Rooftop photovoltaic power generation system is characterized by high investment returns, does not occupy land resources, outstanding environmental protection benefits, alleviate electricity shortage, flexible operation, etc., of which flexible operation refers to the effective interface between the rooftop photovoltaic system and the smart grid and micro-grid, flexible operation, under appropriate conditions can also achieve local off-grid power supply operation, and in general, as long as the roof can be installed photovoltaic power generation system. What are the characteristics of the specific rooftop photovoltaic power generation system and as long as the roof can be installed photovoltaic power generation system these problems, let’s take a closer look at it in the article!
what are the characteristics of the rooftop photovoltaic power generation system?
The roof photovoltaic power generation system has a wide range of applications and broad application prospects in urban and rural construction, industry, agriculture, transportation, public facilities and other fields, which is not only an important force to promote the revolution of energy production and consumption, but also an important measure to promote “stable growth, promote reform, adjust the structure, and benefit people’s livelihood”. So what are the characteristics of rooftop photovoltaic power generation systems?
1. High investment return
The output power is relatively small, and the return on investment is not low. Generally a single rooftop PV system project has a capacity of a few kilowatts to several hundred kilowatts. The size of the capacity of the photovoltaic power generation system has little impact on the power generation efficiency, so the impact on its economy is also very small, that is, the investment yield of the small photovoltaic power generation system is not lower than that of large photovoltaic power plants.
2. Do not occupy land resources
The rooftop photovoltaic power generation system basically does not occupy land resources, can make full use of the surface of the building, can generate electricity and power nearby, and does not use or reduces the use of transmission lines, reducing transmission costs. Photovoltaic modules can also directly replace traditional wall and roof building materials.
3. Outstanding environmental protection benefits
The pollution is small, the environment is friendly, and the environmental protection benefits are outstanding. Rooftop photovoltaic systems do not consume fuel, emit no substances including greenhouse gases, have no noise, and do not pollute the air and water during the power generation process.
4. Relieve electricity tension
The rooftop photovoltaic system is connected to the distribution network is the coexistence of power generation and electricity, and the power supply in the grid is at the peak of the power generation, which can effectively afford the role of the peak, reduce the city’s expensive peak power supply load, and alleviate the power shortage in local areas to a certain extent.
5. Flexible operation
The rooftop photovoltaic system has an effective interface with the smart grid and microgrid, the operation is flexible, and the local off-grid power supply operation can be realized under appropriate conditions.
Can solar panels be installed on any roof?
Home photovoltaic power generation is generally composed of solar cell packs, solar controllers, batteries, its investment is small, construction is fast, the footprint is small, and once built, it can not only save electricity costs, but also enjoy the benefits after a few years, so it is favored by consumers. So as long as it is a roof, can a photovoltaic power generation system be installed?
Yes, almost all home roofs can be equipped with solar energy systems, such as: flat roof, sloped roof, various tiles, all kinds of color steel plates. Most of the photovoltaic modules on the market now are 60 cells, weighing about 20kg/block, so the general roof will not have much problem in terms of load-bearing.
