Comparison
Plug-In Solar vs Rooftop Solar
Two very different scales of solar. One is a small daytime offset; the other is a long-term home investment.
Plug-In Solar
Small kits (300–1,200W) that feed a circuit via a microinverter.
Best for: Curious beginners, renters, small offsets
Watch out: Utility approval and code compliance vary by state.
Rooftop Solar
Professionally installed, permitted, multi-kilowatt PV system.
Best for: Homeowners wanting major bill offset
Watch out: High upfront cost and long contracts.
