The Vikram Solar PARADEA series consists of bifacial glass-glass modules with a multi busbar (MBB) architecture, designed to effectively increase energy yield even under less-than-ideal conditions. Due to its bifacial operation, the panel can utilize not only direct sunlight, but also reflected light from the ground, which is particularly beneficial for installations on reflective surfaces (e.g., gravel, sand, snow). In practice, this results in better production in the morning and evening, as well as higher daily yield, without the need for over-sizing the system.

The double-glass construction provides greater resistance to environmental factors, while the solutions in the connection box and the wiring configuration support more stable operation under partial shading. This makes it a good choice for investors who are looking for lower LCOE and BOS costs, as the higher power density facilitates the optimization of the structure and wiring. PARADEA is suitable for PV farms, commercial projects, and selected rooftop installations, where durability, yield, and predictability are key.

About the PARADEA series

6 answered

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

What is the maximum power output of the Vikram Solar PARADEA panel, and where does the extra yield from bifacial technology come from?
The highest-power variants of the PARADEA series reach up to 680 Wp, thanks to a 132-cell half-cut design and multi busbar (MBB) architecture. The panel operates bifacially, capturing not only direct sunlight on the front side but also light reflected from the ground beneath the module. Depending on the albedo of the mounting surface (e.g., gravel, white roofing, snow), the additional rear-side yield can reach up to 25%, without increasing the installation footprint.
What warranty comes with Vikram Solar PARADEA panels?
The manufacturer covers the PARADEA series with a 12-year product warranty and a 30-year linear power warranty, guaranteeing at least 83.5% of nominal power after 30 years of operation, with a minimum of 98% in the first year. This is a standard typical of premium-class panels and allows investors to precisely model power degradation in PV system financial projections.
Are Vikram Solar PARADEA panels still available for purchase?
The PARADEA series has been discontinued from Vikram Solar's current production lineup and replaced by newer models in the manufacturer's portfolio. Panels may still be available through distributors as clearance or remaining stock, but when planning larger installations or expanding an existing system, it's worth confirming availability of the specific power rating and production batch with your supplier, since continuity of supply is no longer guaranteed.
How does the multi busbar (MBB) technology in PARADEA panels differ from classic designs with fewer busbars?
PERC cells with a multi busbar architecture have more thin connecting paths than older 4-5 busbar designs, shortening the current collection path and reducing resistive losses as well as the risk of microcracks. In practice, this translates into higher module efficiency, better performance under partial shading, and greater mechanical reliability, which is especially important in the glass-glass construction used in the PARADEA series.
Are PARADEA panels suitable for a residential rooftop, or only for utility-scale solar farms?
Due to their large dimensions, weight of around 39.5 kg, and power output of up to 680 Wp, the PARADEA series was designed primarily for solar farms and commercial installations, where power density per hectare and low BoS cost matter most. On sloped residential rooftops, it's less common and mainly suited to large, reinforced roof sections due to the module's size and mass.
How does the glass-glass construction of PARADEA panels affect durability and performance in harsh conditions?
A dual glass layer in place of the rear polymer backsheet increases the module's resistance to moisture ingress, cell microcracks, PID, and UV degradation, resulting in a longer lifespan and more stable power degradation over time. The temperature coefficient of power is -0.35%/°C, so the panel loses relatively little efficiency in high heat compared to cheaper glass-backsheet modules.
