Parameters as described. Panel short circuit current in full sun 4,4 (up to 4,9A) depends on angle to the sun. Panel as described is >80W peak. Regulator works well. Please note that while panel is really 80W@18V, useful power @12V is lower - about 60W. To know what size of panel You need it is better to look at Amperes.
