What Is A 100 Watt Solar Panel And Who Is This For

100-watt-solar-panel-kit

Just like the other typical solar panels, a 100Watt Solar Panel is a reliable device to receive sunlight and generate it to electricity or heat.

It uses photovoltaic solar cells that are arranged in rows and columns and sealed with a glass. These efficiently collects sunlight, convert it to power that can be readily utilized by home appliances or simply be stored in batteries for back-ups.

However, it has an average capacity in producing clean and free power. Most probably, because it has a smaller size than the other usual solar panels used in residential and commercial establishments.

Since the wattage capability of the a 100watt Solar Panel is lower than the other panels, such as of those with 250W to 300W capacity, it is more appropriate for those people who has or intends to use small off-grid solar system.

The 100-Watt Solar Panel like the other panels is also for those people who care for our environment. It produces 100% Eco-friendly energy because it emits no greenhouse gases, which are known to be hazardous to the ozone layer.

It is also more suitable for that wanderlust that is looking for portable power supply for their boats, RVs and caravan. It is a very efficient device to charge appliances without compromising the space inside the car.

How Does It Work

As earlier mentioned, the main function of 100watt Solar Panel is to get energy from the sunlight and process it to electricity. Thereafter, said power is stored in a battery so any machines can use it as the need arises.

How it works is really interesting to know. A 100watt Solar Panel makes it possible to convert sun rays to heat through a number of small photovoltaic cells. These are usually composed of 6 to 10 solar cells that are framed together and covered through a smooth glass.

Based on Science, photovoltaic cells looks like a sandwich of two semiconductors. As for solar panels, the common type of material used as semiconductor is the wafer-based silicon.

Said photovoltaic cells works when opposite charges known as the positive and negative electrical charges create magnetic field.

Other parts of the solar panel that are significant in its operations are metal frames, back sheet, brackets, reflectors and wires.

As the solar panels exposed under the scorching sun, it starts receiving sun lights. The efficiency rate of solar panel is determined through a maximum power point. Many light particles called photons slowly move onto the front surface of the panel. It repeatedly occurs until photons reach and knock electrons. This way electricity is form.

As the solar panels harvest pure current, a converter plays a vital role in converting the collected sunlight to electricity. This converter usually lies in the circuit near the solar panels.

Electricity flows and can be instantly use by a solar system and other gadgets or can also be directed to installed batteries which serve as storage.

What Are The Different Types Of 100 Watt Solar Panels

100-watt-monocrystalline-solar-panel

Solar Panels come in different varieties. Though they serve the same purpose that is to receive solar energy, they differ in characteristics, cost, and manner of installations, efficiency rate and forms. Each type of solar panels also has their own edges and shortcomings. Here are the most prevalent types of solar panels.

Monocrystalline Solar Panels

This is the traditional type of solar panel, which was widely used in USA for household and commercial solar system ages ago.

Basically, most solar panels are made of silicon. This material is known for being a highly semiconductor that effortlessly transform light to electricity. But you can easily identify a Monocrystalline Solar Panel by the way the silicon is arranged to its surface.

The silicon cells of a Monocrystalline Solar Panel are individually cut into pure pieces of crystals through a process called Czochralski. This is also the very reason why this type of solar panel tends to have the most expensive price tag among other kinds of panels.

Each wafers of crystal silicon are set-up onto the panel by rectangular rows and columns. All of it looks framed together and the outer finish is protected by a glass sheet.

When you look on its appearance, you can also notice that the Monocrystalline Solar Panel has a more aesthetic value. This type may come in silver or white shade. However, it is usually charcoal black due to the reflection of light to the silicon.

In terms of efficiency rate, the Monocrystalline Solar Panel win the race as it can deliver a whopping 20 percent performance. Probably, it is due to its higher wattage modules that can reach 300 watts power capacity.

Polycrystalline Solar Panels

Nowadays, more people shift to Polycrystalline Solar Panels, most probably because its costs cheaper than the Monocrystalline are.

The silicon use to manufacture the Polycrystalline Solar Panels is usually from the excess fragments initially used for Monocrystalline.

You can also easily determine this kind of solar panel through its bluish color. But other Polycrystalline Solar Panels also comes in silver and white back sheets and frames.

Moreover, it has average efficiency ratings of 15 to 17 percent due to lesser silicon purity applied.

Thin-Film or Amorphous Solar Panels

Among all mentioned types of solar panels, the Thin-Film or Amorphous Solar Panel is the most light weighted, portable and inexpensive.

However, it is also registered as the one with the lowest efficiency of 7 to 10% power capacity only.

Unlike the other kinds of solar panels, it is made of different materials such as of cadmium telluride, amorphous silicon, Copper Indium Gallium Selenide.

The remarkable formation of Thin-Film Solar Panel is it looks slimmer than the other panels. They also use less technology, which makes them easier to manufacture. Hence, they tend to have shorter life span also.

Preference for the type of Solar Panels basically depends on the efficiency and way of installation that you are considering. One is surely more appropriate than the other.

Advantages And Disadvantages Of 100 Watt Solar Panels

The 100Watt solar panels are patronized by clients for their positive benefits. But they also have weak points. Below are the advantages and disadvantages of this type of solar panels.

Advantages

Eco-friendly

Similar to other solar panels, the 100Watt solar panels are patronized because of their capability to harvest renewable energy from the sunlight. Solar energy is known to be purely safe for humans and earth. No toxins or pollution is emitted from the solar panels; hence, it is 100% environment friendly.

Cost Saving

In connection to being Eco-friendly, 100Watt solar panels receive sun rays and convert it to electricity. The electricity that is produced is totally free and clean. It can operate a small solar system, appliances and lights without breaking your savings or increasing your electricity bill.

Portable and Flexible

Most of the 100Watt solar panels have smaller size; hence, they are handy and transferable from one place to another. Although the size of solar panels highly depends on the form, design and efficiency rate, premium types of 100Watt solar panel usually has a measurement of 47x21x1.4 inches.

Due to its mini size, it becomes a portable equipment to charge the appliances and gadgets at homes or even on RVs and boats.

The 100Watt solar panels can also be bended up to 30 degree so they are suitable for locations with curve shapes. They can also be adjusted to directions where they can get enough sunlight.

Easy to install

Another good feature of 100Watt solar panels is that installing them is stress-free and no professional help is needed especially if you have slight knowledge to electronics or wiring. Solar panels usually have incorporated mounting brackets, drilling holes and wire to secure them on your chosen areas.

Disadvantages

Highly Dependent on Weather Conditions

Since the 100Watt solar panels gain its energy solely from the sun, they must be place on a sunny area where they can receive rich sunlight. The problem arrives during inclement weather when the sun is timid. The tendency is that the solar panels fail to absorb sunlight, which affects their performance.

Limited power supply

Although, 100-watt solar panels are good source of back-up energy, you can only expect limited electricity supply. This is because it has a lower power converting capacity compare to the other solar panels with higher wattage such as of the 200 to 350 watts solar panels. It is also the very reason why 100Watt solar panels are only suitable for small solar system and for charging of small home appliances.

High cost of other accessories to set-up the100Watt solar panels

Installation of 100Watt solar panels requires other materials such as battery storage for best performance. Cells and generators usually cost expensive that may add to your expenditures.

Periodic Maintenance

Having the 100-Watt solar panels installed on your roof or on your RVs require minimal maintenance but still an effort to keep them working on best performance. Once in a while, you have to clean the solar panels and remove the blockage from sunlight.

How We Picked And Tested

100-watt-12-volt-solar-panel

A 100-watt solar panel is perfect for those who have smaller loads and/or beginners in solar power. As such, this is quite a popular solar panel.

However, there are a lot of varieties and types in the market that makes it quite difficult and overwhelming to choose one.

This article will enumerate several factors to consider when deciding what solar panel to purchase. This way, you can get a product that can definitely suit your needs.

Power Tolerance

The power tolerance, which provides the realistic amount of power your solar panel, can give. Ideally, a 100-watt solar panel can produce 100 watts of power under perfect conditions. However, there are some factors that can hinder your solar panel from actually producing that power amount, hence, the power tolerance indicator.

The solar panel’s power tolerance is expressed in a plus/minus percentage. When choosing a solar panel, it is important to look at a short percentage range since it means the power output is more stable and certain.

Solar Cell Type

Solar panels come in different types such as monocrystalline, polycrystalline and thin-film types. This section will explain them one by one.

Monocrystalline

Monocrystalline solar panels are made out of high-purity silicon and are dark-colored and shaped like a cylinder.

Among the different types, the monocrystalline solar panels perform better since they have the highest efficiency rates. Their rates range from 15% to 20%. Unlike the other types, they also give a better performance in dim conditions.

Monocrystalline solar panels are also the most durable, having a warranty of at least 25 years. Due to its power, you don’t need to purchase a lot to reach your power load.

However, because of this, they are also the most expensive compared to the others. Their performance also tends to suffer in extremely warm temperatures.

Polycrystalline

Polycrystalline solar panels have a blue color and are square-shaped.

Compared to monocrystalline, these solar panels are cheaper and simpler to use. They are also pleasing to look at due to their uniform color and shape.

However, they have a lower efficiency rate, ranging from 13% to 16%, compared to monocrystalline solar panels.

Thin-film

Thin-film solar panels are the least efficient among the different types of solar panels. They are colored black and are cut in square shapes.

They have an efficiency rate ranging from 7% to 13%, making them the cheapest out of the three. They are also easier to manufacture and are flexible in the sense you can use them for numerous purposes.

Unlike the other two types, thin-film solar panels are further categorized into gallium selenide, cadmium telluride, copper indium, amorphous silicon and organic photovoltaic cells.

However, the thin film solar panels tend to deteriorate faster. Due to the low efficiency rate, you also need to purchase more of them.

Durability

When choosing a solar panel, you should look how much is its wind and snow loads. A higher number means a higher tolerance to these factors.

Moreover, you should also look if it has a certification from the International Electrotechnical Commission to guarantee that it was rigidly tested.

Temperature coefficient

High temperatures usually degrade the performance of your solar panel; hence, it’s important to look at the temperate coefficient. This indicates how the solar panel’s power lowers at high temperatures. Usually 77 degrees Fahrenheit is the threshold since it’s the standard temperature.

Look for panels with lower and less sensitive coefficients since they perform better.

Warranty

A good solar panel is one that is equipped with both power production and materials warranties. Warranties signify that a company cares about its customers and are confident in their product.

A power production warranty indicates how long your solar panel can produce the same amount in years. Typically, a higher number is preferred.

A materials warranty is a stamp of guarantee that shows how long the solar panel will work. Usually, this warranty ranges from 10-12 years.

Of course, these are the not only factors you can look at, as there are a lot. However, these are the most important.

You can also do your own research by comparing different products online or asking friends about their own solar panels.

You can also visit your local stores to see the products for yourself. A salesperson will be more than happy to assist you.
