solar cell
A solar cell is an energy thief that steals the innocent sunlight of day, only to revert to a mere dark slab by night. It tilts desperately to please its owner’s demands, its output swinging with the whimsical moods of passing clouds. Enduring harsh conditions atop roofs under the guise of environmental virtue, it is an overworked servant. And periodically subjected to the merciless torture known as maintenance cleanings, it remains the tragic hero of renewable energy.
