Solar Panel Installation in Siliguri: A Practical Guide

North Bengal gets fewer clear-sky days than Rajasthan or Gujarat, and homeowners often assume solar therefore does not pay here. In practice Siliguri averages enough usable sunlight through the year that a well-sized rooftop system still recovers its cost — provided the design accounts for the monsoon rather than ignoring it.

The roof survey comes first

We look at usable shadow-free area, roof orientation, structural condition and cable routing to the meter. A south-facing slope is ideal, but flat RCC roofs work perfectly with tilted mounting frames — the standard in most Siliguri houses.

Sizing your system

• 1 kW — roughly 4 units a day, suits a small flat with lights, fans and a TV
• 3 kW — the common family choice, covers most of a 3 BHK bill including a fridge
• 5 kW and above — larger homes with air conditioning, or small shops and offices

On-grid, off-grid or hybrid?

On-grid gives the fastest payback but shuts down during a power cut. Off-grid runs on batteries and keeps working through outages. For most Siliguri homes a hybrid system is the sensible middle path: you export surplus during the day and still keep essential circuits alive when the supply drops.

How long installation takes

A typical residential installation runs two to four days on site once material arrives — mounting structure, panel fixing, inverter and wiring, then earthing and testing. Grid connection paperwork usually takes longer than the physical work, so start the application early.
