Germany is one of the first European countries to promote the development of the photovoltaic industry. In 1990, after Germany passed the "100,000 Roofs" project, the German photovoltaic industry developed rapidly in the global market. As of today, 1/3 of the large number of photovoltaic projects installed worldwide are in Germany.

If we look back, no one could have predicted that renewable resources, especially photovoltaic energy, would grow so quickly. In the past three years, solar energy has received the largest investment in renewable energy in Germany, accounting for almost 60% of the entire new energy investment.

Currently, the global photovoltaic cost has dropped from 5 euros/watt in 2006 to 1 US dollar/watt last year, and has continued to decline. Achieving such results is inseparable from support in research and development, policies to encourage innovation, and market penetration. International photovoltaic research institutions continue to develop high-efficiency photovoltaic cells; the vigorous promotion of Germany, Italy, France, China, Japan and other countries; and the on-grid electricity price policy have played a huge role in promoting the development of the photovoltaic industry.

At present, Germany's photovoltaic power generation accounts for 5% of the total domestic power generation and will continue to develop rapidly in the next few years. Over the past decade, Germany has seen that the rapid development of the industry ultimately directly benefits end users. Installation on rooftops does not require an increased burden on consumers, accelerating the reduction of photovoltaic electricity prices in Germany.trina solar panels
