Estimate required panel wattage from daily energy use, effective sun hours and overall system efficiency.
Results are for information and preliminary estimation. For critical technical work, manufacturer data, local codes and qualified professional review take precedence.
Required panel power ≈ daily Wh / (effective sun hours × system efficiency). Season, orientation, shading and local climate can materially change production.
Example: 5 kWh/day with 5 effective sun hours and 75% system efficiency needs roughly 1.33 kW of panels.
Electrical and energy calculations are not final designs by themselves. Load profile, conductor conditions, protection, efficiency and local codes must be considered together. Sorsana tools are intended for preliminary sizing and scenario comparison.
They represent equivalent hours of near-rated solar production, not total daylight hours.
No. This tool estimates panel power. Storage capacity should be calculated separately.
