REC Solar REC590AA Pro MG 590W HJT Bifacial Monocrystalline Solar Panel
Model REC590AA Pro MG | HJT Bifacial | 120 Half-Cut Monocrystalline Cells | Bifacial | 1500 V System Voltage
Product Overview
The REC Solar REC590AA Pro MG 590W HJT bifacial monocrystalline solar panel is designed for demanding commercial and industrial sites. This high power module delivers up to 590 Wp with a front side efficiency of 20.8 percent, giving strong production from a compact footprint. Advanced heterojunction cells and bifacial architecture allow energy to be harvested from both sides of the module when reflective surfaces are used. The panel is built with robust dual 2 mm solar glass, an anodized aluminum frame, and an IP68 junction box for long term reliability. A 30 year product and performance warranty supports dependable output with only 0.31 percent annual degradation after the first year. With a 1500 volt system rating and 35 amp series fuse rating, this panel integrates easily into large scale arrays and optimized designs. Installers and asset owners gain a bankable solution that supports high yield, low maintenance solar power generation over decades.
Key Benefits
High power density for limited roof space: Up to 590 Wp from a 2175 x 1305 mm footprint allows more energy to be produced per module. This helps maximize system output where roof or ground space is constrained.
Bifacial HJT cells boost energy yield: Bifacial heterojunction cells capture light from both the front and rear surfaces. When mounted above bright or reflective surfaces, additional backside generation improves annual kWh production.
Superior temperature performance: A low temperature coefficient of Pmax at -0.24 percent per degree Celsius helps preserve output on hot days. Systems can maintain strong production even during high summer temperatures.
Long term reliability with 30 year coverage: A 30 year product warranty and 30 year performance guarantee provide strong assurance. The panel is warranted to retain 90.75 percent of initial power after three decades of operation.
Robust mechanical design for harsh sites: Dual 2 mm glass, anodized aluminum framing, and IP68 junction boxes support use in demanding climates. High system voltage capability improves string design flexibility and reduces balance of system costs.
How It Works
This REC heterojunction bifacial solar panel converts sunlight into usable electrical energy using advanced cell technology. When sunlight hits the 120 half cut monocrystalline cells, photons are absorbed and release electrons within the silicon layers. Heterojunction construction combines crystalline silicon with thin film layers to reduce losses and increase power conversion efficiency. Because the module is bifacial, the rear glass also collects reflected light from the ground or roof surface beneath the array. The resulting direct current power flows through optimized busbars to the IP68 junction box and integrated cables. From there, DC power is routed to a compatible inverter, which converts it to alternating current suitable for on site loads or export to the grid. Throughout this process, the panel operates within a wide temperature range, while low thermal coefficients help maintain output stability.
Front side light capture and conversion: The front 2 mm solar glass uses an anti reflection coating to admit more light into the cells. Photons striking the monocrystalline silicon generate charge carriers, which are collected and directed into the module’s electrical circuit with reduced resistive losses.
Rear side bifacial gain: The rear glass layer with a white grid is engineered to capture diffuse and reflected light. When installed above bright ground coverings, roofing membranes, or light colored ballast, additional irradiance reaches the rear cells, increasing total energy yield without extra roof area.
System integration and protection: Three bypass diodes in the junction box help reduce mismatch losses under partial shading. Factory fitted 4 mm² solar cables and certified connectors support secure, low resistance connections to string wiring and inverters.
