How Much Does a Home Solar System Really Cost in 2025?

EcoFlow

Home solar systems can help you slash utility bills and increase energy independence, but they require a significant upfront investment. While initial costs can be high, solar starts to pay for itself as soon as the system is up and running. So, how much does it really cost to install a home solar system in 2025?

Below, we’re breaking down the numbers from equipment to installation and all the opportunities to save.

How Much Will Solar Cost in 2025?

In 2025, the average residential solar panel system in the United States (including equipment and installation) typically costs between $25,000 and $45,000 before incentives, depending on system size, location, and installer rates.

That range can drop drastically after applying the 30% federal solar tax credit. However, this is only the starting point. Home size, roof condition, panel type, and battery storage significantly influence the final cost.

Solar costs are highly personal, so the best way to know how much it would cost to install solar at your home is to get a quote or determine the system size you’d need if you prefer to DIY it. 

Solar Installation: A Guide

Installing a home solar system isn’t just about the panels. It’s a process that involves selecting the right components, assessing your home’s energy needs and ensuring your system can satisfy them, working with contractors (or DIYing), and understanding local regulations and permits.

The two most significant components you pay for are the equipment and the installation (labor costs). While DIYing the process can save on labor, it requires much more time and expertise.

Here’s an overview of the must-have equipment and how installation costs impact the total price.

Essential Equipment

When you see each piece needed to create a solar system, you’ll better understand where your money is going.

Solar Panels

Panels are the core of any solar system and account for around 12% of its total cost. In 2025, panel prices are around $2 to $3 per watt, depending on efficiency, brand, and warranty. A typical 6 kW system might cost $15,000 just for panels.

Inverters

Inverters are critical if you want to use the power your solar system generates. Your inverter will convert DC electricity (from your panels) to AC electricity (for your home). Depending on the type you choose, a quality inverter will cost $1,000-$2,500.

String inverters pull the DC power from all panels to a central location and convert it there, while a microinverter converts it to AC at each solar panel. Hybrid models combine an inverter and charge controller system, ideal for battery storage.

Mounting Systems

Racking and mounting hardware keep your EcoFlow Rigid Solar Panels secure and angled correctly. Expect $500-$2,000 for roof mounts or $2,000-$4,000 for ground-mounted systems. Mounting systems only account for around 3% of the total cost, but can add up for large systems.

Battery Storage

If you want energy storage for blackout protection or off-grid capability, a solar battery can cost anywhere from $3,000 to $20,000, including installation. For whole-home backup, you may need more than one. The battery storage component can easily be the largest cost. Still, it also provides the most significant benefit and allows you to maximize the use of your solar system. 

It’s also required if you want to go off-grid, as you would otherwise need central grid power to get your system working. Off-grid applications need a battery large enough to support the whole home, like the EcoFlow DELTA Pro 3, which offers capacity up to 12kWh with extra batteries.

Installation Fees

Labor costs for professional installation typically range from $3,000 to $10,000, depending on system size, roof pitch and structure, and regional labor rates. These fees usually include electrical work, permitting, and inspections.

DIY Installation vs. Professional

DIY solar installation can save a few thousand dollars but comes with trade-offs. You'll need electrical expertise, permits, and inspections, and may not get the same warranty as a professionally installed system. Professional installers know exactly what they’re doing and ensure compliance with building codes, saving you time and headaches.

Consider this: if you install the system yourself, you’ll still have to pay for these tools and costs separately:

  • Safety gear: ~$500

  • Solar design software: Free to ~$200

  • Permitting: $300-$1,000

  • Additional wiring and mounting hardware: Varies

Unless you're highly experienced, professional installation is usually worth the investment.

Key Factors Influencing the True Cost of Going Solar

All the above costs are estimates, and every home’s solar power system cost will vary. Each project is unique in size, location (including regional costs), energy output, roof size and structure, panel type, and battery storage.

You may not be able to control all of these factors, but understanding how they impact the cost allows you to pinpoint key cost drivers.

Home Size

While not a hard and fast rule, the square footage of your home generally correlates with your electricity usage. Larger homes require more power to support heating, cooling, appliances, and lighting, so they need more solar panels to meet those energy demands. A bigger system costs more upfront but can offset a higher monthly utility bill, leading to greater savings over time. On the other hand, smaller homes require fewer panels and may offer quicker payback periods, helping you recoup your costs in just a few years.

Location

Geographic location impacts both installation costs and solar energy production. If you live in a sunny region like Arizona, Florida, or Southern California, your panels will produce more electricity per watt than in cloudier areas like the Pacific Northwest. 

Labor and permitting costs also vary widely from state to state. In places with high solar adoption and competition among installers, you may pay less for the same system than in less-saturated markets where one or two installers have a greater hold over the market. Your local cost of living and regulations will also affect labor fees, permitting, and inspection expenses. Bigger cities tend to have higher labor costs than suburban or rural areas, which can be reflected in costs beyond the panels themselves.

Energy Use

The more electricity you use, the more capacity your solar system will need to match or offset your consumption. If you have an electric vehicle, a heated pool, or a large family, your home likely has a high energy demand and will need larger and more expensive solar arrays. 

On the flip side, homes with efficient appliances and good insulation might require fewer panels, reducing costs. Performing an energy audit before installing solar can help you size your system appropriately and avoid overspending.

Your habits also impact energy use. Sustainably-minded families that turn off the lights when they leave a room, unplug electronics when not in use, turn up the AC temperature when leaving the house, and avoid leaving windows and doors open will use less energy than families that aren’t as strict in their energy-saving behaviors.

Habits are one thing you can control. So, if you’re looking to cut costs on solar, consider how you can make a few lifestyle adjustments to bring your total required wattage down.

Roof Size

Your roof’s size, shape, pitch, and orientation affect how many panels you can install, how easy they are to install, and how efficiently they’ll perform. In the U.S., a large, south-facing roof with a 30-45° pitch is ideal to maximize sunlight exposure. 

If your roof is shaded or has multiple levels, installing panels is more complex and potentially more expensive. In these circumstances, you may need a custom racking solution, panel optimizers, or even ground-mounted panels, all of which increase your total system cost.

Solar Panel Type

Some solar panels are more expensive, but also more efficient, allowing you to make back your investment sooner. Others are cheaper upfront, saving you cash, but don’t perform as well. The choice is yours.

Monocrystalline panels are the longest-lasting, most efficient, and expensive. They usually range from $1.00 to $1.20 per watt. Polycrystalline panels cost less (around $0.90 to $1.00 per watt) but are slightly less efficient, requiring more roof space for the same output. Thin-film panels are rarely used in residential settings due to their lower efficiency, but they may be an option for specific projects. 

Pro Tip: Investing in high-efficiency panels can be more cost-effective in the long term if roof space is limited or future energy needs grow.

Battery Storage

If you choose to include it, battery storage becomes a massive percentage of a system’s total cost, often adding anywhere from $3,000 to $20,000, depending on capacity and brand. 

Still, they’re worth it. Batteries provide critical benefits: they store excess solar energy you can use during power outages, at night, or during peak utility rate times. In some areas with time-of-use billing, batteries can also reduce your reliance on the grid when electricity is most expensive. 

If you’re not ready to commit to a large home battery, consider something smaller like the EcoFlow DELTA 3 Series Solar Generator. It offers 1-5kWh expandable capacity and includes a 220W Bifacial Portable Solar Panel, so you can take your generation and power capabilities on the go with you.

Though they’re not essential for every homeowner, battery storage is crucial if you seek energy independence, blackout protection, or off-grid capability. Many states also offer incentives for batteries, either included in solar incentives or available as a separate way to save, which can help offset the additional cost.

Average Total Cost of a Home Solar System

Considering all aspects of the system (panels, inverter, mounting equipment, installation costs, permits, etc.), a whole-home solar system will cost between $25,000 and $40,000 in 2025. 

This cost does not include the savings from solar incentives, but it also does not include battery storage if that’s something you want to add. 

At the end of the day, solar is an investment, not an expense. The high up-front costs are quickly chipped away via monthly savings on your electric bill. If you have an off-grid system with a battery, you may not even have a bill anymore! Over time, you’ll make your money back and then some.

2025 Solar Incentives: Tax Credits, Rebates, and Savings

As of 2025, the federal Investment Tax Credit (ITC) is 30% for residential systems. You can deduct 30% of your solar installation costs (including battery storage) from your federal taxes. For a $20,000 system, that's a $6,000 credit. The more you spend, the more you save.

State and local incentives can reduce your costs even further. These might include:

  • Cash rebates

  • Sales tax exemptions

  • Property tax abatements

  • Performance-based incentives (PBIs)
     

Check your state’s energy office or DSIRE database for current state incentives for renewable and efficiency upgrades in your area.

10 Tips on Saving Money on Solar

  • Compare multiple quotes: Meet with a few installers and compare estimates to get the best deal.

  • Choose the right system size: Don’t overspend on excess capacity unless you have specific plans for your energy use to increase (buying an electric car, getting a pool heater, adding more people to the house).

  • Buy during off-season sales: Winter can be a great time to shop for deals.

  • Bundle battery storage with solar: If you want to get the most from your system and qualify for bigger incentives, include battery storage in your quotes.

  • Check warranties carefully: Longer is always better. See if your installer offers warranties in addition to the manufacturer’s warranties.

  • Avoid unnecessary add-ons: Don’t get caught up in add-on sales tactics unless they directly benefit your goals.

  • Ask about financing options: If upfront costs are challenging, explore other ways to save, such as solar leases, loans, or power purchase agreements (PPAs).

  • Maintain optimal panel efficiency: To ensure peak performance and efficiency, keep your panels clean with quarterly or bi-annual cleaning and trim trees that create shade on them as needed.

  • Ask about referral bonuses: If you’re happy with your installer, ask if they offer any incentives for referring friends or neighbors to them. This can help you recoup a few hundred dollars while ensuring loved ones work with a reputable installer.

  • Buy American-made panels: Some state or local programs offer additional rebates for purchasing American-made panels or other components.

Frequently Asked Questions

How Many Years Can You Claim the Solar Tax Credit?

You can only claim the solar tax credit in the year your system was installed and began operating. The only exception is if your tax liability is lower than your credit; in that case, you can roll the credit over and claim it as soon as your tax liability is higher than your credit.

What Is the Solar Tax Credit for 2025?

In 2025, the federal solar tax credit in the US is 30% of the total cost of your system, including equipment (and battery storage), labor, and permits/fees. Unless the federal government changes the policy, the current legislation will run through 2031.

How Many Solar Panels are Needed To Run a 2000 Sq Ft House?

Most 2,000 square-foot homes use around 900-1,200 kWh per month. To meet this energy need, you’ll need around 14-17 panels (assuming each panel is around 400W and adequate sunlight conditions). If you have an energy-intensive home or live somewhere sunlight is scarce, you’ll need more panels.
