2024 Solar Panel Cost Guide

Solar panels are available in a wide range of prices, from $17,500 to $24,500. In general, the average cost of a solar system with an average power of 7kW: around $19,390 USD or so. We've found that the price of solar panels is affected by a variety of factors, including your region, the size of your system, and the type of panels. Considering the many factors that affect the final price, knowing exactly what is likely to incur a cost will help you budget for solar panels for optimal energy savings.

Average Cost of Solar Panels

The cost of a 7kW solar energy system in the United States will vary by region. Based on 2023 data, the average cost is about $2.77 per watt, so the total cost of a 7kW system is about $19,390. After taking into account federal solar tax credits, the cost could drop to $14,349.1 However, this price does not include any additional state subsidies or incentives.

Specific to each state, for example:

In Arizona, the price range is between $14,490 and $18,130.
In California, the price range is between $16,800 and $20,860.
Data from other sources suggests that the national average cost may range from $17,500 to $24,500, with most homeowners paying about $21,000.2 Still others suggest that the average cost is about $14,000.3

Cost Analysis of Different Types of Solar Panels

When considering solar panels as a sustainable energy solution, it is crucial to understand the costs of different types of panels. The following will explore the cost of three different types of solar panels and provide some considerations when making a purchase.

Monocrystalline Solar Panel Costs

Monocrystalline solar panels are known for their high efficiency, but are correspondingly more expensive. According to market data, monocrystalline panels cost between about $0.50 and $1 per watt. Despite the larger initial investment, the long-term performance of monocrystalline panels may result in more energy savings.

Polycrystalline Solar Panel Costs

Polycrystalline solar panels offer a more cost-effective alternative. They typically cost between $0.30 and $0.80 per watt, and while slightly less efficient than monocrystalline panels, they may be a more affordable option for a home or business on a budget.

Thin Film Solar Panel Costs

Thin-film solar panels appeal to many consumers for their low cost and flexibility. At around $0.20 to $0.50 per watt, these panels are the cheapest of all types. However, they are also typically the least efficient, meaning that more area may be needed to produce the same amount of electricity.

When choosing solar panels, in addition to cost, other factors should be taken into consideration, such as the location of the installation, climatic conditions, available space, and expected energy demand. In addition, installation and maintenance costs are also important factors in determining the total cost.

What factors determine the cost of solar panels

Panel type

The type of solar panel is the primary factor that affects the cost. There are three main types of solar panels on the market today: monocrystalline, polycrystalline and thin-film panels. Monocrystalline panels are known for their high efficiency and stability, but are relatively expensive to manufacture. Polycrystalline panels, on the other hand, strike a balance between cost and efficiency, while thin-film panels are favored for certain applications due to their low cost and flexibility.

Scale of Production

Scale of production is also an important factor. Large-scale production can reduce unit costs because fixed costs (such as equipment depreciation and R&D inputs) can be spread over a larger number of products. In addition, purchasing raw materials in large quantities usually results in more favorable pricing.

Installation Method

The way solar panels are mounted also affects costs. Ground-mounted systems are usually less expensive, but may require more land resources. Rooftop mounting saves space but is more expensive to install. Floating mounting systems are an emerging technology for surfaces on bodies of water, and their cost varies with the maturity of the technology.

Geographic and Climatic Factors

Geographic location and climatic conditions have a significant impact on the cost and efficiency of solar panels. The intensity and availability of solar radiation determines the design of the panel and its ability to generate electricity. In addition, the tilt angle of the panels needs to be optimized for the geographic location to maximize energy capture.

Technology and Efficiency

The efficiency of solar cells is another key factor. Highly efficient panels can generate more power in a smaller area, but this usually means higher manufacturing costs. In addition, maximum output power tracking (MPPT) technology ensures that panels are always operating at their maximum power point, increasing the efficiency of the overall system.

System components and losses

The efficiency of other components in the system, such as solar inverters and controllers, as well as line losses and portfolio losses, can also affect the total cost of a solar panel system. Battery efficiency is especially important for systems that require energy storage.

Maintenance and Cleaning

Maintenance and cleaning of solar panels is also part of the cost. Dust and contaminants can reduce the efficiency of the panels, so regular cleaning is required to maintain optimal performance.

Markets and Policies

Market demand, policy support and supply chain security can also affect the cost of solar panels. Government subsidies and tax incentives can reduce procurement costs for users, while fluctuating raw material prices and supply chain disruptions can lead to higher costs.

Can Solar Panels Increase the Value of a Home?

Solar panels can add value to a home, but the exact amount of value added depends on a variety of factors, including geographic location, energy market trends, the quality and performance of the solar panels, the value of the home itself, and more. In general, solar panels can have a positive impact on potential buyers by increasing the curb appeal and sustainability of a home, but not all potential buyers will be willing to pay extra for them.

There are some studies and data that show that installing solar panels can increase the value of a home to some degree. For example, the National Renewable Energy Laboratory (NREL) once conducted a study that showed that for every dollar saved on electricity bills, the value of the property increased by $20. If a solar panel system saves you $1,000 per year, your property value will increase by $20,000. That's why homes with solar panels are usually able to sell for a higher price on the sales market. However, the exact amount of this added value will vary from region to region.

How Much Does a Solar Panel Roof Cost?

The cost of installing a solar panel roof varies greatly depending on several factors such as the size of the roof, the type and quality of the solar panels used, the cost of installation labor, the location, and other equipment needed (such as inverters and mounting hardware).

The average cost of a residential solar panel system in the U.S. typically ranges from $15,000 to $25,000 for a typical 5-kilowatt system, before any incentives or tax credits. Costs can be higher if the system is larger or the installation process is more complex.

It is important to note that there are often incentives available to help offset the cost of installing solar panels, such as federal tax credits, state and local incentives, and net metering programs. These incentives can significantly reduce the upfront costs and make solar energy more affordable for homeowners.
