For crystalline panels, you can expect 1 amp output for every 15 watts of panel in ideal sun. In optimal sun, it will produce 2.33 amp hours. While it is less, the panels do not have a rated output in cloudy conditions. Amorphous panels will produce slightly more power in low light and will even work with artificial light. The crystalline panels will produce more in sunlight which, if used permanently outdoors, is most always going to offset the less power made in lower light conditions. On average, amorphous panels will produce 1 amp for every 17.1 watts of panel.
