Which locations are suitable for installing distributed PV systems?
A: 1) Industrial plants: Especially in factories with large electricity consumption and relatively high on-grid electricity prices, usually the roof area is large, the roof is open and flat, suitable for installing photovoltaic arrays; at the same time, due to the large power load, distributed photovoltaics Power generation can be eliminated locally, offsetting some of the net purchases, thus saving users' electricity bills;
2) Commercial Building: Similar effect to the industrial park. The difference lies in the fact that commercial buildings are mostly cement roofs and are more conducive to the installation of photovoltaic arrays; however, there are often requirements for architectural aesthetics. According to the characteristics of the service industries such as commercial buildings, office buildings, hotels, convention centers, and resorts, the user load characteristics are generally high during the day and low at night, and can better match the characteristics of photovoltaic power generation;
3) Agricultural facilities: There are a large number of available roofs in rural areas, including their own residential roofs, vegetable greenhouses, fish ponds, etc. The rural areas are often at the end of the public power grid, and the power quality is poor. The construction of distributed photovoltaic systems in rural areas can increase the use of electricity. Guarantee rate and power quality;
4) Public buildings such as municipalities: Due to the unification of management norms, user load and business behavior are relatively reliable, and the installation enthusiasm is high, municipal buildings and other public buildings are also suitable for the concentrated contiguous construction of distributed photovoltaics;
5) Remote farming and pastoral areas and islands: Since they are far away from the power grid, remote farming and pastoral areas in Tibet, Qinghai, Xinjiang, Inner Mongolia, Gansu, and Sichuan, and coastal islands have millions of people without electricity, off-grid photovoltaic systems or Photovoltaic and other energy complementary microgrid power generation systems are ideally suited for applications in these areas.
What kind of building roof is suitable for installing distributed photovoltaic power generation system?
A: At present, domestic building roofs can be divided into three categories according to their shapes: slope roofs, flat roofs and irregular structure roofs. In principle, any type of roof can be installed with photovoltaic system, but when selecting specific installation sites, the slope roof installation should pay attention to the slope and the slope of the roof to match the optimal installation inclination of the component array; irregular roof installation should be considered. While ensuring the efficiency of power generation, it does not affect the architectural artistic effect.
