JA Solar 550W Panel | Bifacial Solar Module

JA Solar 550W Panel – Bifacial Solar Module

The JA Solar 550W Panel is a high-power bifacial solar module designed for residential, commercial and large-scale solar installations. Its bifacial technology allows the module to generate electricity from sunlight reaching the front surface while also using reflected light that reaches the rear.

The panel features monocrystalline half-cell technology and a double-glass construction. In addition, its high 550W rated output helps installers achieve larger solar-array capacities with fewer individual modules.

Actual rear-side energy gain depends on installation conditions. These include ground reflectivity, mounting height, panel spacing, shading and the surrounding environment. Therefore, bifacial performance will vary between installations.

JA Solar 550W Panel Performance

The JA Solar 550W Panel provides a rated output of 550W and a stated front-side efficiency of up to 21.3%. Its monocrystalline half-cell design helps provide reliable power generation for modern solar systems.

Furthermore, the panel supports systems with a maximum voltage of 1500V DC, according to the supplied specifications. This makes it suitable for correctly designed high-voltage solar arrays.

For example, 10 × 550W panels provide 5.5kW of rated solar-panel capacity before environmental and system losses.

Bifacial Energy Generation

Bifacial technology allows suitable reflected sunlight to reach the rear of the module. As a result, the rear surface can contribute additional energy under suitable installation conditions.

However, the stated up to 30% bifacial gain should not be treated as guaranteed additional output. Actual gain depends heavily on the installation environment.

For example, highly reflective surfaces may provide different results from dark roofing or ground surfaces.

Double-Glass Construction

The double-glass design provides additional protection for the solar cells and supports long-term outdoor use. Furthermore, the module is designed to operate across a wide temperature range.

According to the supplied information, its operating temperature range is -40°C to +85°C.

The panel also uses connectors compatible with the stated module configuration. Installers should always verify connector compatibility before combining different solar components.

Solar System Applications

The panel can form part of residential, commercial, industrial and larger solar installations. Its 550W output can help reduce the number of modules required to achieve a target solar-array capacity.

In addition, it can form part of compatible grid-tied, hybrid and battery-storage systems.

However, installers must calculate the complete PV string before installation. The array’s voltage and current must remain within the selected inverter’s MPPT and maximum PV input limits.
