7 Conclusion

If PV panels or solar equipment connected in a series are broen or faulty, it is important to have a design in place to avoid hot spotting and/or voltage supply interruption. This responsibility commonly lies with the solar power optimizer or rapid shutdown. While standard rectifier diodes or Schottky diodes are the simplest solution to bypass the broken panel, they aren’t preferred given thermal inefficiency. A floating-gate ideal diode controller along with an N-channel MOSFET offers less stand-alone loss than a bypass switch solution, and an additional system workaround with a depletion MOSFET offers a completely scalable solution to address the wide input voltage range of PV panels.
