The Solar Enterprise
■ Solar business has witnessed exponential growth in the last two decades both on a global scale and national scale.
■ Currently 5% of U.S electricity demand is supplied by solar power (77.7GW) Solar Energy Commercialization Discussion Paper.

Solar power -Pros
■ Renewable input power – solar power is a non-depleting source. ■ Direct conversion of forms of energy – optical energy to electrical energy. ■ Clean energy – carbon footprint eliminated. ■ Abundance of raw material for cell construction – silicon, which is a primary element in the solar cell construction is abundantly available on earth’s crust. ■ Reliable and durable technology – solar cells are robust and longlasting.

Solar power -Cons
■ Energy source intermittent – solar power is unavailable throughout the day. ■ Fluctuating output – power grid instability due to shadows and clouds. ■ Low power density – carbon footprint eliminated. ■ low power density– 80% of incident sunlight is unused. ■ power curve does not match the system demand profile – with higher penetration, its marginal value shrinks to zero. ■ Supply-demand curve mismatch – power curve does not match the system demand profile.

Growth of solar power -Favorable factors
• Technological Factors • Silicon solar cells and modules • Inexhaustible input power at zero cost • Societal Factors • Concerns about fossil fuel and nuclear power plants • An increasing awareness of sustainability issues • Economic Factors • Steady reduction in cost of PV systems • Favorable government policies and business climate
17
Factors impeding Growth of solar power PV system components • Dependence on materials that are not earth-abundant • High labor costs New PV system components • Problems with smart components Certain economic and business factors • Hostile interactions with utilities, utility regulating bodies – Net metering issues, Power demand charges • Expansion of low-cost natural gas supply and use in utility scale electricity generation • Tariffs • Recent analysis showing that solar energy suffers from a “merit order effect” which will shrink its value with increasing penetration into the energy market

Human Development Index. Solar Energy Commercialization Discussion Paper.

The United Nations Human Development Index (HDI) relates energy use to the quality of life to which most humans aspire. The middle class averages about 0.8 on the HDI and requires access to over 3,000 kWhrs per person per year. 80% of the world’s population of over 7 billion people is below 0.8 on the HDI.

Human Development Index
• The Human Development Index could be used to establish an estimate of the energy needs for the future • Assumptions: o In the near future, the population of the planet will exceed 8 billion o Let us assume we want the HDI for each nation to be 0.90 o From the chart on the previous slide, we would require access to 4MWh of electrical energy/per person (per year) o Therefore, the annual electricity requirement is  Eglobal,annual =  8E09 people ( ) ⋅  4MWh/person ( ) = 32,000 TWh (or 32 PWh)
Human Development Index Continued
• Current annual electricity generation is approximately 24 PWh, and roughly 23% is produced by renewable sources
• With a global effort to carry out more energy efficiency measures and more deployment of renewable energy, the 32 PWh target could be achieved in a 10-15 year time frame. However, the population will be much closer to 10 billion by then.
