Kanthal - Fully-funded rooftop solar

Two Blues Solar partnered with Biosus Energy, a renewable energy installation specialist in Scotland, to deliver a 714 kWp rooftop solar PV system at Kanthal's manufacturing site on the Inveralmond Industrial Estate in Perth. The system comprises 1,552 modules across multiple roofs, supported by five 100 kW Solis inverters and one 25 kW unit.

The project is delivered through a 15-year Power Purchase Agreement, giving Kanthal low-cost renewable electricity with zero upfront capital investment — preserving capital for the multi-million-pound facility expansion while securing long-term energy price stability. Two Blues Solar oversaw the entire process, including site feasibility, grid applications, and the legal framework under Scottish law.

The system is designed to achieve approximately 99% self-consumption against site demand of 6.68 GWh per year, and is expected to offset around 8% of total annual energy use. A 200 kVA export limit at the site meant the array had to co-exist with Kanthal's existing 500 kW CHP, which has been reconfigured to curtail first whenever generation approaches the export cap — ensuring solar takes priority and grid export is kept to a minimum.

The system was specifically engineered to support the energy-intensive nature of Kanthal's 24/7 manufacturing operations and to co-exist with its active CHP unit. With a live industrial site and a tight pre-spring 2026 deadline, the delivery had to be as carefully managed as the engineering.

Two Blues Solar oversaw the entire process — site feasibility, grid applications, and the Scottish-law legal framework — before bringing Biosus Energy on board to deliver the installation. From there, the focus shifted to running a 10-week build with zero disruption to production.

That started with detailed negotiation at the front end to understand every operational requirement before any equipment arrived on site. A dedicated base of operations was allocated within the facility, equipment deliveries were coordinated to slot in around Kanthal's own inbound and outbound product flows, and scaffolding works were scheduled exclusively at weekends so that weekday production was never affected. A permanent on-site resource was assigned for daily coordination with Kanthal's site manager, giving the client a single point of contact and clear visibility into the build at every stage.
