#topcon panels

Shifting to solar energy so as to reduce the dependence on hazardous fossil fuels requires the production of solar modules that deliver maximum performance in minimal space, especially for large-scale projects. Among the top high-efficiency solar modules, Gautam Solar’s G12R Rectangular cells are setting new benchmarks for what constitutes the best N-Type TOPCon Solar Modules in rooftop solar installations and utility-scale solar power projects. Integrated seamlessly with TOPCon Modules, the G12R technology is practical and durable and this blog aims to explain how.

The Design

G12R rectangular cells optimize the cell's dimensions into a rectangular format, advancing the cutting-edge G12 wafer design. This redesign is a significant structural refinement that imparts much higher efficiency, i.e., more output per unit, and also delivers more reliable performance in the long run than other types of cells.

Gautam Solar’s G12R design features 132 half-cut rectangular cells integrated into the N-Type TOPCon technology that efficiently delivers a wattage output up to 640 WP. The unique leading-edge module also boasts of delivering an efficiency of up to 24% while meeting BIS (national) and UL (international) certification requirements that ensure flawless performance while guaranteeing safety.

Outperforming Predecessors by a Margin

There is no doubt that G12R cells make the best N-Type TOPCon Solar Modules. The design offers numerous advantages in comparison to its predecessors.

Reduced Shading Risks

Often, solar panels experience disruptions due to shading when a cloud blocks the sunlight from reaching parts of the solar panels, as cells are connected in a series. However, being half cut, the G12R cells reduce the possibility of disruptions as the cells act more independently. The independence of sections is instrumental in reducing the impact of partial shading and prevents power loss as other cells are still able to generate power. This is because half cells are connected through a parallel connection.

Minimal Resistive Losses

Gautam Solar’s G12R cell-powered solar panels feature MBB technology in manufacturing, which effectively enhances the electrical conductivity of the whole module. The technology uses thinner busbars to connect individual wafers to maximize output. Coupled with a parallel connection, it results in lower current paths, and reduction of the energy loss that occurs while the current is travelling through the components of the panel.

Higher String Power and Cost-Efficiency

The module configuration employed in using G12R increases the voltage and current power significantly. At the same time, the rectangular design makes it possible to fit more cells in the same panel, which results in higher efficiency and cost savings for consumers, as they would now require fewer panels to achieve the desired current power. The reduced space utilization and mounting costs make logistics and installation more affordable, increasing the adaptation of renewable energy for both commercial and domestic use.
