These are **bifacial** modules that can utilize light from both sides - this makes it easier to increase power generation on bright roofs, carports, or ground-mounted structures with appropriate backing. The use of **N-type TOPCon** cells helps to minimize losses and maintain high efficiency over time, which is particularly important for projects focused on long-term returns. The **dual glass** variant increases resistance to environmental conditions and makes it easier to maintain performance in demanding locations. In addition, the **half-cut** technology and multi-wire connection (MBB) of cells support better performance under partial shading and reduce the risk of micro-cracks. This is a good choice for businesses and homeowners who want to maximize self-consumption or power generation per square meter, while also expecting a **long-term power warranty** and predictable operation. ## Notable figures - Module efficiency of 21.8% is 0.7pp below average for \*\*N-type 450-500W\*\* panels (median: 22.5%) - At 217.8 W/m², this panel generates 7.4 W/m² less per unit area than \*\*N-type 450-500W\*\* median (225.2 W/m²) - At -0.29%/°C, hot weather performance is typical for \*\*N-type 450-500W\*\* panels - Weight of 28.0 kg is 4.3 kg above \*\*N-type 450-500W\*\* median (23.7 kg) - verify structural support - Bifacial design (70% factor) captures reflected light - adds 4-10% yield on ground-mount or white roof ## Questions ### Is the Renesola RS4-470~490NXG-E1 series still available for purchase? The RS4-470~490NXG-E1 series has been discontinued and is no longer offered as a new product through regular distribution channels. Limited stock may still be found at some distributors, but it is not advisable to base a larger installation on these panels. Renesola has replaced this series with newer models built on the same N-type TOPCon technology. ### What warranty does the Renesola RS4-470~490NXG-E1 come with? Renesola provides a 15-year product warranty covering materials and workmanship, along with a 30-year linear power output warranty. After 30 years, the module is expected to retain at least 87.4% of its rated power under standard test conditions. The 30-year power guarantee is among the longest on the market and makes this series suitable for projects with extended payback horizons. ### What is N-type TOPCon technology and why does it matter for the RS4-490NXG-E1 series? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that minimizes carrier recombination at the silicon-metal contact interface. In practice, it delivers higher conversion efficiency, a lower temperature coefficient of power loss, and slower long-term degradation compared to PERC cells. In the RS4-470~490NXG-E1 series, this translates to more stable energy production throughout the 30-year warranty period. ### Is the RS4-490NXG-E1 bifacial, and how much extra energy does the rear side generate? Yes, the RS4-470~490NXG-E1 is a bifacial dual glass module. The rear side captures light reflected from the ground, rooftop, or surrounding surfaces, potentially boosting real-world energy yield by 5-15% depending on the albedo of the surface below. The best results come from bright substrates such as gravel fields, white membranes, snow, or light-colored roofing. On a typical dark rooftop, the bifacial gain will be more modest. ### Are the RS4-470~490NXG-E1 dual glass modules heavier and harder to install than standard panels? Dual glass panels are slightly heavier than those with a standard backsheet, typically by 1-2 kg. They also require adequate clearance beneath the module so that light can reach the rear surface. Installation itself is not fundamentally more complex, but the installer must follow the manufacturer's clamping specifications and minimum ground clearance requirements, especially on ground-mounted racking systems. ### Which inverters are compatible with the Renesola RS4-490NXG-E1, and is special sizing required? The RS4-470~490NXG-E1 modules, rated up to 490 Wp, are compatible with inverters from major brands such as SMA, Fronius, Huawei, SolarEdge, and Growatt, provided the Voc and Isc values fall within the inverter's DC input specifications. The high per-module power output requires careful string sizing to ensure the total string voltage stays within the inverter's MPPT input range. A system designer or the inverter manufacturer's string calculator should be used to verify compatibility. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/rs4-470-490nxg-e1-1903-1134-30-fd0cdd8e7385.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +3.2 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +3.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +2.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +2.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +2.7 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +30 W, lighter, +2.7 pp | | [Renesola RS4-475N-E1](https://comparepv.com/panel/renesola-rs4-475n-e1) | 475 W | Lighter, +0.2 pp | | [Renesola RS4-480N-E1](https://comparepv.com/panel/renesola-rs4-480n-e1) | 480 W | +10 W, lighter, +0.5 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +90 W, lighter, +3.0 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +85 W, lighter, +2.8 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +80 W, lighter, +2.6 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +70 W, lighter, +2.6 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +70 W, lighter, +2.6 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +75 W, cooler, +2.5 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | +75 W, lighter, +2.4 pp | --- Source: https://comparepv.com/panel/renesola-rs4-470nxg-e1 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
