This directly cuts mounting structure, wiring, and labor costs (BoS), a critical advantage for commercial and utility-scale projects. - **Up to 21.57% Efficiency — On Par with Top Competitors** - The top-performing CE-670M variant achieves 21.57% efficiency, placing it on equal footing with the ZNShine ZXM8-TP132 (21.57%) and Techwise Summit (21.57%), and only 0.03 percentage points below the Hiwatt HW-M12/132H (21.6%). In practice, the energy yield difference between these models is negligible. - **30-Year Linear Power Output Warranty** - The manufacturer provides a 30-year performance warranty, exceeding the 25-year standard offered by many smaller suppliers. The extended warranty horizon reduces investment risk and strengthens financial models for long-term projects. - **Half-Cut + Multi-Busbar (MBB) Technology on 210 mm Cells** - The combination of half-cut cell architecture and multi-busbar (MBB) interconnection reduces resistive losses and mitigates the impact of partial shading. The standard 132-cell configuration in a 2×66 layout preserves approximately 50% of module output when the lower half is shaded. ## Cons - **No Tier 1 / Bankable Status (BNEF)** - Centro Energy does not appear on the BloombergNEF Tier 1 list (Q1 2026). For projects financed by banks or infrastructure funds, the lack of bankability may complicate or prevent access to debt financing, effectively limiting the series to equity-financed projects or smaller commercial installations. - **Product Warranty Limited to 12 Years** - The product warranty covers only 12 years, while Tier-1 manufacturers such as JA Solar, Canadian Solar, and Trina Solar standardly offer 15–25 years of product warranty coverage. Any defect arising after year 12 leaves the investor without manufacturer protection, significantly increasing operational risk over a 30-year project lifecycle. - **PERC Technology — Not N-Type TOPCon or HJT** - PERC cells exhibit higher light-induced degradation (LID) rates and a less favorable temperature coefficient than modern N-type TOPCon cells (typically -0.30%/°C vs. -0.35%/°C for PERC). In the 650–670 Wp segment, an increasing number of manufacturers are transitioning to TOPCon; opting for PERC in 2025/2026 means the series is not at the technological forefront of the market. - **No Bifacial Variant Available** - The CE-650/670M series is monofacial, whereas competitors in this power class — including the Hiwatt HW-M12/132H and ZNShine ZXM8-TP132 — offer bifacial variants capable of harvesting an additional 5–15% of energy from ground albedo. For ground-mounted installations with light-colored ground surfaces or white roofing membranes, the absence of a bifacial option represents a tangible yield loss. ## About this series The Centro Energy CE-650/655/660/665/670M series is an advanced solution for demanding investments, offering powerful unit power based on **large-format 210 mm cells**. Thanks to the use of half-cut cell technology and multi-busbar MBB connections, these modules effectively minimize resistive losses and significantly improve current flow, which translates into higher efficiency even in difficult lighting conditions. It is an ideal proposition for large-scale projects and large commercial roofs, where **lowering BOS system costs** and maximizing yield from the available area are key. These panels solve the problem of limited space, delivering more energy with fewer modules and mounting structures needed. They stand out with a **low temperature coefficient** and increased resistance to PID and LID phenomena, guaranteeing stable energy production for decades. The use of **monocrystalline PERC technology** combined with an innovative cell layout allows this series to distance itself from the competition in terms of power density and mechanical strength. By choosing these modules, investors can be certain of a faster return on investment thanks to full compatibility with modern high-current inverters and optimized operating parameters in full sun. ## Notable figures - Efficiency of 21.6% matches the \*\*PERC 650-700W\*\* median - 215.7 W/m² power density - 3.2 W/m² more than \*\*PERC 650-700W\*\* median (212.5 W/m²), more power per roof area - -0.40%/°C temperature coefficient - 0.06pp worse than \*\*PERC 650-700W\*\* median (-0.34%/°C), expect higher hot weather losses - In the top 55% for efficiency among all PERC panels ## Questions ### What warranty coverage applies to the Centro Energy CE-650/655/660/665/670M panel series? The CE-650/655/660/665/670M series comes with a 12-year product warranty covering material and workmanship defects, as well as a 30-year linear power output warranty. This means that over three decades, the modules must maintain the manufacturer's specified minimum energy yield. This represents robust protection for utility-scale projects and commercial rooftops where long-term production reliability is critical. ### What types of installations are the Centro Energy CE-670M panels best suited for? The CE-650/655/660/665/670M series is designed primarily for utility-scale projects and large commercial rooftops. The high unit power output of up to 670 Wp means fewer modules are required to reach the same system capacity, which translates into fewer mounting structures and less cabling. This directly reduces balance-of-system (BoS) costs and accelerates the return on investment. ### What is MBB technology and how does it affect the performance of the CE-670M panels? MBB (Multi-Busbar) replaces a few wide, conventional busbars with a larger number of thin busbars. In the Centro Energy CE-670M panels, this shortens the current path within each cell, reducing resistive losses and improving the capture of diffuse light. The result is higher efficiency, particularly on overcast days or at low sun angles, which increases annual energy yield. ### Do the Centro Energy CE-670M panels perform well during summer under high-temperature conditions? Yes. Thanks to PERC cell technology combined with half-cut cell architecture, the CE-650/655/660/665/670M series features a low temperature coefficient. This means that as module temperature rises, the resulting power loss is smaller than with older technologies. This is particularly significant in industrial installations where modules experience intense heating on sunny days. ### Is the CE-650/655/660/665/670M series resistant to PID? Yes, the manufacturer declares enhanced resistance to both PID (Potential Induced Degradation) and LID (Light Induced Degradation). PID is a gradual, difficult-to-reverse power loss caused by high system voltage, posing a particular risk in large-scale installations. High PID resistance ensures stable energy production throughout the full 30-year warranty period, with no unplanned power losses. ### Are the Centro Energy CE-670M panels compatible with modern inverters? Yes. The CE-650/655/660/665/670M series modules are fully compatible with modern high-current inverters. The high per-panel power output enables the design of strings at higher voltages with fewer modules, simplifying system design and reducing the number of connections. Nevertheless, it is advisable to consult with an installer before purchasing to verify inverter selection against the Isc and Voc parameters of the specific power variant. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ce-650-670m-c0175ae85d3a.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +3.6 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Cooler, lighter, +3.6 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Cooler, lighter, +3.4 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +3.4 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +30 W, cooler, +3.4 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +25 W, cooler, +3.3 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Cooler, lighter, +3.2 pp | | [Centro Energy CE-650M](https://comparepv.com/panel/centro-energy-ce-650m) | 650 W | -20 W, -0.6 pp | | [Centro Energy CE-655M](https://comparepv.com/panel/centro-energy-ce-655m) | 655 W | -15 W, -0.5 pp | | [Centro Energy CE-660M](https://comparepv.com/panel/centro-energy-ce-660m) | 660 W | -10 W, -0.3 pp | | [Centro Energy CE-665M](https://comparepv.com/panel/centro-energy-ce-665m) | 665 W | Very close match | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +135 W, cooler, +3.5 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +130 W, cooler, +3.3 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +125 W, cooler, +3.2 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +120 W, cooler, +3.0 pp | | [Trina Solar TSM-NEG21C.20Q-760](https://comparepv.com/panel/trina-solar-tsm-neg21c-20q-760) | 760 W | +90 W, cooler, +2.9 pp | --- Source: https://comparepv.com/panel/centro-energy-ce-670m Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
