It features **TOPCon n-type cell technology**, which stabilizes the module's performance from day one and helps maintain high efficiency over the long term - without the typical power loss experienced by many panels due to sunlight. It also incorporates a **split, half-cell design** and a distinctive **Twin design**, which improves the performance of the installation under partial shading and uneven sunlight exposure (e.g., caused by chimneys, skylights, or antennas). This is a solution for investors who expect predictable returns, a full black aesthetic, and easier installation design in limited spaces - with fewer modules needed to achieve the desired power output. An additional advantage is the **reinforced frame structure**, which is important in more challenging weather conditions. The series is particularly well-suited for roofs of residential homes, modern buildings, and commercial properties, where appearance and reliability are as important as energy production. ## Notable figures - Efficiency of 19.5% matches the \*\*N-type 0-400W\*\* median - Power density of 197.5 W/m² matches the \*\*N-type 0-400W\*\* median - At -0.34%/°C, loses 0.02pp more power per degree than \*\*N-type 0-400W\*\* median (-0.32%/°C) - In the top 90% for efficiency among all N-type panels ## Questions ### What is n-type TOPCon technology in the REC N-Peak 3 Black and what does it mean in practice? N-type TOPCon cells eliminate Light Induced Degradation (LID), a power loss common in p-type panels during the first weeks of operation. The REC N-Peak 3 Black produces as much power as when it left the factory and guarantees at least 92% of nameplate power after 25 years, with a warranted annual degradation of only 0.25%. This means more predictable energy yields over the entire system lifetime compared to standard PERC modules. ### What warranty does the REC N-Peak 3 Black series come with? The standard package includes a 20-year product warranty and a 25-year performance warranty. Through the REC ProTrust program, the product warranty can be extended to 25 years and also includes a labor warranty for the same period. After 25 years, the panel must retain at least 92% of its rated power. This is one of the most comprehensive warranty packages available among premium PV modules. ### Are REC N-Peak 3 Black panels bifacial and does that matter on a typical pitched roof? Yes, the REC N-Peak 3 Black is a bifacial module, meaning the rear side also generates power from reflected and diffuse light. On a typical pitched roof the bifacial gain is limited, though it increases yield on reflective surfaces such as white roofing membranes. The primary performance benefits on residential roofs come from the n-type TOPCon technology and the half-cut cell layout, which improves shading tolerance. ### How do REC N-Peak 3 Black panels perform in high summer temperatures? The REC N-Peak 3 Black has a low temperature coefficient of -0.29%/°C, meaning smaller power losses on hot days compared to typical PERC modules rated at -0.34 to -0.36%/°C. In practice this difference can translate to several additional kWh of annual production. Combined with the LID-free n-type TOPCon cells, the series maintains stable output across a wide range of real-world operating conditions. ### How many REC N-Peak 3 Black panels do I need for a 10 kWp system? At 400 Wp per module you need 25 panels to reach 10 kWp. The high unit power of the REC N-Peak 3 Black means fewer modules and less roof space compared to lower-tier 370-380 Wp panels, which would require 27-28 units for the same system size. This is especially valuable on roofs with limited usable area or where aesthetic impact needs to be minimized. ### Can the REC N-Peak 3 Black withstand heavy snow loads and strong wind? Yes, the reinforced frame of the REC N-Peak 3 Black is rated for mechanical loads up to 7000 Pa, well above the 5400 Pa required by most industry standards. This translates to solid resistance to heavy snow accumulation and high wind gusts, which is relevant in Central European climates and especially in exposed or mountainous locations. The stronger frame contributes directly to the module's long-term structural reliability. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ds-rec-n-peak-3-black-series-rev-2-1-ul-web-1dc23c04644c.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Luxor Solar LX-440M/182-108+GG](https://comparepv.com/panel/luxor-solar-lx-440m-182-108-gg) | 440 W | +50 W, cooler, +3.6 pp | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | -50 W, lighter, +3.5 pp | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +3.5 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | Lighter, +3.5 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | Lighter, +3.5 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | Lighter, +3.5 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | Lighter, +3.5 pp, +5 yr warranty | | [Jetion JT440SYK(B)](https://comparepv.com/panel/jetion-jt440syk-b) | 440 W | +50 W, cooler, +3.4 pp | | [REC REC395TP5 Black](https://comparepv.com/panel/rec-rec395tp5-black) | 395 W | +0.6 pp | | [REC REC400NP3 Black](https://comparepv.com/panel/rec-rec400np3-black) | 400 W | +10 W, +0.8 pp | | [REC REC405TP5 Black](https://comparepv.com/panel/rec-rec405tp5-black) | 405 W | +15 W, +1.1 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +120 W, cooler, +5.5 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +170 W, cooler, +5.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +115 W, cooler, +5.2 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +115 W, cooler, +5.2 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +165 W, cooler, +5.1 pp | --- Source: https://comparepv.com/panel/rec-rec390np3-black Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
