Photovoltaic technology is the most efficient of all alternative energies. However, when it comes to photovoltaic panels, there are always opportunities for improvement, but we present to you the material responsible for solar panel failure, even if China wants to reuse it.
The material that caused solar panels to fail has been brought back to life
The Chinese company Aiko, specialized in the research, design, development and construction of solar panels, will launch a new type of photovoltaic panel made not of heterojunction, perovskite or diamond powder, but of a material that has failed as a part in the past.
We are talking about N-type photovoltaic panels, like the old ones, but with a new combination that achieves a performance of more than 25%. The secret is that the company moved the copper bus rails to the back of the solar panels, reducing the shading on the cells.
The features of this new solar panel: it surpasses everything known and is very cheap
The new solar panel was named Comer 3N72e and is the workhorse of Aiko’s new New Infinite series. It comes with a maximum power of 650W and the N-type solar cells have a conversion ability of sunlight into electricity, which the highest on the market at 25.2% and the costs are very low.
On the other hand, the conversion efficiency is determined by the large number of photovoltaic cells, namely 144, which are made differently from the old ones, which gives them great durability. It is larger than conventional ones and is 2,278 mm high, 1,134 mm wide and 30 mm thick.
This is due to the movement of the copper bars in the panel configuration. But despite being large, they are also very light as their weight is less than 30 kg. This is because it has a mono-glass design with only one layer of tempered glass with a thickness of 3.2 mm, very transparent.
It has a reduced but very resistant aluminum frame, made in one piece and the perforations are already made for installation. Speaking of which, they can be placed either horizontally or vertically so that their N-type cells receive the greatest amount of sunlight.
In terms of durability, it also has many advantages. The annual degradation of the materials, especially regarding the solar cells, is less than 1% in the first year and from the second year onwards it is estimated to degrade by up to 0.35%.
That is why it offers a 30-year efficiency guarantee, after which the capacity will be at least 88.85%. Aiko has complete confidence in its solar panels, so much so that it offers a 15-year warranty on material and workmanship. The operating temperature ranges from -40 to 85 ºC and is IP68 certified..
The Chinese manufacturer is not yet afraid of perovskite modules
With these new N-type solar panels, Aiko is confronted with Japanese perovskite technology which he is not afraid of. Because it still has serious stability problems despite its high performance and low production costs, it will therefore take between 5 and 10 years before it is commercially available.
In short, the old and well-known N-type solar panels come out in force with this new model that revives this material that once marked its failure. Likewise, it represents strong competition for perovskite plates, which have not yet appeared on the market.
