Solar Panel Longi Mono Perc 555WP

LONGI LR5-72HPH-555M: Bifacial innovation and optimized 555WP power

Designing profitable solar energy systems involves selecting components capable of taking advantage of each available sunbeam, including the floor reflected or adjoining surfaces. The photovoltaic panel 555WP Longi It has been developed to lead this segment of high power, integrating in a single chassis the best innovations in monocrystalline silicon type P of one of the world's largest manufacturers of the world.

Advanced Bifial Technology and Anti-Shadow Structure

The great differential advantage of this solar plate in front of other models of the series is its bifacial capacity. In addition to absorbing direct sunlight on its front face, the panel is designed to capture the albedo effect (radiation reflected by clear surfaces, concrete covers, gravel or soil), which can significantly increase the final energy production By square meter depending on the assembly conditions.

On Tienda Solar We value the constant performance under any circumstance. Therefore, this model has an architecture 144 Cells. By dividing the internal circuit into two independent sections (72 symmetric above and 72 below), the operating current decreases, drastically reducing internal heat electric losses. In case partial shades due to leaves, accumulated dirt or clouds, the panel continues to operate at half capacity independently without penalizing the performance of the complete string.

Low Lid immunity against degradation and mechanical robustness

The heart of Longi 555WP benefits from a process of gallium dock, a premium manufacturing technique that eradicates the initial chemical wear caused by contact with oxygen when exposed to the sun. This protection (Low Lid technology) ensures a minimum initial degradation in the first year. Likewise, its high purity materials guarantee excellent immunity against the PID phenomenon (degradation by voltage difference), ideal for installations connected in series with inverters up to 1500V maximum tension of the system.

At the structural level, it has a 2 mm high-transmissive tempered glass front glass mounted on a silver anodized silver thick color aluminum frame. This compact structure gives you the ability to tolerate severe mechanical loads: it supports static snow pressures of up to 5400 PA and dynamic wind thrusts of up to 2400 Pa. Its certified won connection box Ip68 It has 3 bypass diodes to shield the electronics against micro-cracks and hot spots (Hot-Spots).

Frequently Asked Questions (FAQ)

1. What real benefit does this LONGI panel from 555W be bifacial? Unlike Traditional single-phase, the bifacial module has an active rear face capable of transforming the light reflected by the environment into electricity. If installed on surfaces with high reflection index (such as white covers, light sand or high soil structures), you can generate an extra clean energy above the 555W nominal of your frontal technical sheet.
2. Is this 555W panel compatible with microinvestors or inverters residential? Yes, it is fully compatible. Due to its electrical parameters (maximum power voltage of 42.10V and maximum power current of 13.19a), it fits perfectly within the operating ranges of the vast majority of inverters network power plants (as Huawei, Fronius or Kostal). However, due to its large size and bifacial capacity, it is important to verify that the ranges of intensity of the inverter They admit their short circuit current (ISC 14.04a).
3. Why is the least length of busbars in the cells? When cutting the cell in half, the path that electrons should be traversed through Busbar decreases noticeably. This reduces the internal resistance of the component, minimizes unwanted recombination of electrons and decreases the loss of power by heating, translating into a colder solar plate and more efficiently in warm climates.
4. What kind of maintenance does this photovoltaic module require? Maintenance is minimal but important. To preserve its efficiency of 21.5%, it is enough to clean the glass surface with water and a soft cloth when dust, pollen or bird droppings accumulate. Being a bifacial model, it is advisable to keep the lower area of the structure to ensure that the rear face receives the maximum reflection of light as possible.
