Make sure your profitability is not affected!
Although they may not be seen at first glance, when the materials are low quality and/or manufacturing processes are not suitable, they can lead to problems of production and profitability in the short or medium term. We all want to make the best purchase and get the maximum profitability for our projects. For this reason, when a price is very low or appears to be a bargain… Watch out! Regarding solar modules, it can be difficult to detect low quality products since, apparently, all of them look the same. However, it is important not to make the purchase decision guided only by the lowest price.
We have got used to constantly seeing progress in photovoltaic solar technology, and improvements in its production process that result in a more competitive price. But, in the same way, there is a price war where the only strategy of some companies is to lower the ratio $/Wp at any cost, regardless of the final quality, real power and service life of the product.
1. Mismatch | In the solar module’s cells and the strings in series
Discrepancies between cells of a same module and later installation in series of the strings of a solar plant, cause the total output power to be limited by cells with the lowest current values. For this reason, a correct classification, traceability and its correct testing at the factory are essential.
2. Hot Spot Effect | Accelerated degradation of solar module
They can be caused by partial shading, due to minor production flaws and wrong connection of cells and/or bypass diodes,
turning them into heat sinks.
3. Microcracks and other defects | Due to poor quality control processes
Typical examples: Partial/total microcracks, dirt, remains of pewter, etc.
Forget the hidden defect
Using grade A+ cells
With our rigorous selection process to assemble the TM-Series modules, we obtain a superior A+ cells classification. In this way, mismatch, hot spot and microcracks defects are avoided.
Quality controls and PID Free
A correct traceability and classification during the packaging process will facilitate the subsequent selection of modules in the installation of the photovoltaic plant. In addition to the selection process already mentioned, we also subject TM-Series modules to exhaustive quality controls to minimize any small defect. Therefore, we include the Certificate PID Free, which guarantees perfect operation in the most extreme conditions.
In Tamesol, with the improved production guarantee, of up to 30 years and linear, we provide our customers peace of mind and confidence in the energy production of all our modules.
“Thanks to the research and development efforts carried out in recent years, we have completely redesigned our TM-Series pv modules. Now much more for less. A solar module that allows us to offer 30 years of production guarantee.”
