Making the decision to switch to solar energy is a straightforward process. By opting for this sustainable system, homeowners can reduce their carbon footprint and reliance on fossil fuels while also saving on energy bills. However, comprehending the technical terminology and concepts associated with solar panel systems can be overwhelming. That’s why we’re here to explain the different types and designs of solar panels, so you can decide what works best for your home.
Types of solar panels
A solar panel is a definite assembly of solar or photovoltaic cells that convert light energy into electric energy. The solar cells arranged in the system determine the types of solar panels. Every cell has distinct characteristics and appearance, with its own set of benefits. Here are three major types of solar panels:
Monocrystalline solar panels
It is also called single crystal panels designed from pure silicon crystal. They are sliced into several wafers and cut to an octagon shape to get a unique look and uniform dark blue/black color. They have excellent conversion energy, providing more space for the movement of electrons.
Polycrystalline solar panels
The polycrystalline solar panels encompass multiple silicon crystals. They are slightly less efficient than the monocrystalline panels as they have limited space for the electrons to transport. Its square shape identifies it with shining blue shades and straight edges.
Thin-film solar panels
Thin-film solar panels use photovoltaic substances composed of amorphous silicon, copper indium, cadmium telluride, and gallium selenide. These elements are deposited onto a solid surface like metal, glass, or plastic to make it lightweight and easy to install. They are less efficient but are more affordable than the other types of solar panels. It is best suited for large rooftop spaces or wide open spaces.
Major design parameters of a solar panel
A solar panel is designed with certain parameters to generate power. These design parameters of a solar panel also determine the conversion of sunlight to electricity. So let’s take a closer look.
Mounting structures
The PV arrays should be mounted on a durable structure that withstands decades of natural disasters. Rack mounts are highly preferred due to their versatility, ease of installation, and affordability.
Building-integrated PV
Solar models can also be incorporated directly into the building elements like roofs or windows. This building-integrated option will increase supply chain efficiency with lower system costs.
Inverters
Inverters are vital in covering the direct current produced by photovoltaic panels to alternate current. Alternative current is used in most equipment and local power transmission.
Factors influencing the cost of solar panels
A solar panel is built to reduce energy usage that promotes an economic sense in individuals. It means despite the cost of solar panels, it will deliver the best return on investment in a short period. Let us discuss the significant pricing factors of solar panels.
Count of panels
The more solar panels you purchase, the higher the cost. It depends on how big and efficient you want your solar system to be.
Installation
There are different types of solar panel installation, such as roof mounts and ground mounds. For instance, grounds require additional equipment to anchor the system. It will result in a higher cost of solar panels.
Roof type
Solar panels are usually installed on shingles, metal, and flat roofs. The components and level of labor for installation depend on the type of roof, which will fluctuate the final price. For instance, the shingles roof needs a flashing piece to attach the panel to the roof.
Interconnection
The cost of connecting the solar panel to the community power grid might vary depending on the requirements of the local unit and the type of meter.
Tips for choosing the best solar panels
If you are planning to buy a solar panel, it is vital to follow a proper guide to choose the right one. Here are a few tips to consider to choose the best options.
Determine your needs
The initial step in purchasing solar panels is to analyze your solar energy needs. You can review your previous electrical bills to know how much energy is consumed per month. It will help you choose the right number and size of solar panels.
Consider the type
The market primarily has three types of solar panels: polycrystalline, monocrystalline, and thin film. Each has benefits and downsides, but you can choose the one that fits your budget.
Length of the warranty
While buying solar panels, ensure to take note of the warranty offered by the manufacturer. Generally, the solar system lasts a lifetime, while a reputable manufacturer will offer a warranty for 25 years.
Solar energy has become an emerging trend in the sphere of renewable resources. In the past few years, more and more homeowners are reaping the benefits of solar panels, a valuable asset for your wallet and planet.
