Plug-in solar makes a modest contribution from a suitable small space. Rooftop solar can meet a larger share of demand and support a designed battery system, with a larger budget and more permanent work.
A small system for a specific opportunity
A permitted sunny balcony, garden or terrace may make sense when full rooftop solar is impractical. The 800W output ceiling limits what it can contribute at once.
It can reduce daytime imports. It is unlikely to meet a large household’s heating, cooking and EV charging ambitions.
When rooftop solar deserves a quote
A substantial usable roof, significant electricity use and plans to remain in the property can make a professionally designed installation worth comparing. The design can consider multiple roof directions and the whole electrical system.
If evening use, batteries or backup matter, ask for them to be designed in. The 2026 solar-only plug-in route does not cover a battery-equipped device.
