The Vikram Solar PREXOS series consists of technologically advanced modules utilizing half-cut cell technology, which significantly reduces energy losses resulting from internal resistance and periodic shading. Thanks to the use of an innovative monocrystalline bifacial cell design, these panels generate electricity not only from direct sunlight but also from radiation reflected from the ground, making them an ideal solution for large ground-mounted farms and commercial installations. The use of multi-busbar connections minimizes the risk of micro-cracks and improves charge flow, which directly translates into higher efficiency in low sunlight conditions. The PREXOS series effectively solves the problem of limited installation space by offering impressive power density, which allows for significant optimization of system and cabling costs. What distinguishes these modules from the competition is their exceptional resistance to LID and LeTID degradation, as well as a reinforced frame prepared for extreme mechanical loads. By choosing the PREXOS series, investors receive a guarantee of stable energy yields over a very long time horizon, making it a solution dedicated to the most demanding photovoltaic projects focusing on reliability and a fast return on investment.

Common questions

6 answered
Is the Vikram Solar PREXOS series still available for purchase?
The manufacturer has discontinued the PREXOS series, replacing it in the current lineup with newer solutions such as the Paradea series. PREXOS modules may still be found through distributors selling remaining warehouse stock, but availability is limited and shrinking over time. Buyers should confirm stock of the specific power rating and the validity of the manufacturer warranty before purchasing.
What are the benefits of the half-cut cell technology used in PREXOS?
Splitting each cell in half reduces internal resistance and resistive losses, resulting in higher energy yield, especially under partial shading such as from a chimney or antenna. The smaller cell segments are also more resistant to microcracks, improving the panel's durability during handling, transport, and installation in demanding conditions.
What warranty does Vikram Solar offer on the PREXOS series?
The PREXOS series comes with a 12-year product warranty covering material and workmanship defects, plus a 27-year linear power warranty guaranteeing a defined percentage of initial output throughout that period. This is one of the longer warranty periods offered by tier-1 manufacturers, which matters when calculating return on investment for larger installations.
Do PREXOS bifacial panels make sense for ground-mounted installations?
Yes, the bifacial design with monocrystalline PERC cells captures additional energy from light reflected off the ground, which is especially beneficial for ground-mounted systems on light, reflective surfaces such as gravel or white membrane. This extra rear-side energy gain can meaningfully increase total output compared to monofacial modules in a solar farm.
What type of installation suits a 680 Wp PREXOS panel?
The 680 Wp output and high power density make the PREXOS series well suited to large commercial installations and solar farms, where fewer panels are needed to reach a target capacity, reducing costs for mounting structures, cabling, and installation labor. It's a design optimized for limited roof or ground space while maintaining high performance.
Is Vikram Solar a reliable manufacturer, and where is it based?
Vikram Solar is an Indian solar module manufacturer classified as a tier-1 supplier, indicating recognized financial stability and bankability for projects using its panels. The PREXOS series was also known for strong resistance to LID and LeTID degradation and a reinforced frame, making it a trusted choice for investors seeking stable energy yields over the long term.
