            今天給大家科普一下,自己家里安裝太陽能光伏發電站的話,是并網還是離網 ,需不需要蓄電池?





            Today give you a popular science, if you install solar photovoltaic power stations in your home, is connected to the grid or off the grid, do you need batteries?  




            Off-grid photovoltaic power station  


            This is also called independent photovoltaic power station, which is independent of the power grid and operates independently. It is mainly composed of solar panels, energy storage batteries, charge and discharge controllers, inverters and other components.   The electricity from the solar panel flows directly into the battery and is stored. When it is needed to power the electrical appliance, the direct current in the battery flows through the inverter and is converted into 220V ALTERNATING current. This is a repetitive charging and discharging process.  This kind of power generation system is widely used because it is not restricted by region and can be installed and used as long as there is sunlight. Therefore, it is very suitable for remote areas without power grid, isolated islands, fishing boats, outdoor breeding bases, etc., and can also be used as emergency power generation equipment in areas with frequent power outages.  




            Such systems account for 30-50% of the cost of generating electricity because they must be equipped with batteries.  And the service life of the battery is generally in 3-5 years, and then have to be replaced, which is to increase the cost of use.  In terms of economy, it is difficult to be widely promoted and used, so it is not suitable for use in places where electricity is convenient.  




            However, it is very practical for families in areas without power grid or in areas with frequent power outages.  In particular, in order to solve the lighting problem when power failure, you can use DC energy-saving lamps, very practical.  Therefore, off-grid power generation system is designed for use in areas without power grid or areas with frequent power outages.
