Our home installation of luoyang is hooked up to the price of solar street light system

On their roof installation of photovoltaic solar panels can have their own solar power station, but a lot of customers to choose to install home solar power systems and confused, is to install solar photovoltaic grid-connected and off-grid system, need to

if you are in the roof installation of photovoltaic solar panels, you can have your own solar power station. However, many customers choose to install the household solar power generation system is still confused. You need to install the battery photovoltaic (pv) grid or off-grid system? Solar photovoltaic power station in the grid system is must be connected to the public grid and must rely on existing power grid operation of power systems. Grid system is mainly composed of photovoltaic solar panels and inverters. Photovoltaic solar panels by 220 v ac inverter directly, for household appliances power supply. When roof solar power station power output more than household appliances use of power, power is transmitted to the rest of the public power grid. However, when the solar photovoltaic power generation system of power generation capacity can't meet the use of household appliances, it automatically added from the grid. The whole process of intelligent control, without manual operation. Do not need battery solar photovoltaic power grid system, greatly saves the cost. In particular, new interconnection policies issued by countries made it clear that as long as the domestic solar power station power, they will receive state subsidies, and free access to the grid. The rest of the power can also be sold to the electric power company. From the perspective of long-term investment, according to the service life of 25 years of domestic solar power station, costs can be in 6 - 10 years or so, the rest can earn 10 years or so. So, if you want to save electricity and power supply convenient, you should choose the interconnection of household solar pv power generation system, which is the current mainstream way. Solar photovoltaic power generation off-grid system is also called independent photovoltaic solar power plants. It is a independent of the power grid operation of the power system, is mainly composed of photovoltaic solar panels, storage batteries, charge and discharge controller, inverter, etc. Photovoltaic solar panels generate electricity directly into the battery and storage. When the need for electric power supply, battery in the direct current flows through the inverter, translates into 220 v ac, this is a repeated charging and discharging cycle. Solar photovoltaic power generation off-grid system is widely used for footloose. It can only install and use in sunny places. Therefore, it is very suitable for no power grid remote areas and islands, fishing boats, outdoor breeding base, etc. , also can be used as a frequent power outages areas of emergency power generation equipment. Solar photovoltaic power generation off-grid system must be equipped with battery, and 30 - of the cost of power generation systems 50%. But for no power or often in areas of family, this is also very practical. In particular, the DC energy saving lamps can be simply used to solve the problem of power failure of lighting, very practical. Therefore, solar off-grid system is specially designed for no power or often in region. In short, solar photovoltaic power station in the grid system does not need battery, off-grid system need battery.
