 Here are some facts about solar energy:

Abundance

Solar energy is the most abundant energy source on Earth, with 173,000 terawatts of solar energy striking the Earth every moment. This is more than 10,000 times the world's total energy use. 

Cost

Solar energy is one of the cheapest energy sources available. In the U.S., solar energy prices have dropped significantly in the last decade and are now 33% cheaper than gas power. 

Sustainability

Solar energy is emission-free and sustainable, with a very low carbon footprint and zero pollution in electricity generation. 

Applications

Solar energy is used in many applications, including powering the International Space Station (ISS), which is entirely solar powered. 

Efficiency

Monocrystalline panels typically have higher efficiency rates, around 22%, while polycrystalline panels achieve around 15-20% efficiency. 

Homeowners

Most homeowners can break even on their system investment in under 10 years. 

History

The first silicon solar cell was built by Bell Laboratories in 1954. 

Early adopters

The space industry was an early adopter of solar technology, using it to provide power aboard spacecraft in the 1950s
