Good quality cell's, specifications seems accurate as it outputs the advertised 5A in full sun. DC output is not regulated and it exceeds the advertised 18V, no load output voltage is 22V so be careful if you want to power something from the DC output to be able to handle the 22V. I wanted to power a battery charger which can't take more than 18V so I added a voltage regulator (Buck converter) to the DC output in order to limit the no load output voltage down to 18V. The velcro band form the pocket came loos from the stitching only after 3 or 4 openings but it's not a big issue it can be glued back, so I give it only 4 stars.

Προτείνω το προϊόν, δίνει σταθερή παραγωγή. Κατά τη διάρκεια της ηλιόλουστης μέρας του Νοεμβρίου δίνει 78 W 19,6V έξοδο. Όταν τα σύννεφα καλύπτουν τον ήλιο, η έξοδος πέφτει στα 20w. Αυτές οι μετρήσεις έγιναν όταν το πάνελ κρεμόταν νότια στο μπαλκόνι, οπότε το πάνελ δεν ήταν 100% κάθετο προς τον ήλιο. Μου αρέσουν πολύ οι προσαρμογείς και η ποιότητα του πίνακα. Ευχαριστώ για το προϊόν.

I recommend the product, It gives stable output. During sunny November polish day it gives 78 W 19.6V output. When clouds cover the sun, the output drops to 20w. That measurements were taken when panel was hanging to the south on the balcony railing, so the panel was not set 100% perpendicular to the sun. I really like the attached adapters and the quality of the panel. Thank you for the product.
