A microinverter is a small electronic device that sits beneath each solar panel. It’s main task is to convert direct current (DC) from your solar panels into alternating current (AC) electricity that you can use in your home or export to the grid.

With our Maxeon solar panels we offer the longest warrany in the industry: 40 years. And that covers both the product and the performance, which is not the case for all the other standard panel warranties. That’s because we know that our technology is designed to last even more than 40 years. Our Performance value line are backed by a 25-year Warranty. . Regular maintenance, environmental conditions, usage patterns, and technological advancements can influence their lifespan.

With a string inverter there is a single point of failure. If the string inverter fails, the entire array is offline. However, with a microinverter each individual PV module has its own dedicated inverter. If the microinverter (or the associated PV module) should fail. only that PV module is offline while the remainder of the system continues to operate.​ Enphase microinverters have a publicly stated defect rate of 0.05%, which equates to 1 in 2000. Given that the Enphase defect rate is better than most string inverters, this results in a PV installation with higher reliability and a higher overall system uptime over the life of the array.

Additionally, Enphase microinverters have an estimated useful life of more than 25 years, compared with string inverters that typically last around 10 years.

If the microinverter (or the associated PV module) should fail, only that PV module is offline. The remainder of the system continues to operate as normal – a key benefit of AC modules.​

All AC module installations must be Internet connected for the monitoring to receive the 25-year microinverter warranty. This Internet connection reports data to the Enphase monitoring platform, Enlighten on a per microinverter/module basis. The performance of each microinverter and module is visible to the installer via Enlighten and alerts are provided for any faulty equipment, such as an under-performing PV module or a faulty microinverter.

A SunPower Maxeon solar panel can provide up to 85% more energy over its lifetime1 Power output varies by installation and location. Please consult your installer partner about expected output for the life of your system.  compared to other panels. It has a strong power output advantage from day one and maintains that power advantage over time with a .2% annual degradation rate. With its industry-leading 40-year warranty, this panel will grow in value over time.
