I am a consumer and producer of electricity
I utilise electricity generated and supplied to the National Grid, via connections provided by power companies and my house builder.
My solar PV system was installed (and is maintained when necessary) by a local builder with components from China, Germany and probably many other countries.
My solar panels harness energy, that my inverter turns into electricity, which I can use or supply to the National Grid, in return for a tariff provided by the UK Government via a French Power company
