How It Works
The JSUN 290 Polycrystalline Solar Panel converts sunlight into usable electricity through the photovoltaic effect. When photons strike the polycrystalline silicon cells, they excite electrons to create an electric current. This current flows through the internal circuit to the junction box for external connection. The panel maintains stable performance even under varying light conditions due to its design. Its 60-cell layout ensures optimal voltage and current output for standard systems. The junction box contains three diodes to prevent reverse current flow during low light. This mechanism protects the battery and ensures safe energy storage for later use.
Photovoltaic Conversion: Sunlight hits the polycrystalline cells to generate free electrons and electric current. This process transforms solar energy directly into electrical power efficiently.
Current Regulation: The junction box diodes regulate the flow of electricity to prevent reverse currents. This ensures the system remains safe and efficient during nighttime or cloudy days.
Thermal Management: The panel dissipates heat effectively to maintain performance across its wide temperature range. This thermal stability prevents efficiency loss in hot or cold environments.
