A Welsh Government-backed energy firm has unveiled plans for a new solar energy farm at Lavernock.
Trydan Gwyrdd Cymru (TGC) says the site could generate enough electricity to power around 13,800 homes.
A planning application is expected by the end of next year - but a public consultation has been launched to gauge the views of local residents.
TGC says the solar farm could be generating green electricity by 2028 - with all profits going back to the Welsh Government.
Project manager Mark Roberts said: "We're looking forward to speaking to local residents and building strong relationships within the community."
"Our commitment is to listen carefully, answer questions, and feed what we learn back into the next stage of the design process."
"We're exploring innovative ways to enhance our sites, so they work harmoniously for both local people and the surrounding habitats."

Last year, TGC announced three sites across Wales for its first proposed wind farms as it aims to produce 1 GW of renewable energy capacity by 2040.
The Lavernock ('Larnog') development, which will be on land owned by the Welsh Government, marks its first solar project - with a potential capacity of 35 MW.
A short section of the Wales Coastal Path runs through the site - but the company says it intends to protect the pathway and improve access for walkers.
There are also plans to 'enhance' local wildlife by creating and improving habitats for bees, insects, birds and mammals.
Two drop-in events on the project will be held in January - at Sully Sports & Social Club on Monday 12th January (3-7pm) and at Lower Penarth Community Hall on Saturday 17th January (9.30am - 1pm)
The public consultation runs until Friday 23rd January with a further statutory consultation due to be held in the summer before a planning application is submitted.
