Solar system types

On-grid, hybrid or battery-based — which suits you?

See how each system works, with a simple diagram and the benefits you get.

On-grid

Solar + TANGEDCO grid, with net metering. No battery.

Simplified single-line diagram (SLD) for understanding only — not an engineering drawing. The actual SLD is prepared after a site survey.

How it works

  1. 1Panels convert sunlight into DC power during the day.
  2. 2The on-grid inverter converts DC to AC and synchronises with the EB supply.
  3. 3Your home uses solar power first; any shortfall comes from the grid.
  4. 4Extra solar power is exported, and the net meter records import and export for billing adjustment as per TANGEDCO rules.

Your benefits

  • Lowest upfront cost — no battery to buy or replace
  • Largest reduction in EB bill through net metering
  • Eligible residential systems can apply for PM Surya Ghar + TN subsidy
  • Very low maintenance — mainly panel cleaning and periodic checks
Best for: Homes and businesses with reliable EB supply that want the biggest bill savings.
Good to know: During a power cut the inverter switches off automatically for line-worker safety (anti-islanding), so there is no backup.
