Choose your kit
Plug-in solar is sold as a complete panel + inverter + cable system, not separate parts — pick the kit that fits your space and budget below.
None of the kits below currently publish an explicit DESNZ Interim Product Specification (v2.0) compliance statement — until one does, treat it as needing a qualified electrician for the connection. See Is it legal? for the full picture.
