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.

The short answer: No, most solar panels don't work during power outages. . To keep your power on in a blackout, you need a solar inverter that can remove your home from the grid, along with a generator or battery for longer-term energy needs. By creating your own little “island” of a home with solar panels and batteries, you can run essential appliances for days during a. . But here's the surprise: If you have a standard grid-tied solar system, your panels will shut down automatically when the power goes out. Most grid-tied systems automatically shut down unless paired with a battery backup. Solar panels rely on sunlight to generate electricity, but what many people don't realize is that they are connected to the local electrical grid.
