Solar Panel ஐ எப்படி கணக்கிடுவது

Solar Panel என்றால் என்ன?

A solar panel number calculator estimates how many panels are needed based on annual electricity usage, local peak sun hours, and individual panel wattage.

சூத்திரம்

Annual output (kWh) = Panel wattage × Peak sun hours × 365 × System efficiency | Solar insolation varies by location

P: Panel rated power (W)
H: Peak sun hours per day (hours)
η: System efficiency (0.75–0.85)
E_annual: Annual energy output (kWh)

படிப்படியான வழிகாட்டி

1Annual generation per panel (kWh) = Wattage × Sun hours/day × 365 / 1,000
2Panels needed = Annual usage / Annual generation per panel
3UK average: 2.5–3.5 peak sun hours/day
4Add 15–20% for inverter losses and shading
