(July 25, 2015) Reducing
labor costs could help make solar power more affordable.
As the
price of solar panels has plummeted, the amount of solar power being generated
worldwide is soaring. Yet solar still accounts for less than 2 percent of the
world's total electricity capacity. And small wonder. Each square meter of
solar panel generates around 145 watts of electrical power, enough to turn on
just two or three light bulbs.
