FAQS about Photovoltaic panel power generation growth

What is the growth rate of photovoltaics?

Between 1992 and 2023, the worldwide usage of photovoltaics (PV) increased exponentially. During this period, it evolved from a niche market of small-scale applications to a mainstream electricity source. From 2016-2022 it has seen an annual capacity and production growth rate of around 26%- doubling approximately every three years.

Is solar photovoltaic the new cornerstone of the global power sector?

In the past three months, the International Energy Agency, the International Renewable Energy Agency, and BloombergNEF published preliminary data for the power sector in 2024. These data hammer the same powerful message: solar photovoltaic (PV) has become the new cornerstone of the global power sector.
