YANTAI, China, September 23, 2026 - As municipalities and road authorities across the Middle East, Africa, Asia and Latin America move solar street lighting projects to tender this autumn, Suntisolar - a 16-year professional manufacturer of government-grade solar street lights - has published a complete specification checklist to help procurement teams evaluate bids against the six specifications that decide whether a public lighting project succeeds: wattage, lumens, IP rating, wind load, battery, and certification.
The guide, "How to Choose Solar Street Lights for Government Tenders: A Complete Specification Checklist," is now available on the company's website and links directly to the full product catalog, giving engineers and contractors a line-by-line reference for writing and verifying tender documents.
Background: A manufacturer stepping up as government demand grows
The release follows a string of recent milestones for the company. In September 2026 alone, Suntisolar showcased its self-cleaning solar street lights at Middle East Energy, entered mass production of its Z58 series high-efficiency smart solar street lights, and shipped a full 40HQ container of 100W all-in-one units to an export customer.
The company's government track record underpins the timing of the announcement:
- 6,000 units for a highway lighting project in Algeria
- 5,200 units for the DPWH solar street light project in the Philippines
- 1,000 units for urban road lighting in Saudi Arabia
"Government tenders are won and lost on specifications, not promises," said a Suntisolar spokesperson. "A bid can look identical on paper and still fail the illuminance test, rust in a coastal environment, or go dark after the first storm season. Our checklist is the document we wish every procurement team had before signing - it is the same standard we build to, with a <0.5% failure rate and a 5-year warranty."
The six checkpoints procurement teams should specify
The published guide walks tender teams through each specification with real, verifiable figures from the Suntisolar range:
1. Wattage (power output) - matched to road class and pole height, from 30 W village lights up to 240 W highway fixtures.
2. Lumens (light output) - emphasizing that lumens measure total light while lux measures light on the road surface, with a starting range table from 1,500 lm for walkways to 30,000+ lm for multi-lane highways (Suntisolar's 240 W unit delivers 30,000 lm at 12 hours full power).
3. IP & IK rating - specifying IP66 dust/water protection and IK08/IK09 impact resistance as the standard for unattended outdoor installation.
4. Wind load - rating the pole, not just the luminaire, with Q235/Q355 galvanized steel poles designed to withstand 206 km/h winds.
5. Battery - specifying LiFePO₄ chemistry for temperature resistance and cycle life, with capacity verified in Ah and Wh (up to a 25.6 V / 90 Ah battery on the flagship models).
6. Certification & documentation - requiring CE, RoHS, IEC, CB, SASO and ISO9001 certificates plus third-party test reports in the tender file.
