The PREXOS VSMDHT.72.AAA.05 series consists of bifacial glass-to-transparent-backsheet photovoltaic modules, engineered for rooftop installations where both aesthetics and real energy yield matter. The half-cut M10 Mono PERC cells used in the module reduce resistive losses and improve panel behavior under partial shading, resulting in more stable power output throughout the year. Thanks to bifacial technology (double-sided light absorption), the panels also capture light reflected from the ground, boosting total energy yield without expanding the installation footprint. The manufacturer has focused on high corrosion resistance in demanding environmental conditions such as salt-laden air, dust, and ammonia vapors, making the series a solid choice for agricultural and coastal installations. An IP68-rated junction box with potting compound provides added electrical safety and moisture resistance. The lightweight module design simplifies mounting on roofs with limited load capacity, while a highly automated production line with multi-stage EL inspection results in lower defect rates. This makes it a strong option for investors seeking lower LCOE and predictable long-term return on investment.

About the PREXOS VSMDHT.72.AAA.05 series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

Are Vikram Solar PREXOS VSMDHT.72.AAA.05 panels still available for purchase?
No, the PREXOS VSMDHT.72.AAA.05 series has been discontinued and is no longer part of the manufacturer's active lineup. Availability is now limited to remaining distributor stock and clearance offers. If you're extending an existing installation with the same model, act quickly since inventory is limited and Vikram Solar's newer series have different dimensions and electrical parameters.
How does bifacial technology work in the PREXOS VSMDHT.72.AAA.05 module and how much extra energy does it produce?
The panel uses a dual-glass, transparent-backsheet construction, allowing the rear side of the cells to also absorb light reflected from the roof or ground. This yields additional energy without increasing the array footprint, though the actual gain depends on ground albedo, mounting tilt, and clearance height. The biggest benefits appear over bright, reflective surfaces such as light-colored roofing or gravel ground cover.
What warranty comes with the PREXOS VSMDHT.72.AAA.05 modules?
The manufacturer provides a 12-year product warranty covering material and workmanship defects, plus a 27-year linear power warranty guaranteeing a minimum performance level over time. Vikram Solar is a Tier 1 manufacturer, which adds financial credibility to the warranty and increases the likelihood it will be honored throughout the system's operating life.
Are PREXOS VSMDHT.72.AAA.05 panels suitable for agricultural or coastal installations?
Yes, the series was engineered with enhanced corrosion resistance against salt-laden air, dust, and ammonia vapors, making it well suited for farm buildings, livestock structures, and installations near the coast. The IP68-rated junction box further seals electrical connections against moisture in these demanding environments.
What is the maximum power output of PREXOS VSMDHT.72.AAA.05 panels and how do they handle partial shading?
The module reaches up to 565 Wp thanks to M10 Mono PERC half-cut cells. Splitting cells in half reduces resistive losses and means partial shading, such as from a chimney or leaves, has a smaller impact on overall panel output compared to full-size cells, resulting in steadier energy production year-round.
Are PREXOS VSMDHT.72.AAA.05 panels suitable for roofs with limited load capacity?
Yes, the module has a relatively light construction for a bifacial glass-glass panel with a transparent backsheet, making it easier to install on roofs with lower load ratings than standard glass-glass bifacial panels. Still, always verify the exact weight against the datasheet and have a designer confirm roof loading before installation.
