LG plays the CELLO to create optimised Solar Panels
LG Solar has never shied away from investing time and money in order to optimise the performance of their solar panels. The new line of panels, LG NeON 2 and LG NeON 2 Black, as well as the LG MonoX 2 models are equipped with new improvements that LG has summarised under the collective term CELLO. To find out what this means in detail, we spoke to Dr.-Ing. Matthias Nell, product manager for the EU Solar Business Group.
The term CELLO stands for “Cell connection with Electrically Low loss, Low stress and Optical absorption enhancement”. What exactly does this mean? For the answer to this question Nell, who incidentally wrote his PhD on the topic of solar cell technology, provided us with some insightful information. We could not imagine a better candidate to clarify this method of optimisation.
“The main focus of CELLO-Technology is a brand new method of wiring the solar cells in a panel,” explains Nell. It’s important to note that each solar panel is made up of a total 60 individual, interconnected solar cells. These cells produce power separately, which then collects together and flows off to be used. Usually these individual cells are each connected with 3 thick wires (busbars, a metallic bar used to conduct electricity). The problem with busbars is the design of the wires themselves. It is necessary for these wires to have a certain diameter; this size causes an electrical resistance against the power that the cells deliver. Even though the resistance is quite small, it decreases the overall performance of the solar panel.
LG Electronics has replaced the 3 thick, flat rectangles with 12 thin wires, which are also made of a conductive material. “It would be most favourable to create these wires from a highly conductive silver. This would, however, not be pragmatic in relation to its cost-benefit ratio. Nevertheless, a percentage of the new wiring is silver,” states Nell. The combination of a decreased wire diameter and conductive material of the 12 wires lowers the electrical resistance in the solar panel considerably. The result is a solar panel that delivers an enhanced performance.
The new wiring brings another factor into play, namely the outer design of the wires. The previous connecting wires were always flat and angular, the new ones are round. “More of the sunlight the wire is exposed to can be reflected onto the panel through the round form,” explains Nell. “Our exact goal is to capture 100% of the sunlight that shines on the panels and, if possible, to use it all.” The angular wires had performed in such a way that a small portion of the available reflected sunlight was wasted. This improvement seems to yield a relatively small effect, but if one imagines a roof fitted with 10 to 20 solar panels, the sum of the extra sunlight used is a significant increase in performance.
An Active Back Panel
This goal also extends to the circuitry of the solar cells’ backing. The front and back structures of LG solar cells are almost identical. In this way, sunrays that are reflected onto the backside of the solar cells (e.g. off the roof tiles) can also be used to generate electricity. “In future we will use a transparent film as a panel backing. Then the panels would be active on both sides and deliver more power,” says Nell. “The completely bifacial solar cell is a concept with a bright future.”
Protection against Reverse Voltage
Along with the intelligent wiring of solar cells on each panel, LG has also implemented a safety mechanism for reverse voltage. This operating mode occurs, for example, when connected cells are partly in the shade – possibly behind leaves on a tree and partly exposed to sunlight. In this case a negative voltage could occur on the solar cells in the shade and cause long-lasting damage. LG has combined the 60 solar cells of a solar panel in 3 sub-strings and equipped them with protective diodes. If the voltage exceeds a certain amount, the solar cells in the shade would virtually switch off. This eliminates the possibility of any damage occurring.
“With all these measures in place, we’ve actually achieved 2 goals,” summarises Nell. “Firstly, we were able to increase the performance of our solar panels, they now have a remarkable 330 watt peak. Secondly, we’ve enhanced the durability of each solar panel by successfully reducing the yearly degradation, or physical loss of power, from 0.7 % to 0.6 % per year.” This in turn has had an impact, allowing LG Electronics to extend the product guarantee of its solar panels to 12 years and additionally ensuring that each panel will still perform at a minimum of 84.8 % of its original output capacity for 25 years.
That’s how the LG CELLO melody goes – better performance, enhanced durability, guaranteed safety. Sounds pretty good, doesn’t it?
