Design of Solar Monitoring System

Solar energy is an inexhaustible clean and environmentally friendly energy. The solar monitoring system adopts remote wireless bridge network technology to realize remote and uninterrupted monitoring without power supply. The solar monitoring system is mainly used in areas with inconvenient wiring in the wild and urban areas, such as real estate construction sites, reservoirs, river water levels, fishing farms, forest farm monitoring, forest fire prevention, island monitoring, border monitoring, individual detection, etc. Then let's learn about the solar monitoring system. Design it! Solar monitoring system design analysis: The photovoltaic power generation device is not connected to the external commercial power grid, but the photovoltaic power generation system that can provide power supply independently is called an off-grid photovoltaic power generation system, also known as an independent photovoltaic power generation system. The off-grid photovoltaic power generation system is mainly composed of photovoltaic power generation devices, energy storage devices, controllers, and inverters. Below, each part is briefly introduced. The general design principle of the photovoltaic system is to determine the small solar cell module and battery capacity under the premise of ensuring that the load power consumption demand is met, and to minimize the investment, that is, to consider reliability and economy at the same time. Before designing a system, the designer must do his best. 1) Simplifying the design as much as possible can improve the reliability of the system. 2) Understand the system efficiency, design the system efficiency reasonably, make the efficiency more than 99% unrealistically, and the cost is high. 3) When evaluating the load, it must be considered comprehensively and leave a certain leeway. 4) Repeated calculation and verification of local meteorological resources to obtain sunshine energy in the region. Miscalculation of sunshine will seriously affect the function of the system. 5) Before designing the solar monitoring system, the installation site should be understood and site inspection should be conducted. This way you understand the characteristics of the device's set-up traces, guards, and zones. 1. Determination of load power: The premise of the solar monitoring system to determine the power and configuration of solar power generation is to determine the power and consumption power of the front-end power supply equipment (load). The experimental detection method can determine the total power P1 of the load, which mainly includes the power of the camera and its heater, the power of the wireless device and the power loss of the inverter conversion. 2. Solar cell array design: The daily power consumption of the load equipment and the system adopts off-grid power supply to calculate the number of solar panels. This design plan uses a single solar panel with a voltage of 12V and a power of p2(w). If the charging loss is ignored, it is calculated based on the average sunshine time of 3 hours per day, taking into account the loss in rainy or snowy days or attenuation, dust, charging efficiency, cloudy days, etc. For charging, the design number of solar panels should be increased according to the full charge days of the battery. 3. Battery pack capacity design: the solar monitoring system battery uses the electric energy (DC) generated by the photovoltaic array for the rear load (inverter and AC load) The life of the battery is determined by many factors such as discharge speed, depth of discharge, number of cycles and operating temperature. The capacity of the battery is extremely important to ensure continuous power supply. In addition to the consumption of equipment, the daily power generation of the solar phalanx also stores part of the power in batteries for use at night and in rainy days. The above is the design of the solar monitoring system. If you want to know more, please feel free to contact us!
