JDSOLAR solar garden light product structure
JDSOLAR solar garden light solar panel
The main function of solar panels is to convert light energy into electrical energy. This phenomenon is called the photovoltaic effect. Among the many solar cells, the most common and practical ones are mainly monocrystalline silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cells. In the east and west regions where there is enough sunlight, it is better to use polycrystalline silicon solar cells. Because the production process of polycrystalline silicon solar cells is relatively simple, the price is lower than that of monocrystalline silicon cells, and the conversion efficiency has also continuously improved in recent years. In the southern region where there are more rainy days and relatively less sunshine, it is better to use monocrystalline silicon solar cells, because the electrical performance parameters of monocrystalline silicon solar cells are relatively stable. Amorphous silicon solar cells are better when the indoor sunlight is very weak, because amorphous silicon solar cells have lower requirements for sunlight conditions.There are five major electrical performance parameters of solar cells:
1. Isc is short circuit current
2. Im is the peak current
3, Voc is the open circuit voltage
4. Vm is the peak voltage
5, Pm is the peak power
Note: Pm is the peak power = Im is the peak current × Vm is the peak voltage.
For a monolithic solar cell, it is a PN junction. It has all the characteristics of a PN junction except that it can generate electrical energy when sunlight is shining on it. Under standard lighting conditions, its rated output voltage is 0.48V. The solar cell components used in solar lighting fixtures are composed of multiple solar cell connections.
JDSOLAR Solar Garden Light Solar Charge Controller
Regardless of the size of solar lamps, a good performance charge and discharge control circuit is essential. In order to prolong the service life of the battery, its charge and discharge conditions must be limited to prevent the battery from overcharging and deep discharge. In addition, because the input energy of the solar photovoltaic power generation system is extremely unstable, the control of the battery charging in the photovoltaic power generation system is more complicated than the control of the ordinary battery charging. For the design of solar lamps, success and failure often depend on the success and failure of the charge and discharge control circuit. Without a charge-discharge control circuit with good performance, it is impossible to have a solar lamp with good performance. The charge and discharge controller must have the following characteristics:
1. Anti-reverse charge control
2. Anti-overcharge control
3. Anti-overdischarge control
4. Temperature compensation
JDSOLAR solar garden light solar energy storage battery
Because the input energy of the solar photovoltaic power generation system is not stable, it is generally necessary to configure the battery system to work, and the solar lamps are no exception. The battery must be configured to work. Generally, there are lead-acid batteries, Ni-Cd batteries, and Ni-H batteries, and their capacity selection directly affects system reliability and system price. The selection of battery capacity generally follows the following principles: first of all, under the premise of being able to meet the night lighting, the energy of the solar cell modules during the day is stored as much as possible, and at the same time, it can also store the electric energy that meets the needs of continuous rainy days and night lighting. The battery capacity is too small to meet the needs of night lighting or continuous use; the battery capacity is too large, the battery board can not provide enough charging current, the battery is often in a state of power loss, affecting the battery life and causing waste.JDSOLAR solar garden light load
Solar lighting products have the advantages of energy saving and environmental protection. Of course, the load must be energy-saving and have a long life. We generally use LED lamps, 12V DC energy-saving lamps and low-pressure sodium lamps.
Most lawn lamps use LED as the light source. The LED has a long service life, which can reach more than 100,000 hours, and the working voltage is low. It is very suitable for application in solar lawn lamps.
Garden lamps generally use LED lamps or 12V DC energy-saving lamps. The voltage of DC energy-saving lamps is DC, without inverter, which is convenient and safe.
Street lamps generally use 12V DC energy-saving lamps and low-pressure sodium lamps. Low-pressure sodium lamps have high efficiency but are more expensive and less used.
LED lamp housing
Between aesthetics and energy saving, most choose energy saving. The appearance requirements of lamps and lanterns should not be very high, it is relatively practical.
In summary, when choosing the solar garden light that suits you, in addition to the energy-saving and environmental protection characteristics of the product itself, it is also important to consider the stability of the product and the economy of the product.
