learn.whatIsHeading
Calculates solar panel capacity needed to meet energy requirements. Accounts for climate, season, and system losses.
공식
Panel wattage = daily need ÷ insolation ÷ 0.80
단계별 가이드
- 1Daily energy requirement in kWh
- 2Average daily insolation (peak sun hours) for location
- 3Panel efficiency (typically 15-22%)
- 4System losses (inverter 5%, wiring 3%, dirt 2%)
- 5Panel wattage = daily need ÷ insolation ÷ 0.80
풀어진 예시
입력
5000Wh/day need, 5 sun hrs
결과
1000W array
피해야 할 일반적인 실수
- ✕Not accounting for seasonal variation
- ✕Ignoring system losses (20% penalty typical)
자주 묻는 질문
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.
