Solar photovoltaic carports are very popular in foreign countries. It mainly combines photovoltaic modules and carport roofs, which can not only meet the parking demand, but also supply power to the grid, increase revenue, and photovoltaic power generation is energy-saving and environmentally friendly. At present, the country has begun to vigorously promote solar photovoltaic carports to meet the current parking demand. For large hospitals with limited land, building a green and energy-saving photovoltaic carport is an effective solution.

Background and characteristics of photovoltaic carport

Photovoltaic power generation system is a power generation system that uses solar cells to directly convert solar energy into electrical energy. Its main components are photovoltaic modules and inverters. It is characterized by high reliability, long service life, no environmental pollution, independent power generation and grid-connected operation. It is favored by enterprises and organizations in various countries and has broad development prospects.

Photovoltaic carport type

The photovoltaic carport is mainly composed of a support system, an array of battery components, a lighting and control inverter system, a charging device system, and a lightning protection and grounding system. The support system mainly includes support columns, diagonal beams fixed between the support columns, purlins connected to the diagonal beams to support the solar cell assembly array, and fasteners for fixing the cell assembly array.

There are various types of photovoltaic carport brackets, and the conventional ones can be divided into single-column unidirectional, double-column unidirectional, and single-column bidirectional.

Photovoltaic power generation in the carport

This is a new type of power generation, and it is also a future development trend. Early installation will benefit early. As long as the photovoltaic module power generation system is installed on a sunny roof, solar energy can be converted into electrical energy to supply residents daily life or industrial plants. Use electricity. Rooftop power generation is different from the traditional centralized ground photovoltaic power generation. It has the characteristics of miniaturization and decentralization, which is economical, efficient and reliable. Distributed photovoltaic power stations can be installed in places exposed to sunlight, such as industrial plants, residential roofs, balconies, sun rooms, and the ground.

Energy saving can also bring benefits

Photovoltaic carports came into being. The combination of photovoltaic modules and the roof of the carport saves costs compared to installing photovoltaic modules on the top of the carport. Not only can it achieve all the functions of the traditional carport, it can also generate electricity to bring benefits to the owner. Generally, steel structure brackets are used, which are simple, generous, fashionable, beautiful, and are clean and environmentally friendly new energy sources, which can effectively alleviate the environmental and energy pressures of the society.

In particular, a distributed photovoltaic grid-connected system refers to a user-side grid-connected power generation system that uses photovoltaic components to directly convert solar energy into electrical energy. This system is located near the user, and the generated power can be used on-site. It is connected to the grid at a voltage level of 10 kV and below, and the total installed capacity of a single grid point (380V) does not exceed 6 MW. A single grid point on the 220V user side The total installed capacity does not exceed 8 kilowatts.

The cloth-type photovoltaic power generation system can be installed in any place where there is sunlight, including the ground, the top of the building, the side elevation, the balcony, etc., including the roofs of schools, hospitals, shopping malls, villas, residential buildings, factories, enterprises and institutions, and carports. , The top of the bus stop sign is the most widely used; concrete, color steel plate and tile roof can be installed.

Types of photovoltaic carports

The types of photovoltaic carports are divided into two-carports and multi-carports. Most of them are modular in design and can be used alone or in multiple combinations for easy expansion. There are as few as a few parking spaces, as many as hundreds of parking spaces, with strong flexibility. If ordinary photovoltaic modules are used, the overall cost is lower. If the installed capacity is large, the rate of return is high and the investment recovery period is short.

Photovoltaic carports, one of the simplest and most convenient ways to combine photovoltaics and buildings, have become more and more popular in recent years. The photovoltaic carport has good heat absorption, convenient installation, and low cost. It not only makes full use of the original site, but also provides green and environmentally friendly energy. The construction of photovoltaic carports in factory parks, commercial districts, hospitals, schools, etc. can solve the problem of high temperatures in outdoor parking lots in summer.
