Calcola quanti pannelli fotovoltaici servono, la potenza di picco in kWp, la taglia dell'inverter e i m² sul tetto in base al consumo mensile in bolletta.
Standard Fotovoltaico (CEI EN 61724): Include un Performance Ratio reale dell'80% (PR = 0,80) per perdite termiche e di conversione.
| Potencia Campo (kWp) | Nº Paneles (500 Wp) | Inversor Nominal | Producción Anual Media | Superficie Mínima |
|---|---|---|---|---|
| 2,0 kWp | 4 paneles | 2,0 kW | 3.000 - 3.400 kWh/año | 9 m² |
| 3,0 kWp | 6 paneles | 3,0 kW | 4.500 - 5.100 kWh/año | 13 m² |
| 5,0 kWp | 10 paneles | 5,0 kW | 7.500 - 8.500 kWh/año | 22 m² |
| 8,0 kWp | 16 paneles | 8,0 kW | 12.000 - 13.600 kWh/año | 35 m² |
For DC and single-phase AC circuits, cross-sectional area S (mm²) = (2 × Length × Current × ρ) / Voltage Drop (V). Always verify that conductor ampacity meets NFPA 70 (NEC Table 310.16) or IEC 60364.
Under NEC and IEC standards, the recommended maximum voltage drop is 3% for branch circuits and 5% total for combined feeder and branch circuits.
