Solar Panels can be used as Tables for Kids in Night-Time too. Just make a Folding System and in the Nights, Kids can Study on the Roof.
From March to June the Sun is Very much Perpendicular to the Roof. And As the South Eastern Breeze flow during the Summer, Sitting and Reading On Roof is a cooling Effect as well as Relaxing for the Kids to Study.
Two Solar Lamps on the Solar Panel and they enjoy Studying on the Rooftop, experiencing Free Cool Breeze.
