Increased energy generation with half cell technology

This ALLMAX M Plus TSM-310DD05H.05(II) solar panel adopts half-cell technology. Two pieces of half cells are connected in series, the power loss caused by ribbon resistance is reduced to 1/4 of that in full cell, which results in decreasing of electrical resistance within the ribbon and finally improves the overall efficiency of module by more than 2%.

I just received my panels and expected them for possible damage as I was instructed by sales associate. Everything came undamaged. Thank you for fast delivery.
These panels are great! I could not justify spending so much more money just for the brand of a more expensive panel. Trina panels are very efficient and of high quality.
I had these panels for about 5 months now and had no problems with them. They did not require any maintenance so far and been working great. Very pleased.
I bought the modules about 4 months ago and now I can give an honest review. At first I was a little hesitant to go with Trina panels as I was not very familiar with them but I am so glad I did. These panels exceeded my expectations. They are so efficient even on days when I think I won't be getting any power at all! And they look so great. I am hoping they will continue performing like this for many more years.
