No, if the panels are on rooftops, and the electricity is mostly used in the same building, you have the same net thermodynamic effect of the sun hitting the building. No additional entropy is generated. If cities at large become net exporters of electricity it would in some small part alleviate heat bubbles. If the panels are next the the city, you do concentrate heat more in the city as electric is delivered, but no more than electric supplied and consumed from non solar sources. If the panels are adjacent to the city, you again alleviate the heat bubble to some small extent because you're cooling one area and increasing the thermal gradient between the hot city and cooler solar panel farm. I don't know how one would conclude that any of these effects are of a magnitude to "wreck the local ecosystem".
