Maximum Savings, Government-Backed
On-grid (grid-tied) solar is the right fit for most homes with a reliable electricity connection — lowest cost, fastest payback, and eligible for both the central and Uttar Pradesh state subsidy.
A System That Uses the Grid as Its Battery
An on-grid system connects directly to your existing electricity connection through a bidirectional net meter — no battery bank required, since the grid absorbs your surplus and supplies your shortfall.
No Battery Needed
The grid absorbs your surplus by day and supplies your shortfall by night — no battery bank to buy or maintain.
Bidirectional Net Meter
Tracks the units you export and import separately — the exact basis of the credit on your electricity bill.
Lowest Cost, Fastest Payback
The smallest upfront investment of any solar option, with the shortest payback period.
From Rooftop to Bill Credit
Sunlight capture
Photovoltaic cells in the panels absorb sunlight and generate DC electricity, in proportion to how much sun hits the roof through the day.
DC to AC conversion
The solar inverter converts that DC output into grid-compliant AC power, synchronized to the grid's frequency and voltage.
Net meter tracking
A bidirectional net meter records both the units your system exports to the grid and the units you import from it.
Daytime consumption
Through the day, your home draws power straight from the inverter — solar first, grid only for any shortfall.
Surplus export
Any generation beyond what your home is using flows back into the grid through the net meter, earning export credits.
Night / low-light import
After sunset or on overcast days, your home draws from the grid as usual — offset against the credits you've built up.
Components Explained
Solar Panels
Mounted on the roof, typically facing south for maximum yield. Panels are built from a few core cell technologies:
- •Monocrystalline — cut from a single silicon crystal, the highest efficiency and most compact option, the standard for residential roofs with limited space.
- •Polycrystalline (multicrystalline) — made from multiple silicon crystals, slightly lower efficiency at a lower cost.
- •Bifacial — generates from both the front and rear face, useful where rear-side reflected light can be captured too.
- •TOPCon — an ultra-thin tunnel oxide-passivated contact layer, a newer high-efficiency cell technology.
Solar Inverter & MPPT
Converts DC from the panels into usable AC power. Every modern inverter uses Maximum Power Point Tracking (MPPT) — it continuously adjusts the electrical operating point of the panels as sunlight and temperature shift through the day, so you always harvest the most power actually available rather than a fixed, suboptimal draw.
Mounting Structure
Rust-resistant, hot-dip galvanized structure that holds panels securely at the correct tilt angle for your roof and location.
Bidirectional Net Meter
Replaces your existing meter to separately track units exported to and imported from the grid each month — the basis for your net-metering credit.
Combiner Boxes & BOS
DC and AC combiner boxes, cabling, earthing, and lightning protection — the balance-of-system components that keep everything safe and code-compliant.
Central + Uttar Pradesh State Subsidy, Stacked
Grid-connected residential systems qualify for two subsidies at once — we handle both applications end-to-end.
Central Subsidy — PM Surya Ghar Muft Bijli Yojana
A fixed, nationwide subsidy for grid-connected residential systems, credited directly to your bank account after installation and net-metering approval.
State Subsidy — Uttar Pradesh (UPNEDA)
Uttar Pradesh runs an additional state-level subsidy through UPNEDA, on top of the central amount — we file both applications for you.
Did you know? The state governments of Uttar Pradesh and Delhi offer additional subsidies to homeowners on top of the central government's subsidy.
Uttar Pradesh (UPNEDA): ₹15,000/kW for 1-2 kW systems, capped at ₹30,000 for systems 2 kW and above.
Delhi: ₹10,000/kW, capped at ₹30,000.
Based on the rates above, here's the combined subsidy by system size:
| System Size | Central Subsidy (All Other States) | Total in Uttar Pradesh | Total in Delhi |
|---|---|---|---|
| 1 kWp | ₹30,000 | ₹30,000 + ₹15,000 = ₹45,000 | ₹30,000 + ₹10,000 = ₹40,000 |
| 2 kWp | ₹60,000 | ₹60,000 + ₹30,000 = ₹90,000 | ₹60,000 + ₹20,000 = ₹80,000 |
| 3 kWp | ₹78,000 | ₹78,000 + ₹30,000 = ₹1.08 lakh | ₹78,000 + ₹30,000 = ₹1.08 lakh |
| 4 kWp | ₹78,000 | ₹78,000 + ₹30,000 = ₹1.08 lakh | ₹78,000 + ₹30,000 = ₹1.08 lakh |
| 5 kWp | ₹78,000 | ₹78,000 + ₹30,000 = ₹1.08 lakh | ₹78,000 + ₹30,000 = ₹1.08 lakh |
| 10 kWp | ₹78,000 | ₹78,000 + ₹30,000 = ₹1.08 lakh | ₹78,000 + ₹30,000 = ₹1.08 lakh |
Figures are illustrative based on published central and state subsidy rates as of 2026. Your exact eligible amount is confirmed during your free site visit, and both applications are filed on your behalf.

What's the ROI on an On-Grid System in Lucknow?
Solar isn't just a bill reducer — it's an investment. Here's how the payback stacks up over a 25-year system life.
What the ROI depends on
- • The panel and inverter brand you choose
- • How much unobstructed sunlight your roof receives
- • Your DISCOM's domestic electricity tariff slab
Assumptions used below
- • ~1,400 units/kW generated per year in Lucknow's sun conditions
- • Electricity tariffs rise ~4-5% every year
- • Panel output degrades ~0.7% per year, well-maintained
Based on Lucknow's indicative net cost (after combined central + UP subsidy) from the pricing table above, here's the projected return over a 25-year system life:
| System Size | Net Cost in Lucknow (After Subsidy) | Est. Savings Over 25 Years | Return on Investment |
|---|---|---|---|
| 2 kW | ₹95,000 | ₹8.48 lakh | ~8.9x |
| 3 kW | ₹1.07 lakh | ₹12.72 lakh | ~11.9x |
| 4 kW | ₹1.62 lakh | ₹16.96 lakh | ~10.5x |
| 5 kW | ₹2.22 lakh | ₹21.19 lakh | ~9.5x |
| 10 kW | ₹4.77 lakh | ₹42.39 lakh | ~8.9x |
In other words, a typical 3 kW on-grid system in Lucknow returns roughly ₹12 for every ₹1 spent net of subsidy, over its 25-year life — and it keeps generating free electricity well after the payback period ends. Your free site visit gives you exact numbers based on your roof and consumption.
Figures are illustrative estimates based on typical Lucknow generation and UP domestic tariff trends, not a guarantee. Actual savings depend on your consumption pattern, roof orientation, and DISCOM tariff changes over time.

Built for Maximum Financial Return
Lowest Cost per kW
No battery bank needed, so on-grid systems have the lowest upfront cost and fastest payback of any solar option.
Central + State Subsidy
Grid-connected residential systems qualify for both the PM Surya Ghar central subsidy and the Uttar Pradesh state subsidy — up to ₹1,08,000 combined, which we file for you.
Net-Metering Credits
Export surplus units back to the grid during the day and draw from it at night — your bill nets the difference.
Fast Payback
Most residential on-grid systems pay back their net cost in 2-4 years, then generate savings for the system's remaining life.
Minimal Maintenance
No batteries to service or replace — just periodic panel cleaning and an annual inverter health check.
25-Year System Life
Panels are built to perform for 25+ years; inverters typically need replacement only once, around year 10-12.
One limitation to know: on-grid systems shut off automatically during a grid power cut, by design — this protects utility workers on the line. If uninterrupted backup power matters to you, ask us about a hybrid or off-grid system instead.
From Site Survey to Switched-On
Site Assessment
Our engineer surveys your roof for shading, structural load capacity, and optimal south-facing orientation and tilt.
Mounting Installation
Corrosion-protected structures are secured to the roof; panels are clamped in place per manufacturer spec.
Electrical Integration
DC strings route through combiner boxes to the inverter; AC output connects through a secondary combiner box to your new bidirectional net meter.
Earthing & Lightning Protection
Dedicated earthing rods and lightning arresters ground the system and divert surge energy safely, per electrical safety code.
Commissioning & Monitoring
We verify voltages and phase sequences, coordinate DISCOM net-metering approval, and enable app-based generation monitoring.

On-Grid Solar FAQs
No. When the grid goes down, on-grid inverters automatically shut off — this is a safety feature (anti-islanding protection) required by DISCOM regulations, protecting utility workers repairing the line. If backup power matters to you, ask about a hybrid or off-grid system instead.
