I think you all are out to lunch! You can’t compare electrochemical power devices based upon number of cells, or cell power, without knowing cell size. The reason for this is simple, the voltage per cell is the same regardless of size, what changes is the current, and there is a direct relationship between current and ASR, which results in the difference in efficiency and losses due to resistance.

In all electrochemical devices it is always more advantageous to have smaller cells, because you get the voltage for free, and you have higher efficiency and less resistive losses.

For example, I can have 1 cell with 1 volt and if I have 100 amps I then have a 100 watt cell. If I divide that 1 cell into 100 cells, then I have 100 volts so I only need 1 amp to produce 100 watts. V=IR so the more current the more losses due to resistive heating, that’s why power is transmitted at high voltage, your normal high power transmission line may only have a few amps, but you would never transmit the power low voltage and high current the losses would be so great that the transport efficiency would be close to zero and the heat generated due to resistance would destroy the power line.

Chris, Panasonic’s cells are a different size.

Hi Kelly.
But you state Panasonic’s latest HJT 96 cell puts out 330 W. “Awful” is backed up by basic arithmetic and 3.44 W per cell is “,awful” compared to 6.28 W per cell. I’m just the messenger of the message, numbers don’t lie.

Besides, in your reply you referred to the Panasonic’s latest HJT as a 60 cell. Even with less cells it’s at 5.5 W per cell. Much better than 3.44 W per cell but still lags behind Jinergy. Not that impressive being it’s their latest HJT panel.

Question: Is the Panasonic’s latest HJT 96 cell or 60 cell?

Thank you

Chris

Panasonic’s 96-cell modules are equivalent to traditional 60-cell modules. So Jinergy’s 72-cell module has 452-W output, while Panasonic’s 60-cell-equivalent module has 330-W output. “Awful” is really up to you.

You wrote Jinergy’s JNHM72 HJT cells of 2019 puts out 452.5 W with 72 cells at, I surmise 23.79% efficiency.

So: 452.5 W÷72 cells = 6.28 W per cell
At 23.79%

However, a few paragraphs further in the article you write that Panasonic’s latest HJT puts out 330 W from 96 cells at 20% efficiency.

So: 330 W÷96 cells = 3.44 W per cell
At 20% efficiency

How can Panasonic’s latest HJT have specs that are awful compared to Jinergy’s? This is outdated performance.

Please explain.

Thank you

Chris
