Upgrade of high performance solar modules from REC and Trina (Solar)

The REC Group began the production of household solar modules of the N-Peak Black series, with power up to 325 W. At the same time, Trina Solar has released four new modules in its Tallmax, Duomax, Duomax Twin and Honey series - some of which reach 415 watts.

The standard argument of skeptics of lowering the price of solar energy at present is that pretty soon the modules will no longer become cheaper, because resources (aluminum, copper, plastic and silicon) will slow down this process.

While this argument does make some sense in absolute dollar terms, skeptics lose sight of the core detail. We do not evaluate our industry in commodity prices; we estimate it in units of electricity generation per solar module. And the price per watt, based on increased efficiency, varies to some degree regardless of the price of the product. Thus, prices for “solar” electricity may continue to fall, as output increases, and resources are used more efficiently. Which means that the battle is not over.

And to emphasize this, the REC Group and Trina Solar have released new solar modules.

REC : N-Peak Black

The REC Group's N-Peak Black Series solar modules now reach 325 watts. Solar modules based on n-type photocells are oriented to consumers who appreciate the aesthetic side *: black frame, black substrate and, of course, black single-crystal solar cells.



All modules of the N-Peak series use half-light photocells and a double contact box [in fact, even triple: three blocking diodes, which contribute to efficient operation with partial shading, but two current cables - approx. translator] .



Solar modules are manufactured at a full-cycle plant in Singapore (for more information about production, click here ). The first deliveries are scheduled in April.

Trina Solar : TALLMAX, DUOMAX and Honey black

When introducing new products, Trina Solar focused on 72-cell solar modules, updating four of its series:

- TALLMAX - highly efficient series of modules;
- DUOMAX - solar modules using glass as the back substrate
- DUOMAX Twin - solar modules of the DUOMAX series, but using two-sided solar cells
- Honey black M - “esthetic” series with black photocell, black noon and black frame *



The company offers a wide range of solar modules for various applications.

In Trina Solar they say that solar modules with an output power of 415 W (which is more than the previous record of the company at 370 W) are already leaving the conveyor lines, but they don’t say how such an increase in productivity was achieved. Probably due to bilateral modules, since there are no “clean” 415-watt modules on the company's website [for example, it is stated that the DUOMAX twin DEG14C.07 (II) modules can produce up to 456W, but this is probably already at absolutely perfect reflection conditions - approx. translator] .

At the same time, in a press release, the company stated excellent performance indicators of these modules:

Increasing the power output of modules from 370W to 415W will help reduce costs in the system cost balance ( BOS ) by 4.5% to 8.5% and reduce the normalized cost of electricity ( LCoE ) by 2.5% to 4.6%.

The company uses a multi-busbar design (MBB) design, double glass and half double-sided solar cells [strangely, very similar to the description of the N-Peak series from the REC Group, on the Trina Solar website did not find descriptions of such modules - note . translator]
