Am I reading this right? That performance is far better than what I excepted. A 2000 m2 sail has a payload of 70 tons and a transit time of 338 days(with aerobraking), sure, that's not that great but the sail is only 45m x 45m and 6 kg(at 3g per m2). Solar Cruiser is 1,650 m2, for reference.

With thin-film PVs added it would give the spacecraft 817 kW of power at 1 AU assuming 30% efficiency and at 500 W/kg it would only add 1,633 kg.
