However, it is estimated that up to 173,000 TW (terawatts) of solar energy can hit the Earth at any given moment. So we are still only using a tiny fraction of the energy available to us,
Global installed solar PV capacity by scenario, 2010-2030 - Chart and data by the International Energy Agency.
Global solar photovoltaic capacity has grown from around five gigawatts in 2005 to approximately 1. 6 terawatts in 2023, with installations increasing by almost 40% in that last year.

“The unprecedented roll-out of solar worldwide, and now the fact that we have made this 2TW milestone, or about 7 billion solar panels installed, is the culmination of decades of hard work,”
Estimates the energy production of grid-connected photovoltaic (PV) energy systems throughout the world. It allows homeowners, small building owners, installers and manufacturers to easily develop
PV modules typically comprise 60-72 cells arranged in a rectangular grid, laminated between transparent front and structural back surfaces. They usually have metal frames and weigh 34-62 lbs.
Electricity generation from solar, measured in terawatt-hours.
“Notably, 2 TW of solar is equivalent to the total installed electricity capacity of India, the USA and UK combined and could power an estimated one billion homes, based on a global average...
