We had our solar panels installed by Longhorn Solar. They completed the job on Christmas Eve, 24 Dec 2013. I was very excited about getting the system installed and seeing what it could do. Four and a half years later: As of 16 Aug 2018, 30 out of the original 42 micro-inverters had been replaced. This is 30 out of the original 42 in 56 months or a failure rate of one micro-inverter about every two months. The latest problem: I reported a panel problem on 16 Apr 2019, and assuming it was a micro-inverter problem, Longhorn Solar ordered a new micro-inverter. The company that makes these things takes about two weeks to deliver. Sure enough, on 30 Apr 2019, Longhorn came out and installed the new converter. Longhorn Solar apparently can not keep a replacement micro-inverter in their warehouse. They did it in the past, but no more. I talked to a representative from Longhorn Solar today, and they admit that they know the micro-inverters that were installed with my solar system have a high failure rate. The company they get micro-inverter from admits that the micro-inverters have a high failure rate. I keep reporting failures and weeks later, I get another replacement. I can only figure that this will keep happening until my warranty runs out, then gradually each of the 42 micro-inverters will fail and the whole system on my roof will be so much garbage. Other issues: Longhorn Solar admits that they only check their service email account once a week. WTF? Longhorn Solar used to be able to look at my system via an Internet connection, but the monitoring software changed. Now, it is up to me to check it. I try to check up on it every couple of days, because if I don't discover the problems, no one ever will. The software to monitor the panels no longer has a way to see the history of a panel. I have to check the system during the day while the sun is out, because at night, I can no longer go back to check the history. Good luck on monitoring the system if you work for a living.
