Excess Solar generation - not grid connected (G-59)

Aneysha Minocha over 4 years ago

Hi All,

We are working with commercial premises that installed Solar PV in the days of the Feed-in-Tarriff. These sites have excess solar generation being measured through a channel, but there is no export from site (not G-59 connected) and the customer is on a deemed Feed-in-Tariff. From the data, there seems to be a high proportion of "excess" / "export" energy from sites.

Question - if the sites are not consuming the excess energy and thet are not set up for grid export - where is this excess energy going?

Would appreciate your valuable input please.

Thank you!

Thank you All for your responses.

So to summarise, it seems like the inverters are operating in "Open Loop" mode as the sites are generating excess solar which is not used by the buildings' energy demand. Also the excess solar is being measured through an "export channel" as the buildings do not have a G-59 connection in place.

So, does this excess solar still end up being exported into the grid?

Thank you!
