Aiko Stellar 2N+78 770W N-Type ABC Bifacial Solar Panel

The latest Aiko Stellar 2N+78 770W N-Type ABC Bifacial Solar Panel price in Pakistan is Rs. 33,000/- updated on October 19, 2026.

The Aiko Stellar 770W is a bifacial dual-glass solar panel from AIKO’s Stellar series. Its full model name is Stellar 2N+78 770W (AIKO-A770-GRH78Dw), and it uses N-type ABC (All Back Contact) cells.

Overview

The Stellar 2N+78 range covers 765W to 800W, with module efficiency of up to 24.9%. This 770W model has a rated efficiency of 24.0%. AIKO designs the Stellar series for higher power output and lower LCOE. As a result, it suits large rooftops as well as ground-mounted systems where maximum generation per panel matters.

It is a 2nd-generation, large-format 156-cell module. It measures 2465 × 1303 mm and weighs 39.8 kg, so plan your mounting structures for its size.

N-Type ABC (All Back Contact) Cell Technology

ABC cells place all electrical contacts on the back of the cell. Because the front surface has no metal gridlines, more of it can absorb sunlight. The result is higher power from the same footprint. AIKO calls this Higher Power and Lower BOS. In other words, you need fewer panels, mounting structures and cables for the same system size. In addition, the panel has a cleaner, more uniform appearance.

Partial Shading Optimisation and High Temperature Restriction

AIKO lists partial shading optimisation and high temperature restriction among the core technical features of this module. Dust, leaves or nearby objects can shade part of the panel. When that happens, the module limits the power loss and restricts the temperature rise in the shaded cells. As a result, it improves both energy yield and safety.

Better Temperature Coefficient

The power temperature coefficient is -0.26%/°C. So the panel loses less output as cell temperature rises, which is a real advantage in Pakistan’s hot summers. The bifacial factor is 80 ± 5%. Under BNPI bifacial test conditions, the rating of the Aiko Stellar 770W is 845W. This reflects the extra energy that the rear glass collects.

Durable Dual-Glass Construction

The module uses 2.0 + 2.0 mm coated semi-tempered dual glass in an anodized aluminium frame. It also has an IP68 junction box and 3 bypass diodes. Its maximum static load rating is 5400 Pa on the front and 2400 Pa on the back. Furthermore, it carries an IEC Class A fire rating. AIKO also lists micro-crack resistance as a core feature of the ABC cell design.

15-Year Product and 30-Year Performance Warranty

AIKO backs the panel with a 15-year product warranty and a 30-year linear performance warranty. Degradation stays at ≤1% in the first year. After that, it stays at ≤0.35% per year from year 2 to year 30. Therefore, the warranty guarantees 90.6% of rated power at year 25 and 88.85% at year 30.
