They are characterized by a **wide spectral response**, which allows them to better utilize diffuse light and operate more stably under cloudy conditions, as well as in the morning and evening. The use of a **bifacial design** allows for the recovery of additional energy from reflections off the ground, which significantly improves the profitability of installations on sunny roofs and ground-mounted structures. The **multi-busbar architecture** (MBB/20 busbar) reduces losses and the risk of microcracks, and the **current matching (binning)** reduces mismatch in the string - which is important for large module arrays. The series is designed for investors who need **high power density** on a limited area - in PV farms, on building roofs, and in projects that require predictable energy production over many years. ## Notable figures - 23.7% module efficiency - 0.6pp better than the \*\*HJT 700-750W\*\* median of 23.0% - 236.6 W/m² power density - 6.4 W/m² more than \*\*HJT 700-750W\*\* median (230.2 W/m²), more power per roof area - -0.26%/°C temperature coefficient - 0.02pp worse than \*\*HJT 700-750W\*\* median (-0.24%/°C), expect higher hot weather losses - At 39.5 kg, this panel is 1.2 kg heavier than the \*\*HJT 700-750W\*\* median (38.3 kg) - more demanding for installation crews - 90% bifaciality enables rear-side power generation, boosting yield by 4-14% on reflective surfaces ## Questions ### How does HJT cell technology in the SURYAVA VSMDH.66.AAA.05 panels differ from standard PERC or TOPCon cells? HJT (Heterojunction) sandwiches a crystalline silicon wafer between thin layers of amorphous silicon, delivering higher efficiency (up to 23.66%) and a broader spectral response than PERC or TOPCon. This lets the panel capture more diffuse light, so it performs more consistently in cloudy conditions and during early morning or late afternoon hours. HJT also has a lower power temperature coefficient, meaning less output loss during hot weather compared to conventional cell technologies. ### How much extra energy can the bifacial design of the SURYAVA VSMDH.66 series actually deliver? The bifacial construction captures additional energy from light reflected off the ground onto the rear side of the module. On highly reflective surfaces (white gravel, roofing membrane, snow), this typically adds a few to over ten percent extra yield compared to a monofacial panel of the same front-side power rating. The gain is largest on ground-mount farms and light-colored industrial roofs, and smaller when the module sits close to a dark surface. ### What warranty comes with the Vikram Solar SURYAVA VSMDH.66.AAA.05 panels? The manufacturer offers a 12-year product warranty and a 30-year linear power warranty, guaranteeing around 87.98% of nominal output at year 30. Vikram Solar is a Tier 1 manufacturer based in India, which adds confidence that the warranty will remain enforceable throughout the system's operating life. ### Are the SURYAVA VSMDH.66.AAA.05 panels suitable for a solar farm or industrial rooftop installation? Yes, the series is built for large-scale projects - power output up to 735 Wp per module delivers high power density on limited surface area, reducing the panel count and cabling needed. Current binning minimizes string mismatch losses, while the bifacial design further boosts yield on light-colored roofs and ground-mount farms. ### How do the HJT cells in the SURYAVA series perform under high summer temperatures? HJT technology has a lower power temperature coefficient than conventional PERC cells, meaning output declines more slowly as panel temperature rises. In practice, this translates into better energy yield on hot, sunny days compared to standard modules, particularly for rooftop mounting where panels tend to run hotter. ### What does the 20-busbar (MBB) architecture and current binning mean for a large SURYAVA installation? MBB architecture with 20 busbars increases the number of current paths between cells, reducing resistive losses and the impact of micro-cracks. Current binning groups cells with matched current output within the same module. In large strings, this limits mismatch losses, so the whole array performs closer to the sum of individual panel outputs instead of being capped by the weakest cell. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/SURYAVA-G12-710-735W-132-CELLS1-9f3fa655ed55.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | -35 W, lighter, +1.3 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | -40 W, lighter, +1.2 pp | | [AIKO AIKO-A690-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a690-mae78dw) | 690 W | -45 W, lighter, +1.0 pp | | [AIKO AIKO-A685-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a685-mae78dw) | 685 W | -50 W, lighter, +0.8 pp | | [Trina Solar TSM-NEG21C.20Q-760](https://comparepv.com/panel/trina-solar-tsm-neg21c-20q-760) | 760 W | +25 W, lighter, +0.8 pp | | [AIKO AIKO-A785-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a785-grh78dw) | 785 W | +50 W, +0.7 pp | | [Gokin GK-4-78HGBD-780M](https://comparepv.com/panel/gokin-gk-4-78hgbd-780m) | 780 W | +45 W, +0.6 pp | | [AIKO AIKO-A780-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a780-grh78dw) | 780 W | +45 W, +0.6 pp | | [Jetion JT755SLk(B)](https://comparepv.com/panel/jetion-jt755slk-b) | 755 W | Cooler, lighter, +0.6 pp | | [Trina Solar TSM-NEG21C.20Q-755](https://comparepv.com/panel/trina-solar-tsm-neg21c-20q-755) | 755 W | +20 W, lighter, +0.6 pp | | [Vikram Solar PARADEA VSMDH.66.AAA.05-655](https://comparepv.com/panel/vikram-solar-paradea-vsmdh-66-aaa-05-655) | 655 W | -80 W, hotter, -2.6 pp | | [Vikram Solar PARADEA VSMDH.66.AAA.05-660](https://comparepv.com/panel/vikram-solar-paradea-vsmdh-66-aaa-05-660) | 660 W | -75 W, hotter, -2.4 pp | | [Vikram Solar PARADEA VSMDH.66.AAA.05-665](https://comparepv.com/panel/vikram-solar-paradea-vsmdh-66-aaa-05-665) | 665 W | -70 W, hotter, -2.2 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +70 W, +1.4 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +65 W, +1.2 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +60 W, +1.1 pp | --- Source: https://comparepv.com/panel/vikram-solar-suryava-vsmdh-66-735-05 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.
