  3. What is Photovoltaic • Photovoltaic-Cells can produce with light electricity

  4. Components • Modules (mono or poly crystalline) • Power range from 160 up to 250 W • 6” cells => 156x156mm • Efficiency approx. :14 % • Size: 1650x990x50mm • Mechanical load: 5.400 Pascal => 550 kg/m² • Tested: STC and NOTC • Guaranty: 5 years product guaranty 10 years 90% performance guaranty 25 years 80%

  5. Components • Inverters • Power range: 1kW up to 330 kW • Most common: 3 – 10 kW (1 – 3 phases) • Mpp voltage range: 300 – 700 V • max. input voltage: up to 900 V • max. Efficiency: 95 – 98% • Mpp Tracker: 1 – 3 Tracker • Protection class: IP55 – IP65 • Interfaces: USB RS485

  6. Components • Mountingsystem • To fix the plant on • roof • ground • wall • For each requirement there is the right mountingsystem • Material: Aluminum / Stainless Steel • Certificates: • TÜV • LGA

  7. Components • Surge Protection Devices • Class (B + C) or (C) • 1000 V • especial for pv-plants • Plug and Play Surge Protection Box • DC-Switch • integrated in Inverter • separate DC-Switch Box

  8. Components • Additional equipment • Wires with special UV-Protection • 4² red/blue • 6² black • Connectors: between all components • Tyco • MC3/MC4 • Special Devices: • Software to read out the earnings • Public Displays

  9. Planning • Facts to plan a PV-Plant • Direction of the house? South • Angle of the roof? 30-35° • Where is the house? For the calculation • Which roof has the house? Mounting system • Size of the roof? Number of modules • Shadow? Earnings • Place for the inverter?

  10. Sun Radiation

  11. Roof Direction

  12. Usage of PV-Plants • Grid Connected • Bring in electricity to 100% in the public network • Use the electricity as good as possible on your own, rest goes in the network • Stand alone • Battery system (small plants) • Street lighting

  13. Strategy • Sales to existing Customers • Trainings, advice and efficient logistics • 2 PM’s central / local specialists in the agencies • Planning form the customer • Special planning by PM’s in Vienna • Customers • Electro companies • No wholesalers • Distribution program: modules, inverter mountingsystems, additional components

  14. Timetable • November/December • Selection of the components • December/January • Apply products in WWS • Design PV-catalogs • January/February • Storage filling • Infodays • February – 2011 • PV-Trainings and Presentations

  15. Application Area • Grid Connected • Single and multifamily houses 3-10 kW • Sets and single components • 3,4,5 – 10 kW Sets • Stand alone • Single and multifamily houses, Holiday huts • Sets but only on separate calculation • Only B-Article

  16. Procedural methode • Schrack Infodays • Present the poducts • Train the Trainer/Customers • Target: they calculated the pv-plant on their own • Trainers: 1 Specialist in each agency • 2 Experts in Vienna • Delivering • Sets • Single components

  17. Questions • Time for your questions, feedback an optimizing ideas!

  18. LET‘S KEEP IN TOUCH.
