Solar Street Lights in India: Specifications, Schemes, Prices and Buying Tips
A guide to solar street lights in India: typical sizes for villages and towns, sun hours by region, MNRE-style specifications, government schemes, what drives price, and how to choose a supplier.
Key points
- India has strong sun in most regions, typically about 4.5–6 peak sun hours a day outside the monsoon, which suits solar street lights well.
- The monsoon is the design challenge: several cloudy days in a row mean batteries need 2–3 nights of autonomy.
- Government and panchayat projects usually follow MNRE-style technical specifications; check the current specification for the scheme you are bidding for.
- Compare products by panel Wp, battery Wh and chemistry, LED efficacy and warranty, not by the wattage printed on the box.
India is one of the largest markets for solar street lights. Villages, highways, industrial parks, campuses and housing societies use them where grid power is unreliable or connections are expensive. The strong sun helps; the monsoon is what designs must be built for.
Sun hours by region (approximate)
| Region | Typical peak sun hours (dry season) | Monsoon effect |
|---|---|---|
| Rajasthan, Gujarat | 5.5–6.5 | Short monsoon, strong sun |
| Maharashtra, Karnataka, Telangana | 5–6 | Heavy monsoon on the west coast |
| Tamil Nadu, Andhra Pradesh | 5–6 | Rain in the north-east monsoon season |
| Uttar Pradesh, Bihar | 4.5–5.5 | Hazy winters, monsoon |
| Kerala, Konkan coast | 4.5–5.5 | Long, heavy monsoon |
| North-east states | 4–5 | Long cloudy periods |

Typical configurations
| Application | LED | Pole | Typical setup |
|---|---|---|---|
| Village lanes, panchayats | 12–24 W | 4–6 m | All-in-one, lithium battery |
| Housing societies, campuses | 20–40 W | 5–7 m | All-in-one or semi-integrated |
| Town roads | 40–60 W | 7–8 m | Semi-integrated or split |
| Highways, industrial parks | 60–90 W | 8–10 m | Split system, larger battery |
Our all-in-one solar street lights cover 15–60 W on 3–8 m poles, and the split solar street light suits higher poles.
Specifications for government projects
Government and panchayat tenders usually follow technical specifications based on MNRE guidelines and state agency requirements. These typically define:
- LED power and minimum system efficacy
- Panel rating and type
- Battery chemistry (lithium-based in recent specifications), capacity and autonomy
- Charge controller type and protections
- Operating hours and dimming
- Pole height, material and coating
- Testing, certification and warranty periods
The exact figures change between schemes and years. Always work from the current tender document; our solar street light specification template shows how to structure one.
Schemes and funding
Solar street lighting has been supported through national programmes and state schemes, often implemented by state renewable energy development agencies, district administrations and gram panchayats, as well as through MPLAD and similar local development funds and CSR programmes. Eligibility, subsidy levels and procedures differ by state; check with your state agency before planning on a subsidy.
What drives price
| Item | Effect |
|---|---|
| Battery capacity and chemistry | Often the largest single cost |
| Panel Wp | Second largest |
| LED and driver quality | Efficiency and life |
| Pole and foundation | Height, thickness, galvanising |
| Installation and transport | Remote sites cost more |
| GST and warranty | Check current rates and terms |
| Quantity | Large orders reduce unit cost |
Our solar street light price guide explains each component’s share.
Choosing a supplier
- Ask for test reports for the exact model, including battery capacity and LED efficacy
- Check that panel and battery sizes match the claimed runtime with monsoon autonomy
- Insist on LiFePO4 batteries for heat tolerance and long life
- Look for IP65 or better and surge protection
- Check warranty terms and service network in your state
- Ask for references from similar projects
Whether you buy from an Indian brand, an integrator or an overseas manufacturer, the same checks apply.
Installation and maintenance
- Panels facing south at about the latitude angle (roughly 10–30° across India)
- Clear of trees, buildings and other lights
- Clean panels regularly in dusty regions, especially before the monsoon
- Check batteries and controllers yearly
- Plan battery replacement after about 5–8 years

Theft and vandalism
Panels and batteries are targets. All-in-one designs with batteries in the head, anti-theft bolts and community involvement reduce losses on village projects.
Smart and remote monitoring
Larger municipal projects increasingly ask for remote monitoring of battery and charging status, which helps maintenance teams act before lights go dark. See smart streetlights.
Common mistakes in Indian projects
Many problems seen on Indian sites come from the same few causes. Batteries sized for the dry season fail in the monsoon. Panels are mounted facing the road rather than south, or under trees that grow over a few seasons. Cheap lithium-ion cells degrade quickly in summer heat above 40 °C. And maintenance is not budgeted, so dusty panels and weak batteries leave villages dark within two years. Specifying LiFePO4 batteries, monsoon autonomy and a simple maintenance plan avoids most of these problems.
Village and panchayat projects
For gram panchayat projects, simplicity and theft resistance matter most. All-in-one lights on 5–6 m poles, with dimming after midnight and a two to three night battery, are the usual choice. Mark each pole with a number and keep a list with GPS positions so faults can be reported and found easily.
Highways and industrial parks
Highway and industrial park projects use higher poles, larger split systems and often remote monitoring. They also have stricter documentation: drawings, photometric calculations for the road class, test reports and maintenance plans. Plan these documents into the bid from the start.
Working with us
We supply solar street lights for importers, EPC contractors and project developers. For projects in India, send us the location, road types, hours of operation and the specification you need to meet, and we will propose configurations with an energy balance for the monsoon months.

Frequently asked questions
What size solar street light is used in Indian villages?
Village roads and panchayat projects typically use all-in-one or semi-integrated lights of about 12–40 W LED on 4–7 m poles, with lithium batteries. Main roads in towns use 40–90 W on 7–9 m poles.
What is the price of a solar street light in India?
Prices vary widely with LED power, panel and battery size, pole, brand and quantity, and with GST and installation. Compare offers on the same specification, including battery capacity and warranty, rather than on wattage alone.
Are solar street lights subsidised in India?
There have been national and state programmes supporting solar street lighting, often implemented through state nodal agencies and panchayats. Eligibility and rates change, so check with the state renewable energy agency for current schemes.
