Photovoltaic Solar in the World

Global installed photovoltaic (PV) solar capacity reached the 500-gigawatt mark in 2018, representing an increase of 25% from 2017. This growth in capacity is reflected in the power generation mix: solar supplied 2.2% of world electricity production in 2018, compared with 1.8% in 2017. The dramatic increase in solar installations was led by China, which added nearly 50% of total new capacity despite a reduction in investments. Growth was also driven by the United States and China. Europe enjoyed a strong pickup in 2018, after experiencing a marked decline from 2016 to 2017. New deployments totaled 7.6 gigawatts, bringing overall capacity in Europe to 115 gigawatts. Germany led the pack (nearly 3 gigawatts of new capacity, primarily from rooftop installations), followed by the Netherlands (1.4 gigawatts) and France (1 gigawatt). Some European countries saw a decline in power production. Output from solar PV is affected by various factors, particularly solar irradiance, which varies from year to year. Solar panel efficiency is also affected by temperature increases.
