We provide professional knowledge to let you understand solar lighting system, including outdoor solar lighting system
When light passes through the smooth interface and enters the second medium, it will change direction according to the following rules: the incident ray, the refracted ray, and the interface normals passing through the incident ray and the point of incidence are all in the same plane; as shown in Figure 1, if the incident […]
①Regular reflection and specular reflection (regular reflection, specular reflection) The reflection generated on a smooth interface is called specular reflection, also known as regular reflection. As shown in Figure 1, an incident ray will generate a reflected ray, and the relationship between them is as follows: the incident ray, the reflected ray, and the interface […]
In physics, the process of emission and transmission of energy in the form of electromagnetic waves or photons is called electromagnetic radiation. Light is a part of electromagnetic radiation, which is electromagnetic radiation with wavelengths between the transition region to X-rays (λ≈1 nm) and the transition region to the radio band (λ≈1 mm). Not all […]
Lighting has changed the way of life that people “work at sunrise and rest at sunset”, extending the space and time of human activities, and lighting has become an irreplaceable requirement in today’s modern lifestyle. Lighting is generally divided into two categories: natural lighting and artificial lighting. Natural lighting is limited by natural conditions, and […]
In the design of photovoltaic system, in addition to the design of battery capacity and the size of solar cell array, we should also consider how to select appropriate system equipment, that is, how to select solar cell array, battery, controller, cable, junction box, module support that meet the needs of the system. The selection […]
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 […]
