Solar Panels For Homes

How Does Insolation Limit Solar Cell Output?

Take for example a location with an insolation (incoming solar radiation) of 500 W/m2. If I install a solar panel rated at 600 W/m2, will it only output 500?

Yes and the proof of this is the output of solar panels at night. However you have to understand insolation and solar panel ratings.

Solar panels are typically rated in Watts. They are typically rated in strong steady direct sunlight to produce the rated amount of watts (amps x volts) Watts is a rating of power. http://solar.calfinder.com/blog/solar-information/solar-panel-ratings-breakdown/

Insolation is not rated in watts but “The values are generally expressed in kWh/m2/day.” http://www.apricus.com/html/solar_collector_insolation.htm which is a measure of energy not power. The difference is the inclusion of a factor of time plus KW is 1000 times as large as a watt.
