Overview：Solar power generation system is not a standardized product, the same configuration is not necessarily suitable for all users, but according to the use of users to design and configuration, in different places, the use of different types. Many customers know little about this. What kind of solar power system should be chosen for users who want to install solar power system?
Solar power generation system is not a standardized product, the same configuration is not necessarily suitable for all users, but according to the use of users to design and configuration, in different places, the use of different types. Many customers know little about this. What kind of solar power system should be chosen for users who want to install solar power system?
First, pure lighting or household appliances?
According to its functions, solar power generation system can be divided into two kinds: one is the household direct current lighting system used solely for lighting; the other is the 220V AC output power generation system which can be used for lighting and household appliances. Lighting system has simple function and is the most cost-effective power generation system, but it can not be used for household appliances.
Second, is it better to choose a portable machine or a combination machine?
Portable one-in-one machine is also developed and designed for easy portability. It has the characteristics of easy portability and no installation. It is very suitable for outdoor camping. However, due to its limited volume, the storage capacity is small and the cost is high. The combination type needs simple installation, large storage capacity, practical and affordable, because it is also more suitable for household users and outdoor dwellings.
Third, off-grid or grid-connected?
As we know, the main types of solar power generation system are off-grid and grid-connected, and grid-connected is divided into two kinds: energy storage and non-energy storage equipment. Each kind of component has its own difference, suitable place for use is also different, the most important thing is that the cost is very different. Generally speaking, the cost of off-grid system is much higher than that of grid-connected system, and the grid-connected system with energy storage equipment is higher than that without energy storage equipment. Off-grid solar power generation system is suitable for use anywhere, and grid-connected is only suitable for places with public power grid that can be merged.
Fourth, the system capacity
System capacity refers to the size of solar power generation system, which directly determines the amount of electricity generated in a day. Usually, W is used to express watt. Whether in grid-connected or off-grid power generation system, system capacity refers to the number of solar panels installed. However, for off-grid power generation system, some manufacturers use the output power of the inverters to represent the size of the system capacity, which is a non-professional expression, and should be paid attention to when purchasing. For example, model HL3001 off-grid power generation system, we call it 300W off-grid power generation system, the battery board is 300W, the maximum output power of the inverters is 1000W, but some sellers will call it 1000W off-grid power generation system, so buyers must pay attention to the size of the battery panel or the output size of the inverters.
Therefore, when choosing solar power generation system, customers should first choose pure lighting or household appliances according to their own needs, and secondly consider whether to install off-grid or grid-connected. If there is no electricity shortage area, we can only choose off-grid power generation system; if the electricity is convenient, in order to save electricity costs, we choose grid-connected power generation system. In addition, for small power generation systems under 1000W, the off-grid mode can be chosen; if it is above 2000W, the grid-connected mode can be considered as far as possible.
