The Risen TITAN RSM132-8-655M-675M series are large-format modules engineered for maximizing yield from one string and one mounting structure, specifically tailored for ground-mounted installations and large rooftops. Utilizing the 132 monocrystalline PERC technology helps extract more energy in real-world conditions, while excellent low-light performance minimizes losses during early mornings, winter, and overcast periods. In practice, this translates to more stable energy production and greater project profitability, where every percentage point counts.

A notable feature is the enhanced resistance to PID, crucial for long cable runs and challenging environmental conditions. The manufacturer employs dual-level electroluminescence (EL) inspection and optimized current parameters, reducing the risk of module mismatch within a string and associated power losses. This series is designed for investors and developers seeking to minimize Balance of System (BOS) costs while achieving high power density without compromising on reliability.

About the TITAN RSM132-8-655M-675M series

6 answered

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

What warranty does the Risen TITAN RSM132-8-655M-675M series come with?
Risen Energy provides a 12-year product warranty and a 25-year linear power warranty for the TITAN RSM132-8-655M-675M modules. After 25 years, the panels are guaranteed to retain at least 84.8% of their rated output power. As a Bloomberg NEF Tier 1 manufacturer, Risen Energy offers additional assurance regarding the long-term validity of its warranty commitments.
What module efficiency does the Risen TITAN RSM132-8-675M achieve, and how does it compare?
The top variant in the series, the RSM132-8-675M, achieves a module efficiency of up to 21.7% - an excellent result for PERC technology at this large format. In practical terms, this translates to more energy per unit of roof or ground area. Compared to older polycrystalline panels, the gain of several percentage points meaningfully shortens the return-on-investment period.
Are the Risen TITAN RSM132-8-655M-675M panels suitable for a residential pitched roof?
Due to their large dimensions (2384×1303×35 mm) and weight of approximately 33.5 kg, the TITAN RSM132-8 series is primarily designed for ground-mounted systems and large industrial or commercial rooftops. On a typical residential pitched roof, these modules can be challenging to transport and install, and their large format may not fit the available surface area. For residential prosumer applications, smaller Risen modules in the 400-450 W range are generally a better fit.
How do the Risen TITAN RSM132-8-655M-675M modules perform in low-light and overcast conditions?
The PERC technology used in all 132 monocrystalline cells improves low-irradiance absorption through reflective rear-surface passivation layers. The TITAN RSM132-8 series also features a low temperature coefficient of Pmax at -0.34%/°C, limiting losses on hot days. Strong performance under diffuse light reduces energy losses during morning hours, winter months, and cloudy weather - a key factor for projects where every percentage point of annual yield matters.
What is PID and why does enhanced PID resistance matter in the Risen TITAN RSM132-8 series?
PID (Potential Induced Degradation) is a degradation mechanism triggered by high operating voltage combined with moisture, which can permanently reduce a module's power output by several percent. In the TITAN RSM132-8-655M-675M series, Risen applies enhanced PID resistance - especially important in long strings common to utility-scale PV plants operating at 1500 V system voltage and in high-humidity environments. This helps ensure that rated power output is maintained over the full 25-year warranty period.
How many Risen TITAN RSM132-8-675M modules do I need for a 50 kWp system and what total area will they cover?
At 675 W per module, a 50 kWp system requires approximately 74-75 units (50,000 W ÷ 675 W ≈ 74.1). Each module covers roughly 3.11 m² (2.384 m × 1.303 m), so the total array footprint will be approximately 230-235 m². This is a typical application for ground-mounted farms or large industrial rooftops, where the high unit power of the TITAN RSM132-8 reduces the total module count and lowers overall BoS costs.
