Your math is wrong ... and that's why your citation doesn't bring that up ... (ETA: Worster then my spelting)
1,360 W/m^2 x 0.4 = 816 W/m^2
1,360 W/m^2 x 0.05 = 1,292 W/m^2 ... => ... 1,292 W/m^2 - 200 W/m^2 = 1,092 W/m^2
Sorry ding ... 1,092 W/m^2 at the solar panels will make the Earth hotter than with 816 W/m^2 we get with just desert ground with desert flora ... you're wrong even using average albedo of 0.3 ...
I think you're using Chick's definition of albedo and radiation ... that will make you wrong every time ... she's a total LIAR ... (ETA: Worster then my spelting)

Do solar panels re-radiate ALL the radiation it receives? ... if not, we'll need to see the light curve ... does your paper provide that or do you have a link? ... you need to explain why thermometers at these site do NOT record any temperature changes ... see? ... you have no emperical evidence ... just computer models that DON'T reflect Real World™ conditions ...
This time of year, San Luis Obispo is a better place to be than anywhere east of the Rockies ... bar none ... take a vacation this summer, spend two weeks there, the place will be mostly empty with all the students gone home ... YOU will likely need a wetsuit to swim in the ocean, though this far south we might see the natives splashing around ... that's water straight from the ice fields lining the Gulf of Alaska, not that filthy bathwater there in the Gulf of Mexico ...
Bring your thermometers ... you can test your claims yourself at the solar farm listed in your citation ...
