17. Macroeconomic & Industry Review CONCENTRATING SOLAR POWER • Concentrating solar power (CSP) is a technology that uses mirrors to focus sunlight on a particular surface to create electricity • CSP has higher energy efficiency than Photovoltaic • Large-scale deployment of this technology is anticipated during the next five years A parabolic trough CSP

18. Macroeconomic & Industry Review SOLAR POWER INDUSTRY • Beyond 2012, government legislation is uncertain, depends on new congress • Housing crisis and tough economic conditions cause reduction in electricity power.

19. Macroeconomic & Industry Review PHOTOVOLTAIC SOLAR PANEL • The solar panel can be used as a component of a larger photovoltaic system • Most solar modules are currently produced from either monocryatalline or multicrystalline • The high cost solar photovoltaics and its weather dependency have restricted its use in the United States A photovoltaic solar panel

20. Macroeconomic & Industry Review SOLAR MATERIAL INDUSTRY • Industry : 34.8% from 2006-2011 • Falling silicon prices (a vast oversupply during recession), growth in demand and government incentives are major factors for high growth • The RPS (Renewable portfolio standards) stipulate certain States must generate a percentage of their total energy from renewable energy Source:http://clients.ibisworld.com/industryus/default.aspx?indid=754

21. Macroeconomic & Industry Review SOLAR MATERIAL INDUSTRY • Higher steaming coal price will have positive affect on solar panel demand. • Heavy price competition among global players • Increased R&D costs will weigh on profit as US firms try to compete with low-cost producers
