In terms of policy, there are typically three or four aspects that policies for plug-in solar cover:

1. Size limits: in most countries with regulations on plug-in solar, specific size limits are introduced between 400W and 1000W.
2. Registration or notification requirement: most countries include a requirement for plug-in solar systems to be registered with the local utility, or building authority. In most cases, a simple online notification suffices. In many cases, a notification to the landlord or building owner is required. Also, local housing associations may have their own policies.
3. Regulations surrounding proper installation, including building codes: in some cases, public authorities provide diagrams describing how systems can be properly installed. This can include, for instance, restrictions around mounting plug-in solar systems above public walkways, or in areas where they could pose a risk to people, or property.

Two additional aspects that are occasionally included in regulatory frameworks include restrictions around the use of solar in historic districts, as well as quality standards. In most cases, plug-in solar systems are required to be in conformity with national electrical code requirements.

With these basic policies and guidelines in place, policymakers can ensure that the plug-in solar market develops safely, and in line with national regulations.
