  • PV module-a power generation device
    PV module-a power generation device 2018-08-02

    The PV module is a power generation device that is exposed to direct currentin the sun.It consists of almost all solid state photovoltaic cells made of semiconductor materials (such as silicon). Simple photovoltaic cells can provide energy for watches and computers, and more complex photovoltaic systems can provide lighting and traffic lights and monitoring systems for houses, and integrate them into power grid. Photovoltaic panel components can be made into different shapes, and the components can be connected to produce more electrical energy. Photovoltaic panels can be used on rooftops and building surfaces, and even used as part of windows, skylights or shelter devices. These photovoltaic facilities are usually referred to as photovoltaic systems attached to buildings.

  • How to choose solar street light controller
    How to choose solar street light controller 2018-08-02

    The main control part of the solar street light is the controller, belonging to the "central nervous system" of the solar street light, controlling the charging and discharging of the solar street light, the battery overshoot protection, and the protection of the solar street light system as a whole. So how to choose solar street light controller? 1.choose the right current The current of the solar street lamp is 5A, 10A, 15A, 20A, etc. The current of the selected controller must be correct, and the selected current should be larger than the maximum current needed. For example, if the system current is 2A or 3A, we can choose 5A current. The maximum current is 5A, we can not only choose 5A current, the best choice 10A, to prevent the current is too large and burn the controller. the correct buck and boost features If the controller has step-down or step-up function, we have to choose the right one, and set the solar street light manufacturers before leaving the factory. 3.choose the right voltage Solar street lamp system voltage is 12 volts or 24 volts, but also a small part of the 36 volts and 48 volts, solar street light controller selection, we must choose the right voltage, or can not work. 4.electricity complementary controller and scenery complementary controller Electricity complementary controller and wind solar controller need to choose correct the electricity complementary voltage and fan voltage. 5.sub-time adjustment of the power controller, the choice of matching constant current source If you want street lighting to achieve sub-time control of brightness, you must select the matching of the constant current source, or impossible, different street controller on the constant current control requirements are not the same, so we must choose the right model .

  • Building Integrated PV
    Building Integrated PV 2018-08-02

    According to the investigation report of the United Nations Energy Agency, photovoltaic building integration will become the market hot spot of urban building energy efficiency in twenty-first Century. Solar energy construction industry will be one of the most important emerging industries in twenty-first Century. BIPV, Building Integrated PV, is the integration of photovoltaic architecture. PV is Photovoltaic. BIPV technology is a technology that integrates solar power (photovoltaic) products into buildings. Photovoltaic Architecture - BIPV is different from the form of the photovoltaic system attached to the building (BAPV:Building Attached PV). In the modern society, people's pursuit of the comfortable building environment is getting higher and higher, which leads to the increasing energy consumption of building heating and air conditioning. In developed countries, building energy has already accounted for 30% - 40% of the total energy consumption of the country, which has formed a certain restriction on the economic development. The combination of solar energy with the building envelope, the installation of solar power on the surface of the device in the building structure to provide power, can not only expand the production of clean energy, and does not occupy the city ground space, has been adopted by more and more countries.

  • solar street lights failure and the reasons
    solar street lights failure and the reasons 2018-08-02

    Solar street lights, that is, on the basis of lighting, using a new supply of solar energy only. But want to adopt the new energy supply, solar panels, batteries, solar charge controller, these components are essential. As we all know, the more simple things, the less failure, and solar street lights are more than three key components, the failure of light than the average will be more. 1. the whole light is not bright Solar street light is used for outdoor lighting, so it will often encounter high temperature and rainy, cold weather and other environments, and solar street light controller is usually installed in the light pole, easily lead to water short to the controller. First of all, observe if there is rust on the controller's terminal. If so, the controller may be damaged, no need to measure the battery voltage. If the voltage of the battery is less than 10.8V, the battery will not be charged. Need to change new one. Re-check solar panel under this working conditions whether the voltage and current has output. If not, that means the solar panel is damaged, need to replace. 2, lamp flashing This failure may be due to poor line contact, battery power loss, a serious decline in storage capacity, if the line is no problem, the need to replace the battery. 3, light a short time If the rainy days duration is short. Storage capacity is generally decreased battery, storage battery caused by insufficient electricity. Replace the battery can be. 4, solar lights incomplete light Now a lot of solar street lamp adopt dot-matrix LED light source, in addition to the quality of LED light source itself, there are some lamp bead Weld will cause this situation. The solution is to replace the corresponding lamp beads, welded firmly or replace the entire lamp head. If the location of the installation of the sun's lack of light, make the overall configuration of the lamp unreasonable, can easily lead to serious shorten the life of solar street lights. Should choose the strong sunlight environment to install, reasonable allocation of solar street light system.

  • MPPT Algorithm Analysis
    MPPT Algorithm Analysis 2018-01-26

    The diagram below shows the volt ampere curve and power curve of solar panel. It can be seen that as the voltage increases, the current always decreases, and the power has the maximum value. MPPT algorithm analysis 1.MPPT overview below is the volt ampere curve and power curve of solar panel. It can be seen that as the voltage increases, the current will always decrease, and the power has the maximum value. The optimal working point for solar panels is called the maximum power point, which depends on the working temperature of the panels and the level of light at that time. Under different temperature and light intensity of different maximum power point of solar panels, to make the maximum power point of solar panels as much as possible to work in, you need to use the photovoltaic maximum power tracking, MPPT technology implementation of the most important thing is to find suitable MPPT control algorithm, can effectively in a rapidly changing weather conditions to track the maximum power point, control panels, work as much as possible on the maximum power point. MPPT has many algorithms, such as constant pressure tracking, incremental conductance and interference observation, etc. (1) Constant pressure tracking method: From the picture above you can see, when the temperature is, the maximum power point of solar panels under different light intensity almost fell on both sides of the same root vertical line nearby, it's likely to approximate maximum power line as a constant voltage V a vertical line, make the photovoltaic panels in a fixed voltage. The constant pressure tracing method is an approximate maximum power tracking method. Constant pressure tracking method has certain power loss. In particular, when the temperature changes, the open circuit voltage of the solar panel changes, while the voltage of the constant voltage tracking method is a constant value, so the tracking efficiency is not high. (2) Incremental conductance method. The conductance increment method outputs the control signal by comparing the conductance increment and the instantaneous conductivity of the solar panel. The working voltage of the solar panel should be increased to reach the maximum power point when the electric conductivity increment of the solar panel and the instantaneous conductivity are greater than 0.When the electric conductivity of the solar panel and the instantaneous conductivity are less than 0, the working voltage of the solar panel should be reduced to reach the maximum power point. The electric conduction increment method is accurate and the response speed is fast, which is suitable for the situation where atmospheric conditions change quickly. However, the requirements of hardware, especially the precision of the sensor, are relatively high, and the response speed of each part of the system is relatively fast, so the hardware cost of the whole system is also high. (3) Interference observation method: The interferometer method is to realize MPPT by c...
