trust documents behind Solar Panel Angle Calculator. It helps users find the calculation method, PVWatts comparison, version history, source notes, editorial policy, privacy policy, and disclaimer from one clean page.
The methodology hub exists because calculator pages need visible assumptions. Solar angle estimates use latitude, hemisphere, roof pitch, azimuth, season, date, time, and mount context. Those estimates are educational planning outputs. They are not engineering approvals, permit approvals, production guarantees, or utility interconnection decisions.
Which Methodology Page Explains the Calculation?
The Solar Angle Calculation Methodology page explains formulas, inputs, outputs, solar-position logic, PVWatts comparison, roof constraints, country rules, and model limits. That page owns the full calculation method.
Read the full method here: Solar Angle Calculation Methodology.
The full methodology page defines fixed tilt, seasonal tilt, monthly tilt context, solar azimuth, solar elevation, solar zenith, incidence angle, roof pitch, and mount type. It also explains why NREL, NOAA, DOE, OSHA, and local-code context matter for authority.
Which Trust Pages Support the Methodology?
The trust page set separates calculation logic from privacy, editorial, and disclaimer rules. Each page owns one trust function so users and search engines can understand the site structure.
Use these trust pages:
- Privacy Policy explains calculator inputs, cookies, analytics, retention, and user rights.
- Disclaimer explains educational-use limits, safety boundaries, and country-specific rule variation.
- Editorial Policy explains source hierarchy, corrections, AI-assisted drafting limits, and duplicate-intent control.
- PVWatts Comparison explains how this site differs from production modeling.
- Calculator Version History records material calculator and content updates.
How Are Source Limits Handled?
Solar Panel Angle Calculator uses source hierarchy to keep solar calculation claims separate from legal, code, safety, and installation claims. Government and national-laboratory sources anchor technical explanation, while local authorities control project approval.
NREL and NOAA sources support solar geometry and solar-position explanation. DOE sources support home solar planning context. OSHA sources support safety boundaries. Electrical and building code references support jurisdictional limits. None of those sources make Solar Panel Angle Calculator an installer, engineer, utility, or permitting office.
