1.The system matches the questions.
Nowadays, manufacturers of solar lamps and lanterns often pursue too much modeling design, and ignore the most important system matching design, without in-depth consideration, simple calculations, and finally lead to a large number of problems in lamps and lanterns; There are also some manufacturers in order to create the best advantage of their own products, at the expense of the system is not chaotic, these practices are undesirable.
Matching design is an important factor related to the reliability and non-chaos of the system, and the following aspects should be considered in order to cause serious attention:
1) The ratio of solar cell power generation to load power consumption is fair.
2) The ratio of power consumption and battery capacity should meet the requirements of continuous rainy days and the discharge depth should be fair.
3) The ratio of solar cell charging current and battery capacity is fair.
4) The load discharge current is reasonably proportioned to the battery capacity.

Today's solar street lights are mainly lead-acid batteries, and the conventional service life is 2-3 years. However, gel batteries are also used, and the service life of gel batteries is 8-10 years.
Gel battery belongs to a development classification of lead-acid battery, the simplest way is to add a gelling agent to sulfuric acid to make the sulfuric acid electro-hydraulic into a colloidal state. Batteries with gelatinous electrohydraulics are often referred to as gel batteries.
Broadly speaking, the difference between gel batteries and conventional lead-acid batteries is not only that the electro-hydraulic is changed to gelling. For example, non-condensate water-based colloids belong to the same colloidal battery in terms of electrochemical classification, structure and characteristics. Another example is the attachment of polymer materials in the grid, commonly known as ceramic grids, which can also be regarded as the application characteristics of gel batteries.
Recently, a laboratory has added a targeted coupling agent to the plate formulation, which greatly improves the reaction utilization rate of the plate active material, and according to non-public information, it can reach a weight specific energy level of 70Wh kg, which is an example of the current industrial practice and the application of gel batteries to be industrialized.
The difference between gel battery and conventional lead-acid battery has been further developed from the initial understanding of electrolyte gelling to the study of the electrochemical properties of the electrolyte basic structure, as well as the application and promotion in grid and active materials. Its most important features are: with a small industrial cost, along the 150-year-old lead-acid battery industry to create a better quality battery, its discharge curve is straight, the inflection point is high, the specific energy is especially the specific power is more than 20% larger than the conventional lead-acid battery, the life is generally about twice as long as the conventional lead-acid battery, and the high and low temperature characteristics are much better.
Performance and characteristics of gel battery: sealed structure, electro-hydraulic gel, no leakage; Charging and discharging without acid mist and pollution, it is an environmentally friendly product vigorously promoted and applied by the state; High capacity, 10-20% increase capacity compared with lead-acid batteries of the same level; Strong charging and receiving ability; Small self-discharge, storage resistance; The over-discharge recovery performance is good, and the high-current discharge capacity is more than 30% higher than that of lead-acid batteries; Good low temperature performance, meet the requirements of -30 to -50 starting current; Stable high-temperature characteristics, meeting the requirements of 65 or even higher temperature environments; The cycle service life is long, which can reach 800-1500 times of charging and discharging; The industrial cost per unit capacity is lower than that of lead-acid batteries, and the economic benefits are high.

Solar lawn light is a kind of green energy lamp, which has the characteristics of safety, energy saving, environmental protection, and easy installation. Solar lawn lights are mainly composed of light sources, controllers, batteries, solar cell modules and lamp bodies. Under light irradiation, it stores electrical energy in the battery through the solar cell, and in the absence of light, the battery electric energy is fed into the load LED through the controller.
It is suitable for residential community green grass landscaping, lighting decoration, park lawn landscaping, and decoration.
System composition: A complete solar lawn light system includes: light source, controller, battery, solar cell module and lamp body.
When sunlight hits a solar cell during the day, the solar cell converts the light energy into electricity and stores the electrical energy in the battery through a control circuit. After dark, the electrical energy in the battery is supplied with power to the LED light source of the lawn light through a control circuit. At dawn the next morning, the battery stops powering the light source, the lawn lights go out, and the solar cells continue to charge the battery, repeating the cycle.
The controller is composed of a single-chip microcomputer and a sensor, which controls the opening and closing of the light source part through the acquisition and judgment of the optical signal. The lamp body mainly plays the role of system protection and daytime decoration to ensure the normal operation of the system. Among them, the light source, controller, and battery are the key to determine the performance of the lawn light system.
Solar lawn light is the project that consumes the most solar cells every year in China's solar photovoltaic application field, and is the only solar cell application product in the world controlled by special integrated circuits. It is expected that with the recovery of the global economy in the future, the total international market demand will increase, and the domestic market demand will gradually appear, and villas, parks, golf courses and other places may be the places with the most market demand.

The working principle of solar lawn light: circuit structure: the so-called photosensitive battery as a photosensitive device refers to the use of the light sensing characteristics of the solar cell itself, that is, the output voltage of the solar energy battery is buried in the optical sun, and the output terminal presents a high level; When there is no light, the solar cell has no voltage output, and the output appears low.
The circuit is mainly composed of battery charging circuit imitation, switching circuit and driving circuit. The charging circuit is composed of solar V1, diode D1 and battery V2; The switching circuit is composed of a triode Q1 and a resistor R2; The drive circuit consists of a triode Q2.
The working principle of the circuit: when there is light, it is equivalent to the switch S1 is closed, and 6 points are connected. At this time, the base of the triode Q1 has a high potential, the Q1 triode is on (the collector and the emitter are on), the Q1 triode is equipped with a tank nucleus in the saturation region, and the current through the R2 resistance will all be grounded to the emitter through the collector of the Q1 triode, and the current flowing to the base of the Q2 triode is almost zero, so the Q2 triode is cut off, that is, the collector and emitter of Q2 have no current, and the load LED1 has no current and stops working.
At the same time, the electric energy generated by the solar cell is charged to the battery V2 through one part of the D1 diode, and the other part is grounded through the R2 resistor, Q1 collector, and Q1 emitter. Since the internal resistance of the battery is much smaller than the R2 resistance, the electrical energy generated by the solar cell flows almost to the battery V2.
When there is no light, it is equivalent to switch S1 is disconnected. At this time, the base of the triode Q1 appears at a low point, the Q1 triode cut-off (collector and emitter cut-off), the Q1 triode is in the cut-off area, and the current through the R2 resistance will all be grounded to the emitter through the base of the Q2 triode, so the Q1 triode is in the amplification area, that is, the base current and the collector current of Q1 are multiplied, and the load LED1 works normally.
