ETFE Cell Lamination
To offer the best possible life and performance from this solar range, Roman
is using ETFE material to achieve the ultimate cell protection. The ETFE
material has many features which make it ideal to be used as a protective
surface over a solar cell. Technically known as Ethylene Tetrafluoroethylene,
ETFE has a polymer base and has been design to have high strength over a
wide temperature range and be highly resistant to corrosion. ETFE is water
proof and highly transparent at 97%, has excellent chemical resistance and a
relatively high melting temperature. It is also extremely UV resistant, will not
discolour or degrade over many years of use.
Protecting the C60 cell with ETFE will effectively double the lifespan
compared to that of polyethylene terephthalate (PET) cell lamination.
Applied as a thin film over the cells and uniquely textured from the laminating
process allowing more light to be captured by the undulating surface adding
further efficiency to the C60 cell. Due to the non-adhesive properties, ETFE
has a ‘self-cleaning’ effect and will naturally reduce any build-up of foreign
deposits which may block the suns light. These deposits do not sick and can
easily be wiped off or washed away.
Auto Restart Technology
All Roman Solar Charger Kits and the 45W Mat Kit are equipped with the
latest in solar charger technology offering ‘Auto Restart’. The controller knows
the difference between the various charging states and will distinguish if a
battery is fully charged or it needs to reconnect if charging is interrupted due
to lowlight or shadowing conditions.
