High-efficiency solar panel of 410 W, Monocrystalline Half-cell PV module, All black
To meet the market's demand for more efficient and attractive solar panels, we now offer this high-quality Monocrystalline Half-cell PV module 410 W. All-black means that the all-black half-cells are enclosed in an all-black aluminum frame, which makes the panels the most attractive on the market. But they are not only nice to look at, we sell them at perhaps the lowest price on the market?
Advantages of half-cell technology
From the beginning, the half-cell technology was created for use in space, they simply wanted to get more solar cells per square decimeter to get more power per surface solar panels. What they also did which was also good was to equip the new panels with three diodes per panel. These diodes led to an improved shadow response as the effect did not disappear completely when parts of the panel were in shadow but the remaining sunlit parts could continue to produce.
Smaller cells also meant reduced mechanical stresses, which in turn meant reduced risk of cracking. Half-cell modules have higher output power and are more reliable than traditional panels Because half-cell modules produce more power and are more efficient and reliable than their full-cell counterparts, their use can lead to money savings for the end user.
When the solar panels were introduced for civilian use in early 2018, they attracted enormous attention and quickly made an impression on the market. The success was a fact and already after the first year the market share was up to 5%! This share is expected to rise to 40% in 2028 so there is no doubt that this is currently the hottest technology on the market
This is how it works
Half-cell modules have solar cells that are halved, which improves the module's performance and durability. Traditional panels with 60 and 72 cells have 120 and 144 "half-cut" cells, respectively. When solar cells are halved, their current is also halved, so resistive losses are lowered and the cells can produce a little more power. Because the cells are smaller, the distance between cells does not have to be that wide and they can be placed closer to each other.
