DAH Solar DHN-78X16/DG-635W

The DAH Solar DHN-78X16/DG-635W is a cutting-edge bifacial PV module designed for residential, commercial, and utility-scale solar projects. It features 156 high-efficiency N-type TOPCon monocrystalline cells (6×26), delivering an impressive 22.72 % module efficiency under standard test conditions. Compared to conventional PERC solar panels, TOPCon technology with rear-side passivation boosts conversion efficiency by approximately 3 %.

Equipped with double 2 mm low-iron tempered glass on both sides, this bifacial panel captures reflected irradiance to generate 5–25 % more energy depending on ground albedo. With a peak power rating of 635 W — achieved at a voltage of 47.4 V and current of 13.4 A — and a maximum system voltage of 1500 V, it integrates seamlessly into high-voltage arrays. Its low temperature coefficient of –0.29 %/°C ensures better performance in hot climates, maintaining reliable output even when ambient temperatures soar.

Engineered for durability, the module operates flawlessly across a wide temperature range (–40 °C to +85 °C) and benefits from an IP68 rating, making it suitable for harsh and humid environments. The robust silver-frame anodized aluminum frame provides mechanical strength and ease of mounting. Measuring 2465 × 1134 × 30 mm and weighing 34.2 kg, it balances high power density with manageable handling. Bulk packaging of 36 panels per pallet streamlines transport and installation logistics.

Backing its longevity, DAH Solar offers a 15-year warranty on materials and workmanship and a 30-year warranty guaranteeing at least 80 % of original power output. Exceptional low PID degradation (< 1 % in year one, < 0.4 % annually thereafter) and certifications to TÜV (IEC 61215, IEC 61730), CE, CAS, CQC, and INMETRO standards underscore this panel’s reliability and performance, ensuring a rapid return on investment over its operational life.
