Twenty four US states are now considering legislation to allow small, plug-in solar power systems that connect directly into a wall socket. (www.nytimes.com)

I'm a little wary of plug-in solar in the US. Some of the bills propose allowing 1200 watt panels which can overload wiring depending on what else is on the circuit and how in the wall wiring is run. Limiting plug-in panel wattage to, say, 400 watts might be necessary

No there is a real concern there. Suppose you have a daisy chain that goes breaker - PV panel - load. Say you have 20A draw on the load - enough to trip a 15A breaker, but the PV is providing 10A. In that case you only have 10A at the breaker, but your wires will be significantly over-current.
