Product Description

Industrial and commercial roofs have always been the darlings of the photovoltaic industry. Using idle industrial and commercial roofs to construct photovoltaic projects can not only reduce energy consumption, but also make full use of idle resources, which plays a role in energy conservation and emission reduction, and can bring huge economic benefits to enterprises. Benefits and environmental benefits can be said to serve multiple purposes.

The main advantages of JDSOLAR industrial and commercial roof distributed photovoltaic power generation system:

1. Reduce the use of high-priced electricity and peak electricity, and reduce business operating costs.

2. The investment recovery period is short and the rate of return is high.

3. Enjoy national and local subsidies and enjoy economic benefits.

4. Energy saving and emission reduction, low carbon emission, environmental protection and green.

5. The system is stable and reliable with a service life of over 30 years.

6. Modular design, convenient and flexible, simple later maintenance, no worries.

There are a lot of independent commercial roofs in China, such as supermarkets, shopping malls, parking lots, clubs, clubs, etc. These buildings have a lot of idle roofs, which can be used for spontaneous self-use surplus electricity Internet access projects.

Installation requirements for JDSOLAR industrial and commercial photovoltaic power generation

1. Local resources

For distributed photovoltaic site selection, priority should be given to areas with large solar radiation, less rainy weather, and less pollution. If the company is near the sea, anti-salt mist, anti-corrosion and anti-typhoon measures should be considered; if the area where the company is located is large, anti-sand and sand washing measures should be considered; if in cold areas, anti-freezing and snow removal measures should be considered.

2.Building roof conditions

Building ownership, design life, materials, area and orientation also directly affect the feasibility and installation of distributed photovoltaic power plants.

Building property rights are owned by the business owner or local government, which is suitable for development; the leased factory building is not suitable. During the development of the project, it is necessary to understand the useful life of the roof. The remaining useful life is too short to be developed.

At the same time, the azimuth of the roof, the tilt of the roof and the surrounding obstructions need to be measured during the survey, so as to determine the installed capacity and power generation of the system later.

3. Building roof load

The photovoltaic power plant needs to operate for 25 years. During the project inspection, it is necessary to focus on the design value of the constant load in the architectural design specification.

During the project survey, the project developer is required to obtain the house structure drawing from the owner to facilitate the calculation of the roof load.

4. Distribution facilities and grid connection points

Power distribution equipment is one of the basis for selecting grid-connected solutions for photovoltaic power stations. The main examination contents are:

1) Plant transformer capacity, quantity, bus coupling, load ratio, etc .;

2) Factory meter position, busbar specifications, switch specifications and models;

3) Whether the factory area is equipped with an independent power distribution room, whether there is a spare interval for power distribution equipment, and if not, can the busbar be crimped;

4) Prefer users with large transformer capacity and large load ratio;

5) Check the capacity of the main switch of the incoming line, and consider the revenue problem. The output current of the photovoltaic power generation system should not be greater than the capacity of the household switch;

6) Based on the principle of convenient and economical wiring, consider the installation position of the inverter and grid cabinet.

5. User electricity consumption and electricity price

The most important thing of distributed photovoltaic power generation project is the local consumption of the generated power, so we need to examine:

1) The average annual, monthly, and daily power consumption of the enterprise, the day-to-day power consumption, and the peak time and proportion of power consumption;

2) Enterprise electricity price, weighted electricity price during the day.

Commercial and industrial photovoltaic power generation has become a mainstream!

At present, logistics, ports, schools, hospitals in many provinces and cities, as well as the roofs of residents and the roofs of enterprises and institutions are still idle. From an investment perspective, because of state subsidy support and continuous operation for 25 years, industrial and commercial photovoltaic power generation systems are considered to be a better investment method. Because industrial electricity prices are more expensive than residential electricity prices, the electricity costs saved are generally more than 5- Pay back in 7 years.
