Replacing the use of aluminum with steel is a bet by Risen Energy for your photovoltaic equipment. This new structure is capable of reducing carbon emissions by 6.2 times and energy consumption by three times.
“The life cycle carbon emissions of the module with a steel alloy structure (by 1 GW) are reduced by 77% compared to the aluminum structure”, highlighted Felipe Toledo, LATAM product manager at Risen.
“With the increasing proportion of recycled steel application, the percentage will be even higher. If recycled 100% steel is used, up to 95.5% of carbon emissions can be reduced,” he added.
According to him, through this adaptation to steel, the expectation is to achieve the goal of carbon neutralization. “The steel production capacity is much greater than that of electrolytic aluminum.”
“This in the long term will greatly affect the demand for aluminum in the photovoltaic market, resulting in a possible shortage of supplies, impacting the increase in equipment costs and reducing the popularization of new energies”, explained Toledo.
Below are the main features of product performance, according to Toledo:
- Better performance in tear resistance. The tear strength test at the mounting hole location for the high-strength alloy steel frame showed 31% stronger than the aluminum alloy frame;
- A new type of environmentally friendly steel sheet. Double layer for better corrosion resistance. The steel structure has the ability to self-heal through a dense protective film of “galvanized aluminum and magnesium”;
- Although the alloy steel structure is heavier than the aluminum structure, the maximum module weight increase does not exceed 2 kg, and the increase per square meter does not exceed 0.6 kg. There are no major costs or difficulties in installation;
- The high-strength alloy steel frame module also passed the scale-certified low-temperature dynamic mechanical load test (-40°C/1000 Pa/1000 cycles), and the low-temperature static load test (-40 °C/5400 Pa/ 2400 Pa);
- No galvanic corrosion phenomenon. In the galvanic corrosion pattern, the electrochemical potential energy of aluminum and steel is 0.15V, much lower than 0.6V under electrochemical corrosion conditions;
- The machining precision of the alloy steel module is compatible with the precision level of the aluminum structure, fully suitable for photovoltaic module production and application. The cross-sectional shape of the steel and aluminum edges is almost identical to the installation method, without incurring any additional costs.
Lines that contain the solution
According to Risen's product manager, high-strength alloy steel structures can be found as an option in the Titan Series lines, in the N-type NewT@n cell line and also in the new heterojunction (HJT) cell line. Hyper-Ion, which will be available in the coming months for sale across the global market.
