Advantages of ULICA 455w mono perc Tierc 1 Solar Panel
The Ulica 450w solar panel with its new split cell technology improves the performance of the photovoltaic system in many aspects, here we can see the main ones:
Decrease in thermal resistance:
Thanks to the use of the split cell, the current that circulates through the panel is divided into two parts and the thermal resistance losses decrease. Simply with this configuration change in the panel we have a gain of up to 10w compared to a conventional module.
Panel temperature drop:
Split cells have better heat dissipation than a conventional cell so there is also less chance of having a hot spot in the future. In addition, Perc technology, thanks to the use of reflection, further reduces temperature losses.
Better behavior in shadows: Due to the fact that the panel is divided into two chains connected to each other in parallel, if we have the effect of a partial shadow, half of the panel continues to work, which is why we reduce losses very considerably.
The multi bus bar of its cells has the advantage of reducing the electrical resistance by limiting the distance between the transfer of electrical current of the conductors. The gain is between 5 and 10w per solar panel and the chances of having defects such as "microcracks" decrease significantly.
Charge regulators for ulica 455W panels
Ulica 450 w mono perc split cell panels have very similar electrical characteristics to 72 cell panels. In fact, although the panel is made up of 144 divided cells, in reality, being in two strings in parallel, we have 144/2 = 72 cells
The charge regulators that we can use with these panels are therefore the same as with the 72-cell panels. We recommend using mppt for its higher performance and in order to take full advantage of the high performance Csun board features.
Pwm regulators can be used with these panels in 24 and 48 volt systems, although we must consider that the technology of these panels slightly increases the voltage compared to a standard 72-cell panel. It is necessary to check the maximum voltages admissible by the pwm and mppt regulators for a correct connection without exceeding the limits.
