Blog Highlight – Explore our comprehensive guide on Solar Panel Parts to understand the components that power solar energy systems efficiently and sustainably.
Congratulations on deciding to use solar power! You’re making a smart choice to go green and use a more sustainable energy source. Many people in the Philippines are already benefiting from solar power and saving money on their power bills.
Now, like any curious person, you probably want to know how solar panels work. To understand it better, you need to know about the different parts that work together to turn sunlight into electricity.
In this blog, we’ll talk about the different components of a solar panel in simple terms. So, let’s dive in!
Understanding the Different Parts of a Solar Panel
A solar panel has many parts that work together to absorb sunlight, turn it into electricity, and power our homes and appliances. Here are the main parts:
- Solar cells
- Backsheet
- Junction box and wiring
- Frame and mounting structure
- EVA encapsulation and tempered glass
These are the basic elements of a solar panel, and they all work together to generate power. The solar cells produce energy, which the junction box regulates. The back sheet protects the panels from the environment, while the frame and mounting structure make sure the panels are strong and flexible. Additionally, tempered glass and EVA encapsulation help absorb solar power efficiently without losing any and protect the panels.
Now, let’s talk about each solar panel part in more detail
1. Solar Cells
Solar cells, also known as panels, are like the heart of a solar system. There are different types, such as monocrystalline and polycrystalline panels, but monocrystalline panels are used most often because they are slim and perform well. Single silicon cells are connected together to create a panel, which is the face of the solar system that absorbs sunlight.
2. Back Sheet
The back sheet is placed behind the solar panel and acts as a protective layer. It shields the cells from things like moisture and harsh weather. Made of materials like polymers, the back sheet also works as an insulator, preventing electricity from leaking out. This helps the solar panel stay efficient and durable over its life.
3. Junction Box and Wiring
The junction box is an important part that manages the electrical connections inside the solar panel. It holds the wiring, connects the solar cells, and ensures electricity flows properly to the external circuit. The junction box also protects the panel from getting too hot by releasing excess heat. In many cases, it has a bypass diode to control electricity flow and reduce losses caused by shading.
4. Frame and Mounting Structure
A solar panel’s frame and mounting structure give it the support it needs. Usually made of aluminum, the frame not only holds the weight of the solar panel but also protects it from physical stress and the environment. The mounting structure keeps the solar panel in place, whether it’s on a rooftop, the ground, or another surface, making sure it gets the most sunlight for maximum energy production.
5. EVA Encapsulation and Tempered Glass
Inside the solar panel, there is a layer of ethylene-vinyl acetate (EVA) that acts like a protective barrier for the cells. This layer shields the cells from external elements and helps keep the panel’s structure intact. On top of the EVA layer, tempered glass is added for extra protection and improved durability. Tempered glass is strong and resistant to impact, making sure the solar panel lasts even in challenging weather.
Final Thoughts
We hope you now have a fair idea of the intricate solar panel assembly parts. Understanding how a solar panel works is like getting to know one of mankind’s remarkable inventions that has forever changed our dependence on fossil fuels and enabled us to be more energy-resilient.
