Distributed photovoltaic power generation refers to a distributed power generation system that uses photovoltaic modules to directly convert solar energy into electricity. It is a new, has the broad prospects for development of the power and the way of comprehensive utilization of energy, it advocates the nearby power, came to the interconnection and nearby transformation, using the principle of near, not only can effectively improve the capacity of the same scale photovoltaic power station, it also effectively solves the power loss in the booster and long-distance transportation problem.
The most widely used distributed photovoltaic systems are those built on the roofs of urban buildings. Such projects must be connected to the public grid to supply electricity to nearby customers. So where are the best places to install distributed photovoltaic systems?
1, industrial plants: especially in the electricity consumption is relatively large, online shopping price is relatively expensive factories, usually factory roof area is large, the roof is open and smooth, suitable for the installation of photovoltaic arrays; In addition, due to the large power load, the distributed photovoltaic grid-connected system can absorb local consumption and offset part of the online shopping power, thus saving users' electricity bills.
2. Commercial Buildings: Similar to the effect of the industrial park, the difference is commercial building is concrete roof, more advantageous and installation of pv array, but usually have requirements of architectural aesthetics, according to the shopping malls, office buildings, hotels, conference center, resorts and other service industry characteristics, user load characteristic is generally characterized by higher during the day, night is low, to better match the photovoltaic properties.
3, agricultural facilities: there are a large number of available roofs in rural areas, including the roofs of their own houses, vegetable greenhouses, fish ponds, etc. Rural areas are often at the bottom of the public grid, and the power quality is poor. The construction of distributed photovoltaic systems in rural areas can improve the power security and power quality.
4. Municipal and other public buildings: due to unified management standards, relatively reliable user load and business behavior, and high enthusiasm for installation, municipal and other public buildings are also suitable for centralized connected construction of distributed photovoltaic.
5. Remote farming and Pastoral areas and islands: Due to the distance from the power grid, there are millions of people without electricity in remote farming and pastoral areas of Tibet, Qinghai, Xinjiang, Inner Mongolia, Gansu, Sichuan and other provinces as well as coastal islands of China. Off-grid PHOTOVOLTAIC system or micro-grid power generation system with other complementary energy is very suitable for application in these areas.
