How much do solar panels cost?
Solar panels cost between $0.30 and $0.90 per watt without labor and other fees. Since your typical solar panel system size is 6.5 kW, anticipate spending around $3,900 for the panels alone, or somewhere between $1,950 and $5,900. However, system sizes range from 3 kW to 11 kW, so you could see prices for as little as $900 or as much as $8,800.
Are solar panels expensive?
