The Risen Hyper-ion (HJT) series comprises double-sided, heterojunction modules designed for maximum energy yield under real-world operating conditions - especially when conventional designs lose effectiveness. Thanks to HJT technology and high thermal stability, the modules maintain production better during summer and on installations with poorer ventilation, translating to higher annual yields and a more predictable investment return.

The key difference lies in the 0BB (busbar-free) cell architecture and the proprietary, stress-free Hyper-link interconnection technology, which enhances connection durability, minimizes module losses, and improves resistance to micro-cracks during installation and thermal cycling. The modules also feature high bifaciality, effectively utilizing reflected light - particularly on light-colored roofs, gravel surfaces, and farms with appropriately selected substrates.

This is a sensible choice for industrial installations and PV farms where lower BOS costs and stable power output matter, as well as for projects focused on carbon footprint and long-term power retention.

What owners get
High efficiency via HJT technology

Heterojunction (HJT) cells deliver module efficiency of 22.5-23%, and a low temperature coefficient helps maintain higher output in summer and on poorly ventilated installations compared to conventional PERC/TOPCon modules.

Very long 30-year power warranty

The manufacturer offers a 30-year linear power warranty plus a 15-year product warranty, a premium standard in the HJT segment that supports predictable ROI on industrial-scale projects.

0BB architecture and Hyper-link technology

The busbar-free (0BB) cell design combined with Risen's proprietary stress-free Hyper-link interconnection reduces electrical losses and improves resistance to microcracks during transport, installation, and thermal cycling.

High bifaciality for utility-scale PV farms

Bifacial modules with up to 85% bifaciality effectively capture reflected light, which, with suitable ground albedo (light roofs, gravel), meaningfully boosts annual energy yield in large-scale installations.

Specs on par with the HJT segment leaders

Power of 700-715 Wp and efficiency up to 23% match leading HJT peers - DAS Solar (715 Wp, 23%), New East Solar (715 Wp, 23.02%), and BECSA (715 Wp, 23%) - confirming Risen is at the forefront of current bifacial HJT technology, while its Tier-1 bankable status strengthens project financing credibility.

Trade-offs
Higher cost than TOPCon/PERC modules

HJT technology involves higher cell production costs (additional a-Si layers and silver paste) than mainstream TOPCon or PERC modules, which can translate into higher CAPEX and a longer payback period for projects with limited BOS budgets.

Inconsistent bifaciality figures across manufacturer releases

Different official Risen materials quote bifaciality as both 85%±5% and 85%±10% for the same series, making precise energy yield modeling harder without confirming the current datasheet for the specific production batch.

Notes from the database
  • Efficiency of 22.5% is 0.5pp below the HJT 700-750W median (23.0%)
  • Power density of 225.3 W/m² is 4.9 W/m² below HJT 700-750W median (230.2 W/m²) - needs more roof space
  • Temperature coefficient of -0.24%/°C matches the HJT 700-750W median
  • At 40.0 kg, this panel is 1.7 kg heavier than the HJT 700-750W median (38.3 kg) - more demanding for installation crews
  • Bifaciality factor of 90% can add 4-14% extra yield with reflective mounting surface

About the Hyper-ion Series (Heterojunction) Bifacial Module series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What is the temperature coefficient of the Risen Hyper-ion HJT module and does it matter in summer?
The Risen Hyper-ion HJT module has a power temperature coefficient of -0.24%/°C - one of the lowest in the industry, well below the -0.35%/°C typical for PERC or TOPCon modules. In practice, at 70°C module surface temperature the power loss is roughly 10.8% versus 15.75% for PERC. On rooftops with limited ventilation or during hot summer days, the Hyper-ion will generate noticeably more energy than competing technologies.
What is the 0BB and Hyper-link technology in Risen Hyper-ion panels and why does it matter?
0BB (zero busbar) removes metallic busbars from the cell surface, eliminating shading and resistive losses at the cell level. Risen's proprietary Hyper-link interconnection bonds cells at room temperature (25°C) using 24 thin module-level connections - completely stress-free. The result is reduced risk of microcracks during installation and thermal cycling, higher cell efficiency (up to 26.2%), and better long-term reliability of electrical connections throughout the module's service life.
How much extra energy does the Risen Hyper-ion produce thanks to its bifacial design, and on which installations does it pay off?
The Risen Hyper-ion achieves up to 90% bifaciality, meaning the rear side can capture up to 90% of the energy relative to the front side. Risen claims over 3% higher annual yield compared to mainstream bifacial modules. You'll see the biggest gains on ground-mounted farms with light-colored ground cover (gravel, concrete, light grass), white roofing membranes, or elevated structures like pergolas and carports where diffuse light can reach the rear side.
What warranties does the Risen Hyper-ion come with and what do they cover?
Risen provides a 15-year product warranty covering material and manufacturing defects, plus a 30-year linear power warranty guaranteeing at least 80% of rated power output after 30 years of operation. Risen Energy is a Tier 1 manufacturer listed on the Shenzhen Stock Exchange, which provides additional financial backing for warranty claims over that 30-year horizon.
Are Risen Hyper-ion 715W modules suitable for large-scale solar farms, or are they aimed at residential rooftops?
Risen Hyper-ion is primarily designed for commercial and utility-scale PV installations. At 715 Wp, dimensions of 2384×1303 mm and a weight of 40 kg, it is not practical for pitched residential rooftops. On solar farms, large-format modules reduce installation time, lower BoS costs (fewer modules, connections, and mounting structures), and improve LCOE. The HJT cell technology ensures the array performs reliably even in high-temperature climates where inverter MPPT tracking benefits from a stable, flat power curve.
Is the Risen Hyper-ion a good fit for projects with low-carbon requirements and ESG reporting obligations?
Yes. HJT manufacturing uses lower process temperatures than PERC or TOPCon, resulting in a carbon footprint below 400 kg eq CO₂/kWp for the Risen Hyper-ion - significantly less than standard PERC modules. If your project involves investors, lenders, or regulations requiring embodied-carbon documentation, this series has a measurable advantage, and Risen Energy provides LCA-compatible environmental data to support formal ESG or sustainability reporting.
