Cost of a typical private solar system cost

  • Request price quotes from several installers. According to Consumer Reports, a typical solar system can run between $10,000 - $50,000, depending on household needs, installation requirements and the size of the system.
  • Be sure to explore available tax incentives and rebates for your area.
  • If installing your own system, be sure to check out steps you must take to participate in LG&E and KU’s Net Metering Service.

Cost of a typical system over its lifetime

U.S. News and World Report recommends you first consider the “all-in” costs, or levelized costs, to produce electricity using a private solar system over its lifetime.

To determine the levelized costs of a solar system, add together the costs to buy, install, finance and maintain the solar system over its expected lifetime; then, divide the “all-in” total costs by the total amount of electricity the solar system is expected to produce over its lifetime.
