What Is Included in a Complete Rooftop Solar Price?
A proper quotation should cover more than solar modules. Ask whether it includes:
- DCR/ALMM-compliant solar panels where required
- On-grid, off-grid or hybrid inverter
- Galvanized mounting structure suitable for the roof
- DC and AC cables, connectors and earthing
- Lightning and surge protection
- ACDB/DCDB and isolation equipment
- Installation, testing and commissioning
- Net-metering or net-billing assistance
- Monitoring setup, warranties and after-sales support
A low quotation may exclude civil work, elevated structure, meter-related charges or long cable runs. Compare the complete scope, not only the price per watt.
On-Grid, Off-Grid and Hybrid Prices
An on-grid solar system is usually the most affordable option for reducing electricity bills. It works with the utility grid and normally switches off during a grid outage for safety.
An off-grid system includes batteries and is useful where power cuts are frequent or grid supply is unavailable. Batteries can substantially increase the initial cost and require eventual replacement.
A hybrid solar system combines grid connectivity with battery backup. It offers greater energy security but normally costs more than a comparable on-grid system.
How Much Can Solar Save in Siliguri?
A well-designed 3kW system can generate roughly 300–390 units in a typical month. If most energy is consumed or adjusted under the applicable billing mechanism, this can significantly reduce the electricity bill. The exact saving depends on the consumer’s tariff, daytime usage, sanctioned load and utility settlement rules.
For the best sizing, review at least 12 months of bills. Oversizing a plant without checking sanctioned load, roof area and export rules may weaken the return on investment.
Factors That Change Solar Panel Cost
- Panel technology: Mono PERC, TOPCon and bifacial modules differ in output, efficiency and cost.
- DCR requirement: Subsidy-linked residential installations may require domestically manufactured components as prescribed by the scheme.
- Roof type: RCC roofs, metal sheds, sloped roofs and elevated structures need different mounting solutions.
- Shade: Trees, tanks and neighbouring buildings can reduce generation or require layout changes.
- Inverter and protection: Reliable equipment and correct electrical protection improve safety and uptime.
- After-sales support: Local service, monitoring and warranty assistance have long-term value.

FAQs
What is the price of a 3kW solar system in Siliguri?
A 3kW on-grid system may cost approximately ₹1.65–₹2.10 lakh before subsidy. Eligible residential consumers may receive up to ₹78,000, subject to current scheme rules.
Is the subsidy deducted immediately?
Usually, the consumer follows the official application, installation, inspection and commissioning process. Subsidy is released after the prescribed approvals; it should not be assumed as an instant dealer discount.
How much roof area does 3kW solar need?
Plan roughly 250–350 sq. ft. of shadow-free area, although high-wattage modules and the roof layout can change the requirement.
Which solar system is best for power cuts?
An off-grid or hybrid system with adequate battery storage is more suitable. A standard on-grid inverter generally does not provide backup during a grid failure.
