Introduction

Ruthin Precast Concrete (RPC), located just outside Ruthin in Denbighshire, recently sought to enhance its sustainability efforts by investing in a large-scale renewable energy solution. RPC specialises in producing high-quality precast concrete products, combining premium stone with the finest aggregates and pigments. RPC sought to reduce its environmental footprint through the adoption of renewable energy. We were tasked with designing and installing a bespoke 542kW Solar PV system for their North Wales production facility.

Methodology

The project began with an initial consultation and a thorough assessment of the structural and electrical conditions of RPC’s buildings. After reviewing the site’s energy demands, we designed a tailored renewable energy solution that meets their current and future requirements. Our primary objective was to maximise the available roof space and optimise energy output for the budget.

Our planning phase also focused on the layout of the buildings, ensuring that solar panel installation would maintain structural integrity and waterproofing. Additionally, we incorporated advanced monitoring and inverter technology to ensure the system could be efficiently managed and maintained.

Installation

The installation comprised 1,291 high-efficiency Trina solar panels, with a total capacity of 542kW. The panels were mounted on the metal roofs of RPC’s buildings, with the system split into 13 separate arrays. Eight state-of-the-art Solis inverters were installed to convert the solar energy into usable electricity. Known for their efficiency, stability, and reliability, these inverters are specifically designed for industrial applications and come with real-time performance monitoring.

We paid close attention to the roofing structure during the installation, ensuring that the panels were securely mounted without compromising the buildings’ waterproofing or integrity. The entire process was completed smoothly, on time, and within budget.

Outcome

The solar PV system has transformed RPC’s energy usage, allowing the company to reduce its carbon footprint significantly. The system is estimated to save 85.7 tonnes of CO2 emissions annually, equivalent to planting 3,939 trees annually. Over its lifetime, the system is projected to generate approximately £2.4 million worth of electricity.

The client is extremely satisfied with the outcome. RPC now operates a modern, energy-efficient facility, reducing both environmental impact and operational costs. The installation has not only optimised their energy use but also demonstrated their commitment to sustainability.
