Solar Panel and Battery Cost Guide
Residential solar is commonly priced per watt of system size, and published 2026 guides put typical installed prices at roughly US$2.40 to US$3.50 per watt before incentives, with Canadian guides landing in a similar range in Canadian dollars. A mid-sized home system therefore runs from the low tens of thousands to the mid-thirties.
Batteries, cleaning, inverter work and panel removal are priced separately. A single home battery with installation is a five-figure job. A cleaning visit is a few hundred dollars at most. An inverter replacement sits between those, depending on the type.
Treat the ranges below as a check on whether a quote is in a sensible area, not as a price list. Roof type, shading, local labour, permit fees and available incentives can all push a real quote outside them, and incentives have changed recently in several places.
Typical price ranges
- Home solar system (US)US$2.40 to US$3.50 per watt
A typical rooftop system before incentives. A 5 to 10 kW home system is roughly US$12,000 to US$35,000.
- Home solar system (Canada)C$2.40 to C$3.50 per watt
Installed rooftop system including panels, inverter, racking and labour, before incentives.
- Small commercial solar systemUS$1.40 to US$2.55 per watt
Rooftop systems from about 25 kW upward. Larger systems tend to sit at the lower end.
- Home battery, installed (US)US$11,500 to US$16,500
A single battery of about 13 kWh with installation, in a home with no major panel work.
- Solar panel cleaning, one visitUS$100 to US$350
A typical home array cleaned with soft brushes and purified water.
- Inverter replacement (US)US$1,000 to US$4,500
A string inverter on a typical home system. Microinverters are priced per unit, commonly US$300 to US$600 each.
- Panel removal and reinstall (US)US$100 to US$350 per panel
Detach and reset for a re-roof on a standard sloped roof. Tile and permit fees add to it.
Typical 2025-2026 US and Canadian ranges compiled from published guides including Inch Calculator, EnergySage-based summaries, NRG Clean Power, Green Building Canada, NuWatt, Green Lancer, LawnStarter, SolarReviews and HomeGuide. Many are installer-run, sources disagree, and local quotes vary with roof, region and incentives, so use them as broad starting points.
What drives the cost
- System size and equipment
- More watts cost more in total, and premium panels, microinverters and optimizers raise the price per watt.
- Roof type and condition
- Tile, slate, steep and complicated roofs cost more to mount, and an old roof may need work first.
- Shading and orientation
- Shaded or poorly oriented roofs may need fewer panels in the best spots or extra equipment.
- Electrical upgrades
- A main panel that is full or outdated may need upgrading before solar or a battery can connect.
- Permits and utility rules
- Fees, inspection steps and interconnection charges vary by municipality and utility.
- Incentives and net metering
- Credits, rebates and the rate paid for exported power change over time, so they change the payback more than the price.
- Local labour market
- Metro areas and busy seasons tend to cost more than quiet markets.
- Battery and backup scope
- Backing up a few circuits costs less than whole-home backup.
Ways to keep the cost down
- Gather at least three written quotes with the same system size so that you can compare equipment and output line by line
- Have the roof replaced before panels go up if it is near the end of its life, so panels do not have to come off later
- Size the system from twelve months of bills instead of a template, so you do not pay for panels you will not use
- Check which local incentives or credits are available at the time you sign, and make sure the quote states them
- Keep panels clean and the system monitored so small faults are fixed before they cost production
Cost questions
How much does it cost to install solar on a house?
Most published guides put it at roughly US$2.40 to US$3.50 per watt before incentives, which gives about US$12,000 to US$35,000 for a typical home system. The exact figure depends on size, roof, equipment and location.
Is a solar battery worth the cost?
It depends on your goal. For backup during outages it can be worth it. For savings alone, it depends on your utility's rates and what you are paid for exported power, and a good quote will show both.
How much does solar panel cleaning cost?
A typical home visit is a few hundred dollars at most, with many guides showing about US$100 to US$350. Larger or harder-to-reach arrays cost more.
Why do solar quotes differ so much?
Quotes can use different panels, inverters, roof work, warranties and system sizes. Compare cost per watt and expected yearly output, not only the total.
