'Earlier this year, Utah became the first state in the country to pass legislation allowing people to purchase and install small, portable solar panels that plug into a standard wall socket.
"When attached outside to the balcony or patio of a dwelling, such panels can provide enough power for residents to run free of charge, home appliances such as fridges, dishwashers, washing machines and wi-fi without spending money on electricity from the grid."
The output of the micro inverter is a 110VAC plug so the current goes into your existing wiring feeding anything plugged in to other outlets on that breaker.
Theoretically, anything that can feed power back into the grid needs an interrupter to protect electric utility workers in the event their side is down. It appears these changes in state laws would allow PV systems producing low voltages to be hooked up to the house wiring. This is attractive for its simplicity and relatively low cost.
Anyone have any knowledge to share?
