1 PV SYSTEMS PREPARING & EDUCATING YOURSELF: - SITE, SYSTEM, ECONOMICS & EXPECTATIONS - GOVERNMENT SUPPORT PROGRAMS

2 WELCOME & THANK YOU FOR COMING SEAN MACKINNON SENIOR ENERGY ADVISOR ENERGY SOLUTIONS CENTRE

3 Art by my 5 year-old SHOULD I START WITH A JOKE? (THAT S WHAT THEY SAY )

4 WHAT DO WE DO AT THE ESC? Government office Energy efficiency and renewable energy Incentive and other programs Public education and outreach Pilot projects & Policy

5 PV SYSTEMS - OUTLINE What? Why? Does it work here? Basic design Energy expectations & economics Moving forward Program$ (incentives, etc )

6 SOLAR. PV WHAT IS THE DIFFERENCE?

7 These are solar thermal panels (they deliver heat)

8 These are solar electric panels or Photo-voltaic (PV) panels (they deliver electricity)

9 WHAT ABOUT POWER AND ENERGY? ENERGY KILOWATT-HOURS (KWH) THE ABILITY TO DO WORK POWER KILOWATTS (KW) THE RATE OF DOING WORK

10 ANOTHER EXAMPLE OF ENERGY / POWER The grid has (basically) unlimited power Yukon has perhaps 130 megawatts (MW) of capacity You consume and pay for energy in 12 /kwh ENERGY (KWH) THE ABILITY TO DO WORK POWER (KW) THE RATE OF DOING WORK

11 WHY DO I WANT A PV SYSTEM?

12 WHY DO I WANT A PV SYSTEM? Save money / Earn money Offset emissions Energy security & back-up Heat my house Be cool / Save the world

13 DOES PV WORK HERE?

14 DOES IT WORK HERE? YES! Yukon more sunlight than some areas at same latitude Great generation from mid-february to late September Snow cover is not very significant

16 KWH/KWP 200 Percent of annual generation by month 16.0% % 14.1% 14.6% 13.6% 13.7% 11.6% 14.0% 12.0% 10.0% % 8.0% % % 5.1% 4.0% % 1.5% 2.0% 0 January February March April May June July August September October November December 0.5% 0.0%

18 LOCAL INSTALLERS Several experienced installers and electricians More all the time Lets just leave it at that

19 BASIC DESIGN BUILDING PLANNING SITE ASSESSMENT SYSTEM DESIGN

20 BUILDING ASSESSMENT New build Inspectors Structural Azimuth Tilt Roof penetrations and structures Large continuous surfaces Conduit(s) - labelled Existing Inspectors Structural Shading Orientation

22 SITE ASSESSMENT The factors from the site assessment (and the budget) will determine: Location, Orientation Capacity, etc

29 ENERGY EXPECTATIONS & ECONOMICS

30 ENERGY EXPECTATIONS Household demand Conventional Heat (electric) System generation annually Offset & export (savings & earnings)

31 1,200 Household electrical consumption vs. PV system generation 1, Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Generation (kw) Consumption (kw)

32 ECONOMICS Installed cost (capital) Savings & earnings (offset & export) Simple payback Assumptions Value of energy ROI, NPV, LCOE

33 MOVING FORWARD

34 MOVING FORWARD Talk to Building inspector Local installer &/or experienced electrician Me! Do the install Apply to Micro-generation Program...

35 MICRO-GENERATION PROGRAM

36 MICRO-GENERATION PROGRAM Facilitates Yukoners wishing to grid-tie a renewable energy system (usually PV) Grid-tied systems only Reimbur$es for energy exported (annually) 21 /kwh grid-tied & 30 /kwh off-grid Open to most residential, commercial & industrial rate classes

37 MICRO-GEN APPLICATION PACKAGE Application form Electrical diagram Site diagram Inverter spec sheet Electrical inspection Operating agreement
