Calculates solar panel capacity needed to meet energy requirements. Accounts for climate, season, and system losses.

सूत्र

Panel wattage = daily need ÷ insolation ÷ 0.80

चरण-दर-चरण मार्गदर्शिका

  1. 1Daily energy requirement in kWh
  2. 2Average daily insolation (peak sun hours) for location
  3. 3Panel efficiency (typically 15-22%)
  4. 4System losses (inverter 5%, wiring 3%, dirt 2%)
  5. 5Panel wattage = daily need ÷ insolation ÷ 0.80

हल किए गए उदाहरण

इनपुट
5000Wh/day need, 5 sun hrs
परिणाम
1000W array

सामान्य गलतियां जिनसे बचना है

  • Not accounting for seasonal variation
  • Ignoring system losses (20% penalty typical)

अक्सर पूछे जाने वाले प्रश्न

How much solar is needed for household?

Average home 5kW system produces 6,000-8,000 kWh/year depending on location.

Does weather affect solar output?

Yes significantly; cloudy days 25-50% output; winter 30-50% of summer; location critical.
