On-Grid Solar System
Connected to utility grid, reduces electricity bills without battery storage requirement.
How it works:
- Solar panels convert sunlight into DC electricity during daytime generation.
- Solar inverter converts DC power into usable AC electricity supply.
- Electricity powers home, excess energy exported to utility grid automatically.
- Grid supplies electricity when solar production is insufficient or unavailable.
Off-Grid Solar System
Independent solar system with batteries, provides power without utility grid connection.
How it works:
- Solar panels generate DC electricity from sunlight during daytime hours.
- Charge controller regulates power flow safely to battery storage system.
- Batteries store energy for use during night or cloudy conditions.
- Inverter converts stored DC power into usable AC electricity supply.
Hybrid Solar System
Combines grid and battery backup for reliable and uninterrupted solar power supply.
How it works:
- Solar panels generate electricity and supply power to connected loads.
- Excess electricity stored in batteries for backup during outages periods.
- System connects with utility grid for additional power when required.
- Intelligent inverter manages solar, battery, and grid power distribution efficiently.
