Shared Solar for Apartments

Allume SolShare: one rooftop, shared fairly

Allume SolShare is the shared solar technology we install for apartment and unit blocks — a single rooftop solar system, shared live across every apartment's own meter.

How SolShare works

Divides, shares, saves

SolShare is smart hardware fitted between the solar inverter and the building's main switchboard. It divides the solar system's output and shares it fairly across every connected apartment's own meter, on the load side — no change to existing meter infrastructure, and no access needed to individual apartments.

  • One SolShare unit connects up to around 15 apartments (larger buildings can install multiple units)
  • A dynamic sharing algorithm balances each apartment's allocation in real time, then evens it out over the month
  • Typical solar allocation per apartment: roughly 1kW–5kW, depending on building size
  • Works with any brand of solar panel and inverter, no batteries needed
  • All installation work happens in common areas (roof, switchboard room) — no apartment access needed
  • 10-year manufacturer's warranty on the SolShare unit
NSW Solar for Apartments

Support for eligible strata buildings

The NSW Government has run a Solar for Apartments grant to help strata buildings with the cost of shared solar like SolShare. Programs and eligibility change, so we'll check what's currently available for your building when we come out, and we look after the strata approval process with your owners corporation.

Why Allume SolShare

Why we use SolShare

Divides

SolShare splits the energy from a single rooftop solar system — smart hardware that works with any panel, inverter or battery brand.

Shares

A dynamic sharing algorithm allocates energy fairly across every connected apartment and common area, balancing usage over the month.

Saves

Households use more of the solar generated on their own roof instead of it being exported to the grid for a low feed-in rate.

SolShare is Australian-designed technology, developed by Allume Energy and installed across strata and apartment buildings nationally. We don't put prices online. Every job is quoted in person, on site.
