  3. Alpha Energy Designs and installs alternative energy power systems for residential, commercial, institutional, and remote applications.

  4. Solar Power SuppliesOff Grid

  5. Solar Power Supplies - SPS • PV array is only charging source • 6 to 10 days battery autonomy • Best for loads under 150W • Best with DC loads, but AC loads okay • Pole, ground, wall, and trailer mounts • Uncontrolled battery environment • Can include battery charger for use with portable generator

  6. Solar Power Supplies - SPS • Optional Features: • Inverter for powering AC loads • AC battery charger, which can be connected to a portable generator • Maximum power tracking to get most out of PV array • Low voltage disconnect to protect batteries • Low voltage and high voltage alarms • Remote control & monitoring

  7. SPS Case Study • Customer: Greenstar Engineering • Application: Remote SCADA • Location: New York State • Load: Waste site monitoring, 25W, 12V • Solution: SPS12-246/324G (12VDC, 246W PV, 324Ah battery) • (2) Sharp 123W, 12 VDC PV modules • (1) Morningstar charge/load controller • (3) East Penn 108Ah solar gel batteries • (1) PRC1000 programmable relay controller • Programmable relay allows scheduled load control • Approximate Cost: $2,300 • Customer Feedback: “Working Great!”

  8. Hybrid Power Supplies

  9. Hybrid Power Supplies - HPS • Designed for applications with larger electric loads or requiring greater reliability in areas with highly variable solar resources. • Incorporate an auxiliary engine generator sized to provide 25% to 75% of the load energy, with the balance supplied by the solar array. • The generator operates at full load providing optimum energy delivery, and higher system fuel and maintenance efficiency.

  10. Hybrid Power Supplies - HPS • PV array and generator charge batteries • 4 to 7 days battery autonomy • Best for loads larger than 200W • Best with DC loads, but AC loads okay • Skid and trailer mounted systems pre-integrated • Semi-controlled battery environment • For larger loads, heavy-duty or two alternating generators recommended • Wind turbines can be added as charging source

  11. HPS Case StudyAlamosa PCS (Sprint) • Alpha HPS 24-900/1500/6 • 4 to 7 days battery autonomy • 900W PV Array • 1500 Ah MTI battery bank • 6 kW AlphaGen DC generator • Skid Mounted • Installed in one day! • Annual recurring cost savings (fuel and maintenance) ~$20,000 / yr • Including Capital Cost:Pay Back in 1-2 years

  12. Combination Sun + Wind

  13. Offgrid-Solutions

  14. Off Grid Example:Bell Mobility in Canada

  15. The unique location…

  16. Challenges and Opportunities Challenges for Bell Mobility Remote location Off grid ~ no commercial AC present Very high wind strength area Helicopter access only; located 700metres above sea level on Anvil Island Lack of experience Opportunity for Alpha Our strengths proved valuable Network experience and customer history Proven relationship and experience in their backyard

  17. What was required… Hybrid Power System incorporating: DC System Cordex Controller Solar Charge Controller 2.6kW PV Array AlphaGen 5kW DC generator with external propane tanks to supply up to 3 days… DC distribution

  18. During Construction…

  19. PV Array

  20. Grid Tied

  21. Commercial & Institutional

  22. Grid-Tied Solution Planning

  23. Solar Panels / Photovoltaic Panels • Alpha Panels have mono crystallin cells inside • Others use • poly crystallin cells (less efficiency but cheaper) • Thin layer (a-Si, amorphus Silicon, CIS, CdTe) • Concentrators III-V (future, tracker needed)

  24. Solar Tubes

  25. Solar Foil

  26. Technical Details • Amorphous Silicon Solar Cells • UV stable teflon foil • Glued to metal sheet or foil • Special developed glue for long lasting connections • CE and SKII approved • 92W per unit • High voltage – one unit can feed one PV inverter

  27. Applications • Roofs that cannot support the weight of crystalline modules • Roofs not oriented to the south – complete roof can be covered • Large roofs where efficiency is not the point • Curved surfaces

  28. Inverter: e.g. SMA 3800

  29. Inverter: Connecting to Grid

  30. Communication: TCP/IP, RS-485

  31. Display

  32. Stands, Frames

  33. Trackers, Movers

  34. Wind Generators

  35. Rutland 503 Wind Turbine 12V version available

  36. Rutland 913 Wind Turbine 12V and 24V version available

  37. SMA AeroSmart 5KW Wind Turbine • 5KW maximum power • With WindyBoy Windcharger • With 12m or 18m tower

  38. Example of wind turbine Integration
