The 3 kW on-grid solar power system is the ideal starting point for most Tamil Nadu homes: it generates roughly 10-12 units per day, offsets a typical household electricity bill, and exports surplus power to the grid through net metering.
Overview
An on-grid (grid-tied) solar system converts sunlight into electricity using rooftop solar panels and a grid-tie inverter, powering your home during the day and exporting extra units to the electricity board through a net meter. Your bill is then calculated on net consumption, which is how most households bring their power bill down dramatically.
Built on V-Guard's rooftop solar platform with high-efficiency panels and a reliable string inverter, this 3 kW package typically generates around 350-380 units per month in the western Tamil Nadu sun. Residential customers may also be eligible for central government rooftop solar subsidy under the current scheme, subject to eligibility and process; our team guides you through the application, net-meter paperwork and inspection end to end.

Generation varies with season and weather
Buying Guide: How to Choose
Match system size to your monthly consumption: roughly, every 1 kW generates 110-130 units per month here. If your bill shows 250-400 units, 3 kW fits well; 400-650 units points to 5 kW. Check your roof: you need about 100 sq. ft per kW, shadow-free through the day. If power cuts are a concern, ask us about hybrid options with battery backup. We provide a free roof survey and a generation estimate before you commit.
