Model EX155P-36 | Polycrystalline Silicon | 36 Full-Cell | Monofacial | 1500V System Voltage
The Exiom Solution EX155P-36 155W polycrystalline solar panel is engineered as a compact, high‑performance module for small off‑grid and residential systems. This Spanish designed panel combines 36 high‑efficiency polycrystalline cells with robust mechanical construction, making it ideal for 12V battery charging, RV and boat installations, rural lighting, and small commercial projects. A wide power range from 140W to 155W allows flexible system design while keeping footprint and weight under control. With module efficiency up to 18 percent and an operating temperature range from minus 40 to 85 degrees Celsius, reliable energy is delivered in diverse climates. The linear performance warranty helps protect long term output, while the 1500V system rating supports modern string configurations with fewer balance‑of‑system components.
Optimized for 12V systems: With a maximum power voltage around 18.35 volts, this module matches common 12V charge controllers and battery banks. System sizing and wiring remain simple for cabins, boats, and RV applications.
High efficiency in a compact footprint: Module efficiency up to 18 percent allows more energy from limited roof or rack space. This is valuable where surface area is restricted, such as vehicle roofs and small structures.
Durable construction for harsh sites: High transmittance 3.2 millimeter glass and a robust frame offer resistance to mechanical loads up to 5400 pascals. The operating temperature range from minus 40 to plus 85 degrees Celsius supports challenging environments.
Reliable long term energy yield: A total degradation rate of only 0.67 percent per year is specified. Output is warranted at 90 percent for 12 years and 80 percent for 30 years, which supports confident lifetime planning.
Lightweight and easy to handle: At 12 kilograms, the panel is simple to lift, carry, and mount by one or two installers. This saves labor on rooftops, in remote areas, and on mobile applications where access can be difficult.
The EX155P-36 converts sunlight into usable DC electricity through its 36 interconnected polycrystalline cells. When the module is exposed to solar radiation, photons strike the silicon junctions and create an electric field. This drives electrons through the cell circuitry and generates current at the panel terminals. The module operates most efficiently near its maximum power point, defined by the specified voltage and current values. In practical systems the panel is connected to a charge controller, which manages battery charging, or to an inverter in larger arrays. The high system voltage rating supports long strings in grid‑tied systems, while the electrical characteristics remain well suited for standalone 12V configurations.
Sunlight capture and DC generation: Polycrystalline silicon cells absorb incoming light and convert it into direct current. The module produces up to 8.45 amperes at 18.35 volts under standard test conditions, delivering 155 watts of rated power. Even in moderate light, current is still generated and can support trickle charging.
Power regulation and battery charging: The panel output is usually routed to a PWM or MPPT charge controller. That device holds the battery voltage within safe limits while drawing power near the panel’s maximum power point. The electrical profile suits 12V lead‑acid and lithium batteries in off‑grid systems.
System integration and safety: A maximum system voltage of 1500 volts allows multiple modules in series for higher power arrays. The 15 ampere series fuse rating supports secure over‑current protection within string design. Combined with quality junction boxes and wiring, this ensures stable operation across the module lifetime.
