High failure rate for micro-inverters
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.

Great Panels - Oklahoma
The ET Solar 250 watt panels have been working great for about the past year. Have 15 installed with 12 more going in right now. On colder winter days with bright sun the 15 panels were producing over 98% of their theoretical Max even with the low solar angle near the winter solstice.

We Love IT
We have been using ET Solar just recently. We love quality of product and customer service they offer on DC and AC modules. We enjoy the quality they have to offer and has a great warranty. We love the AC modules(SoalrBridge Partner) and predominantly use them. With our installed capacity of over 180Mw of renewable energy we feel that we have a good idea on what makes a good product. The technical support is knowledgeable and responsive and great sales model. Purchasing is smooth and sales rep interaction is good with excellent volume of product available. Their continued effort for product improvements certainly show. ET Solar is certainly on track to become our number one module line up. We use or would recommend and continue to use them in the future is for certain.
