  1. Renewable Energy Method: Solar Photovoltaic Final Project Iberian Partnership for Technician Excellence, Summer 2012

  2. Andrew Sink • Studying Energy Technology at SCF • Taken various courses related to Alternative Energy • Electronics Hobbyist • Very excited to be in Spain.

  3. Burton Bellamy • Has an A.S. in Engineering Technology from HCC • Interested in DIY projects, alternative energy included • Pursuing a degree in Mechanical Engineering

  4. Project Scope • We will be using what is known as a “Grid-tie” system, which allows the PV panels to interface with the electrical grid. • We are going to show some of the technology and calculations that go into building a system such as this.

  5. Off Grid Systems • Battery Banks, a good idea for everybody? 24 kWh System $3,500 Would support our house For only 1 day.

  6. An example of a Grid Tie PV system

  7. Project Scope • Site Plan • Monthly House Electrical Loads • Utility Costs • System Sizing • Panel Selection & Connection • Panel Calculations • Net Metering • Costs & ROI

  8. House Specifications • 3-bed, 2-bath, 2,000 sq. ft., located in Tampa, FL. • Single story, 5,000 gal. pool, 2 adults, 2 children. • The pitch of the roof is 25.5 degrees, the front door is facing NE. • Calculations made assuming the month of January.

  9. Household Electrical Loads • The basic needs in an average Florida home. • The kWh they consume monthly. • Energy efficient products. • Total monthly electrical load is 432.6 kWh.

  10. Household Electrical Loads

  11. Efficiency Calculations • Tilt= tilt-(41-Lat) • Lat: 28, Tilt:83 • Tilt=83-(41-28)=70 • 75% Efficiency

  12. Efficiency Calculations • Leaves us with 4140W (4.1kW) • 4.1kW x 5.6(MPH) x 31= 712kWh/m

  13. Panel Selection • Schott Poly 230 • 230 Watt output • 30 Volts, 7.66 Amps • Superb Warranty

  14. System Sizing • Total of 237.6 sq. ft. of usable space on each side of the roof. • We used 2, creating a usable area of 475.2 sq. ft. • 12 panels on each side of the roof • Orientation/Inclination • Panels are 5.57 x 3.3 ft. in size.

  15. Panel Connection • Series/Parallel Combination • 3 groups of 8 in parallel. • Each group provides 30 Volts, 61.28 Amps. • Total when placed in series is 90 Volts, 61.28 Amps

  16. Inverter Technology • Outback Inverter 6000W • Provides an all-in-one solution for power conditioning. Regulator/Conditioner/AC Inverter • 120V grid tie-in output, regulated voltage/current • Provides a small battery back-up

  17. Component Costs Total System Cost: $21,606

  18. Net Metering • A brief introduction to Net Metering • Replace 2 counters with 1 single Bi-Directional grid tie-in Meter. • Now available through all Florida Utilities

  19. Total Costs • Cost of installed system : $21,606 • Cost of energy consumed/year: $467.20 • Projected price of energy generated/year: $758.79 • Price per kWh: $0.09

  20. Rebate and Incentive Programs • Florida Renewable Energy Technologies and Energy Efficiency Act • Provides $4 a watt, maximum of $20,000 • Federal Program • Allows for 30% to be refunded as a tax credit.

  21. Return of Investment (ROI) • Formula = Investment / Yearly Income • Investment Before Rebate = $21,606 • Investment After Rebate = $1,606 • ROI = ~2 Years

  22. Conclusion • Sensible amount of electrical loads • Above 100% power generation • Simple grid tie-in system • Very low amount of maintenance • Very low Return of Investment time A very good decision!
