  1. By Ken Clifton Topics: Solar Photo Voltaic Micro Inverters Solar Thermal Biomass Renewable Energy Implementations Visit http://www.kenclifton.comthen click Renewable Energy

  2. Overview • Why? • Why Not PV? • PV the Only Way I Was Interested... • My Process • Sealed Air Leaks, Improved Insulation, Radiant Barrier LED Bulbs, High-Efficiency Heat Pump • Biomass • Solar Thermal • Solar Photo-Voltaic

  3. Why? • Sealed Air Leaks • Added Insulation • Converted to LED Lighting • Compared Power Bills Same Month,Previous Year, with Current Year... • Used 100 kWH less, but guess what?

  4. Why (cont.)? • 2010 Electric Bill was still more, Even though used 100 kWH less !!! • In 2010 Duke added many new ridersAND upped the rate... • Conclusion: If you can't beat them,– JOIN THEM !

  5. Feb 2011 Power Bill

  6. Feb 2011 Power Bill

  7. Your First Generation Should Always Be: .... • Solar thermal • The most bang for the buck! • 65 Percent Tax Credit (not deduction!)FULL 65 PERCENT OF COST BACK • New technologies... • I went with evacuated tubes for themost performance in the winter.

  8. Your First Generation Should Always Be: Solar Thermal

  9. Your First Generation Should Always Be: Solar Thermal

  10. Your First Generation Should Always Be: Solar Thermal

  11. Why NOT PV?(I would not do this because...)

  12. Why NOT PV?(I would not do this because...) • Solar Panels in Series (like XMAS lights) • Shading Issues • Manufacturing tolerance differences • Sunrise/ Sunset • DANGEROUS!!! (high DC voltage)? How can you work on this in the daylight...? What about troubleshooting a prob w/ 24 panels • Big Expensive Wire • Cost to Expand System • Average Service Life of String Inverters(10 years the norm)

  13. PV the Only Way I Was Interested...

  14. PV the Only Way I Was Interested...

  15. PV the Only Way I Was Interested... • Wall Street Journal TechnicalExcellence award: Enphase Energy • Parallel system (invert at each panel and wire in parallel) • No single point of failure AND 119 year MTBF • Every inverter runs flat-out! (no manufacturing tolerance issues) • Shading affects 1 module only (not whole string) • Sun rise/sunset performance much better • Small AC wire, less dangerous voltage • Easy to troubleshoot – look at the browser!! • Can work on wiring in the day • Cost to expand system is much less!

  16. PV the Only Way I Was Interested...

  17. PV the Only Way I Was Interested...

  18. My Process... • Caulk is $2 tube versus $800 per panel w/ inverter, insulate, radiant barrier, LED lighting • Biomass for heat (might go evac tubes now) • PV: NC Utilities Commission Rpt of Proposed Construction • Duke Interconnection Application • Approval to construct • NCUC: Rpt of Construction • Building Permits • Construct • Duke Permission to Energize • Went through the whole process TWICE! • 1st time completed Nov of 2010 • Watched 1st Array run, worked so well did same thing again! • 2nd time completed Jan 2011

  19. My Process (cont.)

  20. My Process (cont.) 100,000 BTU Forced-Air with 14 day fuel supply in hopper
