Longevity Isnt Practically Affected
In theory, monocrystalline silicon is manufactured to a higher standard and will last longer than polycrystalline.
However, in practice, solar panels donât fail because of the silicon, but for other reasons. The number one reason is cracked glass, followed by other reasons such as damaged seals that allow moisture to creep in, potential induced degradation, and hot spots. Failure of the silicon itself isnât really an issue.
If you want to buy solar panels that last as long as possible, focus on getting solar panels with the longest product warranty. Solar panel warranties come in two parts: a product warranty that covers parts and manufacturing, and a power warranty that guarantees against power output loss. Panels that are manufactured to a higher standard will tend to come with a longer product warranty as much as 25 years, versus 10 years for cheap panels.
Monocrystalline Vs Polycrystalline Vs Thin
The first set of terms describes how solar cells are formed out of raw materials.
Traditional solar cells are made from silicon, a conductive material. The manufacturer shapes raw silicon wafers into uniformly-sized silicon cells.
Solar cells can either be monocrystalline or polycrystalline . Lets look at the differences between the two options.

Most Attractive: Thin Film Panels
Thin film panels have a clean, all-black look. Their thin design allows them to lie flat against roofs, so they are able to blend in more seamlessly. In fact, with some thin film panels, its hard to even see the individual cells within the panel. They also tend to have less wiring and busbars, meaning theres less white space.
However, because they are so inefficient, you would need to cover your entire roof in thin film panels which may or may not be your style.

Monocrystalline Vs Polycrystalline Solar Panel Lifespan
Most solar panels, whether monocrystalline and polycrystalline, have a lifespan of between 25 and 30 years. So, when choosing between the two, this will not be a crucial factor.
The lifespan of solar panels depends on their degradation, meaning their reduced output over time. The degradation between monocrystalline and polycrystalline panels is similar. More important factors include the climate in which you live, how well the panels were installed, how well theyre maintained, and the quality of the materials.
What Polycrystalline Solar Panels Are
Polycrystalline solar panels are made of individual polycrystalline solar cells.
Just like monocrystalline solar cells, polycrystalline solar cells are made from silicon crystals. The difference is that, instead of being extruded as a single pure ingot, the silicon crystal cools and fragments on its own. These fragments are melted in an oven and formed into cubes which are cut into thin wafers. So, many different crystals form this amalgam, rather than the single crystal of the monocrystalline solar cell type. Its a less exacting production process than with monocrystalline cells, so it allows for more solar cells to be produced faster and less expensively.
The blue-colored square polycrystalline cells fit neatly side by side, eliminating any empty space between the cells. Polycrystalline solar panels operate less efficiently than monocrystalline panels because the melted fragments of silicon afford less room for the electrons to move around.
Polycrystalline panels generally have an efficiency rating of between 13% and 16%. While only a few percentage points less than monocrystalline panels, its a difference that can count for a lot when compounded across many solar panels.

How Many Solar Panels Do You Need
When considering solar panel options, it is important to determine how many solar panels you will need to generate the amount of power output you desire. This will depend on a number of factors, including the efficiency of the solar panels, the size of your home, space constraints and your average energy consumption.
The first step is to calculate your homes energy consumption. This can be done by looking at your past energy bills. Once you have an estimate of your energy consumption, you can then determine how many solar panels you will need to offset this usage.
Efficiency is an important factor to consider when determining how many solar panels you need. More efficient panels will require fewer panels to generate the same amount of power as less efficient ones. Solar panel efficiency is measured in watts per square meter . A typical solar panel is around 14-15 W m 2. This means that one solar panel can produce about 1,400 watts of power. To determine the number of panels you need, you first need to figure out how many square meters your home is.

The Use Of Solar Energy
Solar energy is one of the most promising renewable energy sources. It is abundant, widely distributed, and clean. Solar photovoltaic technology converts sunlight into electricity, and has been used for over 50 years. There are two main types of solar PV panels: monocrystalline and polycrystalline. Monocrystalline panels are made from a single crystal of silicon, while polycrystalline panels are made from many smaller crystals.
Monocrystalline cells are more efficient than polycrystalline panels, meaning they can convert more sunlight into electricity. They also tend to last longer, with a typical lifespan of 25-30 years. However, they are also more expensive, costing around 20-30% more than polycrystalline panels.
Mono V/s Poly V/s Bifacial
While deciding upon the best type of solar panels for your home, you must be aware of the strength and weaknesses of all the types available. In this section, youll find out the difference between the basic composition and functionalities of the three types of solar panels.
Mono crystal solar panels are made out of highly pure single piece silicon. While on the other hand, poly crystal solar panels are made out of fragments of silicon which were melted together to form the wafer. Bifacial panels can be made of any of these traditional solar cells though they are usually monocrystalline cells.
Comparing the energy efficiency of the three types of solar panels, Monocrystalline panels are over 20% efficient while polycrystalline panels are somewhat less efficient with an energy efficiency lying between 15-17%. Being highly advanced, bifacial solar panels are most efficient with an efficiency rate that can go high to 27%.

Which Panels Should I Choose For My Project
You might be feeling some information overload right now. Its nice to understand the nuances of the manufacturing process, but ultimately theres one question on everyones mind: which one should I buy?
Our advice is always this: look at cost-per-watt and go from there.
To make a fair comparison between products, divide the panel cost by its rated wattage. The result tells you how much power you will generate per dollar you spend. For example:
- Mission Solar 385W solar panel: $319 / 385W = 82 cents/watt
Going with Mission Solar would mean fewer panels in your array, but the overall system will cost more due to the higher cost-per-watt on the panels.
Once you evaluate pricing on a level playing field, then consider whether other factors play a factor in your decision.
Monocrystalline Versus Polycrystalline Efficiency Table
The chart below indicates the maximum efficiency of the average solar panel types arranged from most to least efficient.
As you can see, technological advances have increased the efficiency of the traditional mono and poly panels, with the N-Type mono panels delivering the best efficiency currently.
Before rushing off and buying the biggest and the best solar panels for your home, discuss your needs with your local solar supplier or installer, as some installations will only require a basic solar panel to get the job done well.
| Solar Panel Description |
HJT = Heterojunction technology.
N-Type = Negatively charged cells electrons flow from the base of the cell to the top.
PERC = Modified conventional cell generating up to 12% more energy than the equivalent non-PERC solar panels.

Best Applications For Polycrystalline Solar Panel
- Aesthetics not a priority
Polycrystalline solar panels are best when you need to observe the bottom line.
Because monocrystalline panels tend to cost about $0.05 per watt more, the polycrystalline units are a better value, as long as you have enough space for the panels.
Polycrystalline solar panels work better in areas that are rich in sunlight since they deliver less wattage than the panels.
The bluish tint and speckled appearance of the polycrystalline panels may not suit everyone, especially when installed in large numbers in residential areas. But they do work well for rural areas or for urban areas where the panels can be conveniently tucked away, like on a rooftop or in back of the property.

What Is Mono Solar Panel
Monocrystal silicon cells or mono solar panels are those in which the whole cell area is made up of only one crystal.
Because of the manufacturing method and the structure of single crystalline silicon, a normal mono-crystalline solar panel is dark in color, and the corners of the solar panel are generally curved and rounded up.
When solar panels were initially introduced to the market, monocrystalline solar panels were thought to be superior to poly photovoltaic power. This view is based on several factors.
Mono panels are the most efficient, with effectiveness rates ranging from 15-20%. Because of their amazing accuracy, they create more electricity per sq foot and take up less space.
In hot temperatures, these solar cells are more efficient. As the temperature is raised, performance drops a little, although not as much as with poly solar panels.
Nevertheless, it is clearly not true that mono solar panels are superior to poly solar panels. Without generalization, each solar array and photovoltaic makers should be evaluated separately.
The Czochralski technique or floating area technique are the most common methods for producing mono silicon wafers for the creation of mono and poly solar cells.
