Andrew Sink • Studying Energy Technology at SCF • Taken various courses related to Alternative Energy • Electronics Hobbyist • Very excited to be in Spain. Iberian Partnership for Technician Excellence, Summer 2012
Burton Bellamy • Has an A. S. in Engineering Technology from HCC • Interested in DIY projects, alternative energy included • Pursuing a degree in Mechanical Engineering Iberian Partnership for Technician Excellence, Summer 2012
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. Iberian Partnership for Technician Excellence, Summer 2012
Off Grid Systems • Battery Banks, a good idea for everybody? 24 k. Wh System $3, 500 Would support our house For only 1 day. Iberian Partnership for Technician Excellence, Summer 2012

Project Scope • • Site Plan Monthly House Electrical Loads Utility Costs System Sizing Panel Selection & Connection Panel Calculations Net Metering Costs & ROI Iberian Partnership for Technician Excellence, Summer 2012
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. Iberian Partnership for Technician Excellence, Summer 2012
Household Electrical Loads • • The basic needs in an average Florida home. The k. Wh they consume monthly. Energy efficient products. Total monthly electrical load is 432. 6 k. Wh. Iberian Partnership for Technician Excellence, Summer 2012
Household Electrical Loads Iberian Partnership for Technician Excellence, Summer 2012
Efficiency Calculations • Tilt= tilt-(41 -Lat) • Lat: 28, Tilt: 83 • Tilt=83 -(41 -28)=70 • 75% Efficiency Iberian Partnership for Technician Excellence, Summer 2012
Efficiency Calculations • Leaves us with 4140 W (4. 1 k. W) • 4. 1 k. W x 5. 6(MPH) x 31= 712 k. Wh/m Iberian Partnership for Technician Excellence, Summer 2012
Panel Selection • Schott Poly 230 • 230 Watt output • 30 Volts, 7. 66 Amps • Superb Warranty Iberian Partnership for Technician Excellence, Summer 2012
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. Iberian Partnership for Technician Excellence, Summer 2012
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 Iberian Partnership for Technician Excellence, Summer 2012
Inverter Technology • Outback Inverter 6000 W • Provides an all-in-one solution for power conditioning. Regulator/Conditioner/AC Inverter • 120 V grid tie-in output, regulated voltage/current • Provides a small battery back-up Iberian Partnership for Technician Excellence, Summer 2012
Component Costs Schott Poly 230 @ $400 ea. (24) $9, 600 Outback Inverter 6000 W @ $9, 400 (1) $9, 400 6 AWG Wire, 500 Ft. @$326 (1) $326 Mounting Hardware @ $190 (12) $2, 280 Total System Cost: $21, 606 Iberian Partnership for Technician Excellence, Summer 2012
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 Iberian Partnership for Technician Excellence, Summer 2012
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 k. Wh: $0. 09 Iberian Partnership for Technician Excellence, Summer 2012
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. Iberian Partnership for Technician Excellence, Summer 2012
Return of Investment (ROI) • Formula = Investment / Yearly Income • Investment Before Rebate = $21, 606 • Investment After Rebate = $1, 606 • ROI = ~2 Years Iberian Partnership for Technician Excellence, Summer 2012
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! Iberian Partnership for Technician Excellence, Summer 2012
