  • 1. Small Scale Solar Energy Nov 30, 2011
  • 2. SkyFire Energy Inc• Alberta based energy company with 7 employees in Calgary and 3 in Toronto.• Greater proven energy reserves than all the fossil fuel companies in Alberta combined.
  • 3. SkyFire Energy Inc• We have been installing for over 10 years in Western Canada• CanSIA certified solar thermal installers on staff• CanSIA/Seneca College Photovoltaic Technicians on staff• Hundreds of installs across Canada• Sizes of systems have been increasing
  • 4.

  • 8. What is driving the growth?Alberta Micro Connect policy• All wire owners must allow grid tie PV systems• Retail rate compensation for export• Retail rate is going up • Moving 30 day average: $0.159 Sept 16, 2011 • CCS will double or triple the cost of electricity in Alberta at the $200-$300 per ton prediction• Albertan’s have money to invest• Medicine Hat • Hat Smart $1000 grant for PV systems• Edmonton • Looking at a FIT program• Enmax • Solar rental program for EasyMax customers
  • 9. What is driving the growth?Retail prices of photovoltaic systems are dropping2001 600 watt array $12,000 $20/ watt2005 1952 watt array $20,000 $10/watt2011 2000 Watt array $10,500 $5/watt
  • 10. What is holding Alberta Back?• No incentive programs• Lack of public awareness• Provincial government favors other solutions to carbon issues• Up front cost of PV and ST system• Low cost of energy: both gas and electricity
  • 11. Grid ParityWe are near grid parity:4000 watts x $5.00 per watt $20,000-------------------------------------------- = ------------ = $0.129/kWhr4 kw x 1292 kWhr/kw/yr x 30 yrs 155,040 kWhrCurrent retail rates are $0.07- $0.12 plus T&D in AlbertaExpect a doubling or tripling of retail rates with CCS at $200-$300/tonne
  • 12. Active Solar Energy• Electricity • Photovoltaic Modules (aka panels) • Water Heating • Solar Thermal Collectors
  • 13. SOLAR PATHFINDER PLOTDetermines Solar Resource
  • 14. Downtown Energy Center Solar Array South
  • 15. Basic grid-tied system
  • 16. • One inverter per module instead of one inverter per array of modules• Advantages – Maximum Power Point Tracking (MPPT) per module maximizes output of system and limits effects of shading – Cost is less for smaller systems – Monitoring system – Allows for modular systems - Start small and add later! – 15 year warranty (Standard for string inverters is 10)• Disadvantages – Higher cost for larger systems – Demand is high – Newer product; not as proven
