2021 Solar Inverter Replacement Cost | Top Inverter Brands

Solar inverters are complex systems that can be prone to problems and eventually wear down and need to be replaced. In this guide, we’ll show the current 2021 solar inverter replacement costs for the top solar inverter brands.

Fronius Inverter Replacement

Austrian brand Fronius is one of the leading manufacturers in the market when it comes to photovoltaic electronics and solar inverters and accessories. Fronius solar inverters are known to be efficient and reliable which makes them perfect for residential and commercial uses. The introduction of the brand’s SnapINverter series (Primo and Symo) was pivotal in Fronius’ emergence as a leader in solar inverters.

When Fronius inverters encounter problems, it will be displayed as fault codes that pertain to certain problems. In the SnapINverter series, the common fault codes displayed are ‘state 461’ and ‘state 457’ which signify problems in the software that only needs to be updated. However, if the solar inverter displays fault codes other than these two, then it might mean that the whole inverter needs to be replaced.

Fronius inverters are also accompanied by a 5-year warranty. Currently with an extra 5 year promotion warranty ending December 2021.

Fronius Primo Cost

Fronius Primo solar inverters are one of the best for residential installations. These are reliable single-phase string inverters with a unique snap-in design and a great interface that is user-friendly. Their performance reliability stems from the “active cooling” system which is a feature that prevents the inverter from overheating by extracting heat at a high rate, efficiently reducing thermal stress to improve performance. Primo inverters have a range of power ratings from 3.0kW to 8.2kW.

If you are looking to replace your residential Fronius Primo inverter, expect to spend between $1800 to $3000 for supply and installation.

What’s the Cost of Removing and Replacing Solar Panels?

Solar panels need to be properly handled when it comes to removing and replacing them as they are very delicate. They have electrical wirings that might cause further problems if they are not properly handled or are not serviced by a professional. If the work is done by yourself, you also need to take extra precautions to avoid falling from the roof. However, the best way to remove and replace solar panels is to hire the services of a professional.

The cost of removing solar panels depends on several factors:

  • Removal or uninstalling of mounting hardware
  • Shipping and storage of materials
  • Cleaning of solar panels
  • Fixing or replacing the roof


The average cost of removing solar panels ranges from $1,800 to $3,000 or even higher depending on the factors mentioned and even on the size and number of solar panels.

If solar panels have been badly damaged, it is more efficient to replace them than fix them. The average cost of replacing solar panels can range from $15,000 to $30,000. In the case of replacing the solar panels, the cost will be affected by the following factors:

  • The number of solar panels
  • The type of solar panel
  • Rooftop evaluation and ease of installation
  • Household electrical demand
  • Solar panel mounting hardware
  • Solar inverter
  • Labor

Are Solar Inverters Covered By Insurance?

While most homeowner insurance policies cover solar inverters, not all damages will be covered. If the solar system incurs an electrical breakdown (improper wiring or testing, wrong installation) or mechanical breakdown (poor maintenance, weathering), it will be excluded from the policy. This is why a separate policy might be needed in order to cover the losses or damages.

To make sure your solar inverter is covered by insurance, check your current policy and determine whether you need a separate policy or if you only need to increase the amount of your coverage.

How Much Does It Cost To Install An Inverter?

Solar panels cannot function if there is no inverter. Depending on the size of the solar installation (in watts), the installation of an inverter usually has an average cost of $1000 to $1500. You can actually compute the installation of an inverter by multiplying the installation size by the average inverter cost. This way, you could identify whether you are being overcharged or undercharged by a solar installer.

How Much Does It Cost To Install An Inverter?

Solar inverters have shorter lifespans than solar panels since they have electrical components that are more sensitive to heat and more prone to damage and failure. Strong solar inverters usually last for 10 to 15 years while some microinverters and DC optimizers have longer lifespans, lasting 20 to 25 years.

The life expectancy of a solar inverter depends on many factors such as:

  • Heat and humidity
  • Maintenance
  • Solar inverter manufacturer
  • Grade of its electrical components
