  9. 9. Solar Energy: Strength & Weaknesses Solars Main Strength ---- No Fuel Cost Solars Main Problem ---- Low Capacity Factor High Capital Cost ---- Transitional Present Cost ---- 25 cents/KWH (Twice High) Solar Cost Goal ---- Under 10 cents/Kwh (2020)
  10. 10. Solar PV Module Pricing
  11. 11. Cost of PV Solar Electricity
  12. 12. Solar Insolation and PV output • A sunny location (like Los Angeles, California, US) receives an average of 5.5 hours of sunlight per day each year. • A cloudy location (like Hamburg, Germany) receives 2.5 hours per day of sunlight each year. • A 1 kilowatt peak solar system generates around 1,600 kilowatt hours per year in a sunny climate and about 750 kilowatt hours per year in a cloudy climate.
