Model EA 355W | Bifacial PERC | 144 Half-Cell Polycrystalline | Bifacial | 1500V System Voltage
The Energy America EA 355W bifacial polycrystalline PERC solar panel is designed for reliable long term output on modern rooftop and ground mounted systems. This high performance module delivers up to 355 watts of front side power, with panel efficiency reaching 17.89 percent under standard test conditions. Its bifacial PERC architecture and polycrystalline cells work together to capture more sunlight and convert it into electricity with impressive stability. The module suits residential, commercial and light industrial projects that require dependable power density in a slim 30 millimeter frame. With a 144 half cell layout, robust IP68 junction box and 1500 volt system rating, the EA 355W panel integrates easily into contemporary string or central inverter designs. Customers can expect durable construction, strong energy yield and a competitive warranty package that supports long term investment returns.
High power density in a compact footprint: With a rated output of 355 watts, this module delivers strong energy yield from a 2000 by 992 millimeter frame, ideal where roof space is limited.
Bifacial PERC technology for enhanced harvest: Bifacial PERC cells can convert light from both the front and rear sides, which supports higher kWh production on reflective surfaces and optimized mounting structures.
Stable performance with low degradation: The panel is backed by a power warranty with only 0.57 percent annual degradation, retaining 97.5 percent at year one and 83 percent after 30 years.
Robust design for demanding environments: An IP68 rated junction box, tempered glass with anti reflection coating and a wide operating temperature range from minus 40 to 85 degrees Celsius support reliable operation outdoors.
Flexible integration with modern systems: The 1500 volt system rating and 15 amp series fuse compatibility make the module suitable for long strings, reducing balance of system costs and simplifying design.
Lightweight yet durable construction: At 25.5 kilograms, the panel strikes a balance between rigidity and handling ease, which supports safe installation on rooftops and ground racks.
The EA 355W bifacial polycrystalline PERC solar panel converts sunlight into usable direct current power through a combination of efficient cell design and durable packaging. Sunlight strikes the polycrystalline cells arranged in a 144 half cell matrix, where photons are absorbed and electrons released to create an electrical current. Because the module uses bifacial PERC technology, light reaching the rear side can also be harvested when reflected from the roof, ground or surrounding surfaces. The anti reflection coated tempered glass improves light transmission on the front, while the encapsulant layers protect cells from moisture and mechanical stress. The generated current flows through integrated busbars into the junction box, where bypass diodes help minimize power loss in partial shading conditions. From there, the DC output is routed through connectors and strings toward an inverter, which converts the power into alternating current suitable for homes or businesses. The design has been optimized to maintain performance over decades within the specified temperature and voltage limits.
Bifacial energy capture: The panel features bifacial architecture, allowing both sides to participate in power generation when exposed to light. Light reflected from bright roof surfaces, concrete or ground coverings can reach the rear side, boosting overall energy yield compared to a similar monofacial module. This makes the panel especially effective in elevated mounts, carports and arrays above reflective surfaces.
PERC cell enhancement: Passivated emitter and rear cell technology improves carrier collection within each polycrystalline cell. A passivation layer on the rear surface reduces recombination losses and reflects unabsorbed light back into the cell for a second chance at conversion. This process increases efficiency and helps the module achieve a strong 17.89 percent front side rating within a standard sized format.
Half cell string configuration: The 144 half cell layout effectively splits the module into multiple shorter strings, which reduces series resistance and improves shade tolerance. Lower resistive losses translate into higher output at the same irradiance compared to full cell designs. When sections of the module are shaded, integrated diodes and the half cell structure help keep unaffected areas producing power more efficiently.
Thermal and electrical protection: The module is engineered for reliable operation between minus 40 and 85 degrees Celsius, with defined temperature coefficients for power, voltage and current. As temperatures rise, output voltage naturally drops, and the specified coefficients allow system designers to model this behavior accurately. An IP68 junction box with three diodes protects against moisture ingress and helps manage hot spots during partial shading, preserving long term reliability.
