How It Works
The Waaree Energies WSD-390 solar panel converts sunlight into usable electricity through advanced photovoltaic technology. Sunlight photons strike the 144 PERC polycrystalline cells embedded within the module. These cells absorb the photon energy, exciting electrons to create a flow of electric current. This direct current is then captured by the panel's internal wiring and sent to an inverter. The inverter converts the direct current into alternating current for household or grid use. The panel's anti-reflective coating ensures maximum light absorption by minimizing surface reflection losses. Its robust design allows it to operate efficiently in temperatures ranging from -40°C to 85°C. The split junction box technology reduces power loss and enhances overall system reliability. This process ensures consistent energy generation even under partial cloud cover or low-light conditions.
Photon Absorption: Sunlight photons strike the PERC polycrystalline cells to excite electrons and generate current. This process initiates the energy conversion cycle within the panel.
Current Conversion: The generated direct current flows through internal wiring to an external inverter for conversion. The inverter transforms this energy into usable alternating current for your home.
Thermal Regulation: The panel maintains efficiency across extreme temperatures using specialized thermal coefficients. This ensures stable output whether in freezing cold or intense heat.
