Hyundai offers compact 250W
high-performance modules for UK
Hyundai has launched a new 250W
module type series in the UK,
specifically to meet UK
installer requirements. The S250RF(BF) is a 54-cell
250W modules using monocrystalline Passivated Emitter, Rear Locally-Diffused Cell (PERL) cells
enabling a claimed 10% reduction in roof space to achieve a 4kW system.
Since the arrival of the
Feed-in-tariff in 2010, the UK
market has seen the 250W module move from being the holy-grail to the work
horse of domestic PV. 250W modules are the most preferred module size for
domestic installations because 16 modules of 250W can make an exact 4kW system
and comply with the best FiT rates for residential
rooftop systems. However, constant cell efficiency gains have led to higher
module performance levels within the standard 60-cell configuration, resulting
in less system optimization and more complex design calculations. With
conventional 60-cell modules, a 4kW system may require about 23 m2
of space and weigh 265kg.
module for example uses a monocrystalline Passivated Emitter, Rear Locally-Diffused Cell (PERL)
54-cell black-framed module, retaining the UK installers preference for 250W
modules for calculating system size and pricing. The modules are therefore
smaller (998mm x 1,480mm) and lighter (15.4 kg)
and require 20.7 m2 of
roof space (10% smaller than 60-cell module) and weighs 215.6 kg (19% lighter) to
achieve a 4kW system. This allows small or weaker roofs to have optimized
rooftop installations, despite this previously being unavailable limiting
and small commercial rooftops.
uses monocrystalline PERL cells in a (6x9 matrix)
series with cell efficiencies of 20.4% (max). They have anti-reflective coating
low-iron tempered glass, 2.8 mm (0.11”).
Encapsulant is EVA. IP68, weatherproof, IEC certified
(UL listed) Jbox and 3 bypass diodes to prevent power
decrease by partial shading.
Hyundia’s full range of 250W modules is available
in the UK
exclusively through BayWa r.e. Solar Systems and Segen.
