  1. 1. Solar Electric Generating Systems forCommercial Properties<br />Ian Diamond<br />Solar Power Consultant<br />RenergyCo, LLC<br />©Copyright 2010, Ian Diamond (914) 419-3134. Please contact author for permission to reproduce in part or full.<br />
  2. 2. August 14th, 2003<br />Northeast Blackout of 2003<br />8 States + Southeastern Canada<br />50 Million people lost power<br />Cause Factors: Grid Faults and Grid Overload<br />
  3. 3. Meeting Future Electricity Load<br />Load Growth expected of 1.05% annually to 2030<br />Increase electricity generation<br />Power Plants<br />Clean Coal<br />Nuclear<br />Renewable Energy<br />Wind<br />Solar<br />
  4. 4. What is Solar Energy?<br />Solar Electric Generating System<br />aka: Solar Power <br />aka: Solar PV<br />Photo-Voltaic<br />Producing electricity from light<br />Solar Thermal <br />E.g.: Solar Hot Water<br />Utilizing energy from heat<br />
  5. 5. Why Solar Power?<br />Increasing Energy/Electricity Demands<br />Unlimited Resource. cf: fossil fuels<br />Distributed Generation. cf: Transmission costs and infrastructure<br />Maximum production during peak demand<br />Helps Utility Energy Management<br />Clean. cf: Gas, Clean Coal, Nuclear<br />NIMBY or YOYR (Yes, On Your Roof)<br />Eventual Unsubsidized Grid Parity<br />

  14. 14. Rooftop Preferences<br />Facing true south (+/- 60°)<br />Pitch: 0°- 45° (Optimum Production: 35°)<br />No obstructions<br />Off roof:<br />no trees, taller buildings, higher walls<br />On-roof:<br />Parapet walls, bulkheads, HVAC equipment, vents<br />Roof Life: 15+ years<br />No structural load issues<br />
  15. 15. Typical System<br />Crystalline Panels<br />Roof mounted / Ground mount<br />Grid-tied (no batteries)<br />Fixed mounting (no rotation)<br />Net Metered<br />Distributed Generation (On-site)<br />
  16. 16. System Sizing<br />Flush Roof Mount<br />Example: single-family residential pitched roofsouth facing, unobstructed, 500sf <br />12W-13W / square foot <br />= 6kW Solar PV system<br />Tilt Roof Mount<br />Example: commercial or multi-family flat roofunobstructed, 6000sf<br />8W-10W / square foot<br />= 48kW Solar PV system<br />
  17. 17.
  18. 18. Production Value<br />1kW Solar PV produces approximately1200 kWh per year<br />5kW = 6,000 kWh/year<br />50kW = 60,000 kWh/year<br />Avoided Electricity Cost<br />Con Edison @ $0.18 - $0.24/kWh <br />Escalating electricity costs > 5% annually<br />System Life: 30+ years<br />
  19. 19. System Cost<br />Variables<br />System Size<br />Location <br />Building Height<br />Flush/Tilt;<br />Ballasted/Affixed<br />Residential: $5.50-$6.50/Watt<br />Commercial: $4.25-$5.25/Watt<br />(excluding NYC)<br />
