On-Grid vs Off-Grid vs Hybrid Solar: Which Is Right for Your Home?

Every solar buyer hits the same fork in the road: on-grid, off-grid, or hybrid? The answer decides your budget, your backup capability and your subsidy eligibility — and the right choice depends on one main question: how reliable is your grid supply?

On-grid: the economical default

An on-grid (grid-tied) system works alongside your electricity connection. Solar powers your load first; surplus exports to the grid through a net meter for bill credit; the grid covers shortfalls at night.

• Cost: lowest — ₹55,000–65,000/kW residential
• Batteries: none
• Power-cut backup: none (the inverter shuts down for grid safety)
• Subsidy: fully eligible under PM Surya Ghar
• Best for: city homes and businesses with mostly reliable supply

This is what 80% of our Agra customers choose. Urban feeders are reliable enough that paying for batteries doesn't make financial sense.

Off-grid: full independence

Off-grid systems store solar energy in batteries and run your load with no grid connection at all.

• Cost: highest — ₹85,000–1,20,000/kW including batteries
• Batteries: essential; replaced every 4–6 years (lead-acid) or 8–12 years (lithium)
• Power-cut backup: total — outages don't exist for you
• Subsidy: not eligible (scheme covers grid-connected systems)
• Best for: farmhouses, remote sites, locations where a connection is unavailable or absurdly expensive

Hybrid: savings plus backup

Hybrid systems are grid-tied *and* carry a battery bank. You get net-metering credit like on-grid, and when the grid fails, batteries take over in milliseconds.

• Cost: ₹75,000–1,00,000/kW with lithium storage
• Batteries: sized to your critical loads — often smaller (and cheaper) than off-grid banks
• Power-cut backup: yes, for the circuits you choose
• Subsidy: the solar portion is eligible; batteries are not
• Best for: clinics, homes with elderly members or work-from-home setups, and areas with frequent cuts

The decision in three questions

1. Do you have a grid connection with mostly reliable supply? → On-grid. Take the subsidy, take the credits. 2. No grid access at all? → Off-grid. Size the battery bank honestly for monsoon weeks. 3. Grid available but cuts hurt you? → Hybrid. Back up what matters; export the rest.

One more honest note: if you already own an inverter-battery setup, an on-grid solar system alongside it often beats a full hybrid on cost — your existing backup keeps doing its job while solar kills the bill. We check for exactly this in our free site survey.
