The solar light is composed of several parts: a solar cell module, some LED lamps, a control box (its control box contains the charger, controller, and battery), and a light pole. Solar panel luminous efficiency of 127Wp/m2, high efficiency, and the wind-resistant design of the system are very favorable. The lamp head part of the 1W white LED and 1W yellow LED integrated into the printed circuit board is arranged as some spacing of the dot matrix as a flat light source. The control box is made of stainless steel, which is beautiful and durable. The maintenance-free lead-acid battery is placed inside the control box, and the express charge controller for solar street lights is successfully developed by the patented technology of slow pulse fast charging and discharging. The system uses a valve-regulated sealed lead-acid battery, which is also called a “maintenance-free battery” because of its little maintenance, which is conducive to reducing system maintenance costs. The charge and discharge controller is designed to take into account functional readiness (with light control, time control, over-charge protection, over-discharge protection and reverse connection protection, etc.) and cost control to achieve a high-cost performance.
The solar light working principle is simple. Solar cells are made using the photovoltaic effect principle. Solar panels receive solar radiation energy during the day and convert it into electrical output, which is stored in the battery after charging and discharging the controller. At night, when the illumination gradually decreases to about 101ux, the solar panel open circuit voltage is about 4.5V, the charge and discharge controller detects this voltage value and then acts, and the battery discharges to the lamp head. After the battery is discharged for 8.5h, Charge and discharge control action, and the battery will be discharged. The primary role of the charge and discharge controller is to protect the battery.
Solar energy is the sun’s internal or surface of the continuous system of nuclear fusion reaction of the spirit generated by the nucleon. The average solar radiation intensity in the land’s orbit is 1367w/㎡. The standard peak intensity at sea level is 1kw/㎡, and the annual mean radiation intensity at a point on the land’s surface for 24h is 0.20kw/㎡, which is equivalent to 102,000 TW of energy. On which humans depend for their survival, This includes all other forms of renewable energy (except geothermal energy). Although the total amount of solar energy resources is equivalent to more than 10,000 times the energy used by human beings, the energy density of solar energy is low. And it varies from place to place and from time to time, which is the main problem facing the development and utilization of solar energy. These characteristics of solar energy can earn its role in the overall integrated energy system somewhat limited.
Although the energy radiated by the sun into the land’s atmosphere is only one 2.2 billionth of its total radiant energy, it has been as high as 173,000 TW, which means that the sun’s energy hitting the land every second is equivalent to 5 million tons of coal. The wind, water, ocean temperature difference, wave, and biomass energy, as well as some tidal energy on Clay, are all derived from the sun; even the land’s fossil fuels (such as coal, oil, natural gas, etc.) are fundamentally stored solar energy since ancient times, so the broad sense of solar energy includes a too most range while the narrow sense of solar energy is limited to the direct conversion of solar radiation energy photothermal, photoelectric and photochemical.
Solar energy (Solar Energy), generally referring to the radiation energy from the sun’s rays, is commonly used in modern times to generate electricity. Since the formation of the land, living organisms have lived mainly on the heat and light provided by the sun, and ancient humans also knew how to dry things in the sun as a man to preserve food, such as making salt and salting fish. But in the fossil fuel reduction, only then the intention to further develop solar energy. Solar energy is used in two ways: passive purpose (photothermal conversion) and photovoltaic conversion. Solar power is an emerging renewable energy source. Solar energy in a broad sense is the source of many of the land’s energy sources, such as wind energy, chemical energy, water potential energy, etc.
As the earth’s resources become increasingly impoverished, the cost of investing in first energy is climbing higher and higher, and various safety and pollution hazards are ubiquitous. In this way, solar lighting products should be born after the popularity of solar water heaters, where we make a practical comparison between the effects of solar lamps and the use of utility lighting.
* Contrast a utility lighting installation complex: In the utility lighting projected the are complex operating procedures, and first of all, to lay the cable, here we have to excavate the cable trench, lay concealed pipe, pipe threading, backfill, and a lot of basic engineering. Then a long period of installation and commissioning, such as any one line has a problem it is necessary to rework a large area. And the terrain and line requirements are complex, and labor and auxiliary materials are costly. Solar lighting is easy to install: When solar lighting is erective, there is no need to lay complicated lines, only make a cement base and then fix it with stainless steel screws.
* Contrast 2: Utility lighting fixtures have high electricity costs: Utility lighting fixtures work with fixed high electricity costs and require long-term uninterrupted maintenance or replacement of wiring and other configurations, with maintenance costs increasing year by year. Solar lighting fixtures are free of electricity: solar lighting fixtures are a one-time investment, with no maintenance costs, three years to recover the investment costs and long-term benefits.
* Contrast three: Municipal lighting has safety hazards: Municipal lighting brings many safety hazards due to the quality of construction, transformation of landscape lighting, aging materials, irregular power supply, and conflicts of water, electricity, and gas pipelines. Solar lighting has no safety hazards: solar lamps and lanterns are ultra-low voltage products, safe and reliable operation.
Other advantages of solar lighting: green and environmentally friendly. it can add new selling points for the development and promotion of noble ecological communities; it can sustainably reduce property management costs and shorten the spending of the owner’s public share. In summary, the inherent characteristics of solar lighting such as safety without hidden dangers, energy saving without consumption, green environmental protection, easy installation, automatic control, and maintenance-free will bring visible advantages for the sales of properties and construction of municipal projects directly.
