What are solar modules?
Solar modules, sometimes called solar panels, convert sunlight into electricity. They are composed of several interconnected solar cells that gather solar energy and transform it into electrical energy using the photovoltaic effect. These modules are utilized in various applications to create clean, renewable energy.
Solar modules are commonly put on rooftops, ground-mounted systems, and large solar farms to generate residential, commercial, and industrial electricity. They can function autonomously in off-grid settings or be linked to the electrical grid. Solar modules are important in lowering fossil fuel dependency and promoting sustainable energy options.\
Types of Solar Panels
There are many different kinds of solar panels, and each has special qualities and uses. There are three main categories of solar panels:
- 1. Monocrystalline Solar Panels:
Monocrystalline solar panels are distinguished by their high efficiency and elegant shape. They are composed of a single crystal structure. They usually have a uniform appearance and are black in color due to the use of single-crystal silicon. Cutting silicon ingots into thin wafers, which are subsequently integrated into cells, is the manufacturing process.
These panels are perfect for installations with limited space because they have the maximum energy production per square meter. They continue to be dependable and efficient even in high-temperature and low-light situations.
- 2. Polycrystalline Solar Panels:
Polycrystalline solar panels consist of several silicon crystals fused together. They are typically blue in colour and feature speckled patterns. The production technique is less expensive than that of monocrystalline panels, hence they are more inexpensive.
While polycrystalline panels are slightly less efficient than monocrystalline panels, they provide a decent cost-performance ratio. They are ideal for large-scale installations when space is not an issue.
A commercial solar farm in an open field can use polycrystalline panels to increase energy production while keeping costs down.
- 3. Thin-Film Solar Panels:
Thin-film solar panels are created by depositing thin layers of photovoltaic material onto a substrate (e.g. glass, plastic, metal). They are flexible, lightweight, and may be made in a variety of forms and sizes.
These panels have lesser efficiency than crystalline panels, but they are useful in applications where flexibility and weight are crucial. They operate well in diffuse lighting and high temperatures.
Thin-film panels are suited for usage on curved surfaces, such as car roofs or unconventionally designed buildings.
What Are Solar Panels Made Of?
Understanding the materials that make up solar panels is critical for determining their longevity and performance. Solar panels typically include the following components:
- 1. Photovoltaic (PV) cells:
Solar panels rely on photovoltaic (PV) cells, which are typically constructed of semiconductor materials like silicon. When sunlight hits these cells, it excites electrons, resulting in an electric current. PV cells use different forms of silicon, including monocrystalline, polycrystalline, and amorphous silicon. The type of silicon used influences the efficiency and durability of the cells. Unimacts Solar Modules use high-quality monocrystalline silicon cells for optimal efficiency and endurance.
- 2. Glass:
The top layer of the panel is typically constructed of tempered glass. This glass protects the solar cells from external elements like rain, snow, and hail while yet enabling maximum light penetration. Tempered glass is sturdy and resistant to breaking. It also has anti-reflective coatings, which improve light absorption and prevent energy loss. In hailstorm-prone areas, Unimacts solar modules' tempered glass ensures they remain undamaged and functional.
- 3. Encapsulant:
This layer protects solar cells from moisture and mechanical harm. Ethylene-vinyl acetate (EVA) is a common encapsulant material for solar panels. The encapsulant protects the PV cells, preventing moisture intrusion and maintaining long-term performance.
- 4. Backsheet:
The backsheet, located at the bottom of the panel, provides additional protection and insulation. It is often comprised of tough polymer materials that shield the panel from environmental degradation. The backsheet prevents moisture and debris from accessing the panel, extending the life of the internal components. In humid locations, a strong backsheet in Unimacts solar modules helps to prevent moisture-related concerns, extending the panel's life.
- 5. Frame
The aluminum frame binds panel components together and allows for easy placement on various configurations. It provides structural support while also protecting the edges of the glass and PV cells. Aluminum frames are lightweight, corrosion-resistant, and can survive extreme weather conditions. The robust aluminum frames allow them to endure wind loads and other mechanical pressures.
How Long are Solar Panels Good For?
