Photovoltaics (PV), the solar power, which was nothing a few years ago, is the world leader in clean and sustainable energy today. It has become low-cost and affordable for everybody: Millions of people have already invested in it. This book reports on the euphoria resulting from solar PV that started about half a century ago in the United States, followed by Japan. By the turn of the century was triggered the first PV market explosion in Germany, followed by the great financial and industrial turmoil ending up with China’s leadership. Today, the solar euphoria has embraced the whole world, with hundreds of billions of dollars being invested in millions of PV plants on buildings or on the ground. The book is a guide to investing while helping to save the environment. It tells everything about solar power.
