How are solar panels rated? When a panel is listed as 11kW, how long does it take to produce that amount?

Here is the one I’m looking at: http://www.affordable-solar.com/asgpower-10920-watt-kyocera-grid-tied.htm Does it produce 11kW daily, monthly, annually? Or is that number something totally different?

Does anyone know if solar photovoltaic panels need to be UL listed in California for residential installation? Does a UL listing affect state or federal rebates? Are there any insurance issues with UL or non-UL PV panels installed in California?
