Solar Electric STKP-60-250 250W Polycrystalline Solar Panel
Model STKP-60-250 | Polycrystalline | 60 Cell | Monocrystalline | 1000V System Voltage
Product Overview
The Solar Electric STKP-60-250 is a high-quality 250Wp polycrystalline solar panel built for dependable energy production. It combines a 60-cell layout with a strong glass/glass construction concept, designed to improve durability, moisture resistance, and long-term performance. The panel offers 18.2% efficiency, making it a practical choice for residential and commercial solar applications. With a 15-year product warranty and strong performance warranty terms, it is engineered for projects that value stable output and long service life. Its robust build, MC4 connector, and wide operating temperature range support reliable installation in demanding environments.
Key Benefits
Durable Glass/Glass Design: The back-glass construction improves protection against UV exposure, moisture, ammonia, and salt corrosion.
Strong Power Output: The module delivers 250Wp rated power for efficient solar generation across many system types.
Long-Term Warranty Support: A 15-year product warranty and performance coverage support confidence in long-term operation.
Stable Electrical Performance: Low temperature coefficients help maintain predictable output in changing weather conditions.
Easy Installation: MC4 connectors and standard cable sizing support straightforward solar system integration.
Built for Harsh Conditions: The panel is rated for wide operating temperatures and strong mechanical system voltage requirements.
How It Works
This solar panel converts sunlight into usable DC electricity through its polycrystalline cell structure. The 60-cell module produces power efficiently under standard operating conditions. Its electrical values, including voltage, current, and temperature coefficients, define how the panel performs during real-world operation. The glass/glass construction adds mechanical resilience, while the edge-seal protection helps reduce moisture-related degradation. This makes the module suitable for long-term installations where consistent output and environmental protection matter.
Solar Conversion: Sunlight strikes the polycrystalline cells, which generate direct current electricity. The panel’s 250Wp rating reflects its peak output under test conditions.
Performance Stability: The module uses temperature coefficients to show how output changes as heat rises. This helps installers estimate seasonal performance more accurately.
Protection and Longevity: Glass on both sides and the edge-seal design help protect the cells from moisture and harsh weather. That support contributes to long service life and reduced degradation.
