You are familiar with solar photovoltaic power generation grid-connected systems, how much do you know about off-grid systems? solar street light-

Electricity consumption is a matter of course, but in recent years, my country has used a large number of solar photovoltaic power generation off-grid systems in the power consumption projects in areas without electricity, allowing people in remote areas to use clean energy solar photovoltaic power generation, solving the problem of no electricity. Power or power shortage problem! At present, the solar photovoltaic power generation grid-connected system has received enough attention and the technology is mature, but in places with no electricity or lack of electricity, the solar photovoltaic power generation off-grid system is a rigid demand. Off-grid solar photovoltaic power generation system, also known as independent solar photovoltaic power generation system, is mainly composed of photovoltaic solar power generation panels, charge controllers, off-grid inverters and loads. Solar photovoltaic power generation off-grid systems are mostly used in areas far away from large power grids, such as the Gobi, beaches, islands and other areas. The solar photovoltaic power generation off-grid system has good reliability, is used in high altitude and harsh environments, and has good durability. The life of photovoltaic solar power generation panels is about 20-25 years. Low maintenance cost and can be unattended. Energy saving and environmental protection, solar energy is inexhaustible, and does not produce any greenhouse gas emissions. Before designing a solar photovoltaic power generation off-grid system, the preliminary work should be done well. It is necessary to understand the climatic conditions, load type and power of the user's installation site; electricity consumption during the day and night, of course, the user's budget and economic situation should also be clearly understood , Photovoltaic solar power station off-grid system, electricity depends on the weather, there is no 100% reliability, this must be made clear with customers. For the consumption demand of solar photovoltaic power generation off-grid system, customers are divided into two categories: one is poor households in remote areas; The solar photovoltaic power generation off-grid system is different for customers. The design is flexible, rather than sticking to a certain fixed formula. Yangzhou Global Solar Technology Development Co., Ltd. adopts different design solutions for different customer groups, and tries to satisfy customers as much as possible. actual needs!
