3 KW · RESIDENTIAL · KERALA
The 3 kW system most Kerala homes actually need.
Full ₹78,000 subsidy. Zero advance.
3 kW is the largest system that still collects the complete PM Surya Ghar subsidy and qualifies for collateral-free bank finance. It suits a Kerala home with a monthly KSEB bill of roughly ₹2,300 to ₹2,900.

What 3 kW means
Three kilowatts, in plain numbers.
Panel capacity is measured in kilowatts. Three kilowatts on a Kerala roof generates around eleven units on an average day: enough for a family home running fans, lights, a fridge, a washing machine and an air conditioner in moderate use.
It needs roughly the footprint of a single-car garage roof, facing anywhere from south-east to south-west, free of shade between about 9 am and 4 pm.
₹31,500
Based on 1,400 units per kW per year at KSEB’s upper slab rates, giving about 4,200 units and ₹31,500 a year from 3 kW.

Is it right for you
3 kW fits most homes. Not every roof.
We would rather tell you now than after a deposit.
A GOOD FIT IF
3 kW is your size
✓ Your monthly KSEB bill runs between about ₹1,500 and ₹2,900
✓ You have 210 sq ft or more of roof clear of shade at midday
✓ The connection is domestic and in your name, or a family member’s
✓ You want the maximum subsidy without over-sizing the system
✓ You are an NRI owner and need the project run remotely
LOOK AT ANOTHER SIZE IF
3 kW is the wrong size
✓ Your bill regularly exceeds ₹3,500: look at 5 kW instead
✓ Coconut palms or a neighbouring building shade the roof at midday
✓ The roof structure needs strengthening first. We survey this too
✓ It is a commercial or LT-VII connection: subsidy rules differ
✓ You need backup through long outages. You want a hybrid with battery
Generation & savings
What 3 kW actually puts on your meter.
Kerala averages about 3.9 units per kilowatt per day across the year: about 1,400 units per kilowatt a year on a well-oriented roof. Net metering is what smooths the seasons together.

Estimates for Ernakulam. Your own figures depend on roof angle, orientation and shading, which the free survey measures rather than assumes.

IS-compliant, inspected before commissioning
KSEB net meter
The bi-directional meter that records what you export as well as what you draw. We file the application and follow it through.
Applied for and tracked by us
Monitoring
Generation on your phone: daily yield, per-string performance and fault alerts. We watch the same dashboard.
For the life of the system
Survey to switch-on, step by step.
Six stages. Each finishes before the next begins, which is why they are numbered. This is a real sequence, not a list of services.
Free site survey
We measure your roof, check shading through the day, read your last twelve months of KSEB bills and inspect the structure. On-site, or by video call if you are abroad.
Custom design & written proposal
A panel layout drawn on your actual roof, the exact make and model of every component, expected generation month by month, your subsidy, your net cost and a specific commissioning date.
KSEB approvals and subsidy registration
We register you on the National Portal, file the KSEB feasibility application, chase the approval and handle the net-metering agreement. You stand in no queue.
Installation & commissioning
Mounting structure, panels, inverter, cabling, earthing and safety checks. One team, ours, for the roof work and the electrical work both. Typically two to three days on site.
Switch on, save and monitor
The net meter goes in, the system starts generating, and we submit the commissioning certificate that releases your ₹78,000. Monitoring goes live the same day.
Support for years to come
Panel cleaning, health checks, inverter service and warranty claims. We are on call for the life of the system.
