If you are looking for a place to buy wholesale solar panels, you’ve found it. A1 SolarStore offers PV modules from all over the world for competitive prices and with fast delivery. Let us tell you a little about the panels that we offer, how we deliver them and what kind of solar panel you might need.
There are three most popular types of solar panels on the market: monocrystalline, polycrystalline and thin-film. Monocrystalline or mono panels are the most reliable and efficient type, polycrystalline or poly panels are slightly cheaper, but less productive. Thin-film panels or flexible panels are special in a way that they are very light and bend well.
Monocrystalline panels are easy to distinguish by the black color of the cells. Their efficiency today varies from 16 to 22%, which means that mono solar cells convert into direct current from 16% to 22% of the sunlight that they receive. That’s the most popular type of panels — in fact, most top manufacturers don’t even sell anything else.
Polycrystalline panels are usually blue in color. They were dominant on the market 10-20 years ago, but today they slowly fade away. The reason for this is their low efficiency: 13%-17%. Manufacturing process is cheaper than it is with mono panels, but lower cost doesn’t quite justify low production levels. However, some brands still like to experiment with them and include them in their product line — for example, Canadian Solar offers both wholesale mono and polycrystalline solar panels.
Thin-film panels are a special thing. They are cheap and very easy to install, because they bend well and their weight is small. However, they are inefficient and their lifespan is considerably shorter than the lifetime of rigid panels. Usually, a flexible panel lasts for 10-15 years. They are quite popular in mobile installations, such as RV and boat systems. Because of their low price, wholesale lightweight solar panels can be a good choice for large projects, especially when the configurations of a surface make it difficult to install rigid modules.
While China is an undeniable leader on the solar market, the companies from all over the world offer competitive solar products and we keep the best of them in stock. So what are the most popular and reliable solar panels wholesale suppliers? Let’s take a quick look at a few brands.
Panasonic is one the oldest and most well-known brands in electronics. The Japanese company gained a great reputation over the years. Photovoltaic panels from Panasonic are very high quality, packed with innovations and are known for outstanding performance at high temperatures.
The Canadian brand was founded by Chinese scientist Dr. Shawn Qu. The panels that the company offers for sale aren’t too expensive, but they are quite powerful and perform well in low-light conditions, such as cloudy days, winter and fall.
This Chinese company competes in the Top-5 world’s largest solar brands. The panels from Trina Solar hold several world records for being the most efficient and productive. At the same time, the Chinese brand manages to keep the prices relatively low.
Norwegian brand REC is known primarily for its premium-class residential PV modules. However, it doesn’t limit itself to this: the product line is wide enough that you can use wholesale REC solar panels for building a strong commercial system, small or large. REC products are known for high quality, great warranties and innovations.
The Chinese brand aims to be the largest solar brand in the world. JA Solar offers cheap, efficient, high output PV modules for all kinds of applications, but especially solar farms. For instance, JA Solar wholesale 500 Watt solar panels are a great choice for systems of a large scope. They feature simple design, low price and high output.
Solar panels can be very different in terms of cost, and several factors impact the final price, such as wattage, brand, type of panel, warranties, etc. Whatever brand you pick, its solar panel wholesale price is lower than retail, so you end up saving a lot. Notice that at A1SolarSolar when it comes to the wholesale price of a solar panel, we show the cost per watt rather than per pallet or per panel.
Generally, solar market prices can be described like this: Asian panels, especially Chinese ones, are the cheapest ones. The most popular brands here are JA, LONGI, Trina Solar, ZNShine and many others. Asian PV modules are known for high efficiency and often provide very high output, which makes them probably the most popular choice when it comes to wholesale solar panels for sale for systems of a larger scope. However, their warranties for products are lower and quality issues are more frequent in comparison to US and European companies.
US manufacturers offer solar panels for a medium price. American PV modules aren’t always the most modern and they sometimes lack efficiency in comparison to the most advanced Chinese models. However, the quality is there and the panels are sturdy and resilient. You could say that US brands are a good middle-of-the-road choice. Among the most popular USA brands of wholesale solar panels we could mention Mission Solar, Canadian Solar and Silfab.
There are also a few brands that offer premium-class PV modules for home installations. These include Panasonic Eco Solutions, LG, SunPower, REC, Solaria and a few others. Generally, it doesn’t make much sense to build commercial systems out of them — they are too classy and expensive for that. However, you might save quite a lot by opting to go for their wholesale solar roof panels. They often come with the best warranties on the market, have great design and withstand all kinds of harsh weather — a great choice for your home.
Our customers use solar panels for residential, commercial and industrial projects — solar energy proves to be a reliable and efficient tool in different circumstances. The panels that are used in home and business systems differ in their output, size and type of installation. Let’s go over the basics.
Generally, homeowners pick panels in the 300 to 370 Watt power range. For example, a 350 watt panel is a very popular choice for home installations. The average size of a residential system in the USA is 5-6 kW, so you usually need around 17-25 modules to power your home appliances with solar.
When it comes to commercial and industrial systems, customers tend to go for wholesale high power solar panels. 500 watt panels or even more powerful ones is a common thing in large solar projects and solar farms. That’s only natural: the energy needs of enterprises are huge and there is no reason not to maximize the power output per square foot when you want as much energy as possible.
Panels for home systems usually have 60/120 cells. They are relatively small and it's easier to fit them on a house roof. Their dimensions are about 39 x 66 inches. A 120-cell panel is the same size as 60-cell panels because of the half-cut cell technology. Generally all panels with 300-370 Watts of power have 60/120 cells.
In systems of a larger scope 72/144-cell and 96-cell are used more often. Usually, space constraints are less of a problem with commercial systems, therefore there is no reason not to pick up larger panels with higher power output. 72/144 cell panels are approximately 39 x 77 inches in size.
400 watt wholesale solar panels are an interesting case. They are the middle-of-the-road choice and you can often see them both in residential and commercial installations. They often have 66/132 cells and their dimensions vary from 39 x 71 to 39 x 77 inches.
The majority of home solar systems are installed on the roof. It’s only natural: homeowners rarely use roof space for anything else. Larger systems are often ground-based, since massive energy production with powerful wholesale solar panels is a priority. Small and medium commercial systems are often installed on a flat roof, which makes a system similar to a ground-based one.
Almost all installations of a large scope (>10-15 kW) are grid-tie, which means that they are connected to the grid. An owner of a grid-tie installation is free to use commercial electricity, but he also can pump his excess solar energy into the grid and gain credits from his electric utility. When systems get large, it becomes too expensive to add batteries for support.
The majority of residential systems are grid-tie as well, but going off-grid is a reasonable option here. It makes sense when power outages are too frequent or there are no power lines available. A solar system can become the only source of energy for a house in a remote location: PV modules power the appliances during the day and at night you rely on energy storage. Just a couple of batteries is usually enough to back up a small size solar system.
You might be wondering — how exactly are we going to deliver the pallet? A1 SolarStore has a distribution network throughout continental US. We work with the top freight carriers XPO, FedEx, ODFL, R&L etc. The panels are shipped with LTL/Freight service. Freight orders are delivered in a manner called ‘curbside delivery’, which generally means that the carrier delivers the pallet to the end of your driveway.
Important things to remember:
Alongside wholesale solar panels for your home and business, we also ship batteries, inverters, charge controllers and addons with FedEx Ground.
When you receive a shipment or grab your order at our fulfillment center, it’s important to remember a few guidelines about how to carry and move solar panels around.
When you carry a panel, try not to apply too much pressure in one spot. Distribute the weight of a module across your shoulder, arm and back. The installation process should be handled by professionals. Generally, they use a mechanical lift to get the panels up on the roof and some workers use a ladder instead.
If you want to grab the panels yourself at one of our fulfillment centers, leave a note "palletized order" in request comments. The pallet is a bit bigger than a panel and it might not fit in the back of every car. If you want to take the panels as they are, prepare some sort of packaging to minimize the risk of cracking the module. You can use foam pads, bubble wrap, and even blankets. Don't put anything on top of the panels!
So where to buy solar panels wholesale? A1 SolarStore is a great choice for several different reasons.
All of this makes A1 SolarStore the best place to buy solar panels wholesale. Our staff is ready to help you with your purchase and answer all of your questions about delivery, warranties and availability.
Frequent power outages, high electricity bills, and the growing need for clean and renewable energy are a few reasons that force homeowners to go solar. Solar panels attached to a battery help homeowners use the solar energy, convert it into electricity, and use it to power up appliances per their needs.
Solar panels are an excellent way to power your home, off-grid living and save money, but many types of solar panels available make it hard for them to make a better choice.
This guide will include everything you need to know, from choosing the right type of solar panels and going "green" to understanding how they work to power your house. Most common solar panels include monocrystalline, polycrystalline, and thin film. Let us discuss them in detail.
Solar panels are photovoltaic or PV cells that absorb sun rays and convert them into electrical energy. The typical solar panel consists of silicon, boron, and phosphorus layers.
The boron layer provides a positive charge, whereas the phosphorus layer provides a negative charge. The internal layer between boron and phosphorus is silicon, which acts as a semiconductor.
The silicon cells release electrons and create an electrical current. The released electrical current stored in the battery is then used to power electrical gadgets and devices during power outages or outdoor adventures.
Solar panels are undoubtedly an ideal means to cut connections from the grid and use solar energy. But have you ever thought about how these solar panels work to generate electrical energy and power your entire house?
Solar panels use sunlight as their fuel to generate power/energy. When sunlight strikes the panels, the surface converts the sunlight into electricity. Solar panels are composed of cells that contain electrons. The negative charge of boron and the positive charge of phosphorus creates a magnetic field.
The falling sunlight on the cells destabilizes the electrons and frees up the negatively charged electrons. The movement results in the production of current or electricity. However, this electrical current is not suitable for home appliances. And this is where the role of the solar inverter starts.
The solar inverter converts the produced electricity from DC to AC so you can charge up your appliances.
One important thing to remember is that solar panels only work when they receive direct sunlight. The more peak sunlight it gets, the higher the electricity production. For this reason, a solar panel produces more solar energy during sunny days than on cloudy days.
There are four main types of solar panels: monocrystalline, polycrystalline, PERC, and thin-film. Depending upon the type of solar cells, the solar panels are categorized into different categories, shown in the table below.
Let us discuss the four types of solar panels in detail.
Best known as single-crystal panels, monocrystalline solar panels are made using a pure form of silicon crystals. The crystal is sliced into multiple octagonal-shaped wafers forming cells.
The monocrystalline solar panels are built on the Half Cut cells technology. Within the solar panels, the square-shaped cells are cut to produce twice the number of cells.
The cells in the two halves of the solar panels are connected in two different series, ensuring consistent power generation even if there is a shadow on half panel.
Features of Monocrystalline Solar Panels
Pros
Cons
Also called multi-crystalline panels, these solar panels are typically cheaper than monocrystalline solar panels. This is because silicon fragments manufacture solar cells instead of pure silicon crystals.
A simple manufacturing process reduces the overall cost of the solar panel. However, in terms of space and energy conversion, they are less efficient and have lower heat tolerance.
Features Of Polycrystalline Solar Panels
Pros
Cons
Thin-film solar panels have lower efficiency ratings, so they are usually used in large-scale utility or industrial solar installations.
It is produced by depositing a layer of photovoltaic substance, such as copper indium gallium selenide (CIGS), amorphous silicon (a-Si), or cadmium telluride (CdTe), on glass.
You will get efficient and thoughtful service from Shanghai Gulier.
Even though each material creates a different solar panel, they all fall under thin film solar cells.
Features Of Thin-Film Panels
Pros
Cons
Passivated Emitter and Rear Cell (PERC cells) is a new technology that involves adding a passivation layer to the rear cell surface. The latest technology in PERC solar panels increases the amount of absorbed solar radiation by reflecting light back into the cell.
The energy collection is high in PERC panels, so it is ideal for limited space. However, they are a little expensive compared to traditional solar panels.
Features of PERC Solar Panels
Pros
Cons
Besides common types of solar panels, there are a few less-known solar panel cells, including:
As the name suggests, bifacial solar cells can absorb light on both sides and convert it into energy.
The backside of the panel absorbs light that's reflected from the ground. You can consider placing a mirror behind these cells for maximum electricity production.
Studies reveal that bifacial models can produce 10-20% (Data from pv-magazine) more power than traditional or mono-facial panels — however, the efficiency comes at a cost. You have to pay nearly 15% more than mono facial solar panels for higher efficiency and power.
Unlike solid solar panels, transparent panels are built using see-through quality. It works like a regular panel but has a slight or complete see-through ability.
It's important to note that these solar panels are mostly suited for commercial contexts rather than residential ones. In addition, they are not portable, making them less suitable for outdoor adventurers.
Solar tiles and solar roof tiles work on the same concept — they help convert sunlight into electricity. The appealing aesthetic is the only reason people choose solar roof tiles over solar panels.
But before you plan to invest in solar roof tiles, note that they could cost you twice as much as solar panels. Furthermore, they are less efficient when converting sunlight into electricity.
Not all panels are the same when we talk about efficiency, performance, costs, and other factors. Here is how they differ.
Efficiency is one of the most important deciding factors when choosing a solar panel type. Here is how efficiency differs depending on the solar panel you choose.
Power capacity depends on how much power the solar panel can produce during peak hours.
Here is the breakdown of how different types of solar panels differ in appearance.
If you are ready to go solar, understanding the cost associated with the solar panel purchase is critical.
Note - This is the general cost estimation for each type. The accurate expense related to the solar panels will depend on other factors such as brand, electricity requirements, size, etc.
Beyond the cost and efficiency of solar panels, a few factors impact the choice of solar panels.
If your home area is prone to hail or snow, it's better to look for a solar panel that can withstand hail hitting without damage. Monocrystalline and polycrystalline panels are manufactured using thick materials. Therefore, they are a reliable choice for homeowners living in hail-prone areas.
Light-induced degradation, or LID, is the solar panel degradation that occurs during the first few hours of sun exposure. The higher the LID rate of a solar panel, the lower the quality. Therefore, choosing a solar panel with a LID below 3% is preferable for maximum output.
Electricity generation and the temperature of solar panels are related to each other. Make sure to check the temperature coefficient of the solar panel before making your purchase. It should range between - 0.2% °C to - 0.5% °C, so you get the maximum power output. Jackery solar panels have a good performance in hot and cold weather, the working temperature is -10-65°C (14-149°F). Each time the temperature rises by 1℃, the conversion efficiency still be 28.5% higher than alternatives on the market.
