🌞 Practical Insights
• Efficiency in the 21% range is typical for half-cell monocrystalline modules in this class
• Weighing nearly 30 kg, these panels are suited for rooftop or fixed ground-mount installations—not flexible setups.
• Buyer reviews suggest being cautious with extremely low-priced modules from lesser-known brands—always check warranty and support details.
