Manama, Bahrain—November 2, 2025: Foulath Holding, an industrial holding company with major steel investments and the parent company of Bahrain Steel and SULB, today announced its partnership with Yellow Door Energy, the leading sustainable energy developer in the Middle East and Africa, to embark on a groundbreaking sustainability initiative to develop a massive 123-Megawatt-Peak (MWp) solar project.

The solar power plant will be located in the southern region of Bahrain, near Bilaj Al Jazayer, covering a total area of approximately 1.2 square km. The project will utilise the latest advancements in solar energy technologies to optimise output and efficiency.
A power purchase agreement is in place for a 123 MW solar project in Bahrain that will span 14 sites including the world’s largest rooftop solar installation, a 50 MW system on top of a 262,000 m2 stockyard shed.
The installation will consist of 77,000 solar panels alone, installed across a new 262,000 sqm stockyard shed for Bahrain Steel BSC, a wholly-owned subsidiary of Foulath. Foulath Holding and Yellow Door Energy signed a power purchase agreement (PPA) for the project at the Gateway Gulf BH Investment Forum over the weekend.
Bahrain’s cumulative solar capacity stood at 66 MW by the end of last year, according to figures from the International Renewable Energy Agency (IRENA). In 2017, the country unveiled plans to bring online 255 MW of solar by the end of this year. The country’s Electricity and Water Authority kicked off a 100 MW solar tender last month.
After the establishment of the Sustainable Energy Unit (SEU) in Bahrain in 2014, a radical transition toward launching solar energy projects can clearly be observed. The SEU was established in collaboration between the national government and the United Nations Development Program (UNDP).
None of the participants mentioned any reported barriers to installation of solar PV in Bahrain. This is likely because solar panel installation is relatively new in Bahrain and the participants were not clear on the specifics involved. Effective dissemination of information is necessary, as explained later.

Definition: LFP 48V solar batteries refer to battery modules used in energy storage systems, which typically consist of 15 or 16 3.2V lithium iron phosphate (LFePO4) batteries connected together to form a system with a total voltage of 48 volts or 51.2 volts. 48V (51.2V) systems are commonly used in residential and commercial and industrial solar energy systems due to their higher voltage and relatively low current requirements, which reduces heat loss due to high current products and improves system efficiency.

This article will introduce in detail how to design an energy storage cabinet device, and focus on how to integrate key components such as PCS (power conversion system), EMS (energy management system), lithium battery, BMS (battery management system), STS (static transfer switch), PCC (electrical connection control) and MPPT (maximum power point tracking) to ensure efficient, safe and reliable operation of the system.

Off-grid solar systems are usually larger in inverter size due to independent operation and reliance on battery storage, matching Battery Bank capacity with peak load and integrating complex functions (e.g., battery management); whereas on-grid systems are smaller in inverter capacity due to interconnection with the grid, matching solar panel power and ensuring grid synchronization, with simplified functional design and a relatively low cost.
