Thanks to the implementation of innovative **SMBB (Super Multi Busbar)** technology, these modules are characterized by a shortened electron flow path and lower resistive losses, which significantly increases the overall efficiency of the installation. This solution is primarily dedicated to owners of buildings with complex roof architecture, where maximizing yields from a small mounting area is key. Aurora Pro panels solve the common problem of performance drops on heavily cloudy days, offering **excellent low-light characteristics**, which in the Polish climate zone guarantees real gains outside the summer peak. They are distinguished from the competition by an exceptionally **low temperature coefficient**, ensuring that the system operates stably even during extreme heat waves. The robust frame construction and tempered glass provide **above-average load resistance** to snow and wind, making this series a safe choice for years to come. Aurora Pro is a synonym for reliability for prosumers and businesses that expect state-of-the-art technologies supporting a fast return on investment and minimal operating costs of the entire photovoltaic system. ## Notable figures - At 23.2% efficiency, this panel is on par with typical \*\*TOPCon 700-750W\*\* modules - At 231.8 W/m² power density, roof space requirements are typical for \*\*TOPCon 700-750W\*\* panels - Temperature coefficient of -0.31%/°C is 0.02pp worse than \*\*TOPCon 700-750W\*\* median (-0.29%/°C) - higher losses in summer heat - Ranked #1424 out of 14005 panels for efficiency in the database ## Questions ### What warranty does the Runda Solar Aurora Pro come with? The Aurora Pro series carries a 15-year product warranty covering material and manufacturing defects, along with a 30-year linear power warranty. After 30 years of operation, the modules are guaranteed to retain at least 87.4% of their rated output. This extended warranty is made possible by N-type TOPCon cell technology, which virtually eliminates LID (light-induced degradation) and ensures stable long-term performance. ### Do the Aurora Pro 730 W panels perform well on overcast days typical of Central European climates? Yes, the Aurora Pro was engineered for the variable irradiance common in Central Europe. N-type TOPCon cells deliver excellent low-light performance, generating power even under diffuse radiation. In real-world conditions this translates into higher annual energy yields compared to standard PERC modules, particularly during spring and fall when overcast skies dominate. ### What is SMBB technology and why does it matter for the Aurora Pro? SMBB — Super Multi Busbar — replaces a few wide busbars with many ultra-thin ones, shortening the electron path to the contact and cutting resistive losses. It also distributes mechanical stress more evenly across the cell surface. For Aurora Pro owners this means a higher module efficiency rating and better resistance to microcracks during shipping and long-term thermal cycling. ### Are the Aurora Pro panels bifacial, and what practical gains can I expect? Yes, the Aurora Pro is a bifacial module, meaning both the front and rear surfaces generate power. The rear side harvests albedo radiation reflected from rooftops, ground, or snow, adding 5–15% extra yield compared to a monofacial equivalent. The gain is most pronounced on light-colored surfaces or elevated ground-mount systems, and can even benefit from snow reflection during winter months. ### How does the Aurora Pro 730 W handle high temperatures — does heat significantly cut its output? The Aurora Pro has an exceptionally low power temperature coefficient (Pmax) of approximately -0.30%/°C, a hallmark of N-type TOPCon technology. At a module surface temperature of 45°C, losses are noticeably smaller than with typical PERC panels rated at around -0.35%/°C. During summer heat waves this difference compounds into meaningfully higher daily yields. ### Are Runda Solar Aurora Pro panels suitable for complex rooftops with multiple pitches? Absolutely — the Aurora Pro was designed with architecturally complex roofs in mind. At 730 Wp per module, you need fewer panels to reach your target system size, which matters when roof space is fragmented by dormers, chimneys, or HVAC equipment. The reinforced aluminum frame and tempered glass provide above-average snow and wind load resistance, while the superior low-light response limits losses when individual roof sections fall into partial shade. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/s9-132gant-705-730w-2384x1303x35-eb103ef415c3.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Cooler, lighter, +2.0 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Cooler, lighter, +1.8 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Cooler, lighter, +1.8 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, lighter, +1.7 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | -50 W, lighter, +1.6 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | -50 W, lighter, +1.6 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | -50 W, lighter, +1.6 pp | | [Runda Solar RS705S9-132GANT](https://comparepv.com/panel/runda-solar-rs705s9-132gant) | 705 W | -15 W, -0.5 pp | | [Runda Solar RS710S9-132GANT](https://comparepv.com/panel/runda-solar-rs710s9-132gant) | 710 W | -10 W, -0.3 pp | | [Runda Solar RS715S9-132GANT](https://comparepv.com/panel/runda-solar-rs715s9-132gant) | 715 W | Very close match | | [Runda Solar RS725S9-132GANT](https://comparepv.com/panel/runda-solar-rs725s9-132gant) | 725 W | Very close match | | [Runda Solar RS730S9-132GANT](https://comparepv.com/panel/runda-solar-rs730s9-132gant) | 730 W | +10 W, +0.3 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +85 W, cooler, +1.9 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +80 W, cooler, +1.7 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +75 W, cooler, +1.6 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +70 W, cooler, +1.4 pp | --- Source: https://comparepv.com/panel/runda-solar-rs720s9-132gant 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.
