Best Solar System Under ₹1 Lakh in India 2026

Qbits warranty and service terms: Qbits public datasheets describe an expandable warranty but do not define a universal duration, remedy, registration deadline, service SLA, or exclusions. Obtain the current written terms for the exact model and sale before relying on a headline claim. ALMM and inverter compliance: MNRE’s current ALMM page publishes solar PV module and cell lists, not an inverter list. Verify the inverter’s exact model documents and applicable scheme or DISCOM requirements separately.

A solar system for under ₹1 lakh, is it real? The answer depends on whether you are counting the gross price or the net price after the PM Surya Ghar subsidy, and on the quote you actually receive. This guide uses the MNRE benchmark as a reference (₹50,000 per kW for the first 2 kW and ₹45,000 for each additional kW, from the scheme’s residential guidelines), because we found no dated, sourced national price range for small systems.

Direct answer. At the MNRE benchmark, a net budget of ₹1 lakh covers up to about 3 kW: 1 kW is ₹20,000 net, 2 kW is ₹40,000 net and 3 kW is ₹67,000 net after the PM Surya Ghar subsidy. Real quotes differ from the benchmark, so apply the ₹1 Lakh Solar Budget Checklist to every quote: ALMM compliance, certified panels, full BOS scope, GST invoice, and empanelled installer.

What ₹1 Lakh Actually Buys in Indian Solar in 2026

The ₹1 lakh budget means different things depending on whether you apply it before or after subsidy:

The most important variable is subsidy. The difference between claiming and not claiming PM Surya Ghar subsidy on a 2 kW system is ₹60,000, which is 60% of its benchmark cost. The PM Surya Ghar subsidy guide breaks down the exact amount for every capacity.

Three Solar System Options Under ₹1 Lakh (Net Cost)

The figures below apply the MNRE benchmark and a generation of 1,450 to 1,550 units per kW a year (the formula and approximate state values are in our generation guide). Savings are at an assumed ₹7 per unit.

Option 1: 1 kW On-Grid

Suits: a 1 BHK without AC, consumption below about 150 units a month, very limited roof space. It covers only part of a typical 1 BHK bill if consumption is higher. Check your own bills.

Option 2: 2 kW On-Grid

Suits: a home with one AC or 200 to 250 units a month of consumption, using the generation above. It cannot back up the home during power cuts, and it cannot run two ACs at once without grid supply.

This is also the capacity where many residential turnkey EPC installers concentrate their standard packages, since it balances subsidy efficiency with load coverage for small homes.

Option 3: 3 kW On-Grid

Suits: a larger home with higher consumption. At the benchmark, 3 kW is ₹67,000 net, and the extra ₹27,000 over 2 kW buys 50% more generation, so if your consumption supports it, 3 kW has a similar payback. Match the size to your bills, not to the budget alone.

The detailed 2 kW cost reference points are in the 2 kW solar system price guide, and the 3 kW breakdown is in the 3 kW solar system price guide.

The ₹1 Lakh Solar Budget Checklist

Every solar buyer on a tight budget should verify these five items. Missing any one of them can turn a “cheap” deal into an expensive mistake:

Budget vs Quality: What the Price Gap Means

At a ₹1 lakh budget level, every rupee matters. We found no dated sourced data on lifetime generation or failure rates by quality tier, so this guide does not publish a tier table. Compare the lines that can differ between two quotes of the same capacity:

Compare the price difference with the annual-generation difference using the formula in our generation guide, and with the written warranty and remedy.

State Subsidies: Ask Before You Count on Them

The central PM Surya Ghar subsidy is ₹30,000 for 1 kW, ₹60,000 for 2 kW and ₹78,000 for 3 kW and above. Some states add their own top-ups, and those amounts, the eligible categories and the conditions are set by each state’s orders. We found no sourced current state-wise amounts, so no state table is published here. Ask your state nodal agency or DISCOM whether a top-up applies and whether it can be combined with the central subsidy.

Common Mistakes in the Under-₹1 Lakh Segment

• Choosing gross price over net price: The correct comparison is net cost after subsidy. A system that is not ALMM-listed forfeits the subsidy, so a lower gross price can mean a higher effective cost.
• Buying from non-empanelled installers: Many local electricians offer “solar installations” outside the PM Surya Ghar framework. These cannot process the subsidy and the work quality is unverified.
• Choosing a 1 kW system to stay “cheap” when 2 kW is the right fit: If your consumption needs more than 1 kW generates, a 1 kW system covers only part of it; compare the payback of each size from your own bills.
• Overbuying: Buyers with low consumption who are pushed to buy a larger system are overbuying. Right-sizing matters both ways. The 1 kW solar system price guide helps identify when 1 kW is genuinely sufficient.

Qbits model documentation

The budget solar buyer deserves a model-specific written warranty and a properly protected enclosure, just like the large installation, and should not get a lesser product because the system is smaller. For 1 to 2 kW, Qbits’ published catalogue lists the QB 1.5 to 4.0KTLS single-phase range, which starts at 1.5 kW. Pick the exact model for your array size and check its current datasheet at datasheet library.

• Hybrid Inverters: Review current QBH model documents and confirm the exact battery, firmware, PV, backup-output, transfer, communication, warranty and project requirements in writing.
• String Sizing Calculator: Verify your 1–2 kW string configuration and panel layout before ordering.
• Authorised Service Partners: Search the current directory, then confirm partner status, service scope, coverage, response process and commercial terms for the location.

Contact Qbits and share your electricity bill so the right inverter model can be matched to your actual consumption. Qbits sells inverters through dealers and publishes no price, so ask for a dated quote for the exact model.
