9W to 80W Solar Street Lights

As the demand for eco-friendly and cost-effective lighting solutions grows, solar street lights have become an essential choice for urban and rural areas. Sinesan Technologies Pvt. Ltd., a leading manufacturer of solar street lights and accessories, offers a wide range of options, from 9W to 80W models.

But how do you determine the right wattage for your needs? Whether you're illuminating a small garden, a residential street, or a busy highway, understanding the differences between low-wattage and high-wattage solar lights is crucial.

In this guide, we'll break down the power ratings, usage scenarios, benefits, and key factors to consider when choosing the best solar streetlight for your needs.

Understanding Solar Street Light Wattage

What Does Wattage Indicate?

Wattage (W) in solar street lights refers to the power consumption of the LED light source. It directly affects:

• Brightness (Lumens Output): Higher wattage = Brighter light.
• Coverage Area: Higher wattage = Wider illumination range.
• Battery Consumption: Higher wattage = Higher energy consumption.

Low-Wattage vs. High-Wattage Solar Street Lights

• Low-wattage lights (9W - 20W): Suitable for small streets, home driveways, and pathways.
• Medium-wattage lights (25W - 40W): Ideal for residential areas, parks, and parking spaces.
• High-wattage lights (50W - 80W): Best for highways, large public areas, and industrial spaces.

Detailed Comparison: 9W to 80W Solar Street Lights

Wattage	Recommended Use	Lighting Coverage	Backup Time	Best Suited For
9W - 20W	Small streets, gardens, pathways	10-20 meters	8-12 hours	Home driveways, village roads, pathways
25W - 40W	Medium streets, parks, parking areas	20-30 meters	10-14 hours	Residential streets, school campuses
50W - 60W	Large streets, commercial spaces	30-50 meters	12-16 hours	Highways, industrial parks, public areas
70W - 80W	Highways, urban roads, large spaces	50-70 meters	12-16 hours	High-traffic roads, stadiums, large campuses

Factors to Consider When Choosing a Solar Street Light

1. Brightness & Lumens Output

• 9W – 20W: Produces 1000 – 2500 lumens (best for gardens, home pathways).
• 25W – 40W: Produces 3000 – 6000 lumens (suitable for residential streets, parks).
• 50W – 80W: Produces 7000 – 12000 lumens (ideal for highways, large open areas).

2. Battery Capacity & Backup Time

• A good solar street-light should provide at least 8-16 hours of backup.
• LiFePO4 (Lithium Iron Phosphate) and Lithium-ion batteries offer longer life and faster charging.

3. Solar Panel Efficiency

• Monocrystalline solar panels are highly efficient and convert sunlight into electricity faster.
• Ensure the panel size is sufficient to charge the battery even on cloudy days.

4. Installation Height & Coverage Area

• 9W-20W: Install at 3-4 meters height for small streets and pathways.
• 25W-40W: Install at 4-6 meters height for residential roads and parks.
• 50W-80W: Install at 6-10 meters height for highways and large commercial areas.

5. Material & Durability

• Aluminum alloy & weatherproof (IP65/IP67) designs enhance durability.
• Ensure the solar light is dustproof, waterproof, and rust-resistant for long-term performance.
