How apartment buildings can finally share solar and battery

Before SolShare: One solar PV system and battery could only power one electricity meter.
The challenge: Solar and stored energy were limited to communal areas or required separate systems for every flat.
With SolShare: One rooftop solar system and communal battery can power multiple individually metered flats.
The result: More residents benefit from clean, affordable solar and battery energy. 

What is SolShare?

Allume's SolShare is the world’s first technology that connects multiple flats to one rooftop solar PV and battery system. It makes shared solar simple by removing the need for separate solar systems for every apartment, making solar more practical and commercially viable for buildings.

How SolShare works

Improves SAP and EPC performance

SolShare allows solar generation to be allocated between flats, helping developments meet SAP requirements and improve energy performance. It can increase SAP scores by up to 20 points.

How SolShare works

Works seamlessly with batteries

SolShare integrates with battery systems to store excess solar energy and share it across flats when residents need it most. By intelligently managing solar and stored energy, it helps residents use more renewable power and  reduce bills by up to 70%. 

How SolShare works

Maximises solar self-consumption

Instead of exporting unused solar energy to the grid, SolShare intelligently shares power across the building. By increasing self-consumption and reducing reliance on grid electricity, SolShare can help achieve 40% reduction in grid electricity demand.

What is SolShare?

SolShare by Allume is the world’s first solar technology connecting multiple flats to one solar PV system. It’s the smartest way to bring solar panels to buildings. It eliminates the need for individual systems for every flat, making shared solar technically simple and commercially viable.

Boost SAP & EPC ratings

Allocate customised solar PV energy (kWp) to each individual flat. This is a game-changer for developers and asset managers looking to improve EPC ratings across a portfolio. By tailoring energy distribution to meet specific SAP calculation requirements, Allume helps high-density buildings reach modern sustainability standards.

Maximise savings for residents

By sharing energy intelligently and dynamically, SolShare ensures that more free, solar electricity is used within the building rather than being exported to the grid. This maximises self-consumption, leading to significantly lower energy bills for residents and a superior return on investment (ROI) for apartment solar projects.

Testimonials

“Many of our tenants at Scott Court have already reported noticeable savings on their energy costs, with some saying they’re topping up their pre-payment meters far less frequently. This is a real and tangible step forward in our mission to tackle fuel poverty."

"We installed just 3 inverters with 3 SolShares to serve 35 properties. If it wasn’t for Allume, we couldn’t have done it, there simply wasn’t space to fit 35 inverters."

“Scott Court is more than just a retrofit; it’s a blueprint for the future of socially responsible, sustainable housing.”

David Conway, Head of Asset Management, Hillcrest, Scotland

“Because the system shares free solar energy across the whole building, everyone saves more on bills than if we just had lots of individual little solar systems on the roof, each feeding one flat each.”
