A solar power generation system is not standardized products, the same configuration is not necessarily appropriate for all users, but the use of the user to design and configuration, in different places, is not the same type of use. In this regard, many customers know better than less, for the intention to install solar power system users, it should choose what kind of solar power system? Make a brief description. First, pure lighting or appliances for use? Solar power system can be divided into two kinds according to their function, one simply DC lighting home lighting system; Second, the lighting and can be used for household appliances have 220V AC output power generation system. Lighting system features a simple, but also the most cost-effective power generation systems, but not for household use. Second, select portable modular machine good or good? Portable machine is also designed and developed a portable, with easy to carry, free installation characteristics, ideal for outdoor camping, but due to the limited size, storage capacity is too small, the cost is very high. Modular requires simple installation, store large capacity, both practical and affordable, as it is more suitable for home users and outdoor home use. Third, off-grid or grid-good? We know that the current main types of solar power systems are off-grid and grid are two, is divided into a grid energy storage and non-storage devices two kinds. The components are each of the differences are not suitable place, the most important is a great difference in cost. In general, the cost of an off-grid systems and network systems are many, energy storage devices and network and those without energy storage devices and network systems. Off-grid solar power system is suitable for use anywhere, but is only suitable for the grid may be incorporated into the public grid place. Fourth, the system capacity size system capacity is the size of the solar power system, generating electricity directly determines how much a day, usually with "W" represents W, and the comb, or whether in the power system from the network, the system Capacity refers to the number of solar panels installed. But for the power system from the comb, and some manufacturers use a power inverter output to indicate the size of the system capacity, which is not a professional representation, should pay attention to the time of purchase. Such models HL3001 of off-grid power systems, we called 300W off-grid power systems, solar panels is 300W, the inverter maximum output power is 1000W, but some sellers will be called 1000W off-grid system, so buyers must Note the size of the solar panels or inverter output size. Therefore, customers in the selection of solar power generation system, the first to be selected according to their own needs or for pure lighting appliances use, and secondly to consider the installation of off-grid or grid. If you are without electricity shortage regions, you can only select off-grid power generation systems; convenient if the electricity in order to save electricity costs, on the choice and power generation systems. In addition, the 1000 watt compact power system, you can choose from an intensive; if it is more than 2000W, you can consider the use of the grid approach. Generally speaking, if it is in remote areas without electricity or recurring power of rural households, choose 10W, 20W, 30W, 40W, 60W, 80W pure lighting systems more affordable. Or if you just solve lighting problems, but also consider the pure lighting system. If you take into account the need to use electric fans and small appliances like television, for example, in the orchard, ranger station, kind Zhi base, outdoor breeding sites, etc., you can choose 100W, 200W, 300W, 400W, 500W off-grid power systems. For the convenience of electricity for families, you can select more than 2000W grid system, China has allowed free network, but the specific rules and procedures also need to contact your local county-level power sector further confirmation. Another consideration is how much solar power systems for their own use it? The choice should be combined with the use of the field consider the specific situation and budget.
