Castle Eco Solutions is Now a SolShare Approved Installer
We are thrilled to announce a significant expansion of our renewable energy offerings! Castle Eco Solutions is now an Approved Installer for SolShare by Allume Energy. This innovative technology is a game-changer, allowing multi-tenant buildings to finally unlock the full potential of rooftop solar.
This approval reinforces our commitment to bringing cutting-edge, sustainable solutions to our commercial clients, helping them achieve significant energy savings, enhance property value, and reduce their carbon footprint.

What is SolShare and Why Is It a Game-Changer?
Historically, installing rooftop solar on buildings with multiple tenancies, like office blocks, retail units, or even mixed-use developments, has been complex. The challenge lay in how to fairly and efficiently distribute the generated solar power to individual businesses or units within that building.
SolShare is a revolutionary technology that solves this problem. It's a patented hardware solution that sits on your building's rooftop, intelligently and dynamically sharing the solar power generated by a single solar PV system among multiple units.
Imagine this: One set of solar panels on your building, but each tenant receives a share of that clean, green energy directly to their individual meter, reducing their electricity bills. This dynamic distribution means everyone benefits, maximising the overall usage of the solar power and ensuring fairness.
