The Solar PV Tilt Angle by Latitude Sizer computes proportional ratios, geometric root factors, and balance percentages for fixed-tilt photovoltaic array mounting angles.

### Mathematical Evaluation & Formulas The tool computes three direct output metrics from three numeric inputs (V1, V2, and V3): - Array Orientation Ratio: Evaluates parameter 1 multiplied by parameter 2 divided by divisor parameter 3 (minimum denominator 0.01): (V1 * V2) / max(0.01, V3) - Geometric Zenith Factor: Evaluates the square root of the two-parameter orientation product: sqrt(max(0, V1 * V2)) - Proportional Alignment Share: Measures the percentage share of parameter 1 within the combined baseline: min(100, max(0, (V1 / (V1 + V2)) * 100%))

Note on Fixed Solar Tilt Angles: For year-round fixed photovoltaic arrays, optimal annual energy generation is typically achieved by tilting panels at an angle approximately equal to the local geographical latitude facing true South (in the Northern Hemisphere). Seasonal optimization uses latitude minus 15° for summer or latitude plus 15° for winter. This online tool evaluates the three-variable proportional arithmetic defined above.

### Numerical Calculation Example Testing orientation parameters with V1 = 35 (geographical latitude factor in degrees), V2 = 15 (seasonal adjustment angle factor), and V3 = 2 (divisor index): - Array Orientation Ratio: (35 * 15) / 2 = 525 / 2 = 262.50 - Geometric Zenith Factor: sqrt(35 * 15) = sqrt(525) ≈ 22.91 - Proportional Alignment Share: (35 / (35 + 15)) * 100% = (35 / 50) * 100% = 70.00%
