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.

Energy Storage

Energy Storage allows solar system owners to save the energy generated by their solar panels in a battery.
