Welcome to the Global Market Outlook for Solar Power 2022-2026. Solar has just reached a new dimension. At the launch of this edition during the Intersolar Europe 2022 trade show in early May, total global installed solar capacity has just passed the 1 TW threshold. That’s amazing, considering that only 20 years ago, in early 2002, the cumulative grid-connected volume had reached 2 GW; today, it’s 500 times that much. And while it took 16 years, until 2018, to reach the 500 GW level, here we are, a little more than 3 years later, looking at an amount that has doubled to 1,000 GW or 1 TW. After achieving 1 TW of global solar early in the year, the forecast for the rest of 2022 is similarly bright, with the world on track to install more than 200 GW in one year for the first time. With 228 GW of expected solar installations, additional capacity in 2022 will be equivalent to total global solar capacity in 2015.
