1kW Solar System Price in Siliguri
A 1kW on-grid system may cost approximately ₹65,000–₹95,000 before subsidy. It is best for a small household consuming around 100–150 units per month and having limited roof space.
A 1kW plant can support energy use equal to common lights, fans, television, refrigerator and small appliances over time, but solar capacity should not be described as directly “running” every appliance simultaneously. Grid-connected energy and load behaviour depend on the inverter, grid and household consumption.
Eligible residential applicants may receive up to ₹30,000 central subsidy, bringing the effective cost to an indicative ₹35,000–₹65,000 after successful subsidy credit.
2kW Solar System Price in Siliguri
A 2kW on-grid system may cost around ₹1.15–₹1.55 lakh before subsidy. It is often suitable for homes using approximately 200–300 units per month. It may generate about 200–260 units monthly under suitable conditions.
With an indicative subsidy of up to ₹60,000, the effective investment may fall to roughly ₹55,000–₹95,000. A 2kW system is a useful middle option when the household does not need 3kW or lacks the roof area for it.
3kW Solar System Price in Siliguri
A 3kW on-grid rooftop plant may cost approximately ₹1.65–₹2.10 lakh before subsidy. It is a popular residential size because it can offset roughly 300–390 units in a typical month and may qualify for the maximum individual-household central subsidy of ₹78,000 under prevailing PM Surya Ghar slabs.
The indicative post-subsidy investment may be about ₹87,000–₹1.32 lakh. Final cost depends strongly on panel and inverter selection, elevated structures, roof conditions and metering work.
Which Size Should You Choose?
Choose 1kW if consumption and usable roof area are low. Choose 2kW for moderate consumption and a balanced initial investment. Choose 3kW if annual usage supports it, the roof is adequate and you want greater bill reduction.
Do not choose 3kW only because it receives the highest subsidy. If the home consumes much less electricity, surplus treatment and longer payback may reduce the benefit. Conversely, a 1kW plant may be too small for a family whose future load will include air conditioners, pumps or an electric vehicle.
On-Grid vs Battery System Cost
The figures above are for typical on-grid systems. Adding battery backup changes the price significantly. Battery capacity should be calculated from essential appliances, wattage and desired backup hours. Ask for a separate battery warranty, usable capacity and replacement-cost estimate.
Expected Savings and Payback
Annual financial savings equal the useful solar units multiplied by the applicable avoided electricity rate, after accounting for system losses and utility settlement rules. Because tariffs and consumption patterns vary, a vendor should not promise one universal payback period.
A responsible proposal includes:
- Annual generation estimate
- Assumed degradation and system loss
- Self-consumption and export assumptions
- Current electricity tariff used
- Maintenance and inverter replacement considerations
- Price before and after eligible subsidy

FAQs
What is the price of a 1kW solar system in Siliguri after subsidy?
The indicative effective price is about ₹35,000–₹65,000 after a successful subsidy of up to ₹30,000. The customer generally pays according to the approved process and receives subsidy after completion and verification.
How many units does a 2kW system generate?
About 200–260 units per month is a useful planning range, but actual output changes by season, shading, orientation and maintenance.
Is 3kW enough for an average home?
It may be suitable for a household consuming approximately 300–450 units per month. A 12-month bill analysis gives a better recommendation.
Does an on-grid system work during a power cut?
Normally no. Anti-islanding protection switches it off when the grid fails. Choose a compatible hybrid or backup design if outage power is required.
