Mallard House Solar Panels | GW Power-Safe Commercial Engineers

Mallard House

In this project, we, in collaboration with our valued client Hobson and Porter and with the support of East Riding Council, installed 50 Longi HiMo5 410W panels. Unlike an integrated roof system, these panels were mounted on top of the roof using a specialised mounting system.

The on-roof mounting system offered several advantages during the installation process. Its simplicity and user-friendly design made the installation process straightforward and efficient. The system’s ease of use allowed us to save time and effort, ensuring a smooth and hassle-free installation experience.

One notable advantage of this mounting system was its forgiving nature when it came to adjustments. Ensuring that the solar system is perfectly aligned and level (plumb) is essential for optimal performance. The mounting system’s flexibility and adjustability provided us with the ability to make precise adjustments, ensuring that the panels were positioned correctly for maximum efficiency.

By utilising the Longi HiMo5 410W panels and the accommodating on-roof mounting system, we were able to deliver a high-quality solar energy solution for Mallard House. The combination of advanced solar panel technology and an easy-to-use mounting system contributed to a successful project outcome.


During the Mallard House project, one of the challenges we encountered was the height of the building. As it was the beginning of summer, some areas still experienced windy conditions. Transporting the panels to such heights using a hoist presented a significant challenge for our team.

Installing solar panels at significant heights requires careful planning and execution to ensure the safety of both the installation team and the equipment. Windy conditions can make the process even more demanding, as it adds an additional element of risk.


To tackle this challenge, we employed stringent safety protocols and adhered to industry best practices. We ensured that our team members were properly trained and equipped with the necessary safety gear to work at height. Additionally, we closely monitored weather conditions and adjusted our installation schedule accordingly to minimize the impact of wind.

Overcoming these challenges required a combination of experience, expertise, and careful attention to detail. Our team’s dedication to safety and commitment to delivering a high-quality installation ensured that the project was completed successfully, despite the difficulties posed by the building’s height and the wind.


It’s crucial to prioritise safety in every project, particularly when working at significant heights. By addressing these challenges head-on and implementing appropriate safety measures, we were able to carry out the installation at Mallard House while maintaining the highest standards of quality and ensuring the well-being of our team.

Inside Mallard House, we mounted a Solis 20KW inverter, which served as the central control unit for the solar energy system. In addition to the inverter, we also installed various controls and surge protection devices to enhance the system’s efficiency and safeguard against electrical surges.

Having a plain, free wall to set up the equipment allowed us to organise everything neatly. This not only facilitated easy access for maintenance and monitoring but also contributed to the overall aesthetic appeal of the installation.

The Solis 20KW inverter played a crucial role in converting the direct current (DC) electricity generated by the solar panels into alternating current (AC) electricity suitable for use within the building. It is an essential component that ensures the effective utilisation of the solar energy system’s output.

Alongside the inverter, the inclusion of controls and surge protection devices further enhanced the system’s performance and safety. Controls helped monitor and regulate the energy flow, optimising energy production and utilisation. Surge protection devices protected the system from sudden voltage spikes and electrical surges, ensuring the longevity and reliability of the equipment.

By mounting the Solis 20KW inverter, controls, and surge protection devices neatly on a dedicated wall, we achieved a clean and organised setup. This not only enhanced the functionality and efficiency of the solar energy system but also contributed to a visually pleasing installation.

Overall, Mallard House was a satisfying job due to the seamless installation process made possible by the user-friendly on-roof mounting system. We take pride in delivering projects that not only offer reliable and efficient energy solutions but also provide ease of installation and long-term performance.
