2kW Solar System for Home: Price, Output & Subsidy in India (2026)

The Short Answer

A 2kW solar system costs ₹1,10,000–₹1,40,000 before subsidy and ₹50,000–₹80,000 after the PM Surya Ghar subsidy of ₹60,000. It generates 8–10 units per day — suitable for a 2 BHK home with moderate electricity usage (₹1,000–₹2,000/month bill). Requires ~200 sq ft of roof space and 4 standard panels.

2kW Solar System Price Breakdown

Component	Cost Range
Solar panels (4 × 540W mono)	₹36,000–₹48,000
On-grid inverter (2kW)	₹20,000–₹28,000
Mounting structure	₹8,000–₹12,000
Wiring, protection, earthing	₹6,000–₹8,000
Installation labour	₹5,000–₹8,000
Net metering & DISCOM fees	₹2,000–₹5,000
GST (13.8%)	₹12,000–₹16,000
Total (before subsidy)	₹1,10,000–₹1,40,000
PM Surya Ghar subsidy	−₹60,000
Net cost (after subsidy)	₹50,000–₹80,000

The 2kW tier gets the maximum per-kW subsidy rate (₹30,000/kW × 2 = ₹60,000), making it one of the best value-for-money sizes.

Daily and Monthly Output

Period	Output	Bill Savings (at ₹6–₹10/unit)
Per day	8–10 units	₹48–₹100
Per month	240–300 units	₹1,440–₹3,000
Per year	2,900–3,600 units	₹17,400–₹36,000

A 2kW system typically offsets 60–80% of a 2 BHK household's electricity consumption — enough for fans, lights, TV, refrigerator, and small kitchen appliances but not enough for regular AC usage.

What Can a 2kW System Run?

A 2kW system handles moderate household loads comfortably:

Appliance	Wattage	Hours/day	Daily Units
LED lights (8)	80W	6	0.5
Ceiling fans (3)	210W	10	2.1
Refrigerator (190L)	150W	8 (compressor)	1.2
TV (LED 42")	80W	5	0.4
WiFi router	15W	24	0.4
Washing machine	500W	1	0.5
Mixer grinder	750W	0.3	0.2
Mobile + laptop charging	85W	5	0.4
Total			5.7 units

This leaves 2–4 units daily surplus for net metering credits. For AC or geyser, upgrade to 3kW or 5kW.

Space and Installation

Panels: 4 × 540W monocrystalline panels
Roof area: ~200 sq ft (shadow-free, includes spacing)
Weight: ~60–80 kg total
Installation time: 1 day for most roofs
Orientation: South-facing at 10–15° tilt (optimal for India)

A 2kW system fits comfortably on most independent house terraces. For apartments, you need ~200 sq ft of allocated space — check with your housing society.

Subsidy and Payback Period

2kW hits the sweet spot for subsidy — it gets the highest per-kW rate under PM Surya Ghar:

Subsidy: ₹30,000/kW × 2kW = ₹60,000
Effective subsidy coverage: 43–55% of system cost

Payback calculation:

Tariff	Net Cost	Annual Savings	Payback
₹5/unit	₹65,000	₹15,000	~4.3 years
₹7/unit	₹65,000	₹21,000	~3.1 years
₹10/unit	₹65,000	₹30,000	~2.2 years

The 2kW system offers arguably the best payback of any size because of the maximum subsidy rate.

2kW vs Other Sizes: Should You Go Bigger?

	1kW	2kW	3kW
Cost after subsidy	₹30K–₹50K	₹50K–₹80K	₹72K–₹1.12L
Daily output	4–5 units	8–10 units	12–15 units
Runs AC?	No	No	1 unit, limited hours
Best monthly bill	₹500–₹1,000	₹1,000–₹2,000	₹2,000–₹3,500

Rule of thumb: If your monthly bill is under ₹2,000, 2kW is the sweet spot. If it is ₹2,000–₹3,500, the extra ₹20,000–₹30,000 for 3kW is worth it because of the additional subsidy kW at ₹18,000/kW.

Who Should Choose 2kW?

2 BHK homes without AC or with minimal AC use
Monthly bills of ₹1,000–₹2,000
Budget-conscious buyers who want strong subsidy coverage (~50% of cost)
Small families (2–3 members) with standard appliance usage
Apartment flat owners with ~200 sq ft of rooftop allocation

Common questions

What is the price of a 2kW solar system in India?

A 2kW on-grid system costs ₹1,10,000–₹1,40,000 before subsidy. After PM Surya Ghar subsidy of ₹60,000 (₹30,000/kW × 2), your net cost is ₹50,000–₹80,000 including panels, inverter, mounting, installation, and net metering.

How many units does a 2kW solar system produce per day?

A 2kW system produces 8–10 units (kWh) per day on average. Monthly output is 240–300 units. This offsets ₹1,440–₹3,000 per month depending on your electricity tariff.

How many panels are needed for 2kW solar?

With 540W monocrystalline panels, you need 4 panels (4 × 540W = 2,160W). These require approximately 200 sq ft of shadow-free roof space.

Can a 2kW solar system run an air conditioner?

Not effectively. A 1-ton inverter AC draws 700–1,000W, consuming most of the 2kW capacity and leaving little for other appliances. For AC usage, a 3kW or 5kW system is recommended.

What is the payback period for a 2kW solar system?

2–4 years depending on your electricity tariff. At ₹7/unit, a 2kW system with ₹65,000 net cost (after subsidy) pays back in about 3 years. The 2kW size offers the best payback ratio due to the maximum per-kW subsidy rate.

Is 2kW enough for a 2 BHK house?

For a 2 BHK without AC, yes. A 2kW system generates 8–10 units/day, covering fans, lights, fridge, TV, washing machine, and small appliances. If your monthly bill exceeds ₹2,000 or you use AC regularly, consider upgrading to 3kW.
