LSES members met on Friday, October 16, at the Bossa Nova Hotel to discuss ongoing and upcoming projects. One of the main topics was the new PV Assessment Tool, developed by LSES in collaboration with the International Labour Organization (ILO).
Available in both Excel and web-based formats, this tool provides a fast and user-friendly way to size photovoltaic (PV) systems—with or without battery storage—and estimate investment costs, potential savings, and payback periods.
Designed with accessibility in mind, it can be used effectively even by non-specialists.

After a successful participation in the last years, the Lebanese Solar Energy Society was also present this year through a booth, where its members shared their expertise with visitors and exhibitors during four consecutive days from May 6 till may 9 2025, at the Seaside Arena in Beirut.
Following a difficult year of war and conflicts, this year's edition, with the topic of "Rebuilding Lebanon," brought together a large number of stakeholders from the fields of renewable energy, construction, architecture, and interior design. LSES members who attended throughout the duration of the four days were able to have insightful discussions and make new business connections.
The LSES 2025 IFTAR took place On March 28, 2025, at the Abdel Wahab Restaurant in Sodeco Beirut.
During the event, former LSES president and founder Eng. Walid el Baba was honored with two trophies: one from the OEA fourth branch in recognition of his service as a senior active mechanical engineer and another from LSES in acknowledgement of his lifetime contributions to the Renewable Energy sector.
The project, with a very simple idea and approach without sophisticated technical innovation aspect, consisted in providing the supply and proper operation of 26 portable solar power packs of capacity 1000 Watts with Battery for partial sustainable energy alternative solution using clean energy source (PV solar) to meet urgent local needs of low income families houses, half of the units to be delivered to apartments affected by the explosion of Beirut port, the other half to apartments in Beirut suburbs mainly in marginalized areas .
The project aimed to reduce social and energy poverty by reducing electric bills of beneficiaries and familiarize those families to use sustainable energy source and be aware of solar applications and climate change effects. It aims to limit the effects of the energy starvation on the most vulnerable families which would affect the education of their children, the domestic day to day use of the families including lighting, internet, and refrigerators.
The Solar Power pack will remain the possession of LSES under a “Free Leasing “contract, allowing to control its traceability, proper operation as well as the good use and durable maintenance.
The beneficiaries have been selected according to a specific questionnaire
In addition to the above, the project contributed in engaging the community through following actions:
The duration of the project was of 11 months.
During 4 to 5 months of operation regular technical visits were planned for data collections in order to establish an evaluation document for the future.
This project has also served as a demonstration tool for encouraging the replication of this type of portable packs, with various capacities, at a larger scale within residential buildings all over Lebanon
By implementing such demonstration project in those selected apartments, the use of sustainable solar energy through the energy pack will be:
After receiving the green light for the grant in 2022 the contract was signed mid-January 2023 between LSES and Global Environment Facility (GEF) Small Grants Program (SGP) Lebanon implemented by UNDP.
Works were launched under the supervision of Mr. Adnan Melki as national coordinator from UNOPS for all day-to-day matters, and LSES Engineer Ziad Doumit as project manager.
