Where Are Most Solar Panels Manufactured

Does It Matter Where Solar Panels Come From

We have examined some of the most remarkable solar panels made in the USA, however, you may find other brands such as SunSpark, Kyocera Solar, Centro Solar America, Mage Solar, and Zebra Energy, that also manufacture their solar panels inside the US.

Quality of US manufactured products is generally indisputable. However, that does not mean that you cannot find premier and high-quality modules that are manufactured outside the US.

For example, Sunpower has its headquarters inside the US but manufactures in China and the Philippines, and they have been the worldwide top brand for several years. Jinko Solar, LG, and Trina Solar are other examples of high quality standard solar panels that are not manufactured inside the US.

If you opt for US solar panels due to patriotic reasons then thats perfect! But if not, do some research to find a balance between quality, design, and costs!

Why Should You Care About Solar Panel Efficiency

The efficiency value is directly related to the power rating and the size of the solar panel. Lets imagine we have a panel with a specific size and power output. If we increase the efficiency, then it means the panel will need less space to produce the same amount of power. In other words, the module will have the same size, but its power output will be bigger.

On the other hand, if we reduce the efficiency of the solar panel, then it means that the PV system will need to cover more space since the solar panel will have the same size but will have a lower power output. Therefore, selecting the appropriate panel model according to the efficiency rating can have a significant impact on the power output of your PV system, drive important space reductions and, increase annual energy yields.

Solar panels glimmering in the sun are an icon of all that is green. But while generating electricity through photovoltaics is indeed better for the environment than burning fossil fuels, several incidents have linked the manufacture of these shining symbols of environmental virtue to a trail of chemical pollution. And it turns out that the time it takes to compensate for the energy used and the greenhouse gases emitted in photovoltaic panel production varies substantially by technology and geography.

That’s the bad news. The good news is that the industry could readily eliminate many of the damaging side effects that do exist. Indeed, pressure for it to do so is mounting, in part because, since 2008, has moved from Europe, Japan, and the United States to China, Malaysia, the Philippines, and Taiwan today nearly half the world’s photovoltaics are manufactured in China. As a result, although the overall track record for the industry is good, the countries that produce the most photovoltaics today typically do the worst job of protecting the environment and their workers.

The paper’s investigation, , profiled a Chinese polysilicon facility owned by Luoyang Zhonggui High-Technology Co., located near the Yellow River in the country’s Henan province. This facility supplied polysilicon to Suntech Power Holdings, at the time the world’s largest solar-cell manufacturer, as well as to several other high-profile photovoltaics companies.

From Solar Cell To Solar Panel

The solar cells are soldered together, using metal connectors to link the cells. Solar panels are made of solar cells integrated together in a matrix-like structure. The current standard offering in the market are:

• 48 cell panels – suitable for small residential roofs.

• 60-cell panels – this is the standard size.

• 72-cell panels -used for large-scale installations.

The most common sized system in terms of kWh for UK homes is the 4kWh solar system.

After the cells are put together, a thin layer of glass is added on the front side, facing the sun. The backsheet is made from highly durable, polymer-based material. This will prevent water, soil, and other materials from entering the panel from the back. Subsequently, the junction box is added, in order to enable connections inside the module.

It all comes together once the frame is assembled. The frame will also provide protection against impact and weather. The use of a frame will also allow the mounting of the panel in a variety of ways, for example with mounting clamps.

EVA is the glue that binds everything together. It is very important that the quality of the encapsulant is high so it doesn’t damage the cells under harsh weather conditions.

Top Solar Panel Manufacturers Worldwide

Its not surprising that the business of harvesting solar energy is growing exponentially when the metrics of its growth in the past few years are considered.

Especially in the emerging market of China, which currently is the most profitable market for solar energy and has cities in which solar energy is already cheaper than grid electricity.

Most of this electricity is produced by newer and more modern solar panels that are both more efficient and less hazardous for the environment.

There are always new metals and other materials that can more efficiently turn sunlight into DC electricity and, eventually, into the standard AC electricity most electronics use.

With these two facts in mind, all that is left to be asked is: Which companies are the largest Solar Panel Manufacturers in the world?

Luckily for you, my dear reader, I present to you ten of the most prominent players in the manufacturing industry as of the current year, 2021, of course.

Will The Us Become A Major Player In Solar Manufacturing

Whether the US will become a major player is yet to be seen. The Trump administration levied a 30% solar tariff on some solar cells, and the Biden administration has backed them. Tariffs are not a new concept as we know, the idea is to incentivize companies to manufacture products domestically rather than import them.

Whether Trumps tariffs were more about incentivizing domestic production or more due to has vendetta against China is anyones guess, but more manufacturing here in the US could be a good thing.

As the Harvard Business Schools Gary Pisano noted, sending solar production offshore could lead to a loss of innovation. This actually makes quite a bit of sense: if the US isnt manufacturing, it probably isnt innovating, either.

Although many people argue against tariffs generally, saying companies will just get their imports from countries that dont have tariffs, that may prove difficult for solar panels. After all, China is still producing the vast majority of them globally. Thus, if importing them is too expensive, then domestic production may become a necessity.

Whether that will actually come to pass is anyones guess. However, more innovation is needed in order for solar energy to really take over. Increases in solar panel efficiency and decreases in cost would go a long way toward making that happen.

Should You Make Your Own Solar Panels

We do not recommend making your own solar panels, although it might seem easy to configure a panel with all of the proper materials. Errors in building your own panels, like starting a fire, outweigh the benefits of DIY solar panels.

It is best to rely on professionally built solar technology because they are built with rigorous standards and tested for durability. Working with a professional solar installer is an important step to making sure your solar panels are made with high-quality materials that will provide solar power for their 25-year warranty, or more. Solar panels are one of the best energy sources for reducing carbon dioxide from fossil fuels so adding them to your home is a great way to be part of the clean energy future.

Where Does Polysilicon Come From

Polysilicon has one origin: silica. Silica is mined from the earth and is found in sand, rock, and quartz. Because silica has a dioxide component, it must be taken to a plant, where it is converted to silicon through a heating process. According to the United States Geological Society, there are six domestic companies that produce silicon materials at eight plants. These are all located east of the Mississippi River. Imported silicon comes from all around the world, including China, Russia, Japan, Brazil, South Africa, Canada, Australia, and others.

What Solar Panels Are Made In Australia

As Ozzys, we are quite a patriotic breed. We believe we have the best beaches, the best weather and the best overall lifestyle of anywhere in the world. I certainly do anyway! As patriotic individuals we also like to support our fellow people as much as possible, including buying Ozzy made and using Ozzy companies wherever possibleas long as it doesnt hurt too much

Since mid 2020 the question do you install any Australian Made solar panels has been asked way more frequently. Partly due to Covid-19 we assume people all around the world realise now more than ever we need to protect what we have and support our neighbours as much as possible.

With that in mind we wanted to address all the relevant details around Australian Made solar panels as well as the other most commonly asked manufacturer location-based questions:

• What solar panels are made in Australia?
• What solar panels are NOT made in China?
• What solar panels are made in Germany?

A good place to start would probably to highlight that GI Energy are a 100% Australian Owned and Certified Business. All of our Directors are Australian Citizens, and all our profits, taxes and wages stay here in Australia. We do not import any products from overseas ourselves and the solar panels and other solar equipment we supply and install comes from distributors and manufacturers with Australian offices, telephone lines and support.

Now, to address the first question.

Most Efficient Solar Cells

The most efficient solar panels on the market generally use either N-type monocrystalline silicon cells or the another highly efficient N-type variation, heterojunction cells. Most other manufacturers currently use the more common P-type mono-PERC cells however, several large volume manufacturers, including JinkoSolar, Longi Solar and Trina, are now starting to shift to the more efficient N-type cells.

Solar Panels: Assembling Cells Into Useful Devices

Solar panel manufacturers employ different proprietary processes to produce their final solar panel products. But, in general, this is an automated process in which robots do the work. First, the cells must be put together to form a big sheet. According to Solar World, a leading manufacturer of solar panels, its process involves soldering six strings of ten cells each, making a rectangle of 60 cells. Each rectangular matrix is laminated onto glass and quickly becomes a larger panel. From there, the panel needs to be framed so that it is sturdy and protected from any weather it will endure.

In addition, the framing must house the electrical equipment that links the panels together and receives the energy.

What If The Country Of Manufacture Is Important To Me

This doesnt mean that country of origin is never important, of course: everyone has their own preferences. For example, many Americans would prefer solar panels made in the USA to ones that are imported, whether for patriotic reasons or because they trust the American-made brand for quality.

American-made vs imported panel costs

American-made solar panels generally cost from $0.50 to $0.80 per watt about $0.10 to $0.30 more per watt than imported panels. The highest quality, premium American panels may even come in around $1.00/W.

For a typical 6kW system, an additional $0.30/W translates into about $1,800, a reasonable amount to pay if the Made in America stamp is important to you. Also keep in mind that some states may offer rebates for locally-made panels that can offset some or all of the additional cost.

Check out our list of U.S. solar panel manufacturers for more information about companies that make solar panels in America.

Manufacturing location vs headquarters location

If country brand is important to you, be aware that the location of a companys headquarters is not always the same as its factories. All else being equal, knowing that a companys head office is relatively close or in a familiar country could help you make a decision.

Best Solar Panels For Low Light Or High Temperatures

The PVEL report also lists top performers in each test category, which can be useful if you want to buy a solar panel that does well in a specific category.

Low light and high temperature performance are two metrics that buyers often ask about. Low light performance isnt just an issue for installations in cloudy environments – low light is something that every solar installation experiences every day, in the morning and evening.

7 manufacturers made the top performers list in this category. Not all of them are common in the US residential market, but they include Jinko, Panasonic, and Trina Solar.
