Off-Grid Solar System – Self-Reliable Power Wherever the Grid Can’t Reach
An Off-Grid Solar System (also called a standalone solar system) generates electricity from sunlight and stores it for use when needed — without being connected to the public utility grid.
Off-grid Solar Systems are best for homes in remote or rural areas where there is no electricity connection from the main grid. In such places, getting a grid line installed can be expensive or sometimes not possible, so an off-grid setup becomes a reliable solution.
They are also useful in locations where the electricity supply is very weak or unreliable. If you face frequent power cuts, low voltage, or very limited hours of electricity, an off-grid system can give you a steady power supply without depending on the grid.
However, if your grid connection is stable and you qualify for Government subsidies, an on-grid solar system is usually more affordable and cost-effective. It reduces your electricity bill and requires less battery investment compared to an off-grid setup.
Key Components of the System
Solar Panels
Installed on your roof (usually south-facing), absorb sunlight and convert it to DC
Off-Grid Inverter
Converts DC power (from panels or batteries) into AC power usable by household appliances.
Charge Controller and Battery
Manages power flow from panels to batteries and stores excess energy for use at night or during low sunlight.
Balance Of Supply
weather-resistant frameworks, DC & AC cables, combiner boxes, earthing, connectors, lightning protection
Key Features & Benefits
Continuous Power Supply
You store solar-generated power in batteries, allowing electricity usage during low-sunlight periods or power cuts.
Self-Sufficiency
No reliance on the grid means complete energy independence—even when the grid is down or unavailable.
Higher Initial Costs
The inclusion of batteries increases upfront investment compared to grid-connected systems.
Subsidies and Policy
Only on-grid solar systems are eligible for MNRE and UPNEDA subsidies; off-grid systems don’t qualify.
