Some objects fit easily into a faraday box or can and others don’t. This is true of a solar panel that is too big for a container crafted to protect small electronic devices. The charge controller and inverter easily fit into a smaller container, but the panel is flat and larger by comparison.
[NOTE - what will be or won't be affected by an EMP is a fair matter of contention. We have little confirmed knowledge in this area and most hard data from military testing remains classified. Some say solar panels will be fried, others maintain they won't be affected at all. At least one component of most solar panels is a diode and they are likely to be susceptible to EMP. The charge controller and inverter are highly likely to be damaged.]
Here is a description of a faraday “blanket” that can be used to protect odd shaped objects. Basic requirements were: cheap, practical, easy to make, possible to re-use without needing replacement materials.
- 50″ x 50″ piece of an old plastic drop sheet (6 mil thick?)
- roll of aluminum foil
- roll of duct tape
- roll of press n’stick plastic wrap
(like Saran wrap that clings to itself)
- Duct tape panels of aluminum foil onto the plastic sheet.
- Line the foil with press n’stick wrap (to insulate).
- Place the solar panel on top.
- Fold the wrapping over the panel and duct tape it closed.
