Mono Crystalline Solar Modules

Monocrystalline solar panels are one the most efficient commercially viable photovoltaic solar collectors!

Monocrystalline solar panel has been the go-to choice for many years, and is among the oldest, most efficient, and most dependable of technologies. Each module is made from a single silicon crystal, and is more efficient, though more expensive, than the newer and cheaper polycrystalline types. Monocrystalline Solar panels also called solar modules is an collection of small solar cell spread over a wide area working together to provide maximum useful solar power. The more light that hits a cell, the more electricity it produces. The cells of a monocrystalline solar module are cut from a chunk of silicon that has been grown from a single crystal that grows in only one direction or plane. Monocrystalline solar panels are more efficient in converting the sun€™s rays to electricity. Choosing between monocrystalline and polycrystalline solar cells is not easy. Both are made from crystalline silicon, the most efficient semiconductor material on the market today, but in different waves. A monocrystalline panel is made of individual silicon wafers all cut from the same cylindrical ingot. Polycrystalline panels, sometimes referred to as multicrystalline, are made from cast square ingots of silicon produced by cooling and solidifying molten silicon. Determining which is better requires weighing cost against efficiency. Monocrystalline solar cells are the most efficient, readily available ones to date. The best reach 22 percent conversion efficiency in the real world. Polycrystalline cells are less efficient, although higher than thin-film solar cells for now, but cost less to manufacture than the single-crystal monocrystalline.

When putting together a long term solar setup and want the best and most reliable panels on the market, monocrystalline types are probably the best bet. They€™re costlier than polycrystalline options, but their longevity, performance, and efficiency mean that they€™re a good buy over a longer period of time. When you want to be sure you€™re producing the highest wattage per square foot, these are the modules to rely on.

We have wide selection of monocrystalline solar panels that will give you maximum output at very great prices.

These are generally considered the workhorses of the solar power market because they€™re made from just one crystal, not multiple crystals fused together; the process of making them is one of the most complex and costly however, that increased cost is buying additional efficiency, meaning one panel will produce more power than lower priced options. If space is a concern (which it often is with solar panels), monocrystalline will be the best type to use. More wattage per square foot can be delivered with these panels. The lifespan of a monocrystalline cell is a minimum of twenty-five years and can be more than fifty, making them a worthwhile investment for long term use.

Q. What is the difference between a monocrystalline vs. polycrystalline photovoltaic cells?

A. You have heard the terms monocrystalline and polycrystalline used to describe photovoltaic cells, but what does that mean and how does it affect a cell€™s performance? The main ingredient in most photovoltaic cells is silicon €“ the same element that makes computer chips possible. Silicon is the second most abundant element in the Earth€™s crust, but unfortunately it is normally found in the form of silica (the chemical symbol for silica is SiO2) €“ you might know it as sand.Various methods exist to extract the pure silicon, but the most common is carbothermic reduction, where the silica is heated to 1700°C in the presence of carbon. As the silicon cools it forms crystals. The speed at which the silicon cools is one of the critical factors that determine the crystal size: the slower the silicon cools, the larger the crystals. With care the silicon can be extracted as one large crystal. As you might imagine, that€™s more difficult, which means it€™s more expensive. The difference between monocrystalline vs. polycrystalline solar cells is simply that one is produced from a single crystal of silicon and the other is produced from a piece of silicon consisting of many crystals.

Q. What is the impact on the cells performance?

A. Since polycrystalline cells contain many crystals, they have a less perfect surface than monocrystalline cells. This means that they absorb slightly less solar energy and produce slightly less electricity per square meter. On the plus side, the process of creating the silicon for a polycrystalline cell is much simpler, so these cells are generally cheaper per square meter. On balance, the cost of monocrystalline vs. polycrystalline based panels per Watt of power output works out about the same, but the polycrystalline panels will be slightly larger than equivalent monocrystalline panels. This is generally not a problem unless you have a very limited area available for the installation, in which case you will want to maximize the power output per square meter. Monocrystalline and polycrystalline can also look different. Monocrystalline cells will usually have a perfectly uniform appearance, but polycrystalline cells will appear €œgrainy€ €“ think of how a granite worktop looks and you€™ll get the idea. From a distance this will not be noticeable, so if they are going on your roof this is unlikely to worry you.

Q. Which do I choose?

A. At the end of the day, unless you are very space constrained, your choice of panel will probably be dictated by factors other than whether they are made up of mono or polycrystalline cells. The price per Watt is an important factor, and that is largely unaffected by the choice of monocrystalline versus polycrystalline cells. In some circumstances, the area available for the installation may be a factor that pushes you to go for monocrystalline cells.

Q. Is there a difference in Pricing?

A. Monocrystalline solar cells cost more than polycrystalline for the same size.

Q. Which is more efficient?

A. Monocrystalline cells have a higher efficiency than polycrystalline cells due to the structure being made from one large crystal as opposed to many small ones. In addition to having an overall better efficiency, monocrystalline panels can perform up to 10% better than polycrystalline panels in high ambient temperatures and since monocrystalline panels are more efficient per area, the size of the solar panel is less than a polycrystalline solar panel for the same wattage. If you are limited on size and want to get the most energy possible, monocrystalline panels are the better choice.

Q. Which is more aesthetically pleasing?

A. In terms of looks, monocrystalline panels have a nice uniform color and have a more circular cell shape. Polycrystalline cells are in squares and have inconsistencies in the color sort of like granite.

Q. Which type last longer?

A. Monocrystalline panel has the potential to last up to 50 years, even though most warranties only go up to 25 years while polycrystalline panels are able to last just over 30 years.
