Solel Snapshot

• Over 230 employees worlds largest solar
  thermal company
• 20 years of solar thermal experience
• Solel team designs, manufactures and installs
  solar fields for utility scale power, on-site
  power plants and industrial solar heating AC
• Delivers power when its needed most during peak
  demand hours

3
Leadership in Solar Thermal Energy

• Over 100 million in solar thermal orders in 2006
• The only commercially proven electricity-producing
  solar thermal technology
• Developing three 50MW solar power plants in Spain
  with Sacyr
• Powers nine operating solar power plants in
  California as well as plants under construction
  in Nevada and Spain
• Solel 6 solar power plants feature 40 increase
  in yearly electrical output

What is Solar Thermal Power?

• Free and secure resource, widely available and
  highly predictable
• Uses reflectors to concentrate suns energy and
  create heat
• Uniquely suited for answering peak demands

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
• Carbon pricing, through tax, trading or
  regulation.
• Innovation and the deployment of low-carbon
  technologies.
• 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 worlds
  climate-change problems.

Solar Industrial Water HeatingApplications

• Industries
• Large residential
• Hotels resorts
• Swimming pools
• Hospitals

FACT About 50 of utility-produced electricity
is used for heating and cooling

Solar Air Conditioning

• Main components of solar cooling system are
• Solar collectors generating high temp water
• Single / Double stage absorption chiller
• Integration into a commercial system

28
Solar Industrial Water Heating

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