- Solar Grid Parity = cost of solar = grid electricity price
- Cost of Solar = cost of solar = grid electricity price
- Cost of solar ($/W) $6.40 $5.20 $3.75 U.S. Average (mid-2011)
- Cost of solar ($/W) $6.40 $5.20 $3.75 U.S. Average (mid-2011)
- Cost of solar ($/W)
- Cost of Solar Type Residential Cost per Watt $6.40 Levelized Location Minneapolis Cost per k Wh Project life 25 years 0 .37 Interest, Maintenance, etc $0.16/kWh Output (kWh/kW/year) 1,250

- Cost of Solar Levelized cost of solar installed at $4.40/Watt
- Grid Electricity Price = cost of solar = grid electricity price
- Grid Electricity Price Existing Power Plant per k Wh 0 .04 6/1/1970
- Grid Electricity Price Existing Power Plant per k Wh 0 .04 6/1/1970 Amortized power plant = new power plant
- Grid Electricity Price Market Price Referant per k Wh 0.12 OK for utility-scale solar (wholesale)
- Grid Electricity Price Retail Price va ries For on-site solar (retail)
- Grid Electricity Price Average residential retail rate (Feb. 2011, EIA)
- Solar Grid Parity 50% or better 95% to 105% 2011: 1 state 150% or more Ratio of solar cost to average residential retail rate
- Solar Grid Parity 50% or better 95% to 105% 2016: 3 states 150% or more Ratio of solar cost to average residential retail rate
- Solar Grid Parity 57 million people 50% or better 95% to 105% 2016: 3 states 150% or more Ratio of solar cost to average residential retail rate
