JA Solar 560W Bifacial N-Type: Double Glass Technology High Mechanical Resistance, 144 Average Cells and Linear Warranty 30 Years

The implementation of commercial, industrial or residential photovoltaic projects that pursue an optimal use of the space finds in the module JA Solar Jam72d40-560 / gb a first level technological exponent. This panel unifies the advantages of N-Type doping with the benefits of double glass bifacial systems, ensuring thermal stability and energy collection much higher than those of traditional plates.

Bifacial Gain of 80% and reduction of the effect of shadows by heading cell

The great differential advantage of this device JA Solar lies in its double glass architecture of 2.0 mm on each face, which gives it a 80% bifiality. Thanks to this engineering, the panel absorbs direct radiation on its front face and takes advantage of the albedo effect (light reflected by the soil, gravel or clear surfaces) through its posterior face, raising substantially the total production of the system. When interconnecting these modules on surfaces with high reflectivity by structures for aluminum with optimized inclination, it is possible to maximize this secondary energy contribution without increasing the occupied surface.

His matrix is composed of 144 Cells Holders (6x24 Configuration). By dividing the conventional cell into two symmetrical halves, the current strength that circulates through each circuit is reduced by half. This decreases internal ohmic losses due to Joule effect and softens the general working temperature of the connection box. As a result, the panel experiences a minimum risk of developing hot spots (hot-spot) and offers a greater tolerance to partial shading. To coordinate this energy flow in isolated domestic installations, it is usual to channel the combined power using inverters hybrid of the latest technological generation.

Immunity against corrosive environments, reduced degradation and Tier-1 robustness

N-TYPE doping of its silicon wafers gives the panel a natural immunity against light-induced degradation effects (LID) that suffer conventional. This translates into an annual degradation contained in just a 0.45% during your useful life, which allows the manufacturer to certify a linear power generation guarantee for 30 years and 12 years of coverage on the physical product. Its robust aluminum chassis with silver finish supports extreme mechanical loads of up to 5400 PA on its front face (snow or wind) and 2400 Pa on the rear.

The connection box has the maximum grade of sealing Ip68 and house 3 bypass diodes to protect the series of cells. In addition, its exterior components are certified to withstand the most hostile and aggressive atmospheres, including coastal salted environments, agricultural areas with ammonia presence, large friction storms and climates with extreme moisture. If your technical goal is not the accumulation but direct injection to minimize the daytime consumption of the general network, this panel is synchronized with absolute precision coupling to the residential range of our inverters networking single-phase and three-phase.

Frequently Asked Questions section (FAQ)

1. What specific advantages does a solar panel with bifacial technology in front of a conventional one? A conventional panel only generates energy through the cells on your front face exposed directly to the sun. Instead, the JA Solar 560W Bifacial has a transparent rear glass sheet that allows the cells to capture the radiation that bounces on the ground or on the adjoining surfaces (albedo effect). Depending on the type of soil on which it is installed (for example, clear gravel, white ceilings or reflective surfaces), this module can provide up to 20% or 30% extra cumulative energy throughout the year.
2. Why does the media design positively influence the rooftops prone to suffer shadows? When a partial shadow covers a section of a traditional single circuit panel, the entire row of cells or even the full module reduces its production drastically. When the panel was divided into two independent halves with 144 split cells, if a shadow affects the lower half of the module, the upper half will continue to produce energy in a totally independently independently of its individual capacity, mitigating the impact of trees, chimneys or Clouds.
3. What does it mean that it belongs to the N-Type category and how it benefits long-term degradation? Solar cells of type N (no-type) They are manufactured with phosphorus doped silicon instead of boron. This makes them immune to the phenomenon of light-induced degradation (LID) that usually redes the power of the conventional P-Type during its first hours of sun exposure. Thanks to this chemical purity, the panel JA Solar experience a very lower wear (just 0.45% per year), allowing you to guarantee by contract that will maintain excellent linear energy efficiency for 30 years.
4. Is some type of special structure required for the installation of this double glass module? Because it incorporates a double layer of 2.0 mm glass to protect both sieves from the silicon and enable bifacial function, the panel has a structural weight of 31.8 kg and a length of 2278 mm. It is essential to use robust aluminum supports that are firmly fixed to the surface and that do not project direct shadows on the back of the module, allowing a free air and light flow by reverse
5. What electrical precautions should be taken when grouping these in long series? This module is designed and certified to support high-circuit voltages up to 1500 V DC within the same string. When calculating the maximum number of that you can connect in series to your inverter, You must multiply the individual VOC (50.70 v) corrected by the winter temperature coefficient of your area. This ensures you not to exceed the tension threshold of your injection or regulation equipment on the coldest days of the year.
