Are solar street lights covered under PM Surya Ghar subsidy?

No. PM Surya Ghar: Muft Bijli Yojana is only for residential rooftop solar. Street lights are not covered. Village street lighting is usually funded through separate government tenders, state programmes or CSR.

How many watts do I need for a home solar street light?

For a gate or compound, a 12W–30W all-in-one light on a 3–4 m pole is usually enough. Go higher only for wider areas or taller poles.

Is LiFePO4 better than a lead-acid battery in solar street lights?

Yes, for most buyers. LiFePO4 (LFP) lasts far more charge cycles, handles India's heat better and holds output longer, so it usually costs less per year despite a higher upfront price.

What is the difference between all-in-one and split solar street lights?

All-in-one packs the panel, battery, LED and controller into one unit that's easy to install. Split keeps parts separate for higher capacity and easier servicing, better suited to tall poles and main roads.

How much does a solar street light cost in India in 2026?

Indicative 2026 ranges (verify current): 20W around ₹2,500–₹6,000, 30–40W ₹4,000–₹9,000, 50–60W ₹6,000–₹14,000, and 100W+ ₹12,000–₹28,000, varying by brand, battery and type.

How far apart should solar street light poles be placed?

As a thumb rule, keep poles roughly 2.5 to 3 times the pole height apart so the light overlaps and you avoid dark patches. Taller poles with higher wattage can be spaced further.

Solar Street Lights India 2026: Price by Wattage Guide

Solar street lights have quietly become the easiest way to light up a gate, a society lane or a village chowk — no trench for wiring, no monthly electricity bill, and no drama during a power cut. But walk into any market or open a shopping site and the choices explode: 20W or 60W? All-in-one or split? Lithium or lead-acid? This guide keeps it simple and honest, so you buy once and buy right.

Quick answer: which solar street light do you need?

Match the light to the place, not to the biggest wattage on the box.

Home gate, compound or garden: a 12W–30W all-in-one light on a 3–4 m pole or wall bracket. Bright enough, tidy, easy to fit.
Society internal roads, parking, parks: 30W–60W, all-in-one or split, on 4–6 m poles.
Gram panchayat main street or chowk: 60W–100W+ split or high-capacity units on 6–8 m poles, usually bought in bulk tenders.

All-in-one vs split solar street lights

This is the first real decision. An all-in-one unit packs the panel, battery, LED and controller into one slim body that sits on top of the pole. A split system keeps the solar panel, the luminaire and the battery as separate parts, wired together.

Feature	All-in-one (integrated)	Split (two-part)
Install effort	Very easy, one unit	More work, separate mounting
Best for	Homes, lanes, compounds	Main roads, tall poles, villages
Typical pole height	3–5 m	5–8 m+
Battery capacity	Smaller	Larger, longer backup
Servicing / battery swap	Harder (sealed)	Easier (accessible box)
Cost	Lower	Higher
Monsoon backup	Modest	Better (bigger battery)

All-in-one (integrated)

Great for homes and societies. You lift it onto the pole, tighten a few bolts and you’re done. The trade-off: the battery is built in, so when it ages, replacement can be fiddly. Buy from a brand with local service.

Split systems

Better when you need serious brightness on a tall pole, or long backup through cloudy monsoon weeks. The battery usually sits in a lockable box on the pole or underground, so it’s easy to inspect and replace. More money, more install effort — but longer service life for busy roads.

Solar street light price by wattage (indicative 2026)

Prices swing a lot by brand, battery type, controller and whether it’s all-in-one or split. Treat the table below as a starting range only — indicative 2026, verify current with local sellers.

Wattage	Typical use	Indicative price range (2026 — verify current)
20W	Home gate, narrow lane	₹2,500 – ₹6,000
30–40W	Compound, society lane	₹4,000 – ₹9,000
50–60W	Society road, parking	₹6,000 – ₹14,000
100W+	Main road, gram panchayat street	₹12,000 – ₹28,000

One honest point: the PM Surya Ghar: Muft Bijli Yojana subsidy is only for residential rooftop solar — it does not cover street lights. Village street lights are usually funded through separate government tenders, state programmes or CSR, not the rooftop scheme. Don’t let a seller tell you otherwise.

Why LiFePO4 batteries matter

The battery decides how long your light lasts — both each night and over the years. Two common types:

Lead-acid (tubular/AGM): cheaper upfront, but fewer charge cycles and it fades faster in India’s heat.
LiFePO4 (LFP lithium): costs more, but survives far more charge cycles, handles heat better and holds output for years. As a rule, lithium batteries give longer life than tubular cells.

For anything you don’t want to climb up and service every season, insist on LiFePO4. Over 5–7 years it usually works out cheaper per year of light.

Lumens and pole height: getting the brightness right

Watts tell you power draw; lumens tell you actual brightness. Good LEDs give roughly 100–130 lumens per watt, so a 20W light throws around 2,000+ lumens and a 60W unit several thousand. Ask the seller for the lumen figure, not just watts.

Rough guide for pole height and spacing:

3–4 m pole: 12W–20W — home gates, narrow lanes.
4–5 m pole: 30W–50W — society roads, parking.
6–8 m pole: 60W–100W+ — main streets, village chowks.
Spacing: as a thumb rule, keep poles roughly 2.5–3 times the pole height apart so light overlaps and there are no dark patches.

Also check the IP rating — go for IP65 or higher so rain and dust don’t kill the electronics. A dusk-to-dawn sensor plus a motion sensor (dims when empty, brightens when someone passes) stretches the battery and helps it survive cloudy monsoon nights.

Use cases

Homes

A single 12W–30W all-in-one on the gate, plus one in the garden, is usually enough. Wall-mount or a short pole, LiFePO4 battery, motion sensor. Clean look, zero wiring, no bill.

Housing societies (RWA)

Internal roads, parking and parks do well with 30W–60W units on 4–6 m poles. If your roads are wide or you want strong monsoon backup, consider split units. Buying a set together often gets you a better rate — it’s worth getting 3 free quotes before the RWA signs off.

Gram panchayats and villages

Main streets and chowks need 40W–100W+ on 6–8 m poles, often split systems for serviceability. These usually go through bulk tenders, so ask for LiFePO4 batteries, IP66, and a clear warranty for each part before ordering in quantity.

How to choose: a simple checklist

Where is it going — pole height and road width decide the wattage.
Lumens — ask for the number, not just watts.
Battery — insist on LiFePO4 for long life.
Backup — aim for 2–3 cloudy nights of autonomy.
Controller — MPPT charging, motion sensor, dusk-to-dawn.
IP65 or higher for weatherproofing.
Warranty — separate cover for panel, battery and luminaire.
Brand and local service — matters more than a rock-bottom price.

A quick word on cost and quotes

Cheap lights that die in one monsoon are the most expensive lights of all. Before you buy — whether one unit for your gate or fifty for a village — get 3 free quotes, compare LiFePO4 vs lead-acid clearly, and read each warranty line.
