ENERGY EFFICIENCY IN EDUCATION
greater flexibility in panel placement, enabling efficient energy generation even from small or obstructed roofs. Another advantage is ease of operation. DC- optimised systems with Power Optimizers provide module-level monitoring, enabling faults to be quickly pinpointed, with personnel automatically notified of issues. This capability helps prevent downtime and simplifies maintenance.
DO YOUR HOMEWORK: PREPARING FOR A POWERING THE
FUTURE OF EDUCATION WITH SOLAR ENERGY
As energy costs rise and sustainability pressures increase, schools and universities are looking for ways to reduce expenses while setting a positive example for future generations. In this article,
Christelle Barnes, UK country manager at SolarEdge Technologies, explores how educational institutions can leverage solar energy to achieve these goals, offering insights on funding options, installation, and long-term maintenance strategies
A
s energy costs continue to rise, schools and universities operating on tight budgets
are feeling the strain. At the same time, they face growing pressure to adopt sustainable practices and set an example for future generations. In this environment, solar energy offers a practical solution, providing both cost savings and sustainability benefits.
SUSTAINABILITY The main reason for educational facilities to adopt solar energy is the potential to achieve significant cost savings. Energy bills are a major ongoing expense, and installing a solar system lets schools and universities generate their own electricity, particularly during daylight hours when energy usage is highest. This can significantly reduce electricity bills and free up funds for other needs. In addition to savings, solar installations help schools and universities to meet local sustainability goals. What’s more, they also provide a valuable learning resource for students, allowing them to explore renewable energy and climate change. This exposure can inspire future environmental advocates or careers in the growing renewable energy sector.
CUTTING COSTS AND IMPROVING
OVERCOMING BARRIERS TO ADOPTION While the advantages of installing onsite solar
generation are clear, perceived hurdles such as upfront costs can be a barrier to adoption for some institutions. Fortunately, government support programs like the Public Sector Decarbonisation

Scheme offer grants to help public sector bodies, including schools, fund energy efficiency projects. Alternatively, lease financing models are available that enable payment for solar systems through manageable, ongoing instalments. Another potential barrier stems from concerns that solar systems may be difficult to operate and maintain, especially for maintenance teams that have no previous experience with the technology. However, by choosing intuitive, low-maintenance solutions, schools and universities can maximise the benefits of their solar investment without burdening staff with specialised tasks.
TECHNOLOGY AS AN ENABLER Advancements in solar technology, especially
in solar inverters, are key to addressing these challenges. Inverters convert DC electricity generated by solar panels into AC electricity used in buildings and are critical to system efficiency. In traditional string inverter systems, panels are connected in series, which means the under- performance of one panel, for instance due to shading or soiling, can reduce the output of every connected panel. This is a common challenge on school and university campuses where nearby trees or structures may shade parts of the solar array. As a result, DC-optimised inverter systems
are gaining popularity. In these systems, Power Optimizers are placed on each panel pair, allowing them to operate independently from other connected panels. This minimises the impact of shading or soiling, improving overall energy production. DC optimisation also offers
SUCCESSFUL SOLAR INSTALLATION The first step when making an investment in solar is to partner with a reputable installer who can assess the suitability of the buildings, identify potential issues like shading, and help to define clear goals. For example, some schools and universities may want to install a large system for maximum energy self-sufficiency, while others, perhaps due to budgetary or other factors, may choose a smaller system that can be expanded over time. The installer will also take into account any
planned developments, such as future site expansions, or the introduction of onsite electric vehicle charging. By understanding how energy requirements may change over time, they can design a tailored solution that is both effective and scalable for the future.
FIRST When installing a solar system, safety and security should be the highest priority – particularly for educational facilities responsible for the well-being of students, staff and visitors. Your installer can recommend safety features for enhanced protection. For example, SafeDC reduces voltage in solar arrays to touch-safe levels, allowing maintenance teams or firefighters to work without electrical hazards. Also important is arc fault detection, which detects high temperatures or faults and automatically powers-down the system to prevent more serious issues. It’s a sign of the times that safety concerns now extend beyond fire hazards to include cybersecurity. Schools, unfortunately, have become targets of hackers, as evidenced by a recently reported ransomware attack on a secondary school in Cheshire. While the attack didn’t involve a solar system, it demonstrated that when left unprotected, online systems can provide an entry point into school networks. However, by choosing an inverter with integrated cybersecurity protocols, schools and universities can ensure the protection of sensitive data from cyber threats.
PUTTING SAFETY AND CYBERSECURITY
A SUSTAINABLE SOLUTION Adopting solar energy is a sustainable, cost-
effective, solution for schools and universities. Despite perceived challenges, the financial and environmental benefits make it an invaluable investment. With the availability of a range of funding options, advanced technology, and a focus on safety and security, schools and universities can successfully navigate the transition to clean energy.
