12 Volt Solar Panels: Shading, Parallel, Series, Diodes
As far as I''m aware, only one manufacturer ever made panels like that – UniSolar – and their panels were well known as the most shade-tolerant around. This however made them expensive, and in 2012 they unfortunately went out of business. These days most 12Volt panels are fitted with just 2 bypass diodes, with the panel effectively …
