We provide professional knowledge to let you understand solar lighting system, including outdoor solar lighting system
The placement form and placement angle of the solar cell array in the photovoltaic system have a great influence on the solar radiation received by the photovoltaic system, thereby affecting the power generation capacity of the photovoltaic power supply system. The following two angle parameters are related to the placement of the solar cell array: […]
The capacity configuration of the solar LED lighting system mainly includes the calculation of the load power consumption, the power calculation of the solar cell array, the calculation of the optimal inclination angle of the installation, and the calculation of the battery capacity. In the solar LED lighting system, LED lamps, solar cell array power […]
Solar energy is a clean energy with many advantages, but it also has great shortcomings: large dispersion, low density, and light intensity is greatly affected by seasons, climate and environment, so how to use solar energy efficiently has always been a problem that plagues people’s design. In order to improve the utilization rate of solar […]
The solar photovoltaic lighting system usually adopts an independent power supply system, and the reliability of the system largely depends on the performance of the controller. At present, the controllers mainly include parallel type, series type and pulse width modulation type. Parallel controller The parallel controller is also called a bypass controller. When the battery […]
In photovoltaic power generation systems, especially photovoltaic lighting systems, the battery is in a deep discharge cycle every day. Usually, the depth of discharge is 25% to 35% every day and night. It is very important to detect and control the battery to avoid over-discharging. The discharge characteristic curve of lead-acid battery is shown in […]
In the photovoltaic power generation system, the input of electric energy generated by solar energy is not stable, so the control of the photovoltaic system brings uncertainty. In addition, the various components of the system also change with the environment and use time, so reasonable charging control to reduce the damage to the battery has […]
In the independent solar photovoltaic lighting system, the control system defines and controls the charging and discharging conditions of the battery, and controls the power output of the solar cell components and the battery to the load according to the power demand of the load, which is the core control part of the entire system. […]
Valve regulated lead acid battery (VRLA battery for short) was born in the 1970s. Although this battery is also a lead-acid battery, it has many advantages compared with the original lead-acid battery, and is popular with users, especially for users who need to install battery supporting equipment together (or a workshop), such as UPS, telecommunications […]
After understanding the charging and discharging characteristics of battery, how to control the charging and discharging process is the key to the application of battery in photovoltaic power generation system. In 1967, American scientist J.A. MAS made a lot of experimental research on the gas evolution problem in the charging process of lead-acid batteries, and […]
1. The development of lead-acid batteriesThe lead-acid battery was invented by Plante in 1859 and has a history of more than 100 years. Since its invention, lead-acid batteries have always had an absolute advantage in chemical power sources. This is because of its low price, easy availability of raw materials, sufficient reliability in use, suitable […]
