If your state has not enacted a plug-in solar law, you may still be able to use solar—but the legal, technical, and safety answer starts with a critical distinction: whether the system stays independent of utility wiring or operates in parallel with it.
In this Plug-In Solar Deep Dive episode, Lisa and Mike separate three commonly confused paths: truly off-grid systems for non-utility-served structures; portable/standalone solar and power stations for devices plugged directly into the power station; and zero-export systems connected to a utility-served home. They explain why zero export is not the same as off-grid, why utility interconnection may still apply, and why local permits, property rules, and electrical safety matter even when no utility connection is involved.
The practical takeaway is straightforward: choose the simplest safe configuration that meets your need. Treat a portable power station as a standalone power source, treat permanent installations as code-and-permit questions, and contact the utility before connecting any generating or storage system in parallel with utility-supplied wiring.

Key Takeaways
- The electrical boundary matters most. Truly off-grid and portable standalone systems do not run in parallel with utility wiring, whereas zero-export systems do.
- Off-grid does not mean code-free. Permanent PV and battery installations can still involve local permits, inspections, property approval, and safety requirements.
- Zero-export is not a universal exemption. A system operating in parallel with the grid may still require a utility interconnection process, even when it is designed not to export energy.
