Solar Statistics

Solar is now scaling at a pace that turns capacity headlines into cost and climate outcomes, with global solar capacity forecast to triple to 4.7 TW by 2030 and investment reaching $500 billion in 2023. At the same time, rooftop and off grid growth run in parallel from Australia’s 1 in 3 homes to more than 1 billion people relying on off grid solar, so you can see how affordability, policy, and hardware efficiencies are reshaping adoption worldwide.
