For lenders and investors assessing project bankability, this can introduce added due-diligence risk compared to manufacturers with uninterrupted Tier 1 presence. - **Large module size and weight** - At 2384x1303x33 mm and 38.7 kg, the module requires reinforced mounting structures and two-person installation, which can increase logistics and installation costs compared to lighter residential-class panels with lower unit power. ## About this series The Renesola RS9-700~720NBG-E1 series are modern, **bifacial modules with a dual-glass construction**, designed for stable energy production in more challenging operating conditions. The use of **N-type cells with TOPCon technology** helps to minimize typical power losses over time and improve performance when the installation operates at higher temperatures or under diffuse light. In practice, this means more predictable operation of the PV plant and better results in locations where every percentage of production matters. Compared to the competition, they stand out due to their **high mechanical durability** and **precise MBB connection and half-cut technology**, which makes it easier to maintain high efficiency even with partial shading and variable conditions. The modules are particularly suitable for ground-mounted installations and large-scale commercial projects, where durability, safety, and long-term operation are key. A **long power warranty** also provides added value, which is important for financing and planning OPEX in larger projects. ## Notable figures - Efficiency of 22.9% matches the \*\*N-type 700-750W\*\* median - At 228.6 W/m² power density, roof space requirements are typical for \*\*N-type 700-750W\*\* panels - At -0.29%/°C, hot weather performance is typical for \*\*N-type 700-750W\*\* panels - #2536 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### What is the peak power output and module efficiency of the Renesola RS9-700~720NBG-E1? The RS9-700~720NBG-E1 series delivers up to 720 Wp peak power with module efficiency reaching 23.18%. This is an excellent result for large-format commercial panels — N-type TOPCon cells have lower recombination losses than conventional PERC, translating into more energy harvested from the same roof or ground footprint. ### What warranties come with the Renesola RS9-700~720NBG-E1, and how much power will the panels retain after 30 years? Renesola provides a 15-year product warranty on the module and a 30-year linear power warranty. After 30 years of operation, the panels are guaranteed to retain at least 87.4% of their rated power output. A long linear power warranty is a key factor when calculating LCOE and qualifying a project for external financing or insurance-backed loans. ### Is the RS9-700~720NBG-E1 a bifacial panel, and how much additional energy can the rear side generate? Yes, it is a bifacial module featuring a dual-glass construction — both sides are covered with tempered glass instead of a backsheet. The rear side harvests energy reflected from the ground surface (albedo). In practice, bifaciality can boost yield by 5–15% depending on the ground albedo coefficient: light gravel, concrete, or snow reflect significantly more than dark soil. ### At roughly 39 kg, is the Renesola RS9-700~720NBG-E1 suitable for rooftop installations or primarily for ground-mounted systems? The module weighs approximately 38.7 kg and measures 2384×1303 mm, placing it firmly in the commercial and utility-scale format category. Rooftop installation requires a robust mounting structure and professional lifting equipment. This panel is best suited for ground-mounted systems and large industrial rooftops. For residential prosumer applications, a smaller-format module from Renesola's lineup would be a more practical choice. ### How does the TOPCon technology in the RS9-700~720NBG-E1 affect performance on hot summer days? N-type TOPCon cells carry a power temperature coefficient of approximately -0.29%/°C, compared to -0.34% to -0.35%/°C typical of older PERC modules. At a module temperature of 70°C, this difference can translate into 1.5–2% higher output versus a PERC panel of the same rated power — a meaningful gain over a full year of operation in climates with hot summers. ### Is Renesola a reputable Tier 1 manufacturer, and does that matter for the RS9-700~720NBG-E1? Yes, Renesola holds Tier 1 status from independent industry analysts, reflecting a documented track record of bankable projects and long-term market presence. The company is headquartered in China and has operated globally for over two decades. Tier 1 classification simplifies project financing because banks and insurers treat modules from these manufacturers as lower-risk assets, which can reduce the cost of capital for larger PV installations. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/rs9-700-720nbg-e1-2384-1303-33-compressed-5701b9cf158d.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | -30 W, lighter, +2.3 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | -35 W, lighter, +2.1 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Cooler, lighter, +2.1 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, lighter, +2.0 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | -40 W, lighter, +1.9 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | -40 W, lighter, +1.9 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | -40 W, lighter, +1.9 pp | | [Renesola RS9-650M-E1](https://comparepv.com/panel/renesola-rs9-650m-e1) | 650 W | -60 W, lighter, -1.9 pp | | [Renesola RS9-655M-E1](https://comparepv.com/panel/renesola-rs9-655m-e1) | 655 W | -55 W, lighter, -1.8 pp | | [Renesola RS9-660M-E1](https://comparepv.com/panel/renesola-rs9-660m-e1) | 660 W | Hotter, lighter, -1.6 pp | | [Renesola RS9-665M-E1](https://comparepv.com/panel/renesola-rs9-665m-e1) | 665 W | Hotter, lighter, -1.4 pp | | [Renesola RS9-670M-E1](https://comparepv.com/panel/renesola-rs9-670m-e1) | 670 W | Hotter, lighter, -1.3 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +95 W, cooler, +2.2 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +90 W, cooler, +2.0 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +85 W, cooler, +1.9 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +80 W, cooler, +1.7 pp | --- Source: https://comparepv.com/panel/renesola-rs9-710nbg-e1 Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
