Bounty from the sky, delivered free to the roof, drives the new cooking economy, and not the laboriously drilled, mined, transported, stored, and distributed fuel from the ground, say, kerosene or natural gas, let alone charcoal, firewood or biomass of any kind.

The electricity generated by a solar photovoltaic (PV) system depends on the orientation and tilt of the PV panels, and in some cases, its ability to track the sun throughout the day. Because photovoltaic panels operate more efficiently when oriented directly at the sun, some systems use solar-tracking technology to increase electricity generation by rotating the panels along one or two axes.
