Leading the World in Solar Thermal Power

Leading the World in Solar Thermal Power

Solel Snapshot Ø Over 230 employees – world’s largest solar thermal company Ø 20 years of solar thermal experience Ø Solel team designs, manufactures and installs solar fields for utility scale power, on-site power plants and industrial solar heating & AC Ø Delivers power when it’s needed most: during peak demand hours

Leadership in Solar Thermal Energy Ø Over $100 million in solar thermal orders in 2006 Ø The only commercially proven electricityproducing solar thermal technology Ø Developing three 50 MW solar power plants in Spain with Sacyr Ø Powers nine operating solar power plants in California as well as plants under construction in Nevada and Spain Ø Solel 6 solar power plants feature 40% increase in yearly electrical output

What is Solar Thermal Power? Ø Free and secure resource, widely available and highly predictable Ø Uses reflectors to concentrate sun’s energy and create heat Ø Uniquely suited for answering peak demands Load Wind * Solar ** % of power generated vs. capacity

World Recognizing the Full Costs of Fossil Fuels Stern Review on the Economics of Climate Change, HM Treasury, Oct. 2006 Climate change is the greatest market failure the world has ever seen. Three elements of policy are required for an effective global response: 1. Carbon pricing, through tax, trading or regulation. 2. Innovation and the deployment of low-carbon technologies. 3. Remove barriers to energy efficiency: inform, educate and persuade individuals to respond to climate change. Solar thermal is a no-carbon technology and comes out least expensive on a level playing field.

Solar Thermal: Best Clean Energy Potential Vinod Khosla, co-founder of Sun Microsystems and leading venture capitalist: …. the world should focus on low-cost technologies that can be rapidly deployed on a large scale and that can quickly reduce costs with new technology developments…. . Solar thermal technology is the most promising: every piece of solar thermal technology is decreasing in cost over time…. Wind and photovoltaic technologies are less likely to solve the world’s climate-change problems.

Solel’s Range of Solutions 1. Utility Scale Central Power: Turnkey Solar Power Stations 2. Solar On-Site Power Plants (Distributed Power) 3. Solar Industrial Heating and Cooling

Solar Co-Generation: Off-the-shelf 1, 960 k. We Peak Demand Displaced Ø 1, 160 k. We Gross Power Ø 905 k. We Net Ø 880 Ton Refrigeration

3. Industrial Cooling and Heating Collectors supply hot water at 100º C, enabling operation of absorption cooling machines Industrial cooling and heating system installed in Trento, Italy

Solar Industrial Water Heating: Applications Ø Industries Ø Large residential Ø Hotels & resorts Ø Swimming pools Ø Hospitals FACT: About 50% of utility-produced electricity is used for heating and cooling

Large Scale Water Heating - Spain

Air Conditioning (Toyama Japan)

Pool Heating

Solar Air Conditioning Ø Main components of solar cooling system are: § Solar collectors generating high temp water § Single / Double stage absorption chiller § Integration into a commercial system

Solar Industrial Water Heating Ø Energy costs involved in heating water with fuel/electricity can be dramatically reduced using solar energy Ø Reduces exposure to fuel price increases Ø High solar radiation areas particularly suited for solar energy applications Ø Payback period is relatively short making the cost/benefit more attractive
