Current Price of HJT Solar Panels in India
HJT technology is new in India, resulting in limited pricing information, mostly for high-power modules or complete kits. Recent data has been collected from manufacturers and vendors.
| Product / Vendor | Power Rating / System Size | Approx Price (₹) | Price per Watt (₹/W) |
| Reliance New Energy (full kit, 8 kW–15 kW) | Full kit | ₹55,999 / kW (quoted) | ~55.99 / W |
| “Standard” HJT modules | 730–750 W modules | ₹22 – 23 / W | ~₹16,000 to ₹17,000 per module |
| Pro‑L / Pro‑XL series modules | 690–760 W modules | ~₹25 / W | e.g. 760 W → ₹19,000 |
| Solar HELOC Plus (710 W) | 710 W module | ~₹20 / W | ~₹14,200 |
Types of HJT Solar Panels / Variants
Various types of heterojunction solar cell (HJT) modules, highlighting key variants:
- Monofacial HJT Modules: Capture sunlight only from the front, making them simpler and cheaper.
- Bifacial HJT Modules: Capture light from both sides, often using transparent conductive oxide layers; can achieve a bifaciality factor of 90% or more. Glass-glass encapsulation is common for protection.
- High-Power HJT Modules: Large modules (700 W+, G12 size) that optimize cell count and wafer size for cost efficiency, with some modules marketed at 730-750 W in India.
- Glass and Polymer/Backsheet Variants: Utilize glass fronts with a backsheet to minimize costs, while premium models opt for glass-glass construction for enhanced durability.
- DCR/Non-DCR Variants: In India, modules that meet domestic content requirements (DCR) qualify for subsidies, whereas non-DCR imports may not.
Factors Affecting HJT Solar Panel Price
Here are the main points regarding factors affecting HJT solar panel prices:
- Advanced Manufacturing Technology: Complex production processes increase costs compared to conventional panels.
- High-Quality n-Type Silicon Wafers: These wafers are more expensive but provide better efficiency and lower degradation.
- Glass–Glass and Bifacial Module Design: Dual-glass construction and bifacial technology enhance durability and power gain, increasing costs.
- Lower Production Scale: HJT panels are not yet manufactured at the same scale as PERC or TOPCon, leading to higher per-unit costs.
- Import Duties and Logistics: Imported modules incur customs duties and shipping costs, affecting pricing.
- Brand, Warranty & Certification Premiums: Reputable manufacturers charge more for quality assurance and certifications.
Key Features and Benefits of HJT Solar Panels
HJT (heterojunction) cells use layers of amorphous silicon on both sides of a crystalline silicon wafer, offering a hybrid architecture with several advantages:
- High Efficiency: Commercial HJT modules exceed 22% efficiency, with laboratory versions reaching 25–27%.
- Bifacial Energy Gain: These modules can absorb light from both sides, increasing energy yield, especially with reflective surfaces.
- Lower Temperature Coefficient: HJT modules exhibit less performance loss at high temperatures compared to conventional modules.
- Reduced Degradation: They are less prone to light-induced degradation (LID) and potential-induced degradation (PID), aiding in longevity.
- Good Low-Light Performance: Enhanced surface passivation leads to better performance in low-light conditions.
- Longevity and Stability: HJT modules are durable and can maintain higher power retention over 25+ years.
- Symmetric Structure: The design reduces susceptibility to degradation issues, promoting reliability.
These features are particularly beneficial in India’s hot climate, offering improved energy yields for rooftop systems.
