According to the EnergySage Solar Marketplace, the average cost of a solar photovoltaic system in 2021 is between $15,000 and $25,000 for a 6kW system after the federal tax credit. However, the cost of a solar photovoltaic system can vary based on several factors, including the size of the system, the type of panels, and the installation complexity.
Factors that Affect the Cost of a Solar Photovoltaic System
When determining the cost of a solar photovoltaic system, several factors come into play. These include the size of the system, the type of panels, the quality of the components, and the complexity of the installation. Additionally, the location of the installation and local labor costs can also impact the overall cost.System Size
The size of the solar photovoltaic system is one of the primary factors that determine its cost. The larger the system, the more expensive it will be. Most residential solar systems range from 3kW to 10kW, with the average system size being around 6kW. Larger systems are typically more expensive due to the additional panels and components required.Panel Type and Quality
There are several types of solar panels available on the market, ranging from monocrystalline to polycrystalline and thin-film panels. The type and quality of panels chosen can affect the cost of the system. Generally, higher efficiency and more durable panels will come at a higher cost upfront but may provide better long-term performance and savings.
