Types Of Solar Panels Faqs
Solar panels are a significant investment, and its important to understand the differences in each panel type to make an informed decision. These are answers to some of the questions we most commonly get:
Which Solar Panel Produces Most Electricity?
Monocrystalline solar panels have the highest efficiency and power rate. From a percentage standpoint, monocrystalline panels can reach efficiencies higher than 20%. In comparison, polycrystalline panels reach efficiency levels of around 15-17%.
Monocrystalline panels also have higher wattage modules, which contributes to the power capacity.
Which Solar Panels Look the Best?
The three types of solar panels are each made differently, so they have different aesthetics.
Monocrystalline panels have a black appearance due to how light interacts with pure silicon. Polycrystalline panels have a blue tone due to light reflecting differently off silicon fragments.
Thin-frame panels have a lower profile and thinner appearance, making them the slimmest of all the solar panel options.
Which Solar Panels Are the Most Cost-Effective?
Monocrystalline panels are the most expensive to purchase due to the manufacturing process. However, they take up less space, are more energy-efficient, and come with a longer warranty than other panels. If you keep your property for a long time, the cost evens out eventually.

The Best Type Of Solar Panels
So are monocrystalline vs. polycrystalline vs. thin film panels better? The best type of solar panels depends on the purpose of the panels andwhere theyll be installed. For residential properties with a large roof space or property, the best choice of panels may be polycrystalline. These panels are the most affordable for large spaces and will provide enough efficiency and power. For residential properties with smaller spaces, monocrystalline solar panels may be the best choice. These panels work well for those who want to maximize their energy bills in a small space. Monocrystalline solar panels and polycrystalline solar panels are good fits for homes and other similar buildings. Thin-film solar panels are almost never used on homes because they are lower in efficiency. Instead, thin-film solar panels are perfect for commercial buildings that cant handle the additional weight of traditional panels. Though thin-film is less efficient, commercial roofs have more space to cover more of the roof with panels.
If youre not sure which of the types of solar panels will work best for your project or you want some guidance on understanding solar panel technology, our experts at8MSolarcan help you determine the right panels for your unique project.
The Future Of Solar Panels
A lot of energy and research is currently going into solar panels at the moment, to make it more efficient and to bring down the cost. Did you know you can now get a solar panel array to power your caravan or tent? The new thin film solar panel technology means that you can have portable systems that can be rolled up when you pack up and return home.
Researchers in the US are looking at clear solar panels that can be incorporated into windows, making installation easier and increasing the aesthetics of the technology. The other major research activity is in developing the photovoltaic cells themselves, and helping to concentrate sunlight to improve efficiency levels.
It could be that the future of solar is bright and its all, literally, in the sunlight. Expect a wider array of more efficient and cheaper solar panels in the years to come.

Solar Cell Count And Efficiency
All PV panels differ in efficiency. Meaning certain types and even brands of Solar panels can convert sunlight into electricity more effectively than others. This is because panels can vary in the number of silicon cells and type they have. The cell count of a Solar Panel often determines its cost, size and weight. Although it is often believed the more silicon cells a panel has, the high wattage and power output it will produce, this isnt always the case. The power output of a panel is dependant on the quality and efficiency of the solar cells themselves.
In this blog we will explore the main three types of solar panel cells: polycrystalline, monocrystalline and thin-film. Understanding the difference between the three, is the very first step to selecting your perfect panel for your home, business or community.

Depending on your energy needs, budget, cosmetic preference and space allotment, its important to weigh the advantages and disadvantages of your three options in solar panels for your home or business.
Two of these solar panel types consist of single-junction solar cells. Theoretically, their maximum efficiency is about 33%. The highest efficiency achieved to date with single-junction cells is about 22%.
The thin-film solar panel may be single- or multi-junction depending on its material. Multi-junction solar cells are made of different materials, each of which best captures photons of varying wavelengths. In this manner, more sunlight can be converted to electric energy.
Thin Film Solar Panels
Meet thin film, the oldest rival to crystalline silicons crown, and irrelevant as of 2017.
What they are: A thin layer of photovoltaic material deposited on a substrate, usually glass. Not just thin, but thin thin. A couple of micrometers thin. Youll mostly find them lounging around in large-scale utility projects, where lack of land isnt an issue. Why? Despite low efficiency, TFs offered the most Watts for your dollar.
Why they were cheaper: TFs use 1/100th of the photovoltaic material of crystalline silicon. Also, manufacturing is a cake-walk. Put glass into the factory on one side, give the factory a few hours to do its magic, and kazam, a thin film panel out the other side. No fuss, no billion dollar arc-furnaces, no crystal-growing funny business.
Why your green alter ego will love them: TFs have a lower energy payback time than mono-Si, and in most cases, multi-Si. CdTe comes in strong: 7 months vs. mono-Sis 20 months and multi-Sis 15 months. CIGS is 12 months, and a-Si is 17.
Why Theyre Irrelevant: China. A Chinese crystalline panel manufacturing boom, combined with government subsidies, have slashed the price of mono and multi-Si, destroying TFs price advantage. TF and multi-Si are very similar in price, but the latter is around 16% efficient, and the former only 7-14%.

Black Solar Panels Versus Blue Solar Panels
Black solar panels are the latest technology. When it comes to solar panel aesthetics, or how they look, many people feel that black panels look better. Even some homeowners associations require black panels. They are sleek and modern and often blend right in with your roof or their surroundings.
Monocrystalline means one crystal. The silicon used for these panels is so pure that it forms one large silicon crystal in the manufacturing process. This also helps give monocrystalline panels their black hue because of the way light is reflected.
Blue solar panels, or polycrystalline solar panels, have been around for a while and are still more widely used than black panels. Their blue color comes from silicon and, often, an anti-reflective coating that boosts efficiency.
The silicon used to make blue solar panels starts as many separate crystals that are placed into a mold in the desired shape. Polycrystalline means many crystals.
Pv: Polycrystalline Solar Panels
Polycrystalline solar panels feature solar cells that contain multiple crystalline fragments of silicon. These panels are made up of perfectly square wafers that are assembled into rows and columns to form a rectangular panel covered with a glass sheet and a metal frame. Unlike monocrystalline solar cells, polycrystalline solar panels tend to have a blue hue.
One of the most significant advantages of choosing polycrystalline solar panels is the lower overall cost. Though they are not as inexpensive as thin-film solar panels, they are the perfect middle-ground option for those looking for crystalline-based solar panels that are aesthetically pleasing and high-performing.
Next to monocrystalline panels, polycrystalline solar panels have a slightly lower heat tolerance, meaning they are not able to perform at their peak amid high temperatures. Although this is an important distinction to keep in mind, especially if you live in a hot climate, the reduced performance shouldnt deter your decision, as the difference is minimal.

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.
The Different Types Of Solar Panels On The Market
The Greek philosopher Heraclitus said Change is the only constant in life. The solar industry is no exception. With the exponential growth of technology and demand for green energy, there are more solar innovations every year.
Despite this, one technology dominates todays market crystalline silicon. With hundreds of billions of dollars invested in their manufacturing, R& D, and infrastructure, the market is brutal for newcomers. A bit better wont cut it. Emerging technologies have to be significantly better in terms of efficiency and cost to warrant a slice of the pie.
But with second-generation thin-film panels floundering, the future now lies in third-generation technologies to break onto the solar scene and change the world energy order as we know it.
Well get to them later. First, lets ogle at the panels taking center-stage on a roof near you:

Where Is Residential Solar Headed
Solar panel development is a rapidly evolving field. New technologies are being developed each year that offer increased solar efficiency, faster and cheaper manufacturing, and better long-term durability.
The newest technology in the solar market is the concentrator photovoltaic panel. Developed by the GW School of Engineering and Science, CPV panels shatter previous barriers to solar efficiency with a whopping 44.5% conversion rate.6 Using crystalline lenses, these panels focus sunlight onto very tiny photovoltaic cells that are stacked on top of each other. As concentrated sunlight passes through multiple photovoltaic cells, several wavelengths of light are captured, resulting in the impressive efficiency rating.
Right now, CPV technology is too expensive to mass-produce for consumers. However, breakthroughs like CPV panels are frequentthe next generation of solar technology might soon be found on the roof of your home.
Types Of Semiconductors And Other Materials
- Organic NA
- Quantum dots NA
So that is an extensive list of semiconductor material but it narrows down with the important ones. Certainly, silicon is used in few different ways to make solar cells. Also, they are efficient and cheap at the same time, due to abundance of silicon. Other compounds like CIGS, CIS, CdTe and CuInS2 are also used to make solar cells and panels but in limited way. Whereas, perovskite, organic and quantum dots technologies are under research with possible potential for the future. Furthermore, let us have a look at the types of solar panels which are available in the market.

For your solar system investment to pay off, you will have to wait for at least six years. Although solar energy will reduce your electricity cost, the installation process is costly, making the entire cost high. If you plan on staying in your house for a long-term period, solar panels are a great option. However, if you plan on moving houses, look for other methods to decrease your energy use.
Power Optimizers: Pros And Cons
Power optimizers are located on the back of each solar panel, and they work in conjunction with a string inverter to convert DC to AC. They do this by conditioning the DC electricity from each panel and sending that conditioned DC to the string inverter to convert to AC electricity.
Pros: Because power optimizers can condition the DC electricity produced by each individual solar panel, they can decrease the impact of shading on individual panels. If one solar panel is partially shaded, it will not degrade the output of the entire string as with a simple string inverter setup.
Power optimizers also have the benefit of allowing panel-level monitoring, along with system-level monitoring thanks to the string inverter. This means any issues with solar output can be diagnosed more easily, with each solar panel being monitored individually. It also allows the homeowner to see a more detailed level of monitoring.
Cons: Power optimizers are more expensive than using just a string inverter, but they are still less expensive than microinverters.
Power optimizer systems also require additional power optimizers and potentially additional string inverters if you expand your solar panel system in the future.
It is also important to note that because power optimizers are located on the roof, it is more difficult to repair and replace them if they would happen to have any issues.
