Solar Together 2025: Purchasing scheme for solar panels

The 2025 scheme application period is now open!

Solar Together scheme is available in the Royal Borough to help residents generate their own renewable energy.

The 2025 Solar Together scheme is open for Royal Borough residents to register their interest for solar panels, batteries and EV chargers. This is the fourth year of Solar Together in the Royal Borough and the scheme has helped hundreds of residents generate their own renewable energy, cut their carbon footprint and save money on their energy bills. 

Solar Together, being run in partnership with independent experts iChoosr, is a group purchasing scheme for solar panels helping make the transition to clean energy for residents and businesses as cost-effective and hassle-free as possible.

It’s free to register and there’s no obligation to go ahead with an installation.

Pre-vetted installers bid in a reverse 'auction' to install solar panels. The process should provide residents confidence that they are paying a competitive price for a high-quality installation.

Key Information

The 2025 scheme application period is now open! Registration closes on the Friday 8 August. 

We suggest applications are submitted as soon as possible because the application deadline could close early if the scheme is at risk of oversubscription.

Please apply to this years scheme.

Businesses are also able to participate in the scheme. The business should be the owner of their roof, or have approval of the owner.

The Solar Together scheme also offers optional battery storage and electric vehicle charging points alongside new solar panel installation or for retrofit alongside an existing solar panel installation.

How does it work?

1. Registration: You can register for free and without obligation on the RBWM Solar Together page. To register, you simply provide details about your roof, such as its size and orientation.
2. Auction: An ‘auction’ will be held early July 2025, where the pre-vetted solar installers will submit bids for the work. The more people that register, the better the deal should be for each household. The installer with the most competitive package will win the auction.
3. Personal recommendation: Each applicant will be emailed a personal recommendation based on the registration details. This includes your costs and specifications of your system.
4. You decide: The decision is then yours, whether you want to accept your recommendation. There is no obligation to continue. You will have approximately six weeks to decide and will be invited to an online video meeting with iChoosr, and the installer, to hear more about the scheme and to ask any questions.
5. Installation: If you accept, the winning installer will contact you to survey your roof and set an installation date. All installations are planned to be completed within six months from the date of the acceptance of the last installation offer.
