On average, with federal solar incentives factored in, a professionally installed 5kW solar system (a common residential size) with high-quality solar panels will cost:
$5500-$8000 for a string inverter system
$8000-$9500 for microinverter system

The average residential solar system will pay for itself within 3-5 years in the form of lower electricity bills.
