JA Solar 545W MBB Half-cell Module
In May 2020, JA Solar introduced its new product, JA Solar 545W, which is planned for mass production in the third quarter of 2020, with a scheduled production capacity of 14GW. With its constant improvement of product technology, the manufacturer recently successfully pushed the energy output of its latest product to 545W.
JA Solar 545W module used JA Solar’s PERCIUM PLUS cell technology, and the Ga-doped M10 (182 mm * 182 mm) silicon wafers, that has been officially accepted as large-scale wafer size standard by the top seven China-based PV manufacturers. The module also used an 11-busbar and half-cell design. All of these enable the energy output of the mass-produced 72-cell type JA Solar module to reach 545W.
The enhanced module will lower manufacturing costs throughout the entire solar industry supply chain, especially, the M10-based high power module will bring end users great value and keep our clients with improved competitive benefits. At Pas Solar, you are offered the JA Solar 545W for sale.
Half-cut solar photovoltaic cells were created by REC Solar in 2014 and were created to increase the power output of solar panels. We will explain more about how they work below, but you can think of a half-cut cell as two individual panels in one.
In this article, we will explain how half-cut solar PV modules function, why their design enhances the performance of standard solar panels, which factories use them, and the possible future of half-cut solar cell technology. We hope this article can give a better understanding to those who want to buy JA Solar 545W.
How does JA Solar 545W work?
Half-cut solar cell technology improves the power output of JA Solar 545W panels by decreasing the size of the cells, so more can be placed on the panel. The panel is then divided in half so the top works independently of the bottom, which means more power is generated – even if one-half is shaded. That’s the general overview – below, we go into more details.
Traditional monocrystalline solar panels usually have 60 to 72 solar cells, so when those cells are separated in half, the number of cells grows. JA Solar 545W has 120 to 144 cells and is typically made with PERC technology, which delivers higher module efficiency.
The cells are divided in half, very finely, with a laser. By cutting these cells in half, the electrical current within the cells is also split in half, which means that resistive losses from traveling energy via current are decreased, which, in turn, means better performance.
Since the solar cells are cut in half and are as a result reduced in size, they have more cells on the panel than conventional panels do. The panel itself is then cut in half so that the top and bottom parts work as two different panels – generating power even if one half is shaded.
The key to JA 545W design is another way of “series wiring” for the panel, or the way the solar cells are linked together and pass electricity via a bypass diode within a panel.
In a standard panel, when one cell is shaded or faulty and does not convert energy, the whole row that is within the series wiring will stop generating power. If you are looking for an efficient, powerful panel to buy, we can show you the JA Solar 545W price in Dubai. If you are lucky, you would find a JA Solar 545W sale and buy the panel at a much lower price.
With the standard full-cell string series wiring, if a solar cell does not have much sunlight, every cell within that series will not generate power. This makes a third of the panel useless.
If a solar cell in row 1 is shaded, the cells in that row (and that row only) will stop generating power. Row 4 will keep on producing power, producing more power than a standard series wiring because only one-sixth of the panel has ceased to produce power, instead of one-third.
You can also see that the panel itself is divided in half, so there are 6 total cell groups instead of 3. The bypass diode links in the middle of the panel, rather than on one side like the standard wiring.
What are the advantages of JA Solar 545W modules?
The benefits of JA Solar 545W panels are countless.
They enhance the power output and performance of solar modules because they deliver a higher shade tolerance because of their exceptional wiring system.
This means that if your house has some trees that cast shade onto your roof at certain hours during the day, your whole solar panel will not become useless like it would with a standard solar panel. Half-cut cell modules cost more than standard modules, but Pas Solar can deliver you JA Solar 545W for sale. So, to learn the price of a Solar 545W price, contact our sales team at Pas Solar, and see if they have a JA Solar 545W sale.
Another advantage is the fact that they typically offer a higher wattage than traditional panels, even up to 380 watts for the REC Alpha compared to conventional panels which are normally within the 250-watt range, meaning they generate more power per square foot.
Also, the effects of hot spots are less intense on your solar panels with JA Solar 545W. Hot spots are the shifting of surplus heat on a panel from a very hot part to a shaded, colder area. With a half-cut cell, hot spots will not be as bad because there are more cells to distribute the excess heat.
JA Solar 545W also lower power loss suffered by conventional panels by lowering internal resistance. Internal series resistance happens just by the nature of power traveling through the panel through electric current.
But because solar cells are sliced in half, there is less current produced from each cell, meaning less resistive loss. If you buy JA Solar 545W, you will benefit from all the benefits mentioned above.
Although JA Solar 545W offers many benefits, they are more expensive because they are more difficult to build, with an improved soldering process and laser cutting. Ultimately, it is up to you to choose if the overall advantages make the increased cost worth paying for. These advantages are the reason why many dealers and installers always sell Solar 545W Panels.
What manufacturers use half-cut cell modules?
Ever since REC Solar invented half-cut cell technology, many solar manufacturers have followed suit. Some of the more popular manufacturers are Q CELLS, Panasonic, Jinko Solar, Trina Solar, and LONGi Solar panels.
If you are curious about JA solar panels in Dubai, talk to your installer to choose the best option for your specific roof’s solar installation. Whichever model you choose, standard versus half-cut, going with a reliable manufacturer and well-known local installers is your best option. So, ask your installer about the JA Solar 545W price.
Is JA Solar 545W panels the future of solar?
JA 545W panels are truly great for enhancing the solar power energy output of panels, but they are more difficult to manufacture. This makes it difficult for conventional manufacturers to switch to building half-cell solar modules, it is not as easy as just adding half-cut cells to a production line.
In many cases, conventional solar panels can still work for you, like if your roof has enough sunlight during the day.
