Hill Grwp Ltd recently completed the design, manufacture, delivery and installation of a bespoke GRP substation enclosure for a solar farm project, built around the practical requirements of the equipment, site layout and access strategy.

Solar farms rely on much more than solar panels. Behind the visible array, there are systems that collect, control, transform and transfer electrical power. Depending on the project, this infrastructure can include switchgear, transformers, metering equipment, control equipment, cabling and connection systems. Solar farm substations are commonly used to support this process, with electrical infrastructure playing a key role in connecting generated power to the wider netwo

Back to work and full of new energy as projects continue to move from production to site.

Choosing the right GRP (Glass Reinforced Plastic) enclosure is essential for protecting valuable equipment, maintaining site safety, and ensuring long-term reliability in demanding industrial environments. While many GRP manufacturers produce good-quality composite enclosures, very few are able to integrate fully engineered steel doors into their GRP buildings.

From design → manufacture → logistics, our team handled every detail to ensure safe delivery and smooth installation on site. - Heavy-duty industrial equipment - Harsh outdoor environments - Compliance and long-term access needs

At Hill Grwp, we design and deliver fully integrated electrical layouts, tailored to your exact specifications. Inside each substation, you’ll find pre-installed switchgear, transformers, control panels, and protection systems, all factory-tested for smooth, fast commissioning.

We recently designed, manufactured, and delivered a bespoke GRP substation with a C5 Corrosion Resistant painted steel base. Engineered for durability, safety, and operational efficiency, this unit demonstrates our capability to combine GRP technology with structural steel elements to meet complex site requirements.
