ERC-NUL Strengthens Solar Thermal Systems Capacity in Lesotho Through Advanced SOLTRAIN+ Training Programme

The Energy Research Centre at the National University of Lesotho has taken a significant step in advancing renewable energy capacity in the country through a focused training programme aimed at strengthening solar thermal systems development. The initiative reflects growing national and regional interest in clean energy solutions that reduce dependence on conventional fuels and improve energy efficiency across key sectors. The training programme was held from 26 to 29 May 2026 and brought together energy professionals and solar thermal installers from different parts of Lesotho. It formed part of ongoing efforts to build technical expertise that supports sustainable development and energy transition goals. With support from the Southern African Solar Thermal Training and Demonstration Initiative, known as SOLTRAIN+, the programme delivered both practical and theoretical knowledge to participants.

The training was designed to bridge the gap between classroom learning and real-world application in renewable energy systems. Participants engaged in structured sessions that covered solar thermal system applications, system design, feasibility assessments and energy auditing methodologies. These topics were delivered in a way that encouraged practical understanding rather than theoretical learning alone, ensuring that professionals could apply the knowledge directly in their work environments. The inclusion of system dimensioning and performance evaluation helped participants understand how to design efficient and cost-effective installations. This approach strengthened the technical capacity of installers and engineers working within Lesotho’s growing renewable energy sector.

A key feature of the programme was the integration of site visits and system inspections, which allowed participants to observe operational solar thermal systems in real-world settings. These visits included local industries and hospitality establishments where energy efficiency practices are increasingly being implemented. Participants were able to assess system performance, identify potential improvements and understand how renewable heating and cooling technologies operate under different conditions. This hands-on exposure helped reinforce classroom lessons and provided practical insights that are often missing from traditional training programmes. It also encouraged knowledge sharing between professionals working in different sectors of the energy industry.

Through the SOLTRAIN+ initiative, the Energy Research Centre at the National University of Lesotho continues to play a central role in building technical expertise in renewable energy technologies. The programme supports the development of skilled professionals who can design, install and maintain solar thermal systems across residential, commercial and industrial settings. It also contributes to broader regional goals of promoting clean energy adoption and reducing greenhouse gas emissions. By focusing on capacity building, ERC-NUL is helping to create a workforce that is better equipped to support Lesotho’s long-term energy transition. The collaboration with SOLTRAIN+ strengthens regional cooperation in renewable energy development across Southern Africa.

Beyond training programmes, ERC-NUL has expanded its role in supporting local industries and commercial buildings through free energy audits and technical recommendations. These audits help organisations identify areas where energy consumption can be reduced and efficiency improved. The recommendations provided often include practical measures such as system upgrades, better insulation and the integration of renewable energy technologies like solar thermal systems. This support is particularly valuable for businesses seeking to reduce operational costs while improving environmental performance. It also reinforces the centre’s commitment to applied research and community impact.

The growing demand for renewable energy solutions in Lesotho highlights the importance of initiatives such as this training programme. Solar thermal systems offer a practical solution for water heating and industrial energy needs, particularly in sectors with high thermal energy demand. By equipping professionals with the necessary skills, ERC-NUL is helping to accelerate the adoption of these technologies across the country. The training also contributes to national energy security by reducing reliance on imported fuels and promoting locally available renewable resources. This shift supports both economic resilience and environmental sustainability.

The success of the programme demonstrates the value of partnerships between academic institutions, regional initiatives and industry stakeholders in advancing clean energy development. ERC-NUL continues to position itself as a leading centre for renewable energy research, training and technical support in Lesotho. The integration of practical training, field exposure and energy auditing services ensures that participants gain comprehensive skills that can be applied immediately. As solar thermal technologies continue to evolve, ongoing capacity building will remain essential for maintaining industry standards and improving system performance. The collaboration with SOLTRAIN+ reinforces this long-term commitment.

The Energy Research Centre’s continued efforts reflect a broader national strategy to expand renewable energy access and improve energy efficiency across all sectors. By investing in skills development and technical training, Lesotho is strengthening its ability to implement sustainable energy solutions at scale. The solar thermal training programme marks another important milestone in this journey, providing professionals with the tools needed to support future growth. With sustained support and continued collaboration, ERC-NUL is expected to play an even greater role in shaping the country’s clean energy landscape. The programme underscores the importance of practical training in driving meaningful energy transformation.
