If you are looking for a place to buy wholesale solar panels, you’ve found it. A1SolarStore 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.

Three types of solar panels

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.

Popular brands of solar panels

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

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.

Canadian Solar

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.

Trina Solar

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.

REC

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.

JA Solar

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.

How much do wholesale solar panels cost?

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.

Commercial and residential systems

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.

Power output

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.

Size

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.

Installation type

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.

Shipping

You might be wondering — how exactly are we going to deliver the pallet? A1SolarStore 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:

  • You’ll have to climb into the truck and unload the pallet and all boxes for the order yourself. A liftgate can be used to take the pallet off the truck and lower it to the ground level. However, this is considered to be extra service — you’ll have to order and pay for it in advance.
  • The carrier is not responsible for delivering the pallet up your driveway or onto your property.

Alongside wholesale solar panels for your home and business, we also ship batteries, inverters, charge controllers and addons with FedEx Ground.

How to carry solar panels

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!
