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

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 riders AND upped the rate... Conclusion: If you can't beat them, – JOIN THEM !

5. 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 the most performance in the winter.

8. Your First Generation Should Always Be: Solar Thermal

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

12. 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...

15. Wall Street Journal Technical Excellence 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...

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! 1 st time completed Nov of 2010 Watched 1 st Array run, worked so well did same thing again! 2 nd time completed Jan 2011

19. My Process (cont.)

20. 100,000 BTU Forced-Air with 14 day fuel supply in hopper
