Hey @rtbarry! Having the solar status appear in your Ring app device health is a great sign that there is still a charge coming from it and being registered. Although this is indicating there is not enough sunlight, this message should not last long especially in the direct sun as your picture shows.
While the message mentions sunlight, other factors might be impacting the Solar Charger such as temperature, wifi signal interference, number of daily events, number/ length of live views, and even any debris on the Solar Charger panels. Of course, temperature can be ruled out if it is 90 degrees. Check out our Community post about battery drain for tips on optimizing solar charging, then monitor battery and solar status for improvements. I hope this helps!
