If solar panels are the face of solar power, solar inverters are the heart behind it. Without inverters, you aren''t able to power your home with solar energy, so it''s vital that this important piece of the system is protected
As with solar panels, the available warranties and protections for solar inverters are among the most important factors to consider when comparing your options. However, sifting through pages of dense documentation can be intimidating and confusing, and warranties vary by both manufacturer and product, making direct apples-to-apples comparisons near impossible.
Fortunately, EnergySage has developed a scoring system to help consumers compare. This system considers factors such as product warranty terms, labor and shipping coverage, and how easy it is to transfer ownership.
We''ll review the most important aspects of a solar inverter warranty, discuss what''s standard for the industry, and compare some of the top inverter brands on the EnergySage Marketplace.
Inverter warranties vary by manufacturer and inverter type.
String inverters typically come with 10-12 years of warranty coverage, whereas microinverters and power optimizers are often covered for 25 years.
Labor and shipping expenses are generally not included in solar inverter warranties, but some of the strongest brands will cover one or both of these costs.
Based on our ranking system, Hoymiles, SolarEdge, Tigo, SMA, and Enphase have the strongest warranties.
Inverters are the unsung heroes of solar energy systems. Without them, you wouldn''t be able to harness the power of your solar panels to power your home. Solar panels generate direct current (DC) electricity, but most home appliances require alternating current (AC) electricity. Inverters take the DC electricity from your solar panels and convert it to AC electricity usable for your home.
A solar panel system is a multi-decade investment that is paid off over years through reduced utility bills, and depending on your location, other benefits for sending excess power back into the grid. The less solar power your system produces, the more your home may need to draw from the utility company, which eats into your savings. A good warranty ensures your solar inverter is free from manufacturing defects over its term, protecting your expected return on investment.
Solar inverter warranties look different from company to company and product to product, so we developed a scoring system for easier comparison. The warranty factors include:
The number of years the warranty covers the integrity of the equipment.
Does the manufacturer''s warranty cover the work needed for diagnostics, repairs, or replacements? Is it up to a certain dollar amount?
Does the warranty cover the cost of sending out any components that must be diagnosed, fixed, or replaced?
How easy is transferring the warranty to the new owner if you sell your house? Is there a transfer fee? Do you have to complete any paperwork, or does it transfer automatically?
Also known as a materials warranty, a solar inverter product warranty covers the integrity of the equipment itself. If your solar inverter has a defect or mechanical issue, if it breaks, or experiences unreasonable wear and tear, that''s where your product warranty comes into play.
Unlike solar panel warranties, inverter product warranties are harder to compare apples-to-apples. For starters, there are three different types of inverters, all of which are subject to varying industry standards; most string inverter technologies come with a warranty of about 10-12 years, while microinverters and power optimizers often have 25-year warranties. If you install a string inverter with power optimizers, your string inverter and power optimizers will likely have different warranty terms.
While the warranty terms for inverters themselves vary, warranties for communications equipment (which allow the inverter to connect to other devices like solar panels and battery systems) are typically capped at 5 years for both string inverters and microinverters.
With all this in mind, we created a ranking system that weighs inverter technology and warranty term length to better compare your options across different inverter technologies. However, the best inverter for you largely depends on your system''s unique needs: A 25-year microinverter warranty may rank higher than a 12-year string inverter warranty, but the string inverter may be better suited for your system and, therefore, more valuable to your investment.
It''s unlikely, but let''s say your solar inverter fails after nine years. Things happen. By then, your manufacturer will probably have a new generation of inverters in stock. Will the manufacturer still be able to replace your broken inverter?
