1. 1 SOLAR POWER GENERATION MOUNTING SELECTION AND SPACING Jonathan Carr Power Generation Team November 16, 2016

2. 2 Solar Path at Albert Island Due to the high latitude in Ottawa, the sun only reaches a maximum elevation of 21.5º above the horizon during the winter solstice

3. 3 Choosing Mounting Panel

4. 4 Economical Choice for Mounts Radiation Sum (kWh/m2) Percent Radiation Above Fixed (%) Mount Cost Per W ($) Percent Cost Above Fixed (%) Fixed Yearly 5200.170 Fixed Adjustable 5540.170 1-Axis Yearly 63200.2547 1-Axis Adjustable 64230.2547 2-Axis 70330.53212 Note: Fixed adjustable would be set to optimal tilts of 25º in the summer (April- September) and 60º in the winter (October-March)
