With increasing pollution and the world focusing on sustainability, solar is the way to go. When people go into the market to find the best solar panel, they often seem clueless because, obviously, not many people know about it. Well, we have got you covered. In this article, we will give you a detailed overview of the solar panels that are best for your home.
There are three types of solar panels: monocrystalline solar panels, polycrystalline solar panels, and thin-film solar panels. In this blog, we will help you decide what kind of solar panel is best for your home.

Monocrystalline solar panels:

These are the most common types of solar panels for residential systems because they’re the most efficient and better suited for roofs with limited space. Monocrystalline panels are usually the most expensive type of solar panel. Monocrystalline solar panels, or mono panels, are made from a single silicon crystal. Monocrystalline solar panels have black-colored solar cells made of a single silicon crystal and usually have a higher efficiency rating.
A monocrystalline solar panel is made from monocrystalline solar cells that are also known as “wafers”.  Although these solar panels are generally considered a premium solar product, the primary advantages of monocrystalline panels are higher efficiencies and aesthetics, as they look visually more appealing. Because a monocrystalline cell is composed of a single crystal, the electrons that generate a flow of electricity have more space to move. As a result, monocrystalline solar cells are more efficient as compared to their polycrystalline counterparts. You will need fewer monocrystalline panels for your roof to produce more kWh of electricity than others because they generate more electricity, but they’re more expensive per panel.
Because a monocrystalline cell is composed of a single crystal, the electrons that generate a flow of electricity have more room to move. These high-quality solar panels are designed to face harsh weather conditions, including rain, snow, and hail. They typically come with warranties ranging from 20 to 25 years. With proper care and maintenance, their shelf life can be increased as well.

Polycrystalline solar panels:

Polycrystalline Solar Panel

Polycrystalline solar panels have blue-colored cells made of multiple silicon crystals melted together. Polycrystalline solar cells are also called “multi-crystalline” or many-crystal silicon. Polycrystalline solar panels are also made from silicon. However, instead of using a single silicon crystal, manufacturers melt many silicon fragments together to form wafers for the panel. Polycrystalline solar cells are also called “multi-crystalline” or many-crystal silicon.
Polycrystalline solar panels are made using modern technology, due to which they are more affordable as compared to monocrystalline solar panels. Generally, Polycrystalline solar panels have lower efficiencies as compared to monocrystalline solar power options because there are many more crystals in each cell, meaning less freedom for the electrons to move. These panels have an easier manufacturing process as compared to monocrystalline solar panels, so they have a lower price point on average. In addition, polycrystalline solar panels tend to have a blue hue instead of the black hue of monocrystalline solar panels. Because they are less efficient than other panels, you will need more to provide electricity for your home, but their individual cost is lower.

Thin-film solar panels:

Thin-film solar cells are less efficient than monocrystalline and polycrystalline solar varieties. As a result, they are more often used in large industrial solar installations where space is not something to be worried about. Thin-film panels can also be a good option for small solar projects, such as powering a boat, and small commercial buildings with thin metal roofs, such as a warehouse.
What you pay for thin-film solar cells largely depends on the type of thin-film panel. Even thin-film solar panels have two types, which are CdTe and CIGS. CdTe is generally the cheapest type of solar panel to manufacture. CIGS solar panels are much more expensive to produce than CdTe.
The overall cost of a thin-film solar panel installation is usually lower than that of a monocrystalline or polycrystalline solar installation. Thin-film solar panel installations are less labor-intensive because the panels are lighter and more sensitive. 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.

Conclusion:

This blog has provided information about various types of solar panels, highlighting their advantages and disadvantages. Now, it’s up to you to consider what kind of solar panel is best for your home. Essentially, it’s important that choosing the best type of solar panel for your home involves weighing the pros and cons of each option, considering factors such as efficiency, cost, durability, aesthetics, and more that have been provided within this blog. Ultimately, the decision is yours, and you’ll need to balance your priorities and financial considerations to find the most suitable solar panel solution.

Solar panels are devices that convert sunlight into electricity. They are made up of multiple solar cells that are typically made of silicon and generate direct current (DC) electricity when exposed to sunlight.

According to modern research based on average electricity consumption and peak sun hours it takes around Seventeen 400-watt solar panel plates to power a house. However, this number will vary between 13-19 based on how much sun the panels get and how much electricity the home uses.

The amount of solar panels that a house needs to be powered is based on a lot of factors. Factors include Energy Usage, Orientation and Tilt, Roof Space, Panel Efficiency, and Budget.

Here is a detailed overview of the key points that are mentioned above if you are looking for what size solar panel you need to power your house.

Energy usage:

The first thing that you need to consider is your monthly energy consumption. You can find your monthly energy consumption from your electricity bill. It shows all the energy your house is consuming over the month.

Another way to find out your energy usage is with the help of a Kwh calculator. This kWh calculator makes estimating your home’s electricity usage easy. Whether you live in a small unit or a large house.

The calculator will provide an approximate monthly kWh usage amount. This estimate accounts for factors like home size, number of people, and consumption behaviors. This is how it works all you need to do is enter some minor house details like home square footage, number of occupants, and your energy habits (low, average, high usage).

If your home is over 2,000 square feet, your electricity use may be higher. As a general reference, here are estimated monthly kWh usage ranges based on home size:

  • 2,500 sq ft – 1,250 to 2,500 kWh
  • 3,000 sq ft – 1,500 to 3,000 kWh
  • 3,500 sq ft – 1,750 to 3,500 kWh
  • 4,000 sq ft – 2,000 to 4,000 kWh
  • 4,500 sq ft – 2,250 to 4,500 kWh
  • 5,000 sq ft – 2,500 to 5,000 kWh

You need to remember that your actual usage depends on many factors like weather, number of occupants, appliances, and more.

Roof Space:

The available roof space for solar panel installation is also a key factor that impacts the size of the solar system you can install. You need to consider the size and shape of your roof. You need to see if your roof is big enough to accommodate the number of solar panels you’ll need also you need to see if there are any obstacles (trees, chimneys, etc.) that could block the sunlight from reaching the panels. The angle of your roof and the direction of your house also play a vital role in the efficient working of your solar panel.

You will use a solar roof calculator and the calculator will tell you how many 100-watt, 300-watt, or 400-watt solar panels you can put on your roof. When you have calculated how many of either 100-watt, 300-watt, or 400-watt solar panels you can put on roofs ranging from very little 300 sq ft roofs to huge 5,000 sq ft roofs, summarize the results in a neat chart.

Panel Efficiency:

Solar panel efficiency is a very important factor to consider when evaluating the performance of a solar energy system. This panel efficiency refers to the ability of a solar panel to convert sunlight into usable electricity. Calculating solar panel efficiency involves comparing the amount of sunlight that hits the panel to the amount of electricity it produces. By determining the efficiency, you can evaluate the effectiveness of your solar panels and make informed decisions about their installation and usage.

Solar panel efficiency refers to the percentage of sunlight that a solar panel can convert into usable electricity. Higher numbers mean more electricity is generated from the same amount of sunlight. Several factors can influence performance, including solar cell material, temperature, angle and orientation, and dust and debris. Good photovoltaic panels are crucial for the overall performance of a solar power system, leading to cost savings and a reduced environmental footprint. Know the module’s power capacity. It should be generating electricity based on its capacity if not then the solar panel will not work efficiently.

A very important way of knowing solar panel efficiency is the Solar panel efficiency formula. Here the formula will show how to calculate solar panel efficiency

Solar Panel Efficiency = [ Solar Panel Max. Output P(max) ÷ (Solar Panel Area In m² × 1000) ] × 100

Orientation and Tilt:

Solar panel orientation refers to the direction solar panels face. It is a crucial factor in their efficiency. Selecting the right orientation for your solar panels revolves around cardinal points. In the northern hemisphere, south-facing panels are usually the best choice, while in the southern hemisphere, north-facing panels are ideal. However, east and west-facing orientations can be suitable if you have specific energy production requirements. The tilt and angle of solar panels are key factors in influencing how much sunlight they receive.

Throughout the day and the year, the sun’s angle and direction fluctuate. To guarantee that the panels receive the most sunlight possible it is important to tilt them and align them in the best possible ways. An improper tilt or orientation can lower energy output substantially and raise energy expenses.
