Frequently Asked Questions
Rooftop solar systems are categorized based on how they interact with the electricity grid and whether they include energy storage (batteries). There are three main types:
- 1. On-Grid Solar System (Grid-Tied)
- 2. Off-Grid Solar System
- 3. Hybrid Solar System
Summary Comparison:
| Feature | On-Grid | Off-Grid | Hybrid |
|---|---|---|---|
| Grid Connection | Yes | No | Yes |
| Works During Power Cut | No | Yes | Yes |
| Battery Backup | No | Yes | Yes |
| Can Export to Grid | Yes | No | Yes |
| Cost | Lowest | Medium | Highest |
An On Grid solar system is connected to your local utility’s electrical grid. This setup does not require batteries to store electricity. Excess power is exported to the grid, and electricity is drawn from it when needed.
Key Features:
- • No batteries – uses the grid as backup
- • Excess energy is exported to the grid and credited to your bill
- • Draws power from the grid at night or when generation is low
Limitations:
- • Does NOT work during power cuts (it shuts down for safety reasons)
- • Dependent on the availability of the grid
Best Suited For:
- • Homes, businesses, and institutions with reliable grid supply and high electricity bills
This system operates independently of the utility grid. It includes a battery bank to store energy for use at night or during cloudy weather.
Key Features:
- • Works during power cuts
- • Complete energy independence from the grid
- • Batteries store surplus solar power
Limitations:
- • Higher upfront cost due to batteries
- • Battery maintenance and replacement over time
- • Risk of power shortage if battery is depleted and there’s no sun
Best Suited For:
- • Remote areas with no or unreliable grid access
- • Places with frequent power outages
A hybrid system combines the best of both on-grid and off-grid setups. It connects to the grid and also includes batteries for backup.
Key Features:
- • Works during power outages using battery backup
- • Can store energy and export surplus to the grid
- • Smart energy management (priority given to solar → battery → grid)
Limitations:
- • Higher cost due to battery + grid-tied inverter
- • Complex system setup
Best Suited For:
- • Urban and semi-urban homes/offices needing reliability + savings
- • Users who want backup power without a generator
Net metering is a billing mechanism that credits solar energy system owners for theelectricity they add to the grid, effectively reducing their electricity bills.
A solar rooftop system is installed on building roofs and converts sunlight into electricity, helping reduce grid dependency and electricity bills.
kWp is the peak power output under ideal conditions. kWh is the unit of energy produced or consumed, reflected in your bill.
Our Solar panels have a warranty of 25 years with a product life of around 30 years.
Inverters have a warranty of 8 years, with product life of around 8–10 years for inverters.
