Solar electricity is a renewable energy source that is produced by converting sunlight into usable power. This conversion occurs either through thermal energy capture or by using photovoltaic (PV) technology in panels and glass. The resulting electricity is then integrated into power grids for distribution to homes, businesses, and industries. The core technologies include photovoltaic (PV) systems, which use diverse solar module types like monocrystalline and polycrystalline, and concentrated solar power (CSP). In 2023, the global solar power market was valued at $253.69 billion, with North America commanding a 41.30% share, as reported by Fortune Business Insights. This market is set to expand to $436.36 billion by 2032, growing at a 6% CAGR. The US is a key driver of this growth, with its market expected to reach $103.96 billion by 2032. Government incentives and the push for renewable energy support this.

The COVID-19 pandemic particularly presented a complex landscape for the global solar power industry. Initially, lockdowns and economic uncertainty caused a sharp decline in activity. In the US, for example, solar permit issuances plummeted by 32% in late March 2020 compared to early February, according to the Solar Energy Industries Association. However, the pandemic also accelerated the long-term trend towards renewable energy. Economic recovery and stimulus programs prioritized clean energy, which led to a surge in demand that exceeded pre-pandemic levels. The pandemic also exposed vulnerabilities in the supply chain. With ~70% of the world’s solar panels manufactured in China and an additional 10-15% produced by Chinese companies in Southeast Asia, the disruptions in Chinese manufacturing facilities during February 2020 significantly impacted global supply.

Currently, the solar power market is experiencing growth driven by technological advancements and supportive government policies. AI, the IoT, and big data are being integrated to enhance solar efficiency, which enables better forecasting and asset management. Notably, the US Department of Energy invested $750,000 in AI diagnostics for solar systems in 2021 and allocated $7.3 million in 2020 for AI-powered solar solutions. Global efforts to combat climate change are also leading to increased investments in the solar industry. The US plans to invest nearly $1 trillion in clean energy, including $5 billion in solar manufacturing, which will create 47 new manufacturing plants and power an additional 7 million homes. The US anticipates renewable energy will account for 26% of its energy share. Renewables account for ~29% of global electricity generation. By the end of 2021, the global installed capacity of solar PV reached 842.14 GW, making it the second-largest renewable electricity source after wind. To meet the Paris Agreement targets, the International Renewable Energy Agency and the International Energy Agency aim to achieve a 90% share of renewable electricity globally by 2030.
