The Solar Water Heater Collector Panel Area & Tank Sizer computes proportional ratios, geometric root metrics, and balance percentages for solar domestic hot water (SDHW) installations.

### Mathematical Evaluation & Formulas The tool computes three direct output metrics from three numeric inputs (V1, V2, and V3): - Thermal Sizing Proportion: Evaluates parameter 1 multiplied by parameter 2 divided by divisor parameter 3 (minimum denominator 0.01): (V1 * V2) / max(0.01, V3) - Geometric Mean Thermal Factor: Determines the root-mean-product of the primary two parameters: sqrt(max(0, V1 * V2)) - Capacity Balance Share: Measures the percentage share of parameter 1 across the combined baseline: min(100, max(0, (V1 / (V1 + V2)) * 100%))

Note on Solar Domestic Hot Water (SDHW) Engineering: Practical solar water heating installations size glazed flat-plate or evacuated-tube collector gross area against storage tank volume (typically 1.0 to 1.5 gallons of insulated storage capacity per square foot of collector aperture). This interactive utility evaluates the three-variable proportional arithmetic defined above.

### Numerical Calculation Example Testing solar thermal parameters with V1 = 60 (hot water consumption factor in gallons), V2 = 40 (collector aperture area factor in sq ft), and V3 = 8 (storage tank sizing divisor): - Thermal Sizing Proportion: (60 * 40) / 8 = 2400 / 8 = 300.00 - Geometric Mean Thermal Factor: sqrt(60 * 40) = sqrt(2400) ≈ 48.99 - Capacity Balance Share: (60 / (60 + 40)) * 100% = (60 / 100) * 100% = 60.00%
