Curious about those shiny rectangles on rooftops? နေရောင်ခြည် panel များpower homes and farms. But what goes into them? Let’s peel back the layers. We’ll look at key parts, materials, and how they come together. If you’re thinking green energy, this helps. Stick with me.
The Basic Building Blocks of a Solar Panel
Solar panels aren’t magic. They’re engineered. Each has core components. These work in sync to capture sun and make electricity.
Solar Cells: The Power Generators
Solar cells do the heavy lifting. They turn light into power via the photovoltaic effect. Most use silicon. Why? It’s abundant and effective.
Cells come in types. Monocrystalline: one crystal, efficient but pricey. Polycrystalline: multiple crystals, cheaper. Then thin-film, flexible but less powerful.
In a panel, 60 or 72 cells connect. Newer ones use half-cut cells for better output. WonVolt’s 72KUN bifacial panels pack 144 cells. They catch light from both sides. Boosts energy yield.
Protective Glass Cover
Top layer? Tempered glass. Tough stuff. Handles hail, wind up to hurricane force.
Glass stays clear. Lets max sunlight through. Anti-reflective coatings help. Dirt builds up? Rain washes it. Dry areas? Clean manually.
Thickness: around 3-4mm. WonVolt uses dual glass, 2.0+2.0mm heat-strengthened. Adds durability for rural setups.
Backsheet for Insulation and Protection
Underside needs shielding. Backsheet does that. Polymer layers block moisture, insulate electricity.
Prevents shocks. Keeps critters out. White or black, reflects light in bifacial panels.
Quality matters. Poor backsheets fade, crack. Good ones last 25+ years.
Aluminum Frame: Holding It All Together
Frame gives structure. Anodized aluminum: light, strong, rust-proof.
Seals edges. Mounts to roofs or ground. WonVolt frames: anodized alloy, 30mm thick. Handles wind, snow.
Table of main components:
| Component | Material | Role | Typical Specs |
| Solar Cells | Silicon | Convert sunlight to electricity | 144 cells in bifacial models |
| Glass Cover | Tempered glass | Protect cells, allow light in | 2-4mm thick, anti-reflective |
| Backsheet | Polymer | Insulate, protect from elements | Multi-layer, UV-resistant |
| ဘောင် | Aluminum alloy | Structural support, mounting | Anodized, 30mm depth |
These parts make panels reliable.
Key Materials in Solar Panel Production
Materials drive performance. Silicon dominates. But others play roles.
Silicon: The Star Material
Earth’s crust? Full of silicon. Second most common element. Panels use it purified.
Process starts with quartz sand. Heat to 2000°C. Makes polysilicon. Then ingots.
Monocrystalline ingots: Czochralski method. Pull crystal from melt. Efficient: up to 22%.
Polycrystalline: Melt silicon, cool in blocks. Cheaper, 18-20% efficiency.
Wafers sliced thin: 150-200 microns. Doped with phosphorus, boron for charge.
WonVolt uses N-Type TOPCon. Advanced silicon tech. Higher efficiency, bifacial gains.
Other Essential Materials
EVA Encapsulant: Ethylene Vinyl Acetate. Seals cells. Clear, flexible. Protects from vibration, moisture.
Junction Box: Plastic with diodes. Manages power flow. IP68 rated for weatherproofing.
Busbars and Ribbons: Copper or silver. Connect cells. MBB (Multi Busbar) in WonVolt: better conductivity, less shading.
Anti-Reflective Coating: Silicon nitride. Cuts reflection loss by 3-5%.
Bullet points on material benefits:
Silicon: Abundant, recyclable.
Aluminum: Lightweight, corrosion-resistant.
Glass: Durable, transparent.
Polymers: Flexible, insulating.
Shortages? Rare. Silicon supply steady. Recycling grows.
How Solar Panels Are Manufactured
From sand to panel. It’s a journey. High-tech factories handle it.
From Raw Silicon to Wafers
Quartz mined. Purified to 99.9999% silicon. Melted, crystallized into ingots.
Sawed into wafers. Diamond wire cuts precise. Waste minimal now.
Textured for light trapping. Doped for p-n junction.
Creating Solar Cells
Wafers get coatings. Screen-printed contacts. Fired in ovens.
Tested for efficiency. Sorted by grade.
TOPCon cells: Tunnel oxide layer. Cuts electron loss. WonVolt’s 580-605W panels hit high yields.
Assembling the Full Panel
Layering: Glass, EVA, cells, EVA, backsheet.
Laminated under heat, vacuum. Bonds tight.
Frame added. Junction box attached.
Tested: Flash for power, EL for cracks.
WonVolt packs 36 per pallet. Ready for shipping.
Process eco? Energy-intensive. But panels pay back in 1-2 years of use.
