Summary[edit]

Description
English: The break-even cost to install solar panels is a function of the amount of insolation, the cost of electricity, and the service life, assumed here to be 20 years. The map shows the break-even cost based on the insolation, in KWh/m²/day, or sun hours per day, times 365 days/year times 20 years times the average cost per kWh in each state. The numbers are an approximation, since cost and insolation vary within each state. Electricity cost is average residential for 2015 from the EIA.[1] The break-even cost is increased if electricity prices increase over time, or if any incentives are available, and reduced if maintenance and finance costs are included. For example, Nellis AFB is obtaining solar electricity for 2.2 ¢/kWh, from solar panels installed at a cost of $5.49/Watt, due to the sale of the Renewable Energy Credits. With the increases in electricity prices there are no states where solar is not cost effective, when the 30% tax credit is included. The map is essentially a combination of Us pv annual may2004.jpg and Average Retail Price of Electricity by State.jpg.
