Their list of product offerings include items such as silicon wafers, solar cells, solar panel modules, and other solar energy components.<\/p>\n<p>In terms of solar panel options, JA Solar has a number of variations for the customer to choose from. With the ability to get different power outputs, solar cell counts, and solar cells types, JA Solar offers a great level of flexibility that earns them a spot as a <a href=\"https:\/\/www.solar.com\/learn\/best-solar-panels\/\" rel=\" noopener\">top solar panel<\/a> on our reviews.<\/p>\n<p>To make it easier to understand, we&#8217;ll break down JA Solar\u2019s solar panel offerings into simple categories and explore the details of each solar panel that falls within.<\/p>\n<h2>JA Solar Standard Solar Module Information<\/h2>\n<p>The standard JA Solar panels for sale come with either <a href=\"https:\/\/www.solar.com\/learn\/monocrystalline-solar-panels-polycrystalline-comparison\/\" rel=\" noopener\">polycrystalline or monocrystalline<\/a> solar cells. Polycrystalline solar cells are manufactured differently from monocrystalline, and as a result, have different features.<\/p>\n<p>Polycrystalline solar panels are produced by filling a mold with silicone and allowing it to set into a wafer. The uneven texture of these cells leads to many silicon crystals forming, which gives these panels a sparkling look. They are also blue in appearance.<\/p>\n<div><\/div>\n<p>M<span style=\"background-color: transparent; font-size: 19.2px;\">onocrystalline cells are produced through a much more involved process, which leads to higher efficiency solar cells and thus a higher cost than polycrystalline. These panels are also black in color.<\/span><\/p>\n<p>JA Solar\u2019s standard solar modules also come in a 60-cell or 72-cell count. Here is a table to outline the differences in power output and efficiency for these modules:<\/p>\n<p>&nbsp;<\/p>\n<table border=\"1\" cellpadding=\"5\">\n<tbody>\n<tr>\n<td><strong>Solar Panel Module<\/strong><\/td>\n<td><strong>Max Power Output (Pmax)<\/strong><\/td>\n<td><strong>Efficiency<\/strong><\/td>\n<\/tr>\n<tr>\n<td>60-Cell Poly (JAP60S01\/SC)<\/td>\n<td>280 W<\/td>\n<td>17.1%<\/td>\n<\/tr>\n<tr>\n<td>72-Cell Poly (JAP72S01\/SC)<\/td>\n<td>335 W<\/td>\n<td>17.2%<\/td>\n<\/tr>\n<tr>\n<td>60-Cell PERC Mono (JAM60S01\/PR)<\/td>\n<td>310 W<\/td>\n<td>19.0%<\/td>\n<\/tr>\n<tr>\n<td>72-Cell PERC Mono (JAM72S01\/PR)<\/td>\n<td>335 W<\/td>\n<td>17.2%<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<p><span style=\"background-color: transparent; font-size: 19.2px;\">Outside of power output and efficiency, there are a few other features that differentiate these solar modules.<\/span><\/p>\n<p>JA Solar\u2019s standard panels have limited power degradation. All solar panels degrade over time from weathering, but some panels degrade slower than others. Also, each one of these modules has a high salt mist, Sand dust, and ammonia resistance, which allows you to install it in a number of climates.<\/p>\n<p>These models have higher efficiency due to a lower <a href=\"https:\/\/www.solar.com\/learn\/does-solar-panel-temperature-coefficient-matter\/\">temperature coefficient<\/a>, but the monocrystalline models have a much better performance in low-light environments. Lastly, each of these modules have 5 busbars to further help with their efficiency.<\/p>\n<h2>JA Solar Half-Cell Module Review<\/h2>\n<p>In case you need a quick review, each solar module (aka solar panel) is composed of individual solar cells, the little square components within panels.\u00a0<span style=\"background-color: transparent; font-size: 19.2px;\">JA Solar\u2019s half-cell solar panels are unique in that their solar cells are smaller in size than the standard model.<\/span><\/p>\n<p><img style=\"width: 327px; display: block; margin: 0px auto;\" src=\"https:\/\/assets.solar.com\/wp-content\/uploads\/JA%20Solar%20Half-Cell%20Module.jpg\" alt=\"JA Solar Half-Cell Module\" width=\"327\" \/><\/p>\n<p style=\"text-align: center;\"><em><span style=\"font-size: 14px;\">JA Solar&#8217;s Half-Cell Modules<\/span><\/em><\/p>\n<p><span style=\"background-color: transparent; font-size: 19.2px;\">This results in higher power outputs, lower temperature coefficients, reduced shading effect on the module\u2019s energy production, lower risk of hot spots, and an improvement in tolerance for mechanical loading.<\/span><\/p>\n<table border=\"1\" cellpadding=\"5\">\n<tbody>\n<tr>\n<td><strong>Solar Panel Module<\/strong><\/td>\n<td><strong>Max Power Output (Pmax)<\/strong><\/td>\n<td><strong>Efficiency<\/strong><\/td>\n<\/tr>\n<tr>\n<td>60-Cell Poly Half-Cell (JAP60S03\/SC)<\/td>\n<td>290 W<\/td>\n<td>17.4%<\/td>\n<\/tr>\n<tr>\n<td>72-Cell Poly Half-Cell (JAP72S03\/SC)<\/td>\n<td>345 W<\/td>\n<td>17.4%<\/td>\n<\/tr>\n<tr>\n<td>60-Cell PERC Mono Half-Cell (JAM60S03\/PR)<\/td>\n<td>320 W<\/td>\n<td>19.2%<\/td>\n<\/tr>\n<tr>\n<td>72-Cell PERC Mono Half-Cell (JAM72S03\/PR)<\/td>\n<td>335 W<\/td>\n<td>17.2%<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><span style=\"background-color: transparent; font-size: 19.2px;\">As you can see from the above table, the half-cell modules all come in the same models as the standard. So, the only difference is what results from the half-cells. <\/span><\/p>\n<p><span style=\"background-color: transparent; font-size: 19.2px;\">Additionally, when it says 60-cell, there really are 120 individual cells, since the 60 original cells are split in half. Same goes for the 72-cell models.<\/span><\/p>\n<h2>Double Glass Module<\/h2>\n<p>The double glass modules have a different backsheet than the traditional polymer ones. These units are covered with heat-strengthened glass that leads to lower power degradation and higher productivity in all types of environments.<\/p>\n<p style=\"text-align: center;\"><img style=\"width: 327px; display: block; margin: 0px auto;\" src=\"https:\/\/assets.solar.com\/wp-content\/uploads\/JA%20Solar%20Double%20Glass%20Panel.jpg\" alt=\"JA Solar Double Glass Panel\" width=\"327\" \/><\/p>\n<p style=\"text-align: center;\"><em><span style=\"font-size: 14px;\">JA Solar&#8217;s Double Glass Modules<\/span><\/em><\/p>\n<p>Overall, the double glass feature makes these modules more durable and reliable. They also come in the four options as the previous JA Solar panels. One notable difference is that the 72-cell monocrystalline panel has a much higher output and efficiency.<\/p>\n<table border=\"1\" cellpadding=\"5\">\n<tbody>\n<tr>\n<td><strong>Solar Panel Module<\/strong><\/td>\n<td><strong>Max Power Output (Pmax)<\/strong><\/td>\n<td><strong>Efficiency<\/strong><\/td>\n<\/tr>\n<tr>\n<td>60-Cell Poly Double Glass (JAP60D00\/SC)<\/td>\n<td>280 W<\/td>\n<td>17.0%<\/td>\n<\/tr>\n<tr>\n<td>72-Cell Poly Double Glass (JAP72D00\/SC)<\/td>\n<td>335 W<\/td>\n<td>17.2%<\/td>\n<\/tr>\n<tr>\n<td>60-Cell PERC Mono Double Glass (JAM60D00\/PR)<\/td>\n<td>310 W<\/td>\n<td>18.8%<\/td>\n<\/tr>\n<tr>\n<td>72-Cell PERC Mono Double Glass (JAM72D00\/PR)<\/td>\n<td>370 W<\/td>\n<td>19.0%<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>These glass backsheets are not transparent. Those kinds of modules are called bifacial &#8211; which JA Solar also offers.<\/p>\n<p><span style=\"color: #253e5a; font-family: montserrat, sans-serif; font-size: 24px; font-weight: 600; background-color: transparent;\">Bifacial Mono PERC Double Glass Module<\/span><\/p>\n<p>The final category of solar panel modules that JA Solar has to offer are the Bifacial Mono PERC Double Glass modules. There are also 4 options within this category \u2014 two 60-cell options and two 72-cell options.<\/p>\n<p><img style=\"width: 960px;\" src=\"https:\/\/assets.solar.com\/wp-content\/uploads\/Blog%20Image%20Sketches%20(15).png\" alt=\"Front and Back of JA Solar Bifacial Modules\" width=\"960\" \/><\/p>\n<p style=\"text-align: center;\"><em><span style=\"font-size: 14px;\">Front and Back of JA Solar&#8217;s Bifacial Modules<\/span><\/em><\/p>\n<p>JA Solar\u2019s bifacial PERCIUM cells have the ability to generate energy on both sides of the panel. This leads to higher-performing and more cost-effective modules. This also helps with its durability and longevity.<\/p>\n<p>The only difference between the two models for each cell size is that one of them has a 30mm frame added to it. This makes it easier to transport and install. Here are the other details:<\/p>\n<table border=\"1\" cellpadding=\"5\">\n<tbody>\n<tr>\n<td><strong>Solar Panel Module<\/strong><\/td>\n<td><strong>Max Power Output (Pmax)<\/strong><\/td>\n<td><strong>Efficiency<\/strong><\/td>\n<\/tr>\n<tr>\n<td>60-Cell Bifacial Mono PERC Double Glass\u00a0(JAM60D00\/BP)<\/td>\n<td>310 W<\/td>\n<td>18.7%<\/td>\n<\/tr>\n<tr>\n<td>72-Cell Bifacial Mono PERC Double Glass (JAM72D00\/BP)<\/td>\n<td>370 W<\/td>\n<td>18.8%<\/td>\n<\/tr>\n<tr>\n<td>60-Cell w\/ 30mm Frame (JAM60D00\/BP)<\/td>\n<td>310 W<\/td>\n<td>18.5%<\/td>\n<\/tr>\n<tr>\n<td>72-Cell w\/ 30mm Frame (JAM72D00\/BP)<\/td>\n<td>370 W<\/td>\n<td>18.6%<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><span style=\"color: #253e5a; font-family: montserrat, sans-serif; font-size: 24px; font-weight: 600; background-color: transparent;\">Is JA Solar Right For Me?<\/span><\/p>\n<p>From the above tables, you can see that the power output and efficiency of JA Solar\u2019s modules are very comparable with the majority of <a href=\"https:\/\/www.solar.com\/learn\/top-5-solar-panels-selected-through-solar-dot-com-in-2017\/\">other solar panels on the market<\/a>. It is very common to see panels around 15-16% efficiency on the low end and 18-19% on the high end, although some solar panels can reach an efficiency of over 21%.<\/p>\n<p>All of JA Solar\u2019s panels are quite durable and have 10-year product quality warranties and up to 25-year power output warranties.
