Calculations for the renewable energy input are complex. The PVWatts Calculator[0] helped determine that a vast array (10,000 m^2) of solar panels at 46% efficiency could produce 5,182,905 kWh per year.[1] Whether that would be sufficient power to grow the plants (using lights casting 303 lumens per watt at 350 mA[2]) is unknown at this time.
