Photo = Light Voltaic = Electricity A PV cell converts Light (Photons) into Electricity (Volts) Solar PV System Solar Hot Water System Azimuth & Tilt . Optimal orientation is usually true South and tilt angle equal to latitude, or about 62 ̊ (in our locaon) . Local climate, shading or load characteristics can change the “ideal” orientation . Variation in collector azimuth @ 0 ̊ azimuth . +/‐ 45 ̊ = 90% solar potential . +/‐ 90 ̊= 67% solar potential . Variation in collector tilt @ tilt = latitude . Vertical ‐ 90 ̊ = 88 % . 4/12 Pitch ‐ 18 ̊ = 87% Site Considerations • Orientation has moderate effect on solar collection • Shading is the most important factor to avoid in locating a solar collection system • Better to have sun at a poor angle than no sun at all! Solar Mounting • Roof Mount – Flush • Roof Mount –Raised • Roof Mount – Flat Roof Ballasted Solar Mounting • Ground Mount – Fixed or Seasonally Adjusted • Ground Mount –Trackers (Single or Dual Axis Tracking) Some NWT Solar Installs Residential Grid‐Connected in Yellowknife Some NWT Solar Installs First Grid‐Connected System in the NWT Sir John Franklin Highschool –‐ 2 kW installed in 2003 Some NWT Solar Installs Greenstone Building – 33.5 kW installed in 2004 Some NWT Solar Installs Greenstone Building –Solar Hot Water Some NWT Solar Installs Fort Providence Seniors Residence – August, 2008 Solar Hot Water Some NWT Solar Installs Tli Cho Construction –5 kW installed September, 2011 Some NWT Solar Installs Tli Cho Construction –30 MWh generated so far !

Some NWT Solar Installs Yellowknife –various residential net‐metered systems in 2011; Pictured below is a 19 panel (5 kW) system installed in June Some NWT Solar Installs Yellowknife Residence – 661 kWh in June, 2015 So What is a Good Location? • A “reasonable” annual solar resource • Orientation towards “Solar South” preferred – SE through SW also OK depending on tilt angle • Roof mount –flush mount or elevated? – Wind & snow loads, ease of cleaning & service • Ground mount –fixed or tracking? – Available space, ease of cleaning & service • Exposure ‐ shading • Type of system: off‐grid, on‐grid –with/without batteries • Based on the above –string or micro inverters? • Offset cost of power – personal use & excess to grid Solar Pathfinder Shade Analysis Magnetic Declination Magnetic Declination The angular difference between true and magnetic south. The main cause for this discrepancy is the Earth’s non‐uniform, conductive, fluid outer core that consists mainly of iron and nickel. This layer pulls your compass needle away from true north/south. Depending upon your location on the planet, the “pull” varies in strength and direction.
