Solar panels generate electricity from sunlight. A typical 6kW solar panel system for a 1,500 sq ft home costs around $16,500. Prices per watt range from $2.50 to $3.50, depending on the location and specific components. The advantages of solar PV systems include energy bill reduction and contributing to sustainability. The solar panels are securely mounted on your roof or another suitable location. Proper orientation and angle maximize sun exposure.
