50W Single Crystal Solar Panel

50W monocrystalline solar panels are made from high-purity monocrystalline silicon wafers, with a conversion efficiency typically ranging from 18% to 22%. These panels are rated for 50W output power under standard test conditions (STC), an operating voltage of approximately 18V, and an open-circuit voltage of approximately 21.6V. Their construction, including anti-reflective coated glass, EVA encapsulation, and a weather-resistant backsheet, provides strong mechanical strength and long-term environmental tolerance. They are suitable for off-grid lighting, small home systems, surveillance equipment, and portable power generation. Typical dimensions are approximately 670 x 540 x 30 mm, and they weigh approximately 4.2 kg. The panels are typically equipped with MC4 connectors, allowing for series or parallel expansion of system capacity.
