How a Hybrid Solar System Works
The system is designed to capture sunlight, power daytime loads, charge battery storage, and export surplus electricity through bi-directional net metering.
Capture solar irradiance and generate DC electricity.
Optimizes solar power generation through intelligent maximum power point tracking with efficient DC power conversion.
Routes power between appliances, battery storage, and the grid.
Stores surplus energy in lithium LiFePO4 batteries.
Measures imported and exported electricity.
Key Net Metering Guidelines at a Glance
Summary of official regulatory standards enforced by the Sustainable and Renewable Energy Development Authority (SREDA) for commercial, industrial, and institutional rooftop solar plants.
