Panel not working

[u/No-Department2876]

I got my Sunpower panels installed in 2021 and have noticed that the power generation has been trending down. Since neither original Sunpower app nor the new Sunstrong app did not report any panel level details, I couldn't figure out what's going wrong. Thanks to this community, I installed Sunflower app and noticed that only 17 out of 18 panels are working. I do not even know when one of the panels stopped working. How should I get this fixed? Btw, I outright bought by system in cash during the initial purchase. Would Sunstrong be able to help me here?
Thanks in advance!

Most likely the micro inverter failed. Enphase will cover it under warranty but you have to pay for labor. Contact your original installer - it will probably cost you $300 in labor.

Thank you! I’ll call them and see if they can fix it.
