219.3546 hectares. According to the official website of the Chengde Municipal People's Government, the pumped storage power station in Kongjiagou Village, Dashizhuxi Township, intensively saves 59.11 hectares (887 acres) of land, covering an area of 219.3546 hectares . Kongjiagou Village, Dashizhuxi Township, mainly composed of upper reservoir, lower reservoir and underground water transportation and power generation system. The power plant has an installed capacity of 1,400 megawatts, an upper reservoir storage capacity of 11.67 million cubic meters. a lower reservoir storage capacity of 10.9 million cubic meters and a design water height of 618 meters.
It is always a good idea to install photovoltaic energy production on roofs. If you install solar panels on the roof, you can efficiently use solar energy to produce electricity.ctricity and save electricity. The state now provides subsidies for the installation of power strips. With solar power, we generally use less electricity, saving electricity for your home. Installing photovoltaic power generation on the roof is relatively simple, generally speaking, it can be installed by a few workers in half a day.
1. Rooftop photovoltaic power generation is a mature technology that involves installing solar panels on top of the building and combining the existing building with the photovoltaic system. Use existing buildings efficiently without taking up additional land resources. It can generate electricity locally and consume electricity nearby, thereby reducing transmission losses. Photovoltaic energy production occurs during the peak electricity consumption periodricity during the day, which can effectively alleviate peak electricity demand. The state actively promotes the possibility of producing electricity if solar panels are installed. Unused electricity can also be sold to the State Grid and benefit from corresponding subsidies. It can be connected to the electricity grid, which means that you need to install two electricity meters in your home, one for the electricity supplied by the electricity company and the other for the electricity produced by the solar panels.
2. The construction of a photovoltaic plant requires support, which must be built on the roof or in an open space. Property rights to the roofs of urban buildings belong to all owners. If someone wants to build a photovoltaic plant on the roof of a building, they must not only obtain the consent of all owners, but also involvethe property management company, the urban management bureau and other units. Many people in the city want to pretend, but it is not easy to do so. When installing, professional installers will design and install it reasonably according to the local climate. The photovoltaic plant will have no problem withstanding strong winds of magnitude 8 to 10.
3. Since the photovoltaic power generation system requires drilling holes in the roof during installation, if it is improperly installed or handled improperly, it is easy to damage the roof, resulting in leakage accidents. water, mold, etc. ., and higher maintenance costs in the future. One of the most obvious disadvantages of installing solar PV power generation on your roof is that PV power generation destroys the waterproof layer of the house. The above is the answer to the questionquestion whether it is good or bad to install photovoltaic energy production on roofs and why.
