Flexible solar panels are less efficient than rigid panels but have a wider variety of applications due to their flexibility and thin size (typically 200 micrometers). Recently, organic silicon cells have been used to make flexible solar panels.

Flexible panels cannot use glass, obviously, but polymers. Transparent polymeric films have been always thought as a glass replacement, they are lighter and unbreakable but, whatever the chemical choice, polymers cannot be compared to glass when decades of outdoor.

Those three sentences cover every solar wiring decision you will ever make. Series: connect positive (+) to negative (−) between panels — voltages add, current stays the same.

The required panel watts = 1280Wh ÷ 10h = 128W Also, consider the charging efficiency of your solar system, which depends on both the battery chemistry and the type of solar charge controller used.
