Assumption
Assumption
Pmax STC = 200W
No power clipping (which means number of PV modules can be large)
Pout max = 75% of average monthly maximum demand (MD) of power
75% is set by authority
It's the differences to Energy Hub - Step 6 AC Power Constraint
Concept
Concept
Pout max Maximum allowable AC power limit injected into the gird by the authority (W)
f1 DC/AC ratio. Typically, 1.11, refer to Step 1 Choose Inverter (decimal)
Nt ac pwr Total number of PV modules based on AC power limit (units)
Pmax STC Peak power of PV module at STC (W)
6.1 Calculate Pout max
6.1 Calculate Pout max
Pout max = Average Monthly Maximum Demand (MD) Of Power * 75% = 76.52 * 75% = 57.39 kW
6.2 Calculate Nt ac pwr
6.2 Calculate Nt ac pwr
318 units of PV modules can be installed within maximum demand constraints
