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.
