Egypt’s Benban solar project combines 259 MW with denser panels and 120-MWh battery
Buried deep in the desert of Egypt’s Aswan area lies the giant Benban solar plant, and it is witnessing a technological revolution.
Nefer Benban has ordered high-efficiency 650- and 655-watt solar panels from the company AIKO. In this case, the company does not require an expansion into unexplored land but utilizes the concept of a dense placement of panels along with a 120-megawatt-hour (MWh) storage system.
Thus, the solar energy facility becomes one designed for maximum generation, production efficiency, and transmission.
Infinity Power is teaming up the solar farm with a 120 MWh battery energy storage system intended to deliver two hours of grid energy shifting.
The metal was transferred to the back of the cell
Standard crystalline-silicon solar cells use silver conductive metal lines applied directly to the front surface in order to collect electricity produced by the cell. But these metal lines hinder the process by blocking the sunlight that reaches the active silicon beneath.
The ABC technology transfers the conductive lines to the back of the cell. By removing any front wiring, a clear surface area is obtained for sunlight absorption.
For the Nefer Benban project, the company chose AIKO-A-GRH-66Dw modules, which have dimensions of approximately 7.8 ft x 3.7 ft (28.8 sq ft) with a peak efficiency of 24.2%. These modules have a power rating of either 650W or 655W.
4% is seen in the design
According to AIKO, the ABC series produces 20 W more than leading Tunnel Oxide Passivated Contact (TOPCon) panels of equal physical size.
This additional power density changes the math for mounting rows: project developers can pack significantly more watts in the same land area without requiring any increase in land use or additional rack systems.
In the case of Nefer Benban, AIKO predicts 4% more capacity within the same landmass, 5.8% more total energy generated over the life cycle, 4% lower cost per watt for a balanced system, and 3.7% lower levelized cost of electricity.
These are the figures the manufacturer posted prior to the commissioning of the plant.
The 259 MW figure has another dimension to it
Documentation for the project mentions different operating figures for Nefer Benban. AIKO defines the project as having a 259-megawatt capacity.
On the other hand, Infinity Power, which is the lead developer of the project, gives a figure of 258.5 MW-peak (MWp) while talking about grid delivery from the 200 MW solar power plant. It should be noted that there is a significant difference between potential DC panel capacity and AC grid output capacity.
The project is being developed at the Benban Solar Park in Aswan by Infinity Power and Hassan Allam Utilities, with Hassan Allam Construction installing the AIKO modules.
AIKO plans to deliver modules in one month after signing the contract in Q4 2026.
The battery transports electricity, not panels
The second engineering development maximizes time rather than physical space. Infinity Power is teaming up the solar farm with a 120 MWh battery energy storage system intended to deliver two hours of grid energy shifting.
Solar panels produce electricity only under conditions of sun exposure. The battery stores the electricity produced in the middle of the day and uses it later, thus decoupling generation timing from grid delivery.
Originally the power purchase agreements aimed for commercial operation in the third quarter of 2026; now, according to the timelines published by AIKO, it will be the fourth quarter of 2026.
Benban squeezes more out of the same acre
Upon becoming fully operational, Nefer Benban is estimated to produce an amount of electricity sufficient for powering some 57,000 typical U.S. homes (or 311,000 Egyptian families), at the expense of preventing emissions of up to 385,000 short tons of CO2 into the atmosphere each year.
And here is the key idea: The solar farm does not require any extra desert acreage—rather, it seeks to squeeze more power out of the same plot of desert it already possesses.
By shifting the electrical contacts behind the cell, engineers manage to fit 4% more power-generating capacity on the same area of acreage. Adding a 120 MWh battery allows flexibility in delivery.
Ultimately, Nefer Benban becomes the embodiment of a new era of clean energy development, one in which the future of solar power depends on squeezing the most from its acreage and time rather than extending borders.
