Solar energy – the energy of this century one of the major human.By 2030, the world’s electricity production will mainly rely on solar energy. Solar energy as a non-polluted environment, but also an inexhaustible supply of new energy will be everywhere. Solar photovoltaic products is through the effect of light under the sun, into electricity process, is a use of high-tech development of new energy, mankind yearns for the 21st century, the pursuit of new sources.
Solar lights and solar power generation systems and other products of the main innovations:
01 energy, which uses natural light, without consumption of energy, and inexhaustible not finish;
02 environmental protection, in line with environmental protection requirements, no pollution, no radiation, ecological protection;
03 security, the product does not use the AC, and the use of batteries to absorb solar energy, through the low-voltage direct current into light, is the most secure supply;
04 science and technology, the core product is the intelligent controller device, set the self-control, time control switch device 24 hours a day according to the sky brightness and people in a variety of environments need to automatically adjust the brightness;
05 long life, low cost installation and easy maintenance.
The company’s optoelectronic products, detected by the state and municipal departments and Cai Zuquan and other relevant experts, the product has reached international advanced level of similar products.
Advantages Solar lights
As the Earth’s resources become increasingly scarce, increasingly based on investment costs of energy rising, and a variety of safety and pollution problems can be described as ubiquitous. Solar energy as an “inexhaustible” security, environmental protection and new energy sources more and more attention. Thus, solar water heaters with solar lighting products came into being after the popular, solar lighting in here and use the city as a practical circuit the effect of light contrast.
A comparison:
Street lighting, installation of electricity complex: in the city, street lighting project has a complex operating procedures, the first laying of cables, cable channel will be carried out here, excavation, laying of underground pipe, pipe threading, backfill and other large infrastructure projects. Then a long period of installation and commissioning, if any of the lines in question, will have to rework large areas. And the requirements of complex terrain and line, the high cost of labor and supporting materials. Easy to install solar lights: solar street lighting installation, without the laying of a complex line, just do a cement base, and then you can use stainless steel screws.
Contrast II:
Mains electricity lighting the high street: street lighting, electricity work has a fixed high tariffs for long-term continuous and other configurations on the line for maintenance or replacement, maintenance costs every year. Solar Road lamp-free electricity: solar street lamp is a one-time investment, no maintenance costs, investment costs recovered for three years, long-term benefit.
Comparison three:
Street lighting, electricity has security risks: market power due to the construction quality of street lighting, landscape renovation project, materials aging, power supply not normal, water and electricity pipes and other aspects of the conflict brought a lot of security risks.
No safety hazards of solar lights: solar lighting is super low-voltage products, safe and reliable operation. Other advantages of solar lights: green for high ecological community in the development and promotion of the addition of new selling point; sustainable reduction of property management costs and reduce the cost of some of the owners of public sharing.
Described in the foregoing comparison, solar street safety without problems, no energy consumption, environmental protection, ease of installation, maintenance-free features such as automatic control, for the sale of real estate, municipal construction projects can be used directly to bring significant advantages.
Solar street light consists of the following components: solar cells, batteries, solar lighting special controller, light and lamp. Is an automatic control system of work, simply set the operating mode of the system will automatically work. Solar street lamp is ideal for road lighting, along with the improvement of people’s lives and society continues to develop, it will be widely used, so that the bright sun, the earth has given to mankind in the night lighting.
Principles of solar power
Solar power system consists of solar batteries, solar controller, battery (group). If the output power AC 220V or 110V, also need to configure inverter. The role of each part as follows:
(A) of solar panels: solar panel solar power system is a core part of the solar system is part of the highest value. Its role is to convert the sun’s radiation to electrical energy, stored in batteries or sent to, or promote the work load. Solar panels will directly determine the quality and cost of quality and cost of the system;
(B) Solar Controller: Solar controller’s role is to control the entire system state, and played a battery charge protection, over discharge protection. In the large temperature difference, the controller should have qualified temperature compensation function. Other additional features such as light-control switch, control switch when the controller should be optional;
(C) Battery: lead-acid batteries generally, small micro-systems, can also be used nickel metal hydride batteries, nickel cadmium batteries or lithium batteries. Its role is when there is light emitted by solar energy stored up, and then released when needed;
(D) inverter: In many occasions, will need to provide 220VAC, 110VAC AC power source. As a direct output of solar energy are generally 12VDC, 24VDC, 48VDC. In order to provide the 220VAC electrical power, solar power system needs to be issued by the DC energy into AC power, so need to use the DC-AC inverter. In some cases, you need to use a variety of voltage, load, also used DC-DC inverter, such as the electrical energy will be converted to 5VDC 24VDC of power (note, not a simple step-down)
