problems of solar module

Solar Panel as an “inexhaustible” security, environmental protection and new energy sources more and more attention. In this way, solar lighting products emerged as the popularity of solar water heaters, solar lamps in here and use electricity for lighting the practical effect of contrast.

As the Earth’s resources become increasingly scarce, the cost of increasing investment in basic energy of the rising, and a variety of safety and pollution problems of solar module can be described as ubiquitous. After some comparison we find the following: solar lighting safety without risk, no energy consumption, environmental protection, ease of installation, maintenance and other characteristics of automatic control, for real estate sales, construction of public works to bring significant direct effect.

Comparing one city to install complex electrical lighting: lighting projects in the city in a complex operating procedures, the first laying of cable, where the cable trench excavation will be carried out, the laying of underground pipe, pipe threading, backfill and other large infrastructure projects. Then the long installation, such as a line with any problems, will have to rework a large area. And complex terrain and line requirements, the high cost of labor and auxiliary materials.

Comparison of the three cities have electric lighting safety hazards: electricity lighting due to the quality of construction, the transformation of the landscape works, materials aging, power supply is not normal, water and electricity pipes and other aspects of the conflict brought many security risks.

Solar Modules is no security risk: Solar lighting products are ultra-low voltage, safe and reliable operation. Other advantages of solar lighting: green, high ecological community for the development and promotion of the addition of new selling point; sustainable reduction of property management costs, reduce some of the owners share the cost of the public.

Easy to install solar lights: solar lighting installation, without laying a complex line, just do a cement base, then you can use stainless steel screws.

Solar street light consists of the following components: solar panels, solar controller, battery, light source, light poles and lamp housing. If the output power to 220V AC or 110V, but also configure the inverter.

Height of poles should be based on the width of the road, lighting the space, the road illumination standard-setting. Lamp housing according to our collection of sun light a number of foreign materials between the aesthetic and energy saving, most of them choose energy-efficient, less demanding exterior lighting, the relative utility on the line.

Solar panels and solar lights in the central part of the solar lights in the highest value. Its role is to the sun’s radiation is converted to electrical energy, stored in batteries or sent. Among the many solar cells in general and more practical than a single crystal silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cells, three. Sunny sunshine too good in the east and west, the use of polycrystalline silicon solar cells as well as polycrystalline silicon solar cell production process is relatively simple, lower price than the single crystal. More rainy days in the sun is relatively not very abundant in the southern region, using single crystal silicon solar cells as well as single crystal silicon solar cell performance parameters more stable. Amorphous silicon solar cells in the absence of sufficient sunlight outside is better, because the amorphous silicon solar cells on solar illumination conditions require relatively low.

Solar street lamp solar light in what is an important indicator of normal use, the general energy-saving lamps solar lamps use low pressure, low pressure sodium lamp, lamp, DLED light. Low energy-saving lamps: power is small, light-efficient, but the service life of 2,000 hours, low voltage lamp black, generally suitable for solar lawn lights, garden lights. Low-pressure sodium lamp: high efficiency low pressure sodium lights, but the need inverter, low pressure sodium expensive, making the entire system is high, use less. Lamp: power is small, light-efficient. The lamp in 220V (pure sine wave, frequency 50 Hz) under normal conditions of use of electricity, life can be up to 50,000 hours, life in the Solar Modules light on energy-saving lamps greatly reduced and almost ordinary. LED light source, long life, up to 1 million hours, low voltage, no inverter, light-efficient, made ​​50 Lm / w, imports of 80 Lm / w. As technology advances, LED performance will be further enhanced. I believe that the LED light source as solar street light will be a trend.

As the Earth’s resources become increasingly scarce, the basic rising cost of energy to increase investment, and a variety of safety and pollution hazards everywhere, solar energy as an “inexhaustible” security, environmental protection and new energy more and more attention. In addition, the development of solar photovoltaic technology and advances in green energy, LED Street Lights，solar energy street lamp, grass and other dual advantages of solar lighting products, applications development has gradually scale, solar lights, have become increasingly sophisticated. I want a peer reference design for solar lights bit.

According to “city road lighting design standards” requirement: the average fast road illumination 20lx, uniformity of 0.4, the average trunk road illumination 15lx, uniformity of 0.35, sub-distributors average intensity 8lx, uniformity of 0.35, the average slip illumination 5lx, uniformity 0.3. LED Street Light are in use, due to technical conditions, LED power small 30 ~ 100w, luminous efficiency 50 ~ 80lx / w, road illumination is low, I did the test, pole 8.5 meters high, spacing of 30 meters, the light source 2 × 50wLED light, lamp illumination 19lx, between two lights 11lx, most dark 3.5lx.

Number above the initial installation of lighting for the new illumination value, so the illumination is not satisfied with the trunk road expressway. Solar street lights should be in sub-distributors, with support on the road, the main road with caution.

LED lights daily working hours should work with the general requirements of street design should consider the short duration of sunshine in winter, their working time should be over in 12 hours. As the LED light influenced by the weather, rainy days in case of continuous lack of power and the LED lights can not be used. Countries are not normative for the LED lights in the low irradiance (continuous rainy days) case, allowing a minimum working time does not make provision, lighting manufacturers and are generally based on local meteorological conditions, should be in the low irradiance (continuous rainy days) working conditions work in 15 to 20 days. Should be fully considered in the design of solar panels and battery capacity.
