Most homeowners spend between $12,600 and $33,376 to install a complete residential solar system in 2026, with the national average at $19,873 before incentives. Your actual cost depends on your home's energy needs, roof characteristics, location and other factors, all of which we'll break down in this guide.
These costs are for a typical 7 kW residential system ($19,873 average). Monocrystalline or polycrystalline panels are the most common types of solar panels. Most residential installations use monocrystalline photovoltaics (PV) panels, which offer up to 24% efficiency and perform better in limited space and extreme temperatures.
Monocrystalline solar panels are the most popular choice for residential installation (nearly all residential solar panels installed in 2022 were monocrystalline) because they have the highest efficiency rates from 17% to 22%. The average cost for these panels is between $1 and $1.50 per watt, but prices may differ depending on location.

In 2025, the typical cost of commercial lithium battery energy storage systems, including the battery, battery management system (BMS), inverter (PCS), and installation, ranges from $280 to $580 per kWh. Larger systems (100 kWh or more) can cost between $180 to $300 per kWh. How does battery chemistry affect the cost of energy storage systems?
In 2025, the typical cost of a commercial lithium battery energy storage system, which includes the battery, battery management system (BMS), inverter (PCS), and installation, is in the following range: $280 - $580 per kWh (installed cost), though of course this will vary from region to region depending on economic levels.
Different places have different energy storage costs. China's average is $101 per kWh. The US average is $236 per kWh. Knowing the price of energy storage systems helps people plan for steady power. It also helps them handle money risks. As prices drop and technology gets better, people need to know what causes these changes.
In 2025, they are about $200–$400 per kWh. This is because of new lithium battery chemistries. Different places have different energy storage costs. China's average is $101 per kWh. The US average is $236 per kWh. Knowing the price of energy storage systems helps people plan for steady power. It also helps them handle money risks.
