46kW rooftop solar and 25kWh battery system, Newcastle city centre

The job

The building has a large flat roof, shared with existing air conditioning plant, in the middle of Newcastle. We designed the array to fill the usable roof space around the plant, fitting 101 x 455W panels for a system of around 46kW.

A Solax hybrid inverter runs the system, paired with a 25.2kWh Solax Triple Power battery stack. The battery stores surplus solar generation so the building can use more of its own power, rather than exporting it and buying electricity back later.

No holes in the roof

Drilling through a flat roof's waterproofing creates a risk of leaks, so we used a Van der Valk ballasted mounting system. The frames sit on the roof surface and are held in place by weight, with protection pads underneath to look after the roof membrane. The layout and ballast were planned to suit the roof and the building's exposure to wind.

Working on a city-centre roof

With the building in the heart of the city, getting materials up was a project in itself. Panels, rails and ballast were craned up onto the roof in pallets, and the roof edges were protected with scaffold edge protection throughout the install so our team could work safely.

Commercial solar from Hasmart

We design and install commercial solar and battery systems for offices, industrial units, farms and public buildings across the North East, on flat roofs, pitched roofs and ground mounts. Call us on 0191 519 7322 to talk about your building.
