Solar panel replacement cost is typically $500 to $1,000 for one damaged panel installed in the United States. The panel itself may cost about $200 to $550. Labor, roof access, electrical testing, service fees and disposal make up the rest.
For a full system, the 2026 U.S. installation benchmark is about $2.60 per watt before incentives. That puts a complete replacement at roughly:
| Replacement project | Typical U.S. cost |
|---|---|
| One panel, installed | $500 to $1,000 |
| Several panels | $1,000 to $5,000 or more |
| 6 kW complete system | About $15,600 |
| 8 kW complete system | About $20,800 |
| 10 kW complete system | About $26,000 |
| 12 kW complete system | About $31,000 |
| Remove and reinstall panels for roof work | $1,500 to $6,000 |
The full-system figures use current installation pricing as a guide. A replacement can cost less when the existing racking, wiring and inverter remain compatible. Older systems may need new electrical equipment or a complete redesign.
Solar Panel Replacement Cost by Project Type
Replacing One Damaged Solar Panel
A one-panel job can carry a high per-panel cost because contractors may charge a minimum service fee. The final price can include:
- Diagnosing the problem
- Accessing the roof
- Disconnecting and removing the damaged panel
- Installing the replacement
- Testing the panel and system
- Disposing of the old equipment
The price may rise if the panel is on a steep or difficult-to-access roof. A connected microinverter may also need testing or replacement.
Replacing Several Panels
Replacing several panels usually costs $1,000 to $5,000 or more, depending on the number of panels, roof access and the condition of the mounting system.
A three-panel replacement may involve:
- Three replacement modules
- Roof access and removal labor
- Electrical disconnection and reconnection
- New clips, connectors or wiring
- System and monitoring checks
- Permit or inspection fees, where required
The cost per panel may fall when the contractor can complete the work during one visit.
Replacing the Entire Solar Panel System
A full replacement is more likely when the array has widespread damage, the panels are near the end of their service life or the system uses equipment that is no longer available.
EnergySage's 2026 marketplace data puts the average new residential solar installation at about $2.60 per watt before incentives. Its average 12-kilowatt system costs about $31,135.
A complete replacement may cost less than a new installation if the roof attachments, racking, wiring and inverter can be reused. New panels still need to match the existing electrical equipment. Mixing older and newer components can create compatibility or performance problems.
What Adds to the Cost of Replacing Solar Panels?
Several parts of the job can push the quote higher:
- Roof access: Steep, high or difficult-to-access roofs require more labor and safety equipment.
- Equipment removal: Disconnecting and removing panels, mounting hardware and wiring adds labor.
- Inverter compatibility: New panels must work with the existing string inverter, power optimizers or microinverters.
- Roof repairs: The roof should be repaired before new panels are installed.
- Permits and inspections: Local authorities or utilities may require approval for electrical changes.
- Monitoring updates: The installer may need to update the monitoring system after the replacement.
- Older equipment: An older array may need new connectors, wiring, racking or an inverter.
- Storm or fire damage: Insurance may cover some of the work, depending on the policy, deductible and cause of damage.
Removing and reinstalling an array during a roof replacement commonly adds $1,500 to $6,000 to the roofing project.
Check Whether the Inverter Is the Real Problem
A sudden drop in solar production does not prove that the panels need replacing. The fault may be in the inverter, wiring, monitoring system, shading or a failed connection.
Angi lists these typical inverter replacement costs:
- String inverter: $800 to $2,500
- Microinverter: $150 to $350 per unit
Have a professional test the system before approving panel replacement. Replacing working panels will not fix an inverter or wiring fault.
Can a Solar Panel Warranty Cover Replacement?
A warranty may cover a defective panel, but it may not cover every installation expense. Solar systems commonly have separate warranties for:
- Panel manufacturing defects
- Minimum electrical output
- Inverters
- Racking
- Labor
Many panels have product warranties lasting at least 10 years. Performance warranties commonly last 25 years. Manufacturers may still exclude labor, shipping and contractor service fees.
Hail, falling branches, wind and fire may fall under homeowners insurance instead. Check the policy and deductible before scheduling the work.
Is It Better to Repair or Replace Solar Panels?
Repair is usually the better option when the problem is limited to wiring, a connector, a fuse or minor equipment damage. Replacement makes more sense when:
- The panel has extensive glass or cell damage.
- The panel no longer produces power.
- Several panels have failed.
- The system is near the end of its service life.
- Replacement parts are unavailable.
- Repair costs are close to the price of a new panel.
Solar panels commonly operate for about 20 to 30 years. Many still produce at least 80% of their original output after 25 years. The U.S. Department of Energy recommends keeping a functioning system in service unless production has declined substantially or the equipment is damaged.
Are Federal Solar Tax Credits Available for Replacements in 2026?
The federal Residential Clean Energy Credit is not available for solar expenditures made after December 31, 2025. A solar panel replacement installed in 2026 does not qualify for the former 30% federal residential credit.
State, utility and local incentives may still be available. Check the programs in your area before signing a replacement contract.
How to Get an Accurate Replacement Quote
Ask the solar contractor to list each part of the work separately:
- Diagnosis and inspection
- Replacement panels
- Removal and disposal
- Labor and roof access
- Wiring, connectors and mounting hardware
- Inverter or optimizer replacement
- Permits and inspections
- System testing and monitoring updates
For one failed panel, a budget of $500 to $1,000 is reasonable. For an aging or badly damaged system, compare the repair quote with a complete replacement based on the current $2.60-per-watt installation benchmark.
