## FAQs

**How do you size a solar panel fuse?** The size of a solar panel fuse is determined by the current that the solar panel can produce safely. It’s important to choose a fuse that can handle the maximum current generated by the solar panel without blowing prematurely. To size a solar panel fuse, follow these steps:

- Determine the short-circuit current (Isc) of the solar panel. This information can be found in the manufacturer’s specifications.
- Choose a fuse rating that is slightly higher than the Isc. This ensures the fuse doesn’t blow during peak current production while providing protection.
