QCell Q.Peak DUO-G5 Advantage

Everyone knows solar panels are a good idea but are there certain ones that are a better idea than others? The answer is a resounding yes. Let’s take a look at the new QCell Q.Peak DUO-G5 as an example of a superior and award winning PV module.

There are many innovations that have gone into improving the power output of the Q.PEAK DUO-G5 solar panels.  One is that the solar cells are interconnected with wires instead of flat ribbons on cells. These wires take up less surface area allowing the sunlight to hit more of the cell area. The innovative design also allows light reflected off the wires to be redirected back onto the module surface. This alone increases power production by 2.5%.

Another design advantage was QCell’s choice to use six busbars on each cell. This decreases the space between busbars which means that the individual electrons have a shorter path to the busbar, decreasing losses to resistance. The extra busbars also allow better electron flow as there are more busbars to carry them. The six busbars result in a 1% increase in power production.

Half-size solar cells in the Q.PEAK DUO G5 module increase power production by 3% by reducing the current which reduces the resistive losses within the cells. The half cell design also increases stability against pressure on the module, reducing the risk of the cell cracking.

The chance of cracking is further reduced by the way the cells are cut with a smoother edge than typical solar cells. Plus, with the if a cell does crack, the six busbars mentioned above help mitigate the effects of the cracks causing resistive losses. Creating a much more stable design over all.

This more stable design means a lower degradation rate of only .054% annually. QCell offers the guarantee of at least 85% production after 25 years on these innovative solar panels.

The DUO-G5 PV modules are also different in their cell interconnection design. The upper and lower sections of the modules are connected in parallel instead of series. This results in higher power production when the module is partially shaded because the unshaded half of the module can still perform at 100%.

Other technology that increases the performance of these solar panels is the Anti PID technology that reduces losses in wet climates. Hot-spot Protect (HSP) eliminates cells that have a high risk of creating hot spots from the production line keeping the modules hot spot free. As a matter of fact, all the solar cells on the production line are tracked with laser markings that are part of QCell’s TRA.Q traceable quality system. Anti LID and Anti LeTID technologies further reduce output losses from exposure to heat and light.

Overall, the innovations in these QCell Q.Peak DUO-G5 PV modules make it one of the most efficient and reliable solar panels on the market.
