Trina's Vertex Modules Deliver Strong Results In TÜV Rheinland Testing

Jun 15, 2022 01:41 PM ET
  • The tests being conducted by TUV Rheinland at cologne presently have actually until now demonstrated clear effectiveness gains from the Vertex collection of monofacials as well as bifacials.
  • Last influence on LCOE will certainly naturally rely on the landed price of these modules for purchasers.

Leading testing company, TÜV Rheinland, just recently began conducting a 12-month area efficiency examination of Trina Solar's 210 Vertex ultra-high power monofacial and bifacial modules given that November 2021. Data examined for the initial 4 months shows that under numerous conditions of latitude as well as climate, the Vertex 600W+ modules have demonstrated strong bifacial gain, higher power return gain as well as even more secure working temperature level than normal referral modules. The outcomes will certainly be gratifying for Trina, which has actually been leading the push for the bifacials in 210 mm size.

The outdoor test sites include Cologne, Germany (pleasant zone), Thuwal, Saudi Arabia (tropical desert) as well as Hainan province, China (maritime). This field test concentrates on the project in Cologne, and also results show a 2% power return gain from the Vertex 600W bifacial modules.

Vertex 600W+ modules: 2% higher power yield in low irradiation

Cologne, with its four distinctive periods, as well as low irradiation was picked as a low irradiance zone.

The test example of Cologne's project site is Type A: 210 Vertex monofacial 650W module, as well as Type B: normal referral monofacial 535W module.

The meteorological information between 2021/11 -2022/ 2 can be seen below:

During the testing period, Trina Solar's Vertex modules got more than 2% higher power return. TÜV Rheinland has actually carried out thorough analysis on this outcome.

Evaluation: Low irradiation plus Vertex modules

Firstly, Trina Solar's 210 Vertex modules have actually shown exceptional power generation per watt under low irradiation problems. When irradiation is lower than 200W/m2, the power generation of 210 Vertex modules is 3.88% more than that of the recommendation modules; when irradiation is in between 200-400W/ m2, the power generation is 2.11% greater.

Second of all, it was winter in Cologne during the test period, and also irradiation and also temperatures were really low. The typical everyday solar irradiance was just 0.4 kWh/m2/day.

Taking 2021/12/22 as an example, solar irradiance for a whole day was 2.17 kWh/m2, a lot higher than the standard of 0.4 kWh/m2/day. However, 43% of the irradiation of the day was lower than 400W/m2, and also the highest irradiation of the day was less than 600W/m2. The low irradiation of a German wintertime highlights the premium power generation of Trina Solar's 210 Vertex modules.
