RADpower flexible solar panels by Solar 4 RVs, Solar 4 Boats

 

RADpower with the latest SunPower A grade Maxeon Gen III cells

These premium RADpower thin, lightweight solar panels use SunPower's latest release highest efficiency A grade Maxeon Gen III cell so less cells are required in a flexible solar panel to obtain the same output of power.   Now with an even more pronounced, tougher, textured, robust surface compared to our previous R

RADpower PremiumPlus flexible solar panel with the highest efficiency SunPower cells available

ADpower SunPower range.

 

Features

  • Highest efficiency - made with genuine A grade SunPower cells (no seconds);
  • Premium quality - ETFE top layer for UV resistance and textured surface for extra robustness;
  • Lightweight - no glass or frame;
  • Thin - only 3mm thickness;
  • Sealed junction boxes to prevent moisture penetration that can cause corrosion;
  • Easily installed -  via adhesive sealant, high bond double-sided tape (no mounting brackets required).
  • Eyelets or zips can be easily added

 

RADpower panels have guaranteed genuine SunPower Maxeon cells

Our manufacturer is one of only a few manufacturers in China that has certification from SunPower to access genuine SunPower cells and they provide us with the SunPower certificate of origin.

Comparison of Sunpower Maxeon Gen II and Gen III solar cells

Note that the efficiency of the Gen III cells has increased by 1.3% over the Gen II cells, the voltage has increased by 6.8% and the amps has reduced by 2.5%.  Very significant is the higher output at higher temperatures.  The loss at high temperatures has been reduced by over 20%, so for a panel with Gen III cells operating at a very higher temperature the increase in output is at least 4% compared with a Gen II cell.

 

Sunpower Gen III cells have a higher efficency with higher voltage at a slightly lower amperage. The panel dimensions are reduced because less cells are required to obtain the same output power.  The output at higher temperatures has also been improved.

The 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.

 

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 genuine GEN III SunPower 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.
