How do I choose the right solar panel?

How do I choose the right solar panel?, If you are installing a solar system in your house then you will want to choose the best solar panels for your home. But there are so many options available and it can be tough to know which solar panels you need.

As all homes area unit are totally different from one another thus there is no best solar array for each system and it’s necessary for owners to assess their specific must choose the proper solar array to accommodate their home energy wants.

How do I choose the right solar panel?

If you want to take advantage of solar power then the first step is to assemble a solar system for home use and this system will include a battery, an inverter, and an array of solar panels. Here we discuss some of the factors that you should use to identify the perfect solar panel for your house-

  • Efficiency
  • Durability
  • Price Point
  • Warranty
  • Temperature Coefficient

Efficiency- You must check out the efficiency ratings of a solar panel, which refers to the amount of captured sunlight that it can convert into energy. But you should keep in mind that solar panel efficiency tops out just 20% and the most efficient solar panels will yield energy savings for your home requirements.

Durability- Solar panels require a significant investment so you should select solar panels that are going to hold up over time, so this all means that must buy the solar panels that are made to be more durable and also can bear the even intense weather.

Price Point- You must consider your budget before investing in any solar panel. The cost of solar panels can vary based on a number of factors. If you think about the solar panel’s price then it depends on the factors like warranty and durability which give you a complete understanding of the overall value of solar panels.

Warranty- You must understand that a  strong and good performance warranty could give you peace of mind after you buy solar panels for your home. As in the solar panels industry, a decent warranty may be in between from 10 to 25 years.

Temperature Coefficient- Another important factor is temperature coefficient, which refers to how much or how little the solar panel’s productivity is diminished when the external temperature rises, as external heat plays an important role in power output throughout the year.

Which type of solar panel is best for home use?

Which type of solar panel is best for home use?

There is a number of solar panels on the market for residential solar systems. Solar panels come into three categories-

  1. Monocrystalline Solar Panels
  2. Polycrystalline Solar Panels
  3. Thin Film Solar Panels

Each of those styles of solar cells causes the solar panels to possess different characteristics. that the question comes that that is that the best sort of solar panel for home use. So the question comes that which is the best type of solar panel for home use. During this article, we are going to understand the variations between these 3 varieties of star panels so that you’ll be able to decide that one is good for you.

Monocrystalline Solar Panels

Monocrystalline Solar Panels are the most popular solar panels that are used these days for rooftop solar installations because of their look.  You can easily identify a monocrystalline solar panel by the shape of the silicon wafers that are used in it, they are of square-like shape with sharp edges.

Construction- Monocrystalline Solar Panels get their name from the process that they are made, as each of the solar cells have silicon wafer that is made up of a single crystal of silicon. This single silicon crystal is formed by using the Czochralski method. In the Czochralski method a seed crystal is placed into a vat of molten pure silicon at a very high temperature, then the seed is drawn up and the molten silicon forms around it that make one crystal.

The large crystal is also known as an ingot and then it is cut into some thin wafers that are used to create the solar cells. In numerous terms you will like fewer monocrystalline panels in your system to return up with the identical amount of power, to boot makes monocrystalline solar panels for you if you have got restricted space.  A monocrystalline solar panel usually has 60 or 72 solar cells and this is depending on the size of the solar panel. But most of the residential installations use 60 cell monocrystalline solar silicon panels.

Performance- Monocrystalline solar panels efficiencies can lie between 17% to 22% and that they have the best potency and power capability out of all 3 styles of solar panels.  The higher efficiency of this type of solar panel is because that they are made up of a single silicon crystal which makes electrons flow easier through the cell.

Monocrystalline solar panels require less space to reach a given power capacity. In different terms you may need fewer monocrystalline panels in your system to come up with an identical quantity of power, this additionally makes monocrystalline solar panels for you if you have a limited area.

Cost- The procedure that is used to manufacture monocrystalline solar panels makes them more expensive than other kinds of solar panels. And the high efficiency and power ratings of monocrystalline solar panels also rise the price. But as solar technology and manufacturing have improved the price difference between monocrystalline and polycrystalline solar panels narrows down.

Polycrystalline Solar Panels

Polycrystalline Solar Panels are also known as multi-crystalline solar panels are famous among homeowners to install on a budget. Polycrystalline solar panels do have not the corners cut off them so you would not see the large white space on the front of the solar panel that you can see on the monocrystalline solar panel.

The process they are manufactured by causes the panels to have blur color which you can consider to be an eyesore and the process also makes them less efficient than monocrystalline panels.

Construction- Polycrystalline solar cells are manufactured the same as monocrystalline panels a seed crystal is placed into molten silica. In place of pulling out the silicon in the seed crystal, the whole vat of semiconductor material cools and this cooling method causes a number of crystals to do try to be made.

These multiple crystals square measure what causes the panels to own blue color. Same as monocrystalline solar panels, polycrystalline solar panels have 60 or 70  cells.

Performance- The multiple silicon crystals in each solar cell make it tough for electrons to flow. This crystal structure makes the efficiency rate of polycrystalline solar panels lower than monocrystalline solar panels. The efficiency ratings of polycrystalline solar panels lie between 15% to 17%.

But thanks to new technologies that polycrystalline solar panels are now much closer in efficiency to monocrystalline panels. Quality standards are improving in polycrystalline solar panels which also helped to increase the standards 60 cell polycrystalline solar panels from 240 watts to 300 watts.

Cost- Polycrystalline solar panels are low in cost to produce as compare to monocrystalline solar panels and this allows them to make up a considerable market share in home installations. But the lower performance of polycrystalline solar panels has caused more people to choose monocrystalline solar panels.

Thin Film Solar Panels

Thin-film solar panels are that the form of solar panels that’s fully completely different from each monocrystalline and crystalline solar panel. Thin -films solar panels are in solid black color while not the traditional semiconducting material cell define that you just will see on the face of the crystalline solar panels.

Thin-film solar panels are more flexible and lightweight which them easier to install as compare to monocrystalline and polycrystalline solar panels. This type of solar panel is mostly used in large-scale operations like utility or industrial solar installations because of their low efficiency.

Construction- Thin film solar panels are manufactured by a method in which a thin layer of photovoltaic substance is depositing onto a solid and smooth surface such as glass. Some examples of photovoltaic substances – Amorphous silicon, Cadmium telluride, Dye- sensitized solar cells and Copper indium gallium selenide. Each of these photovoltaic substance can make a different type of solar panel however they all come under thin -film solar cells.

The manufacturing process that is used to manufacture thin- film solar panels ends up being lightweight and flexible. But this manufacturing method makes them less efficient than both monocrystalline and polycrystalline solar panels. Sanyo, First Solar and Kanaks are some of the most famous manufacturers of thin- film solar panels.

Performance- Thin -film solar panel technology is considered as one of the worst solar panels technologies because they have poor efficiency. Thin films solar panels that are available for commercial use generally have efficiency ranges between 10% t0 13%. The low efficiency means you need to install more thin-film solar panels to generate an equal amount of electricity as a monocrystalline or polycrystalline solar panel.

Thin-film solar panels do not make sense for home installations because of their low efficiency and where space is limited. But they work more efficiently in large-scale installations such as industrial and utility solar projects because more panels can be installed to fulfill the energy demands.

Cost- Thin-film solar panels have the lower cost out of all three types of solar panels because of their low performance. But they are easy to install as compare to crystalline silicon panels which lower their price. The simple and easy installation process is the main reason that why thin-film solar panels are great for large-scale commercial projects.

Although the cost of monocrystalline and polycrystalline solar panels continues to get lower, which means that a more powerful and efficient monocrystalline and polycrystalline solar system would not cost you more than a larger and less efficient thin-film solar system.

Do Solar Panels Really Pay Off (Briefly Explained)

The best solar panel for your home

The best solar panel for your home

Thin- film solar panels do not make sense for home use solar installations. However, they are cheaper, they will want more room and wouldn’t generate the maximum amount of electricity as monocrystalline and crystalline solar panels.

It makes sense to install monocrystalline solar panels for residential solar panel installations. But you have got to pay a high price, high efficiency and a more good looking than you would with crystalline solar panels. However, if you are on a tight budget then polycrystalline solar panels might build more sense for home solar system installation.

In my humble opinion, the choice between polycrystalline and monocrystalline solar panels is not the most important choice you make when you are purchasing solar panels for residential use. These are the two important things to consider than solar cell type once shopping for solar panels for residential use.
