Solar Inverter Comparison Chart

Note: the chart that used to be on this page has been decommissioned – see our shiny new inverter comparison table here.

When comparing inverters, the most important consideration is reliability.  Good quality solar panels can be expected to last well over 30 years, so you’ll also want an inverter that will operate problem free for a long time.  While inverters don’t last as long as panels, they can last a long time. My friend had a German inverter installed in 2003, and it’s still going strong. 

Inverter efficiency is another consideration, but much less important than in the past. These days, there’s little difference between modern inverter efficiencies, and a cheaply made inverter can be very efficient without being reliable. 

To get the details on currently available inverters, check out our new inverter comparison table here.

One of the best ways to judge a product’s reliability is to check out our solar inverter reviews, where I’ve asked thousands of solar system owners who’ve had their system for more than 12 months how reliable theirs has been.
