Understanding Standard Solar Panel Dimensions

There's a lot to think about before committing to a solar panel installation. One often forgotten aspect of the process is choosing the right-sized solar panels for your roof.

Solar panel sizes differ depending on the model, which adds both aesthetic and practical complexity to the installation. For example, installing two large panels may not cover as much roof space as installing four smaller panels. This will affect the electricity output generated by your panels, lowering the efficiency of your system.

In this article, we'll guide you through the standard dimensions of solar panels, and advise you on how to choose the right size for your residential or commercial property.

The Mechanics Behind Solar Panels

The process begins when photons from sunlight collide with solar PV cells. This frees the electrons from within the silicone cells, creating an electrical current. This current is then directed to an inverter, which will convert it from a direct current (DC) to an alternating current (AC). Alternating current electricity is the form used by most household and commercial appliances.

Different Types of Solar Cells

There are three main types of solar panel, each with different characteristics. These are: monocrystalline, polycrystalline, and thin-film.

Monocrystalline cells are known for their efficiency and sleek appearance. Polycrystalline cells are less efficient, but are more cost-effective.Thin-film cells are lightweight and offer more flexibility, but they're less efficient than crystalline solar cells.

The Role of Inverters in Solar Systems

Inverters play a vital role in solar energy systems. They are responsible for converting the DC electricity into AC electricity, making it suitable for home use. Modern inverters offer smart features, including energy output monitoring and optimised energy production. They can also provide users with insights into system performance.

Thin-film solar panels offer a slightly different approach to solar energy. They are more flexible and lightweight when compared to crystalline models. However, they are generally less efficient than crystalline panels, more susceptible to degradation, and have shorter lifespans.

Applications of Thin-Film Panels

Thin-film solar panels are often used in installations where weight and flexibility are of greater importance. These include solar on large road vehicles, boats, and unconventional roof structures. Because they are adaptable, they can be integrated into various building materials, which greatly broadens their possibilities.

Efficiency Issues

While thin-film solar panels are undoubtedly versatile, they aren't as efficient as they crystalline counterparts. This means that more surface area is required to produce the same amount of energy, which often isn't possible in the types of spaces which thin-film panels are installed.

Technological Advances

With the advantages of thin-film panels too good to ignore, a lot of research is going into improving their efficiency. This has involved innovations in materials used and the manufacturing process of creating such technology. In time, it's expected that thin-film panels will be able to at least challenge crystalline panels in efficiency, even if they don't eclipse their levels.
