The Price of Residential Solar Power

Solar costs have declined significantly, and are at their lowest point in over 30 years. Solar is now more affordable than ever and advances in technology have improved system quality and design.

On average the total cost of solar installation can be between $15,000 to $29,000 for average sized systems sized between 4kW and 8kW.2 Sunrun solar lets you get started for as little as $0 down and helps you lower your electric bill.

If you want to own your system, we do that too. If you choose to buy your system, the graph shows an average breakdown of costs of a residential solar panel installation.

Do you own your home?

When you purchase a residential solar system, the cost of your system also depends on its size. Larger systems will cost more as they require more panels.

A photovoltaic system is more than its panels — it's made up of many other components, including wiring, racks, an inverter, and often a solar monitor and meter. The balance of systems and installation labor costs can drive up the overall cost-per-watt of a system.

Solar is More Than Just Panels

Your home solar system cost is not based solely on the price of solar panels. It is calculated based on a number of other components, including wiring, racking, an inverter, and a solar monitor. When you purchase a solar system, your solar panel installation costs and material costs will depend on your system's size.

The typical home solar system size is approximately 5 kilowatts (kW).  Some households will need larger systems to meet the energy needs of the home.
