M10 Bifacial Mono-PERC Solar Cells: Why This Technology Dominates India's Solar Module Market in 2026
If you are a solar panel distributor, installer, or procurement manager sourcing modules for Indian government schemes like PM Surya Ghar or PM Kusum, there is one solar cell format that keeps appearing at the top of every supplier’s product sheet: M10 Bifacial Mono-PERC. Understanding why this technology has become the industry standard in India — and why it outperforms alternatives in real-world conditions — is essential knowledge for every solar supply chain professional in 2026.
What Is an M10 Solar Cell?
The M10 designation refers to a specific wafer size standard in the solar industry — 182 mm × 182 mm. This wafer size represents a significant step up from the older M6 (166 mm) and G1 (158.75 mm) formats. When paired with Mono-PERC (Passivated Emitter and Rear Cell) technology and a bifacial design — which allows the cell to absorb light from both front and rear surfaces — you get a product that offers some of the most compelling efficiency and output numbers available in crystalline silicon technology today.

The Technical Advantages of M10 Bifacial Mono-PERC
1. Higher Power Output per Module
Larger wafer area means more photons can be captured per cell. An M10 Mono-PERC module typically delivers 530 Wp to 560 Wp in a standard 60-cell (half-cut, 120-cell) configuration — compared to 375–400 Wp from older M6 cells. This means fewer modules are needed for the same system capacity, reducing balance-of-system (BOS) costs including mounting structures, cables, and labour.
2. Bifacial Gain in Indian Conditions
The bifacial design enables the rear of the panel to absorb reflected albedo light from the ground surface. In Indian rooftop conditions with light-coloured surfaces or elevated mounting, bifacial gains typically range from 5% to 15%. In ground-mounted agricultural installations typical of PM Kusum Component A projects — especially in open, bright fields — rear-side gains can approach 20%, significantly improving energy yield.
3. Half-Cut Cell Architecture
Most M10 modules use half-cut cell technology, which divides each cell into two halves. This reduces resistive losses and improves performance in partial shading conditions — extremely relevant for residential rooftops where shadows from water tanks, antennas, or adjacent structures are common. Half-cut cells also run cooler, extending module lifespan.
4. Excellent Temperature Coefficient
M10 Mono-PERC cells typically exhibit a temperature coefficient of power (Pmax) around -0.35%/°C. Given that module surface temperatures in India can easily reach 60–70°C in summer, a tight temperature coefficient translates directly to preserved energy output during the hottest parts of the day — when electricity demand (and its value) peaks.
Manufacturing Advantages That Benefit Distributors
M10 cells are not only technologically superior — they are also easier to manufacture at high volume and consistent quality due to the maturity of the M10 production ecosystem. Leading solar cell manufacturers in India have invested heavily in M10-compatible production lines, meaning supply reliability is strong.
Websol Energy System, operating as a certified solar cell manufacturer in India, manufactures M10 Bifacial Mono-PERC solar cells at its facility in Falta, West Bengal — equipped with advanced automation and stringent quality control for consistent cell efficiency across production batches.
How M10 Cells Perform Across India’s Solar Applications
PM Surya Ghar Residential Rooftops
For 1 kW–3 kW residential rooftop systems, M10 modules allow system integrators to deliver higher capacity within limited roof space. A typical 3 kW system using M10 540 Wp modules requires only 6 panels — versus 8 panels with older 375 Wp modules — reducing structural load and installation complexity.
PM Kusum Agricultural Installations
In ground-mounted Component A and C installations, M10 bifacial modules deliver measurably better energy yield per square metre of land use. Higher bifacial gain in open agricultural fields further improves project economics, making M10 bifacial the preferred choice for competitive bid pricing.
M10 vs Other Cell Technologies: A Quick Comparison
M10 Mono-PERC Bifacial vs TOPCon: TOPCon offers slightly higher efficiency (22%–24%) but at significantly higher manufacturing cost. For most PM Surya Ghar and PM Kusum applications, M10 Mono-PERC hits the optimal efficiency-cost sweet spot.
M10 Mono-PERC Bifacial vs HJT: HJT (Heterojunction Technology) offers excellent low-light performance but involves higher capital cost and more complex manufacturing. M10 Mono-PERC remains more commercially accessible for Indian government scheme volumes.

Frequently Asked Questions
Q1: What does M10 mean in solar cells?
M10 refers to the wafer size standard of 182 mm × 182 mm used in solar cell manufacturing. It represents a newer, larger wafer format that enables higher power output per module compared to older M2, M6, and G1 wafer sizes.
Q2: What is the typical efficiency of M10 Mono-PERC bifacial solar cells?
M10 Mono-PERC bifacial solar cells typically achieve module efficiencies between 20.5% and 22%, with front-side cell efficiencies commonly in the 21–22.5% range in leading Indian manufacturing facilities.
Q3: Are M10 bifacial modules suitable for PM Surya Ghar rooftop installations?
Yes. M10 bifacial Mono-PERC modules are well-suited for PM Surya Ghar installations, offering higher power output in less roof space, good temperature performance, and compliance with MNRE efficiency standards.
Q4: What bifacial gain can be expected from M10 modules in India?
In typical Indian rooftop and open-ground conditions, bifacial gain ranges from 5% to 20% depending on mounting height, tilt angle, and ground surface reflectivity (albedo). Light-coloured or reflective surfaces maximize rear-side energy capture.
Q5: What is the power output range of M10 Mono-PERC bifacial modules?
Depending on configuration and number of cells, M10 Mono-PERC bifacial modules typically output 525 Wp to 575 Wp per module — significantly higher than older generation 144-cell modules using G1 or M6 wafers.
