Trina is a solar panel manufacturer from China
The 640Wp TSM-DEG21C.20 model of series Vertex Bifacial (580-665)Wp has an efficiency of 20.6% with an area of 3.11m2. Higher panel efficiency and lower panel area is the preferred form factor for solar panels. The solar cell technology used in this model is Mono which commodity panel The No 1 ,2,3 reason for failure in solar panel is back sheet , solar glass coating and mechanical design. Select panels with best quality back sheet , high quality solar glass coating , and the best mechanical strangth against high speed winds
Solar panels , especially the highly marketed latest ones MAY NOT be compatible with solar inverter models due to technology gap between them This solar panel model has an output current of 17.19 Amps. Imagine the current as vehicle traffic that goes to the highway , which shouldnt be narrower than the income traffic.To avoid loss of power the outgoing solar panel output current must be less (or equal) to the maximum allowed input current of common inverter models typically at 13-15 Amps.
The wind mechanical strength of this model is 2400 (Pa) , same as industry standards.The wind speed of this model is 130 kmph. Select panels with industry best Wind Speed here
This 640 Wp model is warranted 542Wp at the end of 20 years.At the end of life , recycling of a solar panel due to lead , cross linked plastics in back sheet can be impossible. By some estimate this waste can stack up to the moon and back. Select one of the following models of solar panels to choose recyclable solar panels
