One of the more affordable solar panel options available the JA Solar JAP60S01 poly solar module doesn’t appear to be much more than another lacklustre 60-cell polycrystalline solar panel. Flying under the radar of most, there are a couple of surprises within the durability category which those weighing up there options should most definitely take notice of.

.Make and model:  JA Solar JAP60S01.

Variants: 260 / 265 / 270W/ 275W / 280W.

Durability, 12-year guarantee.

Outdated technology.

As outdated as polycrystalline solar panels are within the realms of pushing efficiency extremes they do however serve a purpose if well built. That is extreme affordability. With these two elements in mind, the JA Solar JAP60S01 poly may just have the edge over certain competition within a similar price bracket.

An uninspiring polycrystalline module design recently upgraded from 4 busbars to 5 busbar technology adds a little flair towards what is expected from a somewhat modern design. No enhancer such as PERC is included, although a white EVA substrate (back sheet) ensures a temperate environment for energy production. Without being module specific, only recognised awards was a JA Solar company award for “Top Brand PV Seal 2018” from EuPD Research. Without being directly associated with the JA Solar JAP60S01 poly solar module itself only partial point credits can be awarded.

JAP60S01 - Design
  • Polycrystalline cell.
  • 5 front bar contact.
  • No enhancers.
  • Glass-laminate (White).
  • out of date.
  • Other internationally recognised award system.
  • TÜV certified.


Here’s why one would select the JA Solar JAP60S01 poly solar module range over any other within a similar efficiency and pricing category. The durability specifications are elite in four key durability assessment criterium. Damp heat one of the most difficult test to pass subject the JA Solar JAP60S01 poly to 3000 hrs (higher than most). Ensuring expansion contraction durability, Thermal Cycle testing is equal with the world’s best at 600 cycles. Both salt mist and ammonia resistance ranks within the top tier of testing criteria.

Snow and wind loading obtain average durability scores meeting IEC Standard where alternatives exceed by much more. PID (Potential Induced Degradation) is resistant and hail impact is not listed which is always concerning and therefore drags the durability score lower.

  • Snow load 5400Pa.
  • Front wind load 2400Pa.
  • Rear wind load 2400Pa.
  • Damp heat testing 3000Hrs.
  • Thermal cycle testing 600Hrs.

  • Hail impact not listed.


Maximum module efficiency within 280W variants of the JA Solar JAP60S01 poly solar panel achieve up to 17.1%. Nothing special by any means, an end-user requires an abundance of mountable space in comparison to alternative technologies to ensure the JA Solar JAP60S01 poly is a viable option for maximum power production. Temperature Coefficient is average at -0.40%C. While a positive power tolerance exists but is limited to within 2% of the nominated power.

JAP60S01 - Efficiency
  • 17.1% Maximum module efficiency.
  • -0.40%°C Temperature coefficient.
  • 0/5% Power tolerance.


A common linear performance warranty the JA Solar JAP60S01 poly shall degrade no more than 2.5% within year-1, referred to as the stabilisation period. As of which after that the performance shall degrade at no more than 0.7% per annum over a 25-year period. Should the a module fail to live up to expectation JA Solar at most may provide a replacement (equivalent) solar panel. Costs of shipping and repair to be born by the end-user, although this may not suffice under varying regional legislation.

JAP60S01 - Performance
  • 2.5% degradation in the 1st year.
  • 0.7% degradation per annum.
  • 25-year linear performance warranty.
  • Parts only performance warranty.


A 12-year product warranty is certainly better than 10-years however the credit accrued for an above average warranty period quickly diminishes when there is no identified manufacture trained best practice installer network and a parts only product guarantee. More needs to be done in the way of ensuring paper warranties true substance and value.

JAP60S01 - Guarantee
  • 12-year warranty.
  • Parts only warranty.
  • No authorised installer network.


Competitively priced given the incorporated durability factors. Where the JA Solar JAP60S01 poly solar module fails to add value to the affordability score is within the design, efficiency, performance and overall guarantee.
