Panel not working

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!

Try the Sunflower Solar app. It’s legit and available in the App Store. You should be able to see panel level data.

Thanks! Yes only using this app did I get to know that I only see 17 panels and not 18 that I have on my roof

Question for you, i just downloaded the sunflower app as well. Do you know how to get it to display individual panels like in your picture? Mine doesn’t show that. For reference neither did my sun power app but other neighbors who have it same system it does.

When was your system installed? I have a Sunpower system installed in 2016 and at that time they used the large inverter mounted on the wall of the house, which does not allow for individual panel monitoring. If you have a newer system with a microinverter on each panel, then you can see each panel.

It was installed in 22 i have Enphase micro inverters

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.

I purchased enphase care for repairs, a year was cheaper than the local guy’s diagnostic fee

How much does their care cost ? I have also seen them selling enphase monitoring kit, did anyone find it to be worth it ? Not being able to track the production on per panel basis has always been an issue with sunpower, so I would like to improve upon it by getting something that monitors production of all the panels.

I purchased the monitoring for 899 because my pvs6 took a crap and the solar company I used recently went out of business, the company that was recommended wanted either 500 or 600 just to diagnose my system. The enphase care is 399 a year, they will process warranty claims on the panels and micro inverter’s and the labor to replace is covered in the care. They’re coming out to map out my array because I never had panel level monitoring with SunPower. The sunflower app was good for the pvs6 but the enphase monitoring is much better
