Some sizes are now only available in the PremiumPlus range (the dimensions will be the same but the output is higher)

he Sunpower company limits the size of flexible solar panels manufactured using their cells to 150W.  The failure rates for larger panels increases due to mechanical and thermal stresses on the panel.  All panels have a 1 year warranty.

The advantages of ETFE technology

ETFE (Ethylene-Tetra-Fluoro-Ethylene) is a high-strength fluorine polymer that is corrosion and stain resistant, non-stick self cleaning, and retains its clarity (and therefore light transmittance) ensuring long service life for solar panels.

It will not discolour or degrade from exposure to environmental pollution, UV light, harsh chemicals or extreme temperature variations. The textured surface offers an extra layer of protection and robustness and provides a small increase in efficiency due to its anti-reflective properties, which means more light passes to the cells.

The importance of using genuine A grade SunPower cells

Solar panels containing SunPower E20® series cells developed in the US are the highest efficiency panel available on the market today, providing more power in the same amount of space. Efficiency refers to the percentage of sunlight hitting the panel that gets converted into electricity therefore a higher panel efficiency means that the panel can generate more power.  These cells capture significantly more sunlight and conduct more electrical current than other solar cells.  Our manufacturer is one of only a few manufacturers in China that has certification from SunPower and access to genuine SunPower cells and provides the SunPower certificate of origin.

 

Monitoring quality

Premium flexible solar panels with ETFE technology for quality

These Monocrystalline PhotoVoltaic (PV) flexible solar panels carry the Solar 4 RVs brand RADpower logo so we are very focused on consistent quality and reliability. 

Our manufacturer has a clear understanding of our Australian quality expectations and customer needs.  They manufacture to our specifications for each order we place.  This ongoing professional relationship and communication facilitates reliable and consistent stock quality.  We have visited the quality in China as part of our continuous improvement and quality control program.

We do not purchase other ‘grades’ of cheaper off-the-shelf panels that may have overlapping, damaged or inferior cells, sharp edges, unsealed junction boxes or silicone partially blocking cells near the junction box. 

Our support and warranty service is unmatched.
