This is what we’re trying to avoid, so read on!

Different Sizes of Solar Photovoltaic Panels

Three main PV solar panel types are monocrystalline, polycrystalline, and thin or flexible film.

Find the answer to the question, how big are solar panels?

Monocrystalline Solar Panels

A monocrystalline solar panel is made from single-crystal silicon and is the most reliable type of solar panel.

They have a uniform black colour and rounded edges — popularly used residential solar panels.

A monocrystalline residential solar panel typically comes in two sizes: 60-cell and 72-cell.

The 60-cell panels are about 65 by 39 inches and have a power output of around 280-320 watts, and the 72-cell panels are about 77 by 39 inches and have more power output of around 340-400 watts.

One of the heaviest was Canadian Solar, which weighs as much as 50 pounds.

Polycrystalline Solar Panels

These solar panels are made from melted multiple small silicon crystals and have a distinctive blue colour.

They are slightly less competent than monocrystalline PV cells but are also less expensive.

Polycrystalline panels come in different sizes, from small-weight panel options for portable use to large-weight commercial solar panels.

Typical sizes for commercial installations include the following: 

• 60-cell panels: 65 by 39 inches, with an electrical output of around 280-320 watts)
• 72-cell panels: 77 by 39 inches, with an electrical output of around 340-400 watts)

Polycrystalline is also a good source for residential solar panels.

Thin-Film Solar Panels

These solar cells are made by depositing a thin layer of photovoltaic material onto a substrate such as glass, plastic, or metal.

They are less efficient than crystalline cells but are sleek weight, flexible, and can be made in various sizes and shapes.

TF solar panels come in two main types: amorphous silicon and cadmium telluride.

• Amorphous silicon solar cells are typically used for small solar panels such as portable solar chargers and come in square foot sizes.
• Cadmium telluride solar cells are used for larger-scale applications such as utility-scale solar farms and can be as large as several feet wide and up to 10 feet long.

Factors to Consider When Choosing Solar Photovoltaic Panel Size

Apart from knowing how to install a solar panel, there are several factors to consider when choosing a solar panel size.

Roof Space

The available space will determine the system size and how many solar panels can be installed on your roof.

You must install the solar panels you need where it receives maximum sunlight since the energy they generate is directly proportional to the amount of sunlight they receive.

Solar cells should be installed at an optimal angle and direction to receive the most sunlight to maximise energy production.

How many panels you need will depend on the available roof space, as larger solar cells require more roof area.

Solar System Capacity

If the capacity is too low, the solar system will not generate enough electric energy to meet the property’s energy demands; If the capacity is too high, it will generate more energy than needed, resulting in wastage.

The capacity of a solar system is measured in kilowatt-hours (kWh) and is determined by the total power rating of all the solar panels installed.

The solar system’s capacity should match your property’s energy consumption and be in conjunction with the available area on your roof.

Budget

Choosing the right size panels will help you stay within your budget and maximise your investment.

In addition to the cost of photovoltaic solar panels, other factors that can affect the overall expenses of a solar system include installation fees, equipment, and maintenance expenses.

Many states and local governments offer tax credits or rebates to incentivise the installation of solar systems. Federal tax credits are also available for solar installations.

Checking different manufacturers (like Canadian Solar and Hanwha Q cells) helps.

Continue reading to discover which standard solar panel size is better.

Monocrystalline Panels

Monocrystalline solar cells have several benefits, making them popular among homeowners and businesses.

While they are the most effective solar cell on the market, several advantages and disadvantages also come with monocrystalline solar panels.

Pros

Here are some of the benefits of monocrystalline panels:

• Higher electrical output, efficiency at 15-20% – are made from a higher grade of silicon, which is more efficient at converting sunlight into more electricity per square foot.
• Most durable – due to higher-quality materials and construction, they can maintain their performance over a longer period. Plus, warranties range from 25 to 30 years.
• Less space – because they produce higher solar power, they can generate solar energy without extra roof area.

Cons

Here are some of the drawbacks of monocrystalline panels:

• Higher cost – these solar cells are more expensive than others because of their high efficiency and durability.
• Low performance in low-light conditions – designed to work best in direct sunlight.
• Carbon footprint – producing these solar cells still requires a certain amount of energy and resources, including high-grade silicon, which can have environmental impacts.

Polycrystalline Panels

The polycrystalline panel is also the standard size for residential and commercial panels.

These solar cells are made from multiple silicon crystals, which are melted to form a solar array.

Pros

Here are some of the benefits of a polycrystalline solar panel:

• Lower cost – These commercial solar panels are known for being more affordable than their monocrystalline counterparts.
• Good performance in high temperatures – they are less affected by heat.
• Durable – these can last for many years of use.

Cons

Here are some of the drawbacks of a polycrystalline solar panel:

• Lower efficiency, 13% to 16% efficiency – they require more area to generate the same amount of electrical output as a monocrystalline solar panel.
• Uses a larger rooftop area – because they use less pure silicon, you will need more solar panels.
• Less uniform appearance – this solar panel tends to be larger and bulkier than other panels, making it more difficult to install seamlessly into a building’s design.

Thin-Film Panels

This solar panel is a photovoltaic (PV) panel that offers several advantages over the standard solar panel size, making them a good alternative.

Pros

What Is the Typical Size/Dimensions of a Solar Panel?

The standard solar panel dimensions can vary depending on the type and manufacturer.

The physical dimensions of most standard commercial panels are usually around 77 by 39 inches, with a thickness of around 1.5 inches.

Most residential solar panel dimensions are standardised to around 60 cells and are roughly 65 by 39 inches in size dimensions, with a thickness of around 1.5 inches.

How Much Do Solar Panels Weigh?

The average solar panel weight can vary according to the solar panel dimensions and type.

Standard residential solar panels weigh between 40 to 50 pounds (18 to 23 kg).

How big are solar panels means that a typical solar panel system for a home has several hundred pounds weight, depending on the number of solar panels installed.

Considering how much solar cells weigh when planning for home or commercial panels installation is important.

Can Your Roof Support a Solar Panel System?

Most roofs can support the weight of most solar panels — a slanted roof is the greatest option for a solar panel, but flat roofs are fine.

However, check with professional solar installers to understand how solar photovoltaics work.

It’s important to assess your roof before installing solar panels to ensure it’s in good condition and has the structural integrity to support the weight of the solar panels.

Whether or not your roof can support a solar panel system depends on several factors, such as the age and condition of your roof, the different materials used, and the dimensions and weight of the solar panels.

Are There Multiple Sizes of Solar Panels?

Yes, many solar panel sizes are available on the market, and they can vary depending on the types of solar panels and the manufacturers.

Most residential solar panels’ standard size range from 65 by 39 inches, or 17.3 square feet, to 78 inches by 39 inches, or 20.5 square feet.

Average solar panel size — large or small solar system size — is available to produce different levels of energy output.

Conclusion

Regardless of how big solar panels are, they comprise a series of single solar cells, all connected in parallel circuits to form the entire solar system.

Of course, how many solar panels you’ll need depends on how high your energy consumption is.

Also, the more wattage a solar panel produces, the more solar panel square foot you’ll need.

Out of the three types of solar panels, monocrystalline are the most efficient, polycrystalline are the cheapest, and thin-film panels are the most portable.

The type of solar panel you need depends on the type of system you want to install. For a traditional rooftop solar panel system, you'll usually want monocrystalline panels due to their high efficiency. If you have a big roof with a lot of space, you might choose polycrystalline panels to save money upfront. Want to DIY a portable solar setup on an RV or boat? Thin-film solar panels are a great option. 

Over the last 130 years, solar panel technology has evolved in the pursuit of higher efficiency, lower costs, aesthetics, and durability. While each of the three modern designs comes with advantages, the current solar panel market tends to align panel technology with the most cost-effective and savings-driven application.

There are three major types of solar panels: monocrystalline, polycrystalline, and thin-film. The solar panel type best suited for your installation will depend on your preferences and factors specific to your own property.

Monocrystalline panels are usually the most expensive solar panel type. Manufacturers must absorb the costs of making solar cells from a single crystal. This process, known as the Czochralski process, is energy-intensive and results in wasted silicon. But don't worry–this silicon can later be used to manufacture polycrystalline solar cells.

Polycrystalline solar panels are typically cheaper than monocrystalline panels. The cells come from silicon fragments rather than a single, pure silicon crystal. This allows for a much simpler cell manufacturing process, costing less for manufacturers and homeowners who install the panels.

What you pay for thin-film solar cells largely depends on the type of thin-film panel. CdTe is generally the cheapest type of solar panel to manufacture. CIGS solar panels are much more expensive to produce than CdTe or amorphous silicon.

The overall cost of a thin-film solar panel installation is usually lower than a monocrystalline or polycrystalline solar installation. Thin-film solar panel installations are less labor-intensive because the panels are lighter and more maneuverable. It's easier for installers to carry them onto rooftops and secure them. Installers generally charge less for labor with thin-film panels, making the installation less expensive overall.

Each type of solar panel varies in how much power it can produce. If you have limited roof space, choose a high-efficiency solar panel to get the most out of your system.

Monocrystalline panels typically have the highest efficiency and power capacity. They can reach efficiencies of over 22% and provide over 300 watts (W) of power capacity. Many even exceed 400 W. Polycrystalline solar panels, on the other hand, rarely exceed 17% efficiency and tend to have lower wattages.

Monocrystalline solar panels also tend to perform better than polycrystalline panels in warm temperatures. They usually have lower temperature coefficients, which means they maintain higher efficiencies when it's hot outside.

While they differ in performance, monocrystalline and polycrystalline panels are about the same size physically. Both types of solar panels tend to come in 60, 72, and 96 silicon cell options.

Thin-film solar panels have lower efficiencies and power capacities than monocrystalline or polycrystalline panels. Efficiencies vary based on the specific material used in the cells, but thin-film solar panels tend to be around 11% efficiency.

Thin-film solar cell technology does not come in uniform sizes. The power capacity from one thin-film panel to another largely depends on its physical size. Generally, the power capacity per square foot of monocrystalline or polycrystalline solar panels will exceed that of thin-film panels.

Solar cells include a semiconducting material that converts sunlight into electricity by turning photons into electrons. Silicon is the most common material used as a semiconductor during the solar cell manufacturing process.

Both monocrystalline and polycrystalline solar panels include silicon wafer cells. To build a crystalline panel, manufacturers assemble wafer cells into rows and columns to form a rectangle. They then cover the cells with a glass sheet and frame the glass.

Monocrystalline and polycrystalline panels vary in the composition of the silicon. Monocrystalline solar cells are cut from a single crystal of silicon. When manufacturers create polycrystalline solar cells, they melt fragments of silicon crystals together in a mold.

Unlike monocrystalline and polycrystalline solar panels, thin-film panels can be made from multiple materials. The most prevalent type of thin-film solar panel is made from cadmium telluride (CdTe). To make this type of thin-film panel, manufacturers place a layer of CdTe between transparent conducting layers that help capture sunlight. This type of thin-film technology has a glass layer on the top for protection.

Thin-film solar panels can also use amorphous silicon (a-Si), similar to the composition of monocrystalline and polycrystalline panels. Though these thin-film panels use silicon layers in their composition, they are not made up of solid silicon wafers. Instead, they're composed of non-crystalline silicon placed on top of glass, plastic, or metal.

Copper Indium Gallium Selenide (CIGS) panels are another popular type of thin-film technology. In CIGS panels, the semiconductor material made of copper, indium, gallium, and selenide, attaches to a conductive substrate made of glass, nylon, aluminum, or steel. Manufacturers place electrodes on the panels' front and back to capture electrical currents.

Want solar panels that don't stand out too much against your roof? Pay close attention here. Variations in materials and production cause differences in appearance between each type of solar panel. Some look better than others on a traditional black shingle roof.

While the solar cells are black, monocrystalline solar panels have a variety of colors for their back sheets and frames. The back sheet of the solar panel will most often be black, silver, or white, while the metal frames are typically black or silver.

Thin-film solar cells are roughly 350 times thinner than the crystalline wafers used in monocrystalline and polycrystalline solar panels. However, an entire thin-film panel may be similar in thickness to a monocrystalline or polycrystalline solar panel if it includes a thick frame. There are adhesive thin-film solar panels that lie close to the surface of a roof. But more durable thin-film panels have frames up to 50 millimeters thick.

Monocrystalline, polycrystalline, and thin-film panels each have advantages and disadvantages, and the solution you should move forward with depends on your property and your savings goals.

If you have a lot of space for solar panels, you can save money upfront by installing lower-efficiency, lower-cost polycrystalline panels. If you have limited space and want to maximize your electric bill savings over 20 years, we recommend high-efficiency, monocrystalline solar panels.

As far as thin-film panels go, it's most common to choose this type of solar panel if you're installing a portable or DIY solar system, like on an RV or boat. Businesses also use thin-film panels for large, commercial roofs that can't handle the additional weight of traditional solar equipment. These roofs can also afford the lower efficiencies of thin-film panels because they have more roof space.
