Introduction
The JM Renewables team recently completed a project to install a solar photovoltaic (PV) system at Ysgol Nant Y Groes, a primary school located in Colwyn Bay on the beautiful North Wales coastline. After a thorough assessment of the site, we designed a system comprising 216 solar PV panels distributed across three rooftops, yielding an impressive total output of 90.72 kW. The rooftops were selected based on their orientation, shading and suitability for mounting solar panels.
Methodology
Our methodology began with a comprehensive site assessment to evaluate the different solar installation options. Key factors such as roof orientation, structural integrity, and shading were carefully analysed. Schools are ideal for solar installations due to their extensive rooftop space, and Ysgol Nant Y Groes provided plenty of options for optimal panel placement. Based on our assessment, we designed a bespoke solar PV system that would maximise energy output. The chosen rooftops were ideal in terms of sunlight exposure and structural support for the panels.
Installation
The installation commenced with mounting the solar panels onto rails on the three selected rooftops. Following the mounting, cables were run from the panels to the plant room, where the generated energy would be managed. The three arrays were then connected to a high-efficiency inverter, which converted the generated solar power into usable electricity for the school. The installation was planned to avoid any disruption to the school’s daily activities. To achieve this, all work was scheduled to take place outside of school hours.
Once all components were in place, a comprehensive system test was conducted to commission the installation. Our rigorous testing ensured that the system operated efficiently and safely, ready to provide renewable energy to the school.
Outcome
The completed solar system at Ysgol Nant Y Groes is estimated to generate 79,560 kWh annually, significantly contributing to the school’s energy needs. This renewable energy solution will save approximately 15.32 tonnes of CO2 emissions each year, equating to the environmental benefit of planting 703 trees annually.
Beyond the immediate environmental and financial benefits, the solar PV system serves as a practical educational tool. It offers a real-world example of sustainability and renewable energy technology, providing a unique learning opportunity for students. By investing in renewable energy, the school not only reduces its carbon footprint but also inspires and educates the next generation about the importance of renewable energy and sustainability.
