Talesun Solar 590W Hail-Resistant Solar Panel 144 Cell Bifacial TM7G72M-590 Wholesale 36 panels per pallet

The Talesun Solar TM7G72M-590 is a 590W bifacial solar panel built on N-type monocrystalline technology, designed for residential and commercial installations where maximum yield and long-term durability are the priority. As part of the BIPRO series, it combines dual-glass construction with 16-busbar half-cut cell architecture to deliver industry-leading output and exceptional environmental resilience.

Note: The TM7G72M features a thickened 3.2mm front glass layer specifically engineered for hail-prone regions. It is certified to withstand Φ55mm hailstones at 33.9 m/s (75.8 mph) — significantly beyond standard IEC test parameters.

Dual-sided generation reduces LCOE

The TM7G72M-590 leverages N-type bifacial cell technology to capture reflected irradiance from the rear surface in addition to direct sunlight on the front. Depending on ground albedo and installation type — elevated ground-mount, carport, or flat commercial rooftop — rear-side gain can add 5% to 25% to effective output, directly lowering the levelized cost of energy (LCOE) compared to monofacial panels of equivalent rated wattage. The N-type substrate also eliminates the boron-oxygen defects responsible for light-induced degradation (LID) that reduce output in standard P-type panels over time.

Built for high-impact environments

Where standard panels use a single glass or backsheet construction, the TM7G72M-590 pairs a 3.2mm anti-reflective tempered front glass with a 2.0mm semi-tempered back glass — eliminating the moisture ingress risk of polymer backsheets and adding structural rigidity in high-wind and high-dust environments. The frameless dual-glass design is rated to 5,400 Pa front / 2,400 Pa back mechanical load. Hail certification to Φ55mm at 33.9 m/s makes it one of the most impact-resistant panels available through A1 SolarStore and a practical choice for hail-prone climates across the US Midwest, Great Plains, and Mountain West.

Application scenarios

• Residential rooftop (commercial-grade durability): Homeowners in hail-prone regions who need a panel that exceeds standard impact ratings without sacrificing efficiency.
• Ground-mount commercial & utility: Elevated fixed-tilt or single-axis tracker installations where rear-side albedo gain is reliably capturable.
• Carport & pergola structures: Bifacial dual-glass construction is ideal for see-through architectural installations where both faces are exposed.
• High-humidity & coastal environments: Dual-glass eliminates the backsheet moisture degradation risk common in salt-air or tropical climates.
• Desert & high-dust regions: High wear-resistance glass resists abrasion from windborne particulate.

System compatibility

The TM7G72M-590 operates at a maximum system voltage of 1500V DC and is compatible with all major string inverters and microinverters rated for 1500V systems, including units from Enphase, SolarEdge, SMA, Fronius, and Growatt. The 52.38V open-circuit voltage and 13.94A short-circuit current fit standard MPPT input ranges for residential and commercial string inverters. MC4 and MC4-EVO2A connectors with 12 AWG (UL) output cables are compatible with virtually all balance-of-system wiring. For bifacial performance optimization, a minimum 12-inch clearance above a high-albedo surface (white gravel, concrete, or light membrane) is recommended. Confirm mounting rail compatibility with the panel's dimensions (89.69 × 44.65 in.) and verify that racking load ratings meet the 5,400 Pa front-side wind/snow load spec.

Why choose the Talesun Solar TM7G72M-590?

Most 590W panels on the market use P-type cells with polymer backsheets — a combination that leaves them vulnerable to LID efficiency loss and moisture ingress over a 30-year lifespan. The TM7G72M-590 addresses both with N-type cell chemistry and dual-glass encapsulation, then adds verified Φ55mm hail resistance for buyers in storm-prone markets where panel replacement after a severe weather event is a real risk. The 30-year linear warranty at 87.4% retained output backs the long-term performance claim with an industry-leading guarantee.
