What is the All-In Price to Install Solar Panels?

Even though the average cost of solar panels has dropped 80% in the last decade, the upfront cost is still significant. When selecting the best solar company for your home installation, price is one of the largest factors.

To answer this question, let’s take a look at the basic price range for solar panel installations. The average cost for solar equipment in the U.S., based on our analysis, is around $3.33 per watt.

To put this in perspective, this means that after the 30% federal tax credit is applied, a 5-kW system would cost $11,655 and a 10-kW system would cost $23,310. An average residential solar system would sit somewhere between those figures.

Next, you might rightly wonder: What exactly am I paying for? The solar panels themselves usually make up just about a quarter of the total system cost. Remaining expenses include labor costs, solar maintenance and additional parts and equipment (such as inverters, racking, wiring, electric vehicle chargers or batteries).

Cost of Solar Panel Maintenance

In general, solar systems are designed to run smoothly for decades without requiring much maintenance or upkeep. However, even the best systems require routine solar panel cleaning and checkups as grime, dirt and debris can accumulate over the solar cells.

Any sizable costs associated with malfunctioning panels should be covered by your panels’ warranty, but it’s not a bad idea to factor in the costs of a simple few cleanings and occasional maintenance.

What Solar Financing Options are Available?

Different solar installers may offer different financing plans, allowing you some flexibility. With that said, there are three standard options for paying for your solar energy system:

    1. Purchase your solar energy system outright (that is, pay in cash).

    1. Take out a solar loan to purchase the system, then pay it back with interest.

    1. Lease your solar system; you will pay less month to month but won’t actually own the system yourself.
    2. Take on a solar PPA, simialr to a lease but you don’t own any of the system but benefit from solar energy it creates at a small cost.

Our solar financing guide breaks down each of these options to help you make the decision that best fits your needs and our solar leasing vs buying guide can help you decided if either of those options is right for your solar needs.

How to Find the Lowest-Price Solar Panels?

Again, the best way to assess the cost of solar is to get a quote from a certified installer near you. In addition to receiving an installation price, you can learn your estimated 25-year energy costs, how compatible your home is for solar and even compare quotes to find the best offer. The simple process of getting quotes from multiple providers can save you thousands in the long run.

What Are the 5 Key Factors of the Price of Solar Panels?

There are a few key factors that lead to variation in solar installation costs. Understanding these can help you decide whether solar panels are worth the investment for your home. Let’s take a look at them in more detail.

System Size Needs

The size of your residential solar system will depend primarily on the amount of electricity you currently use. You can roughly estimate how many photovoltaic (PV) solar panels you’ll need based on past utility bills, your available roof space and the amount of sunlight in your area, but to get an accurate system size, you’ll need a consultation with a local solar provider.

Your installer will evaluate your home energy needs based on irradiance maps, energy bills, satellite imagery of your roof, your utility company and more. It can then recommend a custom solar panel system size to accommodate your energy needs. The larger the system, the more expensive it will be.

Type of Solar Panels and Other Equipment Costs

There are three basic types of solar panels, two of which are commonly used residentially: monocrystalline and polycrystalline panels. Monocrystalline panels tend to be more energy-efficient, which can lead to greater savings in the long run, but they’re also a bit pricier on the front end.

That being said, solar panel efficiency is the name of the game for most homeowners who aim to install a system on their roof, as they’ll likely have less space to work with than commercial solar projects or ground-mounted solar panel systems will.

Other components you may need to purchase include inverters, wiring, charge controllers, mounts, solar batteries and more. Consider how much backup power is a priority for your home – backup batteries will add some costs on the front end, but additional safety and savings on the back.

Geographic Location

Another factor that can have a big impact on solar pricing? Where you live. Unsurprisingly, solar installation tends to be most cost-effective in parts of the country that get a lot of sun exposure, and therefore more energy to convert into electricity. This basically means that solar panels will operate more efficiently and, in many cases, means that you’ll need fewer panels overall to power your home.

Those who live in states like California, Florida and Arizona — or really any areas of the Sun Belt or Southwest — will likely get the most out of their home solar power systems. Other factors like the direction of your home and how much shade your house gets will also impact your home’s sun exposure, and therefore the efficiency of your system. Also, keep in mind that the further your company is from your home, the more expensive the overall installation will be. Find your state in our hub for solar panels installation guides where we detail the 7 steps to installing solar panels in your state.

Solar Incentives

Both state and federal governments have established incentive programs to encourage homeowners to buy solar panels. There is currently a 30% federal solar tax credit, called the Solar Investment Tax Credit (ITC), available for homeowners who install residential solar panels through 2032. It is scheduled to reduce to 26% in 2033 and 22% in 2034 before expiring in 2035.

Your solar system cost will also depend on the net metering policy of your local utility company. Most utilities vary in their buyback rates and feed-in tariffs, but policies can have a big effect on the overall value from your solar system and your solar payback period. Be sure to ask your solar installation company about how cooperative your utility provider is with solar energy installations.

State incentives, rebates, and solar tax exemptions can certainly vary based on where you live, but most solar panel installers should help you identify and apply for the programs in your area. However, it’s still a good idea to familiarize yourself with the local incentives that might be available to you.

Additional Factors of Solar Panel Installation Prices

There are plenty of other factors that can impact solar panel installation costs. These include (but are not limited to):

    • The availability of solar panels in your area

    • Your monthly electricity bill/energy usage

    • The current cost of shipping

    • The number of providers competing for your business

    • Supply chain issues

    • Local electricity rates

The bottom line? You can learn the most by shopping around. Get a few different proposals from local companies, evaluate what services you might be interested in and ask about sales or specials. Familiarize yourself with the best brands of affordable solar panels if budget is your priority.

Make the Best Choice About Solar Energy

Solar energy is not right for every homeowner, nor for every home. With that said, many homeowners will find that the total cost of solar is more than offset by long-term, recurring energy savings that provide a sizable return on investment. Make sure you factor in cost, energy needs, tax incentives, home value, energy storage options, and more as you seek to make a fully informed decision about whether to make the switch to renewable energy with solar.

Which States Have the Best Solar Panel Costs?

One of the broadest ways to gauge the overall cost of solar is by looking at the average price of solar panels by state. Our statewide average prices are calculated using market research and data from top brands. These prices can help convey a better understanding of what solar might cost in your area.

*solar panel system sizes are measured in kilowatts (kW), which indicates the maximum amount of energy they can produce at a given time

Keep in mind that 5 kW is a baseline size and near the smaller end of most solar panel installations. Larger homes may require 6 kW systems, or larger.
