On-Grid Solar System Buying Guide – Prices, Subsidy & Complete
Overview
An on-grid solar system (also called grid-tied solar) connects directly to your
local electricity grid.
It allows you to use solar power during the day and export surplus electricity back
to the grid
through net metering. At SolarWiser, we design high-efficiency rooftop systems that
reduce your
electricity bill by up to 90% while offering long-term energy security.
What Is an On-Grid Solar System?
An on-grid system operates without batteries. Solar panels generate DC electricity,
which is converted into AC power using a solar inverter. Excess electricity is
exported
to the grid via a bi-directional net meter.

Limitations
During a grid power outage, an on-grid system automatically shuts down due to
anti-islanding protection. This ensures safety for utility workers but means
your home will not receive solar power during blackouts.
Estimated ROI Example (3 kW System)
A 3 kW SolarWiser system can generate approximately 4,200–4,350 units annually.
With an average tariff of ₹10–₹12 per unit and 3–5% yearly tariff increase,
homeowners can save ₹14–₹18 lakhs over 25 years. The initial investment
typically recovers within 3–5 years.
