Photovoltaics – Practical Information • ApproxSouth Facing Roof or field • Roof angles from 20-50 degrees • Less than 200’ from loads • Every 70 square feet of area can yield up to 1000 kWh per year in New Jersey • 90% solar window required • Each 1 kW-DC installed can yield about 1200 kWh annually
PV Module Prices (still around $4/watt) Source: P. Maycock, The World Photovoltaic Market 1975-1998 (Warrenton, VA: PV Energy Systems, Inc., August 1999), p. A-3.
Economic Value: a NJ Farm • PV Systems would have 25-30 year payback without CORE rebates from NJBPU or SRECs from the NJ Market • With NJCEP Rebates and/or SRECs the payback reduces to less than 10 years • PV Systems can produce between 1100 and 1350 kWh per installed kW annually across New Jersey • Today’s Pricing: $6.50-$8.00/Watt depending on size
Solar panels - BP 4175 • Rated Power : 175 W • NOCT : 47 C • Length : 1.58 m • Width : 0.808 m • maxP Voltage : 35.2V • maxP Current : 4.95A
