Direct sales of energy storage photovoltaic panels

Global solar PV manufacturing capacity has increasingly moved from Europe, Japan and the United States to China over the last decade. China has invested over USD 50 billion in new PV supply capacity – ten times more than Europe − and created more than 300 000 manufacturing jobs across the solar PV value chain since 2011.

This payback period compares with the average solar panel lifetime of around 25-30 years. Electricity provides 80% of the total energy used in solar PV manufacturing, with the majority consumed by production of polysilicon, ingots and wafers because they require heat at high and precise temperatures.

Low-cost electricity is key for the competitiveness of the main pillars of the solar PV supply chain. The diversification of highly concentrated polysilicon, ingot and wafer manufacturing would provide security-of-supply benefits. Electricity accounts for over 40% of production costs for polysilicon and nearly 20% for ingots and wafers.

Since 2011, the number of antidumping, countervailing and import duties levied against parts of the solar PV supply chain has increased from just 1 import tax to 16 duties and import taxes, with 8 additional policies under consideration. Altogether, these measures cover 15% of global demand outside of China.

This indicates sustained interest in new products and technologies, although the number of product announcements, particularly for PV modules, appears significantly lower than in past editions.

China is the most cost-competitive location to manufacture all components of the solar PV supply chain. Costs in China are 10% lower than in India, 20% lower than in the United States, and 35% lower than in Europe. Large variations in energy, labour, investment and overhead costs explain these differences.
