From Sand to Silicon
Solar cells start as high-purity silicon, refined from quartz sand. The silicon is melted and formed into ingots, then sliced into thin wafers (180-200 micrometres). These wafers are treated to create a semiconductor that converts sunlight into electricity.
Cell to Panel Assembly
Individual cells (typically 60 or 72 per panel) are soldered together, encapsulated in EVA film, covered with tempered glass, and framed in aluminium. A junction box on the back connects the panel to your system's wiring.
Quality and Sustainability
Leading manufacturers like Trina Solar and JA Solar use automated production lines with strict quality control. Modern panels are 95% recyclable, and the energy used in manufacturing is recovered within 1-2 years of operation.
