Works in theory! Practice? That's something else
A lot of panel warranties are voided by being improperly installed - no surprise... except that by improper they include excessive shading. The bypass diode's purpose is to prevent damage caused by shading. But, the current flowing through the diode shortens the diode's life, and if it fails the heat buildup can kill the panel.

From the LG warranty:
Improper installation or reinstallation and poor solar system design. (Examples of improper installations and very poor system design are modules installed in conditions which put long term stress on the bypass diodes in the modules, and also reduce the system output for the owner – for example prolonged significant strong shadowing of the modules e.g. via trees, walls, gables, overhangs, valleys, chimneys, satellite dishes etc (In such situations a professional solar designer will suggest a micro-inverter or optimiser solution and with such a proper solar system design solution the module warranty is fully applicable).
