  1. Development and Deployment Trends in Solar and Portable Power: An Industrial Perspective Heath Naquin The University of Texas at Austin 07/11/2014
  2. Welcome
  3. Agenda • Overview of US and International Solar Markets • Core Solar Technologies on the Market • Peripherals • Efficiency vs. Cost (Industrial vs. Academic Perspective) • Portable Power Implications • Question and Answers
  4. Who is the Talking Head? • Heath Naquin, MSTC, BBA, PMP • Managing Director UT Austin NSF Center for Next Generation Photovoltaics • Extensive government work • Technology Transfer and Commercialization experience in 22 Countries
  5. Public View of Solar Technologies • Easy Clean Energy • Very Green Technology • Super Cost Effective to Deploy • Good for Going off the Grid
  6. Industry View of Solar • Marketing Platform • Pain mandated by Government • Money Pit • Unproven Technology
  7. Military View of Solar • Energy Independence enabling mission readiness 24/7 • Remote Operating Base Enabler • Cost Savings Mechanism • Others???
  8. My View of Solar
  9. Solar Adoption Curve US • 13,000 MW of installed PV/Solar capacity in the US as of 2014. • More than 445,000 PV systems in operations in the US today. • Average Cost per Watt (Installed) $2.59/W (at Utility Scale • Utility Scale Power Installations lead the Charge
  10. Examples from the Field • Agua Caliente Solar Project – First Solar in Arizona ($2.10/Watt) – 250MW (AC) – 5,200,000 modules – Power for nearly 100,000 homes – 2,400 acres for site
  11. Trends in Solar Adoption US
  12. Solar Adoption in the US Military • Part of 2025 Goal of Military to have 25% of energy used be from renewable sources (3 GW) • 130 MW currently installed at Military Bases • PV slated to account for 58% of the 1.9 GW of renewable energy to be installed by 2017 • Deployed in a variety of instances in MENA and Pacific Theater
  13. Fort Huachaca: Army • 18-megawatt solar installation planned at Fort Huachuca in Arizona • Headquarters: U.S. Army Intelligence Center and the U.S. Army Network Enterprise Technology Command (NETCOM)/9th Army Signal Command • Largest in US Military History • 68 acres for the site • Installation will deliver ¼ of base electricity needs
  14. Davis-Monthan Air Force Base. • 57,000 solar panels • 170 acres • 16.4 MW—enough to power 3,000 homes • 35 percent of base energy needs met with solar power • $500,000 in annual energy savings
  15. Navy Specific Solar Examples • Space and Naval Warfare Systems Command (SPAWAR) complex San Diego: 1.3 Megawatts • Norfolk Naval Station: 8600 panels, 2.1 MW of production (only 2% of energy needs)
  16. Keys to Military Solar Installations • Public Private Partnership with many players • Military usually provides land for solar installs for “free” • Incentives and long term generation estimates cover financing from third parties • Military usually retains priority in “emergency situations for production” • Consistent with with typical fossil fuel arrangements • Incentives still drive total cost for installs
  17. How Big of a Market? • Global Market for PV in total is estimated at $38 Billion annually. • Estimated to grow to roughly $47 Billion by 2017 • Largest areas will be portable power solutions and consumer gadgets powered by solar.
  18. Energy Mix for Solar US
  19. Country Comparison
  20. Types of Solar Energy/Technology • Photovoltaic Systems – Producing electricity directly from sunlight. • Solar Hot Water – Heating water with solar energy. • Solar Electricity – Using the sun's heat to produce electricity. • Passive Solar Heating and Daylighting – Using solar energy to heat and light buildings. • Solar Process Space Heating and Cooling – Industrial and commercial uses of the sun's heat.
  21. The Gold Standard?
  22. Types of PV Panels • Crystalline Silicon (c-Si) – 95% of all panels are typical Crystalline Silicon – Mono (expensive) Poly (cheaper) – Average Efficiency about 15% • Thin-Film Solar Cells (TFSC) – Amorphous silicon (a-Si) – Cadmium telluride (CdTe) – Copper indium gallium selenide (CIS/CIGS)
  23. New Solar Technology Trends
  24. Lets talk about efficiency… • Big Confusion on this… • Solar efficiency refers to the amount of ambient light that can be converted into usable electricity • Academics love talking about efficiency – Sunpower best with about 26% efficiency – Thin Film record of around 17% – Theoretical Max of around 44%
  25. Computation of Efficiency • Efficiency is defined as the ratio of energy output from the solar cell to input energy from the sun. • This is calculated by dividing a cell's power output (in watts) at its maximum power point (Pm) by the input light (E, in W/m2) and the surface area of the solar cell (Ac in m2).
  26. Efficiency in Practice • Solar Panel with 20% Calculated Efficiency and area of 1m2 • Under test condition, AKA “simulated high noon” will product 200W • In Colorado (higher sun exposure and quality of sunlight) system will produce 440kWh/year • In Michigan (lower sun exposure and quality) same system will produce 280 kWh/year
  27. In reality… • Efficiency less important matter, rather cost per watt of production. • Energy is a commodity • Consider – Nat Gas costs about $.06/W – Solar, needs to achieve sub $1/Watt installed to be competitive over 25 years to fossil fuel.
  28. Lets talk about Balance of Systems • Balance of Systems (BOS) costs refer to the total cost to deploy a solar solution – Best in US in Austin at $3/W installed – Worst is NYC at $7/W installed
  29. Illustration of BOS
  30. Solar Peripherals to be Aware of • Micro Invertor/Convertor • Concentrators • Trackers • Rackers • Scrubbers • Etc…
  31. Typical Issues with Solar • Lifecycle of Use • Efficiency Degradation • Upkeep and maintenance costs • Land Costs • Storage, Storage, Storage…
  32. Business Case for Solar
  33. Calculating Benefit of Solar • Consider the following – Efficiency of Panel – Cost to Purchase – Cost to Install – Estimated Production over 25 years – Estimated Cost to Maintain over 25 years – Average Amount of SunLight per position
  34. Portable Power
  35. Enabling Technology for Portable Power • Thin Film and Amorphous Silicon Lead the way • Alternative Substances • Cost, Weight, Flexibility and durability more important than Efficiency • ITAR is a big issue
