Subject: A mind-boggling heat problem through a window

This is NOT homework!  I just thought of it myself.

If we have a large window in our home, let's say, four feet by four feet (one 
large square pane), and place a solar panel of the SAME SIZE approximately four 
inches (the ideal placement can be tested)  away from the window inside the 
room, and connect the solar panels to a DC heating element placed on the floor 
of the room, then what is the amount of heat entering the room during peak 
sunlight and is it increased from "normal" radiant heat without solar cells?   
Surely, the radiant heat coming through the glass window is the same as always, 
unchanged, and is either absorbed directly by the materials of the solar panel, 
bounced around the room, or heats the air in the four-inch space between the 
glass window and the solar panel - being absorbed as normal by the room.  Then, 
the electrical activity of the solar panel, which is the same area as the 
window, is converting photons into electricity and then heat, thus generating 
additional heat into the room?  Is this extra energy, above and beyond normal 
radiant energy that would enter the room?  How can this be calculated, for six 
hours of bright sunlight?
