Vale households are being encouraged to invest in renewable energy sources through a group-buying scheme.
Solar Together, which has already been run in England, is running its first Welsh scheme in the South East.
Vale of Glamorgan Council is one of seven local authorities in the region working alongside iChoosr, which runs the Solar Together scheme and specialises in sustainable energy transition.
It aims to help homeowners feel confident about paying the right price for a high quality installation from qualified installers.
Cllr Bronwen Brooks, cabinet member of sustainable places, said: "The Vale of Glamorgan Council is committed to protecting the natural environment and investing in renewable energy."
"That is a fundamental part of our Project Zero efforts to become a carbon neutral organisation by 2030 and a net zero carbon county by 2050."
"This scheme offers residents the chance to help the planet, reduce their energy bills and get the very best price on solar panel installation through its innovative business model."
It's free for households to register to the scheme with no obligation to go ahead with an installation.
Solar panels with optional battery storage and EV charge points are available, along with retrofit battery storage for residents who have already invested in solar panels and are looking to get more from the renewable energy they generate.
The scheme is also available to households in Cardiff, Caerphilly, Newport, Blaenau Gwent, Torfaen and Monmouthshire.
Marie-Louise Abretti, Solar Together's UK business manager, said: "With energy prices continuing to fluctuate, residents of South East Wales are looking for opportunities to reduce their carbon emissions, save on energy bills, and increase their independence from the grid."
"The Solar Together group-buying scheme offers a straightforward way to make an informed decision and to access a competitive offer from a trusted, vetted provider."
iChoosr has been running the Solar Together scheme alongside UK councils since 2015.
Over 200 schemes have been run in five countries, leading to over 191,000 households installing solar PV or battery storage systems through group buying.
Approved solar PV suppliers take part in a reverse auction where they able to offer competitive pricing as the volume and geographic concentration makes it possible for them to realise greater efficiencies, which they pass on with lower prices for installations.
After the auction, registered households are sent a personal recommendation by email which is specific to the details they submitted in their registration.
If they choose to accept their recommendation, the specifics of their installation will be confirmed with a technical survey after which a date can be set for the installation of their solar PV system.
Telephone and email help desks are on-hand throughout the whole process which, together with information sessions, will allow households to make an informed decision in a safe and hassle-free environment.
Cllr Dan De'Ath, cabinet member for climate change at Cardiff Council, added: "Installing solar panels could potentially save homeowners money on their energy bills as well as helping Cardiff achieve its carbon neutral ambitions, but the idea can seem daunting."
"By bringing the Solar Together scheme to South East Wales, we hope to replicate the success the scheme has already had in other areas of the UK, in encouraging and supporting people to make the leap to a cleaner, greener future."
