Silicon Solar Cells: The Power Generators
Silicon solar cells are key in turning sunlight into electricity. Fenice Energy uses advanced techniques to make solar panels. This helps Indian customers use solar power easily.
Monocrystalline vs Polycrystalline
It’s important to know the difference between two types of solar panels. Monocrystalline panels have about 20% efficiency but cost more. Polycrystalline panels, however, are cheaper and slightly less efficient at 15%.
Manufacturing Process of Solar Cells
The making of solar panels starts with refining silicon into thin wafers. These wafers are treated to better absorb sunlight. They are then made into either Monocrystalline or Polycrystalline panels. Fenice Energy focuses on using eco-friendly methods in this process.
Efficiency and Cost Implications
Efficiency affects a solar panel’s performance, but cost is also crucial. Fenice Energy offers efficient Monocrystalline panels at a reasonable price. But, Polycrystalline panels are a bit less efficient, which makes them more affordable upfront.
Fenice Energy offers comprehensive clean energy solutions, including solar, backup systems, and EV charging, backed by over two decades of experience.
Protective Layering: Glass Sheets and Backsheets
Solar panels last long because they have special layers for protection. These layers, like tempered glass, EVA lamination, and backsheet insulation, keep them safe from the environment.
Tempered Glass Durability
Tempered glass makes solar panels strong. It is tough and can take hits because of how it’s made. Solar panels usually have glass that is 3-4mm thick. This makes them very sturdy.
Role of EVA in Lamination
Under the glass is an important layer called EVA (Ethylene Vinyl Acetate). It sticks the glass to the solar cells and keeps out the weather. This makes solar panels work well for a long time.
Backsheet Material and Insulation
Fenice Energy knows how crucial the backsheet is for extra safety and insulation. The backsheet has layers of special plastics like PVDF or PVF. They insulate electricity and come in white or black. This part helps solar panels do their job well.
Feature | Description | Material | Benefit |
---|---|---|---|
Tempered Glass | Toughened, low iron | Glass | High transmission, durability |
EVA Layer | Lamination film | Ethylene Vinyl Acetate | Ensures sealing and encapsulation |
Backsheet | Triple layer | Polymer (PVDF/PVF) | Electrical insulation, protection |
These layers must meet high standards like IS 14286 and IEC 61215. This is to ensure solar panels protect well and last long. Fenice Energy guarantees their panels will keep at least 90% power after 10 years and 80% after 25 years.
Structural Integrity: Frames and Junction Boxes
The strength of a solar panel lies in its frame and junction boxes. Frames made from aluminum give it a strong structure. This makes them ready to face extreme weather. These frames play a big part in keeping the panel together over time.
At the same time, solar junction boxes are key for safety and efficiency. They house the electrical connections that keep the panel working. These boxes ensure the energy flow is steady and safe from environmental and electrical risks.
Fenice Energy offers a 25-year warranty, showing they trust in their solar solutions. These solutions are dependable and cost-effective for Indian users. Now, let’s look at why these parts are so important:
- Aluminum frames are resistant to corrosion. This is important for the changing climate of India.
- Solar junction boxes are designed to prevent overheating. This makes the system more efficient.
- They also use advanced sealing to protect against moisture and dust. This reduces maintenance and keeps energy flowing smoothly.
Aluminum frames and junction boxes keep solar panels safe and working well. They are crucial for a future with more solar energy.
Component | Function | Material Used | Benefits |
---|---|---|---|
Frame | Structural support | Anodized aluminum | Durability, corrosion resistance, structural integrity |
Junction Box | Electrical connections housing | Climate-resistant plastics | Protection against environmental and electrical hazards |
