On Grid Solar System in Kerala for Homes & Businesses
Generate solar electricity during the day while staying connected to the KSEB electricity grid.
An on grid solar system—also called a grid-connected or grid-tied solar system—uses rooftop solar panels to power your property first. Depending on the applicable metering arrangement, surplus generation can be exported to the grid, while electricity can be drawn from KSEB when your solar system is not producing enough power.
FGE Solar provides complete on grid solar system installation in Kerala, including site assessment, system design, rooftop installation, KSEB coordination, commissioning and eligible residential subsidy assistance.

How It Works
How an On Grid Solar System Works
An on the grid solar power system works alongside your existing electricity connection rather than replacing it completely.
During daylight hours, rooftop solar panels convert sunlight into DC electricity.
The solar inverter converts this DC electricity into AC electricity that your home or business can use.
The electricity generated by solar is first used by your appliances and other electrical loads.
When solar generation exceeds your immediate requirement, surplus electricity can be exported through the applicable grid-metering arrangement.
When solar generation is lower than your electricity demand—or at night—the property draws the required electricity from the KSEB grid.
An on-grid system normally does not contain a battery.
That is one reason an on grid solar system in Kerala usually has a lower initial cost than an equivalent hybrid or off-grid system.

Net Metering
How KSEB Net Metering Works with On Grid Solar
In a grid-connected renewable-energy system, solar electricity generated at the consumer's premises is first used to meet the property's electricity requirement.
When solar generation exceeds immediate consumption, surplus electricity can be exported to the grid.
The bidirectional meter records:
Electricity imported from KSEB
and
Electricity exported from the solar system
The applicable energy accounting, billing and settlement are governed by current KSEB and KSERC rules.
What Happens at Night?
Solar panels do not generate electricity at night.
An on-grid property therefore draws electricity from KSEB when solar generation is unavailable.
What Happens During Cloudy Weather?
Solar panels can still generate electricity under diffuse sunlight, but output may be lower.
The grid automatically supplies the remaining electricity requirement.
What Happens During a Power Cut?
A standard on grid rooftop solar system normally shuts down during a grid outage.
This anti-islanding safety feature helps prevent the solar system from energising grid lines while utility personnel may be working on them.
If backup electricity during outages is important, consider a hybrid system with suitable battery storage.
FAQ
Frequently Asked Questions About On Grid Solar Systems
An on grid solar system is a solar-power system connected to the electricity grid. Solar panels generate electricity during daylight hours, the property uses that electricity first, and the grid supplies additional electricity when required. Surplus generation can be exported according to the applicable grid-metering arrangement.
It can be a good choice for homes with a reliable KSEB connection that primarily want to reduce grid electricity consumption without investing in battery storage. The right choice still depends on electricity consumption, roof conditions, outage frequency and backup requirements.
Indicative complete on-grid installations can range from approximately ₹60,000–₹85,000 for 1 kW, ₹1.70–₹2.30 lakh for 3 kW and ₹2.70–₹3.60 lakh for 5 kW before applicable subsidy. Actual prices vary according to equipment and site conditions.
An indicative 3 kW system can cost approximately ₹1.70–₹2.30 lakh before subsidy. Eligible residential installations may qualify for up to ₹78,000 of Central Financial Assistance under the current PM Surya Ghar structure.
