Because of short of public electricity source or inconvenient or not economic, now more and more markets need solar power lights, such as highway or freeway, city streets, country roads, islands, villages far away from cities, etc. , the solar energy lights can work working automatically, don’t need to make big investment for public electricity line and constructions, free maintenance, suitable for most of the markets where there are sunshine only ( or wind power).
Energy source: solar power or wind power Working time: 4-12 hours Pole height: 2-12m Pole structure: Single arm / Double arms / 4 arms Lamp type: LED / LPS System warranty time: 1-3 years (based on the quality components required).
Questions before the system designing:
1. Where to install the systems, the latitude and longitude of the markets.
2. Lamp capacity, how many watt lamps ( 20W – 120W)
3. Daily working time, how many hours to work everyday, 3-12hours
4. Height of the pole system, height of the lamp, pole structure, single arm type or double arms type or 4 arms type ?
5. Max how many rainy days to take averagely ?
6. What quality system do you need ? High quality or economic quality systems ?
7. Any other relative technical requirements or data.
Based on the replies of the above questions, then we can work out the capacity of the solar panels, batteries and easy for us to make the design of the systems, more reasonable and economic according to the tender.
