Bifacial monocrystalline solar panel JA Solar Jam66d42-570 / MB 570W

JA Solar 570W N-Type Bifacial: Maximum generation double glass, LID immunity and Tier-1 certified reliability

The deployment of efficient photovoltaic infrastructures requires components with an engineering capable of squeezing each square meter available. The solar panel JA Solar Jam66d42 / mb - 570m responding to this need by combining high purity N-Type monocrystalline wafers and a double-glass bifacial architecture, guaranteeing a productive stability, an optimized temperature coefficient and a power retention much higher than that of the market standard.

Active Bifacial Gain and Heart Cell Antangase Design

The great virtue of this module JA Solar lies in its hermetic construction with double layer of 2.0 mm glass, which enables a 80% Bifiality Degree. This technology is not limited to capturing direct radiation on its front face, but absorbs diffuse light and reflection of the soil (albedo effect) on the back. When mounting these plates on high reflectivity surfaces using structures for aluminum with calculated inclination, global energy production increases noticeably without the need to expand the physical space of the cover.

Its internal circuit is composed of 144 Average cells (6x24) interconnected by multiple busbars (MBB). Being the cells by half, the electric current that circulates by them is divided symmetrically, which reduces the losses by internal resistance and reduces the operating temperature of the module. This significantly decreases the possibility of hot spots (hot-spot) And ensure that the panel works optimally before partial shades. To efficiently manage this great continuous current injection, the system can be coupled directly with inverters hybrid of the latest generation oriented to isolated networks or with accumulation.

Resistance to aggressive atmospheres and minimized annual degradation

Thanks to the use of advanced N-Type silicon, this solar panel presents a higher immunity against the light-induced degradation phenomenon (LID) compared to traditional P-Type technologies. This guarantees a highly contained annual performance loss of only the 0.45% throughout its useful life. As a sample of its robustness, the manufacturer grants a 12-year product guarantee and a 30-year power linear generation guarantee.

Its 30 mm silver frame provides an outstanding structural stiffness, certified to support a maximum frontal static load of 5400 PA and a subsequent load of 2400 Pa. In addition, its connection box with degree of protection Ip68 it has 3 bypass diodes to protect the series of cells against overcurrent. All its exterior materials are tested to resist complex corrosive atmospheres, such as saline environments in coastal areas, agricultural environments with ammonia, sand abrasion and extreme temperature and humidity variations. If your goal is direct self-consumption without storage, this model offers perfect synchronization when connecting to high voltage rows managed by inverters networking three-phase or single-phase.

Frequently Asked Questions section (FAQ)

1. What real advantages does N-Type bifacial technology offer this panel JA Solar? Unlike conventional that only produce energy on their front face, this bifacial module takes advantage of the light reflected on the floor or rear surfaces, thanks to its double encapsulated double glass design. Being manufactured with Silicon N-Type, it eliminates almost completely the light-induced degradation (LID) from the first day, achieving an efficiency of 22.1% and guaranteeing a greater production of long-term kilowatt-hour.
2. How does Half cell technology help mitigate partial shadows losses? The panel is divided internally into two sections independent of 72 cells each. If a partial shadow caused by a fireplace, tree or dirt covers the lower half of the panel, the upper half will continue to generate energy in isolation at 100% of its capacity. This prevents the production of the whole series it completely fall, improving the annual performance of photovoltaic self-consumption.
3. Why is it important that it is designed to withstand an open circuit voltage up to 1500V? Support a system voltage up to 1500 V DC Allows rows or strings of longer lots connected to the same inverter without exceeding the security limits. This reduces the amount of grouping boxes, simplifies continuous wiring in continuous current and minimizes losses due to voltage falls in large-scale commercial and industrial facilities.
4. What resistance does this panel offer against adverse climates and heavy wind or snow loads? This photovoltaic module has a reinforced aluminum chassis of 30 mm and double tempered glass of 2.0 mm that give it an outstanding structural resistance. It is certified to withstand a frontal static pressure of 5400 PA (equivalent to strong layers of snow or wind) and a back suction of 2400 Pa. In addition, it has resistance test against corrosion by ammonia, saline fog and abrasion by Sandstorms.
5. What technical precautions should be taken when choosing the inverter for these of 570W? It is essential to review that the maximum power current (IMP of 13,35A) and the short circuit current (ISC 14,23A) of the panel are within the input ranges supported by the MPPT follower of your inverter. If the rear bifacial profit is used, the real current can be increased slightly, so it is advisable to leave a margin of thermal safety or validate the entry compatibility by consulting the specifications of our inverters networking.
