Can Solar Panels Work Without Diodes?
Increased Risk of Damage. Solar panels without diodes are at a much greater risk of damage from reverse currents and hotspots. Reverse currents occur when an individual solar cell generates less voltage than the rest of the cells in a panel. This causes current to flow backwards through that cell, which can overheat and degrade it.
