About this app
Ground Mount Calc helps solar energy professionals design optimal ground-mounted PV array layouts with precise row spacing and inter-row shading analysis. FEATURES: - Calculate optimal tilt angle based on latitude - Row spacing analysis to avoid inter-row shading - Shadow length calculation based on sun elevation - Ground Coverage Ratio (GCR) optimization - Total area needed for your array layout - Inter-row shading pass/fail check - Save calculations to history - Export professional PDF reports - Works completely offline INPUTS: - Site latitude - Panel height and width - Tilt angle and azimuth - Number of rows - Ground coverage ratio (0.3-0.6) - Minimum sun elevation angle OUTPUTS: - Optimal tilt angle - Required row spacing - Total array depth and area - Panel depth at tilt - Shadow length - Actual GCR - Inter-row shading status Part of the SolarTools suite of professional solar energy calculators.
