Recently Trina Solar was awarded the LCA (Life Cycle Assessment) certificate for its 210mm Vertex modules by TÜV Rheinland, becoming the first solar company to receive LCA certification for 210mm modules. With the advantage of 210mm wafers, the Vertex modules achieve low carbon emissions.

LCA follows the methods and requirements of ISO 14040/ISO 14044 to conduct scientific and stringent tests of life-cycle carbon emissions and other indicators of the assessed subject.
Trina Solar conducted a comprehensive LCA analysis of Vertex modules on more than 10 indicators, including energy consumption, raw material use, acid rain, eutrophication, toxins and waste, among others.
The products, sampling from Trina Solar’s major production factories around the world for testing and certification, cover the full range of p-type 210mm modules with mono-crystalline from Vertex S 410W to Vertex 670W, and show a lower emissions footprint than is typical among China module producers.
The average carbon emissions of PV modules’ lifecycle assessment “from cradle to gate” in China are about 550kg CO2_E/kW. Trina Solar’s 210mm Vertex modules carbon emissions are as low as less than 400kg CO2_E/kW, without using special silicon materials. Its carbon emissions are at least 30% lower than the industry average in China.
Taking the 30-year product life cycle as an example, Trina Solar Vertex modules have an electricity emission factor of less than 0.01. Carbon emissions of thermal power are higher than 100 times.
Low-carbon certification will be an important consideration for customers when they select the products to use.
Have you checked out our YouTube page?
We have a ton video interviews and additional content on our YouTube page. Recently we debuted Power Forward! -- a collaboration with BayWa r.e. to discuss higher level industry topics as well as best practices / trends for running a solar business today.
Our longer running side project is The Pitch -- in which we have awkward discussions with solar manufacturers and suppliers about their new technology and ideas so that you don't have to. We've discusses everything from residential rail-less deck attaching and home solar financing to large-scale energy storage value stacking and utility-driven new home solar + storage microgrids.
We also post our Project of the Year announcements there! Interviews with this year's winners will be up starting the week of Nov. 8. Head there and subscribe today to stay on top of all this extra stuff.
