Sun Above the Horizon: Meteoric Rise of the Solar Industry (Jenny Stanford Series on Renewable Energy)

The meteoric rise of the photovoltaic (PV) industry is an incredible story. In 2013, Google’s investments in PV systems totaled about half a billion dollars and Warren Buffet, one of the famous investors, invested $2.5 billion in the world’s largest PV system in California. These gigantic investments by major financial players were made only 40 years after the first two terrestrial PV companies, Solarex and Solar Power Corporation, were formed in the USA. Back in 1973, the two companies employed 20 people and produced only 500 watts of PV power. Now, just 40 years later, over a million people work in the PV industry. The worldwide capacity of operating PV electric generators equals the capacity of about 25 nuclear power plants. The PV industry is growing at an annual rate of 30 percent, equivalent to about five new nuclear power plants per year. Today, solar electricity is a significant supplier of electricity needs, to the extent that PV is forcing the restructuring of 100-year-old electric power utilities. This book describes how this happened and what lies ahead for PV power generation.

Dr. Peter F. Varadi escaped from Hungary in 1956 and, after a scientific carrier in 1968, was appointed head of the Communication Satellite Corporation’s (COMSAT’s) chemistry laboratory in the US. In this function he also participated in research on photovoltaic (PV) solar cells, which were used to power satellites. In 1973 he co-founded SOLAREX Corporation in Rockville, Maryland to develop the utilization of solar cells (PV) for terrestrial applications. SOLAREX was one of two companies that pioneered this field. In 1983, it was the largest PV company in the world when it was sold to AMOCO. Varadi continued consulting for Solarex for ten years, and after that for the European Commission, The World Bank, and NREL, among other organizations. In 2004, in recognition of his lifelong service to the global PV sector and his continuing commitment to strive for excellence in the PV industry, received the European Photovoltaic Industry Association (EPIA) John Bonda prize.
