490 Wp Bifacial Back-Contact Solar Panel – Heckert ZEUS 3.0+ 108 490 73 (A) performance

Maximum Output per Square Metre – Heckert ZEUS 3.0+ with 490 Wp

Roof space is limited – your power needs are not. With 490 Wp and a module efficiency of up to 24.5 %, the ZEUS 3.0+ performance gets the most out of every square metre: N-type ABC back-contact technology moves all electrical contacts to the rear of the cell, so the entire front is available as active area.

Back-Contact: More Yield, Fewer Losses

Without metallic front contacts, there are no shading losses on the cell. The result: higher power density, optimised behaviour in shade with a low risk of hotspots and an improved temperature coefficient of -0.26 %/K – the panel stays powerful even on hot summer days.

Performance Design for Maximum Output per Area

The performance variant (white) is designed for maximum efficiency and is the right choice when maximum energy yield is the priority – ideal for flexible architectural requirements.

Bifacial Double Glass for Extra Yield

The glass-glass construction (2 × 2 mm, thermally toughened) makes the panel extremely durable and mechanically robust (test load +5400/-2400 Pa), with a bifaciality of up to 43.6 %. Via the transparent rear, the bifacial panel generates additional yield from reflected light.

30-Year Product and Performance Guarantee

As a German guarantor with direct service, Heckert Solar provides a full 30-year product and 30-year performance guarantee – investment security over the entire lifetime of your system.

FAQ: ZEUS 3.0+ 490 Wp

What does back-contact technology mean?

All electrical contacts are on the rear of the cell. This maximises the active cell area, reduces electrical losses and ensures a uniform look with no visible busbars.

What systems is the panel suitable for?

For high-quality residential and commercial systems that need to generate as much solar power as possible from limited space – from private homes to demanding commercial roofs.

Is the panel suitable for 1500 V systems?

Yes, the maximum system voltage is 1500 VDC.
