G1 vs. M10 Solar Cells – What Do They Mean for Panel Performance?

 Title - G1 vs. M10 Solar Cells – What Do They Mean for Panel Performance?

When it comes to solar panel manufacturers and solar panel providers in India, technical specifications often become marketing jargon. Among these, "G1" and "M10" solar cells are frequently touted, but what do they actually mean for performance?

G1 cells typically refer to 166 × 166 mm half-cut PERC (Passivated Emitter and Rear Cell) solar cells. They’re a modern standard, used widely by leading panel makers. On the other hand, M10 cells are slightly larger in size, i.e., 182 × 182 mm. Because they’re larger, panels made of M10 cells require fewer cells overall and reduced inter-cell wiring, which leads to improved electrical efficiency.

Key Performance Factors

Each cell type supports high-efficiency values; G1 cells have 21-22%, while M10 cells offer a slightly higher value. Furthermore, power outputs vary on the panel; typical G1 panel power ratings range from 430 to 450 W, while M10-based panel ratings can exceed 450 W within the same form factor. In terms of reliability, G1 enjoys a more proven manufacturing realm throughout the years, where the newer M10 technology claims to deliver advanced results in future. Both types also degrade at approximately 0.5% per annum.

Thermal performance is also quite similar; however, the larger cell size of M10 and its fine-tuned design can offer slight advantages under high-temperature conditions. While G1 cells act in support of cost-effectiveness and are still widely available, M10 is now close to becoming the first choice among solar panel manufacturers when it comes to maximizing module efficiency and output.

So, Which One Should You Choose?

Considering projects on a budget, G1 panels are the way to go, based on their historical performance and price point. On the contrary, somewhat more efficient and less spacious, M10-based modules fit the bill. Finally, it is the product quality and reliability from a reputed solar panel provider in India that remains an indispensable factor in achieving long-term solar panel performance and return on investment, be it G1 or M10.

Choosing the Right Solar Panel Provider

Both G1and M10 cell-based panels perform well if manufactured by a reputed solar panel manufacturer. Certain aspects should be considered in making this decision: long product warranties, typically 25 years or more; degradation guarantees; third-party test certifications including IEC and UL; and very solid local support and service infrastructure. These factors guarantee that your solar investment will withstand time, produce its specified amount of power and be of utmost utility in general.

Why Gautam Solar Stands Out

Being one of the prominent solar panel providers in India, Gautam Solar brings unmatchable capabilities to the industry. Having project expertise in sourcing and manufacturing high-performance modules using G1-M1 and the latest M10 solar cells, the company offers custom-made solutions for residential, commercial, and utility-scale applications. From system design to product supply, installation, and after-sales support, Gautam Solar offers a comprehensive range of services.

While the performance differences between G1 and M10 cells are significant, partnering with a trusted supplier like Gautam Solar will ensure that your investment is optimized through advanced technology, tailored solutions, and great service.
