Average National Cost of Solar Panels

solar panel installation cost understanding expenses and factors involved

As of 2023, homeowners across the U.S. can expect to pay between $15,000 and $25,000 for the installation of a standard 6 kilowatt (kW) solar panel system, before incentives or rebates. It’s important to note this price includes both equipment and installation costs.

On a cost-per-watt basis, solar panel installations generally range between $2.50 and $3.50. These figures are national averages and can vary based on location, solar panel brand, and installation company.

Local labor rates, system design complexity, and additional features such as solar battery storage can also impact the total cost. Meanwhile, state and federal incentives, such as the federal solar tax credit, which allows you to deduct a significant percentage of the installation cost from your federal taxes, can substantially reduce overall expenses. Rebates and solar renewable energy certificates (SRECs) offered by states or utility companies further contribute to affordability.

Residential electricity consumption and household energy goals play pivotal roles in determining the appropriate system size and, consequently, the price. A smaller system suffices for lower energy use, leading to a reduced total outlay, while larger households may require more substantial installations.

Prices continue to fall as technology advances and solar panels become more widespread, contributing to the accessibility and adoption of solar energy systems. Investing in a grid-tied system can also result in net metering benefits, where excess electricity generated can be sold back to the grid, offsetting installation costs over time.

Factors That Affect Solar Panel Costs

The size and power output of the system directly impact cost, with larger installations requiring more panels and associated hardware. The type of solar panels selected is another critical determinant; monocrystalline panels are generally more efficient but also more expensive than polycrystalline options. Moreover, the complexity of the installation plays a role. Roofs with unconventional shapes or materials may necessitate special mounting equipment or additional labor, thereby elevating the price.

Additionally, the chosen installer affects cost, as reputable companies may charge more but also offer better warranties and service guarantees. Location is important too, as regional labor rates and the amount of sunlight received can affect system size requirements and cost. Lastly, available incentives and rebates vary by region, potentially reducing upfront expenses. Each of these variables can influence the final cost of solar panel installation and should be considered when evaluating quotes and options.

How Much Do Solar Panels Save?

Solar panels significantly reduce monthly utility bills, with average savings of $100 to $200 per month, although the exact figure varies based on local energy prices and solar power generation.

Net metering policies allow homeowners to sell excess energy back to the grid, potentially earning additional savings or credits.

The long-term savings from solar panels also depend on the efficiency and life span of the system, which typically lasts about 25-30 years.

Investment in solar power can increase a property’s value, with estimates suggesting a premium of around $15,000 for homes equipped with solar energy systems.

Solar renewable energy credits (SRECs) created for each megawatt-hour of solar power produced may offer additional income for solar panel owners in certain states.

Federal tax incentives, including the Solar Investment Tax Credit (ITC), can reduce the total system cost, enhancing overall savings.

By reducing reliance on the grid, homeowners with solar panels guard against future spikes in utility rates, securing more predictable energy costs over time.

Are Solar Panels Worth the Financial Investment?

The financial benefits of solar panels hinge on several dynamics. Initially, the reduction in electricity bills can be substantial over time, offsetting installation costs. Depending on energy usage and solar energy production, some homeowners may notice a break-even point within 7-10 years. However, this timeline can vary based on location, solar panel system size, and local electricity rates.

Incentives play a pivotal role as well. Federal tax credits, state incentives, and utility programs can significantly lower the financial burden. The federal solar investment tax credit (ITC), for instance, allows you to deduct a percentage of the solar system’s cost from your federal taxes, emphasizing the government’s encouragement for renewable energy adoption.

Increased property values further justify the investment. Homes with solar installations often sell at a premium, reflecting the future energy savings that come with the property. Moreover, solar panels can extend the life of a roof by protecting it from the elements.

Finally, investing in solar panels isn’t purely financial—it’s also an investment in the environment. The switch to renewable energy sources can reduce your carbon footprint, making it a conscionable choice for those looking to make a positive impact.


How much is a solar system for a 2000 sq ft house?

The net cost of a solar system for a 2000 sq ft house, after applying the federal solar tax credit, is around $20,000.

Do you really save money with solar panels?

Yes, homeowners can significantly save money on their energy bills, averaging around $1,530 annually, by installing a solar system.

Is it worth it to install solar?

Yes, it is worth it to install solar panels as the long-term savings typically outweigh the initial installation costs, despite the payback period potentially extending from a few years to several decades.

How long do solar panels last?

Solar panels typically have a lifespan of 25 to 30 years, with many reputable manufacturers offering production warranties to match this duration.

What are the ongoing maintenance costs for residential solar panels?

The ongoing maintenance costs for residential solar panels are usually minimal, often limited to routine cleaning and periodic inspection, amounting to approximately $150 to $330 annually.

Does incorporating solar energy increase property value?

Yes, incorporating solar energy typically increases property value due to its potential for saving on electricity costs and reducing carbon footprint.

What are the potential tax benefits of installing solar panels?

The potential tax benefits of installing solar panels include significant federal tax credits, often amounting to 26% of the total cost of the system, alongside various state-level incentives and local rebates.
