Do I need a TANGEDCO connection?

No — off-grid is fully independent. No application, no monthly bill.

What appliances can I run?

Lights, fans, TV, fridge, mixer, water pump — anything within your sized inverter capacity.

Lithium or tubular battery?

Lithium lasts 3× longer and weighs 60% less, but costs 2× upfront. We recommend lithium for new systems.

What about cloudy days?

We size for monsoon worst-case days — your battery holds 1–2 days of autonomy.

Can I add net-metering later?

Yes — we can convert to a hybrid system once a TANGEDCO connection arrives.

What is Off-Grid Solar (Rural / No Grid Areas)?

Off-grid solar systems are designed for homes, farms and remote sites with no grid connection or extremely unreliable supply. The system bundles solar panels, a charge controller, an off-grid inverter and a battery bank sized for your full daily load and 1–2 days of autonomy. There is no connection to TANGEDCO, so there is no net-metering paperwork, but you also cannot export surplus power. Off-grid is the right choice for new farmhouses, boundary-wall lighting, agricultural sheds and tribal settlements where extending the grid is uneconomic. We design for monsoon worst-case sun hours and use deep-cycle tubular or lithium batteries depending on budget.
