Paano Kalkulahin si Solar Panel Sizing
Ano ang Solar Panel Sizing?
Calculates solar panel capacity needed to meet energy requirements. Accounts for climate, season, and system losses.
Pormula
Panel wattage = daily need ÷ insolation ÷ 0.80
Step-by-Step na Gabay
- 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
Mga Nalutas na Halimbawa
Input
5000Wh/day need, 5 sun hrs
Resulta
1000W array
Mga Karaniwang Mali na Dapat Iwasan
- ✕Not accounting for seasonal variation
- ✕Ignoring system losses (20% penalty typical)
Mga madalas itanong
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.
