The Business Case for PV

  1. 1. The Business Case for PV BP 0802
  2. 4. Representative Current PV System Costs Grid Connected - No Batteries ($/Watt DC ) Item Module Hardware Inverter Install Total Retail High 6.10 (a) 1.00 .75 1.75 9.60 Retail Low 4.30 (b) 1.75 .75 2.40 9.20 Wholesale 3.50 (b) 1.40 .50 2.40 7.80 (a) Crystalline Si (b) Thin film a-Si Based on typical small system (<5.0 kW), 2000 catalog prices BP 0802
  3. 5. Total Installed PV System Costs – Representative Examples Residential: Range = $9.00 - $12.00 per Watt or $9,000 - $12,000 per kW Example: 2.0 kW DC system = $18,000 - $24,000 Commercial: Range = $7.00 - $9.00 per Watt or $7,000 - $9,000 per kW Example: 100 kW DC system = 100($9,000) = $900,000 500 kW DC system = 500($7,000) = $3,500,000 BP 0403
  4. 6. PV System and Energy Costs ($/kWh) ($/Watt AC) $10.50 8.50 6.00 4.50 Phoenix, AZ (6.5 PSH*) 0.26 0.21 0.15 0.11 Sacramento, CA (5.5 PSH*) 0.30 0.24 0.17 0.13 Spokane,WA (4.5 PSH*) 0.35 0.29 0.20 0.15 Phoenix,AZ (Tracker**) 0.20 0.17 0.13 0.10 Energy Cost (Cents/kWh) * PSH = average annual peak solar hours from NREL weather data; fixed tilt at Lat ** Single axis tracker increases generated energy by 34.4%; assume $1.00/W cost inc. System Cost BP 0802 Data based on computer simulation
  5. 7. Average Monthly Savings on Electric Bill per kW of PV DC ($/Month) City Sun Electric Utility Costs per kWh Hrs $0.08 $0.10 $0.12 $0.14 $0.16 $0.18 $0.20 Denver, CO 6.06 4.53 13.59 16.31 19.03 21.74 24.46 27.78 Kansas City, 5.01 8.76 10.95 13.14 14.24 16.27 19.71 20.34 MO Miami, FL 5.18 8.86 11.07 13.28 15.50 17.71 19.93 22.14 Phoenix, AZ 6.63 11.50 14.37 17.24 20.12 22.99 25.87 28.74 San Francisco 5.76 8.03 12.81 15.37 17.93 20.50 23.06 25.62 CA Seattle, WA 3.97 6.82 8.52 10.22 11.93 13.63 15.34 17.04 Source: “Home Power Magazine”, April/May 2003, pg31. NOTE: Does not consider tiered or time of use rate structure, which will greatly increase the savings.
  6. 8. PV System Costs SMUD Experience - 2000 Item Cost to SMUD ($/watt approx) Cost to retail customer ($/watt) Equiv. Energy cost (cents/kWh) Avg SMUD res rate (cents/kWh) Cost 4.25 2.40 6.7 8-12 BP 0802
