Now, lets see how can we protect a solar panel or photovoltaic array and strings from partial of fully shaded PV cell effects. That is a Bypass diode. Bypass diodes can be used by connecting them in parallel with the PV cell of a series connected string array to eliminate the risk factor and protect the solar panels from overall damage and .
Type 1 SPDs for use in PV systems can be connected between the PV array and the main service disconnect. Type 2: Permanently connected SPDs intended for installation on the load side of the service equipment overcurrent device; including SPDs located at the branch panel and molded case SPDs.
PV systems, as with all electrical power systems, must have appropriate overcurrent protection for equipment and conductors. Globally there is a push for utilizing higher voltages (trending to 1000Vdc and above) to achieve more efficiency. This will mean an even greater need for circuit protection in the future.

6 FAQs about [How to add load protection to photovoltaic panels]
Do I need a surge protection module for a solar inverter?
It is compulsory to install SPD (surge protection devices) at the ac output of a single phase and three-phase solar inverters. The surge protection module will protect the inverter from high voltages that might be detrimental for the MOSFET and IGBT (internal semiconductors). We recommend the following devices with din-rail mounting.
Do PV systems need overcurrent protection?
PV systems, as with all electrical power systems, must have appropriate overcurrent protection for equipment and conductors. Globally there is a push for utilizing higher voltages (trending to 1000Vdc and above) to achieve more efficiency. This will mean an even greater need for circuit protection in the future.
How do I protect my solar power system from lightning?
Lightning is a major cause of surges especially in areas prone to storms. So, to protect your solar power system, consider adding an extra layer of protection. They’re a form of heavy-duty surge protectors. They can handle the massive power of a lightning bolt and safely divert it to the ground.
What is a good voltage protection level for a solar array?
To have a protective effect, an SPD’s voltage protection level (Up) should be 20 % lower than the dielectric strength of the system’s terminal equipment. It is important to use an SPD with a short circuit withstand current greater than the short circuit current of the solar array string that the SPD is connected to.
Where to install surge protectors in a solar power system?
Where to Install Surge Protectors in a Solar Power System: A Comprehensive Guide - Solar Panel Installation, Mounting, Settings, and Repair. Surge protectors for a solar power system should be installed at two critical points. Firstly, place them on the DC side between the solar panels and the inverter.
Do PV modules need fuse protection?
Fuse protection is required in any PV system that is connected to a battery. It should be remembered that the PV module performance varies with temperature and irradiance level. In operation, PV OCPDs are influenced by ambient temperature and derating should be factored in when being specified.
