Shaping the Future with Sustainable Power
Off-Grid Rooftop Solar System
Overview
- An off-grid solar system works independently without connecting to the electricity grid.
- Solar panels generate electricity during the day.
- Excess energy is stored in batteries for use at night or during power cuts.
- Suitable for remote locations where grid electricity is not available.
- Unlike on-grid systems, power supply continues even during grid outages.
Advantages
- Ideal for remote areas or places with frequent power cuts or no grid access.
- Independent from the electricity grid.
- Provides continuous power supply using solar energy and battery storage.
- No approval required from electricity authorities (like CESCOM).
- No restrictions on system capacity or installation area within the property.
Disadvantages
- Government subsidies are usually not available.
- Net metering benefits cannot be used.
- Excess electricity cannot be exported to the grid.
- Higher installation cost due to battery storage.
- Extra solar energy may be wasted if batteries are fully charged.
Components of an Off-Grid Solar System
- Solar Panels – Generate electricity from sunlight
- Mounting Structure – Supports solar panels on roof or ground.
- Off-Grid Inverter – Converts solar DC power into usable AC power.
- Solar Batteries – Store electricity for night or backup use.
- Solar Charge Controller – Regulates charging and protects batteries
- Wiring & Connectors – Connect all system components.
- Safety Devices – MCBs, DC disconnects, and protection switches.
- Optional Backup Generator – Used in some industrial setups for additional power
Why / When You Should Choose an Off-Grid System
- When grid electricity is not available in your location.
- When grid power supply is unstable or unreliable.
- When the nearest electricity connection point is very far, making grid extension expensive.
- When power outages are frequent and diesel generators are currently used.
- When rooftop space is limited but other open areas in the property are available for solar installation.
- When you want complete energy independence from the grid.
