PRE RELEASE. Unlike many opinionated reviews, the Solar Review Panel Assessment Criteria compares the Suntech PERC Mono Panel 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:  Suntech PERC Mono Module.

Variants: 295 / 300 / 305 / 310 / 315 W.

  Guarantee, Performance.


GREATER THAN 3.3 IS A VERY GOOD SCORE. The following content for the Suntech PERC Mono Module 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 2.0 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.

PERC Mono - Efficiency
  • 18.9% 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.

PERC Mono - Performance
  • 2.5% degradation in the 1st year.
  • 0.7% degradation per annum.
  • 25-year linear performance warranty.
  • Parts and 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.

PERC Mono - Guarantee
  • 12-year warranty.
  • Parts & service warranty.
  • Authorised installer network, with no additional benefits.


All well and good having the greatest technology, but what if that technology is simply out of reach for most? Adversely, the cheapest product may lack essential capabilities expected by many end-users. Put price into perspective. Affordability is where price and technology come together to help determine value.
