The number of panels purchased at one time usually affects the price. This means that buying a 2,000-watt solar panel system may be more expensive than a 10,000-watt solar panel system. This is because bulk purchases can reduce the cost of panels, like bulk food or other products.
The cost of purchasing and installing solar panel ranges from $2.67 to $3.43 per watt (for cash purchase). The price of the entire system is based on its capacity in watts. How many systems you need will depend on the energy you use, daylight on the roof and panel efficiency.

The average payback period for residential solar systems is 6 to 9 years, depending on system costs, incentives, and energy cost savings.
