Model off-grid solar energy budgets and evaluate relative photovoltaic generation ratios directly in your browser. Sizing off-grid solar arrays requires balancing daily watt-hour electricity consumption against available peak sun hours and inverter conversion losses to prevent deep battery depletion.

This sizing utility models generation and consumption balance using three operational parameters: Primary Dimension (val1, representing daily watt-hour appliance load or energy budget), Operating Coefficient (val2, representing equivalent peak sun hours or solar irradiance coefficient), and System Loss Factor (val3, representing system inefficiency or storage reserve margin). The calculation evaluates the primary proportional energy index as (val1 × val2) / val3, the secondary geometric mean index via √(val1 × val2), and the system distribution ratio as (val1 / (val1 + val2)) × 100.

For example, with a daily appliance demand of 100 Wh, an operating solar coefficient of 20, and a loss margin factor of 5, the primary proportional generation ratio calculates to (100 × 20) / 5 = 400.00, the geometric mean evaluates to √(2000) ≈ 44.72, and the relative energy proportion computes to (100 / 120) × 100 ≈ 83.33%.
