PRE RELEASE. Unlike many opinionated reviews, the Solar Review Panel Assessment Criteria compares the Aleo X83 Premium 325 – 333W  against the industries best known specifications.  The result, a solar panel review with no room for discretionary bias and the transparency you desire. 

.Make and model:  Aleo X83 Premium.

Variants:  325 | 330 | 333 W.

  Mechanical Loading, Cell Enhancer.

 Temperature coefficient. 


GREATER THAN 3.3 IS A VERY GOOD SCORE. The following content for the Aleo X83 Premium 325 – 333W. Series should be used as a guide only. Individual circumstances and compatibilities should always be taken into account when selecting the right solar panel for any given installation. This content has been built using the Solar Review Module Assessment Criteria 2.5 and above based on available product specifications at the time of writing. 


Design is what defines a particular solar panels energy production characteristics to assist greater value through innovation and advancement. 


X83 Premium Design; SUPERIOR
  • Monocrystalline.
  • 5-Wire front contact.
  • PERC Enhancer.
  • Glass-laminate (Black).
  • Inspiring.
  • Plus X Award 2020/2021.
  • TÜV Rheinland certified.
  • VDE certified.


On the front line of your new self sufficient power supply, durability of a solar panel assists greater reliability in return on investment in energy saving through the likelihood of more stable life expectancy in variable environments.


X83 Premium Durability; ELITE
  • Snow load 8000Pa.
  • Front wind load 5400Pa.
  • Rear wind load 5400Pa.
  • 3000Hrs damp heat testing.
  • 600Hrs thermal cycle testing.
  • PID free.
  • Salt mist resistance certification
    IEC 62701.
  • 40mm hail impact.


With limited available space, efficiency is key. More power from the nominated surface area is derived from the key criteria of solar panel efficiency.


X83 Premium Efficiency; GOOD
  • 19% Maximum module efficiency.
  • -0.40%°C Temperature coefficient.
  • 0/3% Power tolerance.


Performance is based on how well the the nominated solar panel technology should retain its specification and power class over time as guaranteed by the manufacturer. 


X83 Premium Performance: ELITE
  • 2% degradation in the 1st year.
  • 0.5% degradation per annum.
  • 25-year linear performance warranty.
  • Parts & service performance warranty.


As guarantee obligations can often be shielded by installer incompetence, should a solar panel manufacturer define an adequately trained installer network with a complimentary warranty extension (added end-user benefit), such guarantee has been considered as a base warranty more likely of adhering manufacturer installation specifications.

Important: A manufacturers obligations under guarantee will be obsolete if the solar panel is not installed to manufacturer specifications. Use an authorised installer.


Premium X83 Guarantee; ELITE
  • 25-year warranty.
  • Parts & service warranty.
  • Authorised installer network with no additional benefits.
