At the time of this writing, the installed cost of solar panels was between $7-$9 per watt: A 5 kW system would cost around $25,000-$35,000. Many utility companies offer incentives, and some subsidize as much as 50% of system costs.
Wind power, for example, costs about $80 per megawatt-hour of electricity when the lifetime costs of building a new project are factored in, according to the Energy Information Administration. Solar is closer to $130 per megawatt-hour.
