Why Invest in Solar?

  • King of Electricity" – The International Energy Agency (IEA) called solar the new "King of Electricity" in its flagship World Energy Outlook Report. Solar spending will be a massive $4.2 trillion through 2050, with solar representing 35% of all new global electricity generation installs, according to Bloomberg New Energy Finance (BNEF).
  • Cheapest electricity solution – Solar is now the cheapest source of new utility-scale electricity capacity in the U.S., according to the investment bank Lazard, beating coal, natural gas, and nuclear due to the 85% plunge in solar costs since 2010.
  • Safety, Security, and Independence - “Whenever there’s a huge spill of solar energy, it’s just called a nice day.” Solar means no nuclear leaks; no nuclear waste; no fossil fuel pollution in the air, water or ground; no being held hostage by hostile oil countries; no oil wars. Just a clean, cheap, and limitless source of electricity located within our borders.
  • Tailwind from government policy support – Solar has a strong tailwind from government policy support across the globe, adding to solar's attractive economics, even though solar no longer needs any subsidies or mandates to compete.
  • Zero-carbon energy solution – Solar is a key solution for the world's zero-carbon energy needs with free fuel (sunlight) and zero CO2/pollution emissions, and flexibility to provide electricity directly to utilities and businesses/homeowners.
  • Robust 24/7 solution with solar-plus-storage – Delivering 24/7 electricity, solar-plus-battery-storage systems are already cost-effective and will become even more so as battery costs plunge by another 52% through 2030 (BNEF).
