1.1.3 solar cell current position in the field of road lighting
In addition to people's pursuit of environmental protection, the ability to light street lamps and solar cells provide electrical power requirements determines the current status of solar lighting in the area. If we design, "city road lighting design standards" in the ¡éñ, ¡é¨° type of road lamps, since the electricity in daily 3-4.8KWH, solar power needs to reach more than 1KW. Let us not consider the cost of 1KW solar cells, only on solar cell design work area will make it difficult to carry out. Currently, the solar cell area of ??120W / square meter, the solar cell area of ??about nine square meters 1KW, such a large area is almost impossible in the like rod fixed. Further, in order to meet the city in terms of continuous rainy days to work, but also to expand the capacity of the battery several times, it also requires a lot of battery box.

However, there are many manufacturers of solar lights do not agree with the above conclusion. They think that ordinary street using low-efficiency light source, as long as the light changed to energy-saving lamps or LED light source can be with a small electric power reached the national standards required illuminance, or by changing the method of optical design, with a small you can get a high flux of illuminance, so with a small solar power solar lights can be done successfully. This view is clearly defective, illuminance is the luminous flux per unit area, how could there be no flux illumination? To say the least, if there is such a possibility, street lighting is long overdue that a source of innovation. Also the market LED luminous efficiency is still much lower than the conventional sodium or metal halide lamp, or even more than capable and energy-saving lamps.
Identified in the above analysis, we believe that solar lighting in the area is currently only suitable for manufacturing "city road lighting design standards" in the branch and for pedestrians and non-motorized traffic in the residential area roads and sidewalks street, that is, we usually say street lights and garden lights. Sub-distributors lights do very reluctantly.
2 local conditions install solar street city
As there is no pollution of solar green energy, very suitable for use in road lighting, particularly areas without power or laying power lines difficult places.
Currently plaguing solar street in one of the major urban development is positioning error, blindly using the main roads in the road of urban roads, downtown or commercial center, major transport hubs and other locations, with the result that despite efforts, Since solar energy can offer is not yet able to meet the fast road, trunk road and Welcome Road illumination requirements, application of sola

12V200Ah Solar Battery Deep Cycle

$1 - $204.70
MOQ: Not Specified
 
12V200AH solar battery deep cycle is maintenance free
Fully use the internal space of battery to increase the capacity of battery without changing the volume of battery .This is to say, users may have a large output power and capacity of battery after choosing the proper capacity of battery .We offer them the most economical products.

Long service life
As high quality multiple alloy electrode plate and unique electrolysis are adopted, the service life floating battery under normal temperature mach over 3 years and the service life of floating battery under 20;C may reach 5 to 10 years.

Low self-discharge speed
the unique electrolysis makes the battery usable directly without recharging after storage of six months under normal temperature and one year fewer than 20;C.

Deep discharge protecting
the battery may be recharged within 30 days when being deeply discharged or any fault occurs to the machine.

All-sealed & maintenance-free
No maintenance is required during the whole operation period. All pores of the cell are closed to avoid the incoming of oxygen in the air. The safe valve on the pore will be opened automatically to release the internal pressure after being over charged, and be closed again.

Explosion-proof design
a safety valve and a special filter prevent the chance of battery explosion and ensure complete safety in normal use.

Application scope
Alarm system, emergent illuminations system, post and telecommunication electronic system, UPS and computer back-up power source, fire-fighting and safeguard system, medical equipment, solar system ,shipping equipment ,control equipment ,and environmental electric bicycle, etc.
