Introduction

We recently completed a solar PV installation for Ysgol Bro Cernyw, a primary school located in the rural village of Llangernyw near Abergele in Conwy, North Wales. The school sought a long-term renewable energy solution to reduce rising electricity costs, lower carbon emissions, and reinforce its commitment to sustainability. As an educational setting with high daytime energy usage, the site was well suited to a solar panel installation designed to deliver both financial and environmental benefits.

Methodology

Our process began with a comprehensive on-site survey carried out by an experienced member of our team. The assessment focused on roof orientation, available roof space, shading risks, structural integrity and access requirements. Energy consumption patterns were also checked to ensure the system design would maximise on site usage of generated electricity.

The survey identified the pitched roof of the main hall as the optimal location, with two separate arrays positioned on either side to maximise solar exposure throughout the day. Based on these findings, we designed a bespoke solar PV system consisting of 72 high-efficiency 445W panels. A Solis three-phase inverter was specified due to its proven reliability and maximum efficiency of 98.7%. A detailed performance and savings report was then produced to outline projected cost savings and environmental impact.

Installation

To avoid disruption to staff and pupils, the installation was scheduled during a period when the school was closed. Our team installed all 72 solar panels using VarioSole+ aluminium mounting rails, chosen for their durability and suitability for larger solar installations.

As the panels were mounted, DC cabling was connected and carefully routed back to the school’s plant room. The system was then integrated with the existing electrical infrastructure using a three phase 100 amp Emlite smart meter. This allows the school to monitor energy usage, maximise self consumption and export surplus electricity back to the National Grid.

Outcome

The completed system delivers a total installed DC capacity of 32.04kW and is expected to generate approximately 28.17 MWh of electricity annually. This equates to estimated annual electricity cost savings of around £7,042, providing excellent long term value for the school.

From an environmental perspective, the system is projected to reduce CO2 emissions by approximately 5.45 tonnes annually, equivalent to planting around 250 trees each year. The project supports the school’s sustainability goals and serves as a practical educational resource for pupils learning about renewable energy.

Overall, the solar PV installation at Ysgol Bro Cernyw demonstrates how schools across North Wales can benefit from clean, reliable solar energy. If you are considering a solar PV installation for your school or commercial building, contact us today or visit our solar page to learn more.
