Introduction

In late 2025, we were appointed to design and install a solar PV solution for Ysgol Awel Y Mynydd, a modern primary school located in Llandudno Junction, Conwy. The project formed part of the school’s wider sustainability strategy and supported Conwy Council’s commitment to reducing carbon emissions across its schools. The challenge was to design and install a high performing solar energy system that complemented the building’s strong environmental credentials while delivering long term energy savings for the school.

Opened in 2017 as part of the 21st Century Schools Initiative, Ysgol Awel Y Mynydd replaced two older primary schools and now accommodates up to 420 pupils. The building already benefits from a BREEAM Excellent rating with passive solar gain, natural ventilation and a large wildflower roof. Our task was to integrate a rooftop solar PV system that enhanced these features without compromising the building’s design or daily operation.

Methodology

Our team began with a detailed site assessment to evaluate roof orientation, structural integrity and electrical capacity. The metal roof was surveyed to confirm it could safely support a photovoltaic installation. Fortunately, the roof pitch faced predominantly south east, making it well suited for efficient solar generation in North Wales.

Using this data, we designed a bespoke solar PV system consisting of five separate arrays. In total, 112 high efficiency panels were specified, each rated at 445 watts, providing a combined system capacity of 49.84 kilowatts. Careful planning ensured optimal panel spacing, orientation and connection to the school’s existing electrical infrastructure. A clear installation schedule was agreed to minimise disruption and maintain a safe environment.

Installation

The installation was carried out outside school hours to ensure pupil safety and avoid disruption to teaching. High quality Trina solar panels were mounted using a robust Van der Valk mounting system, chosen for its durability and suitability for metal roofs.

Each array was securely fixed to mounting rails and professionally wired into the school’s electrical system. Once installation was complete, the entire system underwent comprehensive testing and commissioning to confirm performance, safety and compliance with industry standards.

Outcome

The completed 50kW solar PV installation is expected to generate approximately 50.23 megawatt hours of renewable electricity each year. This will significantly offset the school’s energy consumption and reduce reliance on power from the National Grid.

Environmentally, the system is expected to save approximately 9.71 tonnes of carbon dioxide annually, equivalent to planting approximately 446 trees each year. Financially, the school can expect energy cost savings of around £12,557 per year, along with greater protection from future energy price rises.
