A key advantage of this line is the combination of advanced TOPCon architecture with bifaciality, allowing for active energy generation not only from direct radiation but also from light reflected from the ground. This solves the problem of limited installation space, offering a significantly higher yield per square meter compared to traditional monofacial panels. The applied **bifacial technology with a high bifaciality factor** makes these panels unrivaled in professional ground-mounted installations and on flat roofs with light-colored surfaces. They stand out for their exceptional resistance to LID and PID degradation, which directly translates into decades of stable operation. For the investor, this means a **lower LCOE cost of energy** and a faster return on investment thanks to excellent performance in low-light conditions. This series is dedicated to demanding commercial systems and solar farms where maximizing profit is the priority. By choosing these modules, you gain an **optimized temperature characteristic** that outperforms standard market solutions, ensuring the highest efficiency even on hot days. ## Notable figures - At 23.1% efficiency, this panel is 0.7pp above typical \*\*TOPCon 550-600W\*\* modules (median: 22.4%) - 231.4 W/m² power density - 7.0 W/m² more than \*\*TOPCon 550-600W\*\* median (224.4 W/m²), more power per roof area - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 550-600W\*\* median - 29.5 kg weight - 1.7 kg lighter than \*\*TOPCon 550-600W\*\* median (31.2 kg), reducing installation effort - Ranked #1509 out of 14005 panels for efficiency in the database ## Questions ### How do Sunpro 210R TOPCon BIFACIAL panels differ from standard monofacial modules? The key difference is the bifacial design, which allows the module to generate energy from its rear side as well, using light reflected off the ground or roof surface. Combined with TOPCon technology and rectangular N-type cells, this delivers a higher energy yield per square meter than classic monofacial panels, with power output reaching up to 575 Wp. ### What warranty comes with Sunpro 210R TOPCon BIFACIAL panels? The manufacturer provides a 25-year product warranty and a 30-year linear power output warranty. This means the panel retains a high percentage of its rated power for three decades, which is an important factor when calculating the profitability of a commercial installation or PV farm. ### Are Sunpro 210R bifacial panels suitable for flat roof installations? Yes, the 210R TOPCon BIFACIAL series is particularly well suited for flat roof installations with light-colored surfaces, such as gravel or membrane roofing, since a bright surface increases the amount of light reflected onto the panel's rear side. A high bifaciality factor allows for a real boost in energy production compared to monofacial modules under these conditions. ### Does TOPCon technology in Sunpro 210R panels improve performance in low-light conditions? Yes, the N-type cells used in TOPCon technology respond better to low irradiance levels than older P-type cells. As a result, Sunpro 210R panels generate more energy in the early morning, evening, and on overcast days, directly improving the annual yield of the installation. ### Are Sunpro 210R TOPCon BIFACIAL panels resistant to LID and PID degradation? Yes, this series is engineered for high resistance to both light-induced degradation (LID) and potential-induced degradation (PID). This keeps power loss over time minimal, allowing the installation to maintain stable performance for decades, which directly translates into a lower levelized cost of electricity (LCOE). ### What type of installations are Sunpro 210R TOPCon BIFACIAL panels best suited for? This series is primarily designed for professional ground-mount installations and large-scale commercial systems, including solar farms, where maximizing yield per square meter is the priority. Sunpro Power is a Tier 1 manufacturer, which adds further confidence for long-term investment in large-scale PV projects. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/topcon-spdgxxx-n120r12-560-575w-30mm-32f71de74875.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +1.7 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +1.5 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, lighter, +1.3 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Cooler, lighter, +1.3 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | Cooler, lighter, +1.3 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | -25 W, cooler, +1.1 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | Cooler, lighter, +1.1 pp | | [Sunpro Power SPDG560-N120R12](https://comparepv.com/panel/sunpro-spdg560-n120r12) | 560 W | -10 W, -0.4 pp | | [Sunpro Power SPDG565-N120R12](https://comparepv.com/panel/sunpro-spdg565-n120r12) | 565 W | Very close match | | [Sunpro Power SPDG575-N120R12](https://comparepv.com/panel/sunpro-spdg575-n120r12) | 575 W | +0.2 pp | | [Gamko New Energy GKA120N-PRO-590W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-590w) | 590 W | +20 W, lighter, +0.7 pp | | [Gamko New Energy GKA120N-PRO-585W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-585w) | 585 W | +15 W, lighter, +0.5 pp | | [Bisol BGO 580](https://comparepv.com/panel/bisol-bgo-580) | 580 W | Cooler, lighter, +0.4 pp | | [Gamko New Energy GKA120N-PRO-580W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-580w) | 580 W | +10 W, lighter, +0.3 pp | --- Source: https://comparepv.com/panel/sunpro-spdg570-n120r12 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.
