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.

There are several financing options for solar installations, including solar loans, solar leases, and Power Purchase Agreements (PPAs).

The amount you can save on energy bills depends on your energy consumption, the number of solar panels you have, and local electricity rates. On average, homeowners can save anywhere from 20% to 70% on their electricity bills with solar panels.

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.​
