Model EIL330P72 | Polycrystalline | 72 Full-Cell Polycrystalline | Monofacial | 1500V System Voltage
The Exide Industries EIL330P72 330W polycrystalline framed solar panel is engineered for dependable power generation in demanding Indian conditions. It uses 72 polycrystalline cells to deliver a maximum power output of 330 Wp, with a panel efficiency of 17.01 percent. This module suits residential rooftops, commercial projects, and small industrial systems that require stable and predictable energy yield. A maximum system voltage of 1500 volts allows compatibility with modern high‑voltage string inverters and larger arrays.
The panel features a rugged anodized aluminium frame and 3.2 millimetre tempered glass, providing strong mechanical strength and weather resistance. With dimensions of 1956 by 992 by 35 millimetres and a weight of 22.5 kilograms, it balances easy handling with structural rigidity. Positive power tolerance from 0 to plus 1.5 percent helps ensure the installed capacity meets or exceeds the rated output. As a trusted brand from India, Exide Industries offers a well balanced solution for long term solar investments.
Reliable 330W power class: Each module delivers up to 330 Wp under standard test conditions, with a guaranteed positive tolerance from 0 to plus 1.5 percent. System designers can size strings with confidence, knowing that real output will not fall below the nameplate rating.
Efficient 72‑cell layout: The 72 cell configuration offers higher voltage at maximum power, with Vmpp of 37.76 volts. This supports longer strings, reduces cable losses, and suits typical inverter MPPT voltage windows used in Indian rooftop and ground mount projects.
Durable construction for harsh climates: Tempered glass of 3.2 millimetres and an anodized aluminium frame protect the cells from wind, rain, and temperature swings. The IP67 junction box resists dust and water ingress, which helps maintain output even in coastal or dusty environments.
Installer friendly design: Standard MC4 connectors and 1000 millimetre cable lengths simplify series and parallel connections. At 22.5 kilograms, the panel is manageable for rooftop installation teams and works with commonly available mounting structures across India.
Flexible power range options: The product family spans 325 to 335 Wp, with module efficiencies between 16.75 and 17.26 percent. This allows project developers to mix compatible wattages from the same mechanical platform while optimising for budget and available roof space.
This Exide Industries polycrystalline solar panel converts sunlight into usable direct current electricity through its 72 interconnected cells. When the panel is exposed to sunlight, photons strike the silicon wafers and free electrons, creating an electric current. The cells are wired in series within the module to reach a practical operating voltage, with a typical open circuit voltage of 45.85 volts. The resulting power output at standard test conditions reaches a maximum of 330 Wp, as defined by the specified Vmpp and Impp values.
This direct current flows through the MC4 connectors and 4 square millimetre cables into an inverter or charge controller. Grid tie inverters convert the power to alternating current that can feed household loads or export to the grid. Off grid inverters and charge controllers route the current into batteries for later use. The panel integrates bypass diodes in the IP67 junction box, which limit power losses when partial shading occurs. In a properly designed system, multiple modules are combined into strings to reach the desired array voltage and capacity.
Photovoltaic energy conversion: The 72 polycrystalline cells are made from doped silicon, which creates an internal electric field. When sunlight hits these cells, the field drives freed electrons toward the front contacts, producing direct current. This process requires no moving parts and operates silently throughout the panel life.
Series connection and power optimisation: The cells are linked in series to raise the module voltage to useful levels for inverters. At maximum power point, the panel delivers 37.76 volts and 8.75 amperes, giving 330 Wp output. Positive power tolerance ensures the real output is at or above the rated 330 Wp under standard conditions.
Protection, wiring, and system integration: The tempered glass and EVA encapsulant seal the cells against moisture and mechanical stress. The junction box houses three bypass diodes, which route current around shaded cell groups to reduce hotspot risk. Standard MC4 connectors and 1000 millimetre cables allow quick integration with strings, combiner boxes, and compatible inverters.
