But, by 2016, Deutsche expects solar energy to reach price parity in all 50 states. For example, the cost of solar-generated electricity in the top 10 states for capacity ranges from 11-15 cents per kilowatt hour (c/kWh), compared to the retail electricity price of 11-37 c/kWh.
Capital costs. A kilowatt is a unit of electrical power capacity. According to a U.S. Energy Information Administration, or EIA, report published in April 2013, the cost of building a utility-gradeâgreater than 150 MW (megawatt)âsolar power plant was $3,873 per KW (kilowatt). solar power plant is one of the cheapest to operate because there are no fuel costs involved. A solar PV (photovoltaic) power plant requires fixed expenses of $11.40 per megawatt hour, or just 1.14 cents per unit.
