Solar energy | Definition, Uses, Advantages, & Facts | Britannica

The potential for solar energy to be harnessed as solar power is enormous, since about 200,000 times the world''s total daily electric-generating capacity is received by Earth every day in the form of solar energy. Unfortunately, though solar energy itself is free, the high cost of its collection, conversion, and storage still limits its exploitation in many places.

Dish/Engine System Concentrating Solar-Thermal Power Basics

Dish/engine systems use a parabolic dish of mirrors to direct and concentrate sunlight onto a central engine that produces electricity. The dish/engine system is a concentrating solar power (CSP) technology that produces smaller amounts of electricity than other CSP technologies—typically in the range of 3 to 25 kilowatts—but is beneficial for modular use.
