Avant-garde engineering: the heart of the modules JA Solar

The competitive advantage of JA Solar resides in its model vertical integration. By controlling each stage of the production process, the company ensures total traceability and quality standards that exceed international regulations. This technical capacity allows the democratization of high efficiency technologies, offering modules that reach yields greater than 22% with minimal annual degradation.

The massive implementation of technology PERC (Passivated Emitter Rear Cell) has redefined the solar collection standard. By incorporating a reflective treatment into the back of the cell, the photons that go through the wafer is being recovered without being absorbed, returning them to the cell for a second electric conversion opportunity. This process, added to the technology of Cell heading (Half-Cut), allows to reduce losses due to internal resistance and drastically improve panel behavior to situations of partial shading or high temperatures.

Technical advantages and operational value

• Deep Blue 3.0 Technology: This series represents the perfect balance between power and manageability. With powers that reach up to 580W, these modules optimize the LCOE (level of energy) by reducing the number of structures and wiring necessary by watt installed.

• Reduction of hot spots (Hot Spots): The media design reduces the current that circulates through each driver, minimizing the risk of hot spots and prolonging the useful life of the laminate.

• Bifacial performance: JA Solar He has led the adaptation of PERC technology to bifacial modules, allowing radiation by both panel sides and increasing total production up to 25% depending on the soil albedo.

• Long-term guarantees: The products have a solid support of 12 years of product warranty and 25 years of linear production guarantee, ensuring that the system maintains a predictable generation capacity throughout its useful life.

Featured technical specifications

• Module efficiency: Values superior to 21-22%, Locating on the tall band of the Tier 1 market.

• Optimized temperature coefficient: Excellent behavior in warm climates, maintaining production even when the temperature of the cell increases.

• Mechanical resistance: Certificates to withstand wind loads up 2400 pa and snow loads up 5400 pa.

• Low degradation: Integrated technologies to mitigate the effects of Lid (Light Induced Degradation) and PID (Potential Induced Degradation).

Frequently Asked Questions (FAQ) on JA Solar

1. What does it mean that JA Solar Be a Tier 1 manufacturer? The Tier 1 classification indicates that the company is financially solvent, it has its own manufacture (not subcontract) and has a high level of R & D investment. This offers the customer the assurance that the brand will respond by its guarantees during the 25 years of product life.
2. How does Half-Cut technology benefit my installation? By dividing the cells in half, the current that circulates by them is reduced. This decreases heat losses (Joule effect) and allows, if one half of the panel is in shadow, the other half continues to produce 100% energy, something vital in residential roofs with obstacles.
3. What is the difference between a facial monkey and a bifacial panel of JA Solar? The monofacial panels capture energy only by the front face. Bifacials have an active rear face that takes the light reflected on the ground or white surfaces. They are ideal for floor installations or covered with high reflectivity.
4. Are the panels compatible JA Solar with any inverter? Yes, provided that the voltage ranges (V) and current (A) are respected inverter. The panels of the Deep Blue series, for example, have optimized open circuit voltages to allow longer and efficient strings.
