Connecting solar PV to submeter?

[neilf]

Hi,

Is it possible to connect solar panels to a sub-meter, or does it have to be connected to the main meter?

Context is non-residential building with two separate tenants. The tenant on submeter is looking to install solar PV to cover their electricity requirements.

If the tenant is paying for the solar PV then it MUST be connected downstream of their sub meter or they won't get the benefit of the PV (it would not reduce their metered use)

To expand on ProDave's reply:

The tenant should have their own sub "fuse box" (Consumer Unit) that has all their circuits in it, and is fed by a single cable from the building's supply.
Then the meter can either go in-between the inverter and its "fuse" in that CU.
So that it measures the generated solar, if the tenant is getting a payment, a tariff, for that.
Or in the cable between the CU and the single cable from the building's supply.
So that their actual reduced useage from the electricity supply, due to the solar generation, can be supplied to whoever they pay their bill to.
Or both !
