Centralized Photovoltaic Solutions

Centralized Photovoltaic Solutions

Brice Solar's centralized photovoltaic solutions in China make full use of land or seawater resources in conjunction with light resources to achieve a highly efficient integration of eco-efficiency and power generation, self-sufficiency of energy for electricity consumption, and reduced dependence on the commercial grid.

I. Core Features

Concentrated PV solution refers to the large-scale installation of PV modules, the module equipment is usually megawatt or gigawatt level, in order to form a centralized power station, the solar energy will be converted into electricity, and then boosted and integrated into the high-voltage power grid for long-distance transmission to the area of electricity consumption. Its core features include:

1. Scale deployment:

The power station is concentrated in the desert, Gobi and other remote areas rich in light resources, covering a wide area, by reaching hundreds to thousands of acres, the installed capacity can reach more than 100 megawatts.

2. High-voltage grid connection

The power is converted into alternating current by inverters, and then connected to 35kV or 110kV high-voltage transmission network through the booster station, and then uniformly deployed by the power grid.

3. Centralized operation and maintenance:

A professional team is required to manage equipment monitoring, fault troubleshooting and regular maintenance, relying on an intelligent operation and maintenance platform to improve efficiency.

Ⅱ.PV System Composition

1. Photovoltaic Array

PV array consists of a large number of PV modules, such as monocrystalline silicon and polycrystalline silicon in series, and optimizes the angle of light reception through fixed or tracking bracket. 2.

2. Inverter

Centralized or string inverters are used to convert DC power into AC power to support high voltage grid connection.

3. Boosting and Transmission System

Adopt step-up transformer to step up the low voltage power (e.g. 380V) output from inverter to high voltage above 35kV.

Using transmission lines, the power is transported over long distances through the high-voltage grid to load centers in cities or industrial zones.

Through the use of an intelligent monitoring platform, real-time monitoring of power generation, equipment status and environmental parameters, predicting power generation efficiency and optimizing operation and maintenance strategies

Ⅲ.Typical Photovoltaic Complementary Programs

1. Agriculture and PV Complementary Program

Complementary agriculture and PV cleverly combines PV power generation with agricultural cultivation, so that the same piece of land can generate electricity and cultivate land, greatly improving the land utilization rate. At the same time, farmers get additional income through PV power generation, while agricultural planting land brings stable income, realizing win-win economic benefits. The protection of greenhouse facilities protects crops from natural disasters and enhances the products and quality of crops.

2. Forestry and photovoltaic complementary program

Forestry and photovoltaic complementary ingenious combination of forestry planting and photovoltaic power generation, to enhance the land utilization rate, to achieve a win-win situation of ecology and economy. This program can realize the multi-purpose use of one land, forest trees breeding ecological value, photovoltaic panels into economic value, to build a diversified green economy. Forestry and photovoltaic complement each other, not only the economic benefits are significant, there are also outstanding ecological benefits, such as wind and sand control, reduce greenhouse gas emissions, social benefits are obvious.

3. Mountain PV Program

Mountain photovoltaic has flexible adaptability, overcoming complex terrain challenges, showing strong terrain adaptability. It generates electricity efficiently, makes full use of idle mountain land, and maximizes the use of land resources. At the same time, as a clean energy source, it contributes to environmental protection and guards green water and green mountains. With the advancement of technology, its economic benefits are becoming more and more prominent, creating income for local residents and promoting industrial development. Moreover, low maintenance costs and stable operation make it economical for long-term operation.

4. Mudflat Photovoltaic Program

In the vast wetlands and riverbanks of the mudflats, through the laying of photovoltaic power plants, turning waste into treasure, not only saving arable land, but also realizing the efficient use of land resources. The flat mudflats and low vegetation allow the PV panels to enjoy the sunshine bath and the photovoltaic conversion efficiency soars. Compared with traditional PV, beach PV is more environmentally friendly and harmonious, avoiding the occupation of arable land and reducing environmental damage. With little wind and plenty of light, it is a precious place for photovoltaic power generation.

5. Sea surface photovoltaic program

In the vast ocean for photovoltaic power generation opened up a new world. Floating platform, offshore structure, clever solution to the problem of land scarcity, solar energy utilization is more efficient. The vastness of the ocean allows PV panels to enjoy unobstructed sunlight and generate more power than on land! Moreover, the stable environment of the ocean brings more reliable energy supply. Sea surface photovoltaic, not only release the land resources, but also more environmentally friendly, less ecological impact.

6. Fisheries and photovoltaic complementary program

The construction of PV power station on the water surface of fishery farming makes full use of the space of the waters without taking up additional land, which not only improves the land utilization rate, but also reduces the ecological impact and improves the water quality, and at the same time brings the double economic benefits of fishery and photovoltaic. In addition, it makes full use of solar energy resources, reduces dependence on traditional energy sources, realizes energy saving and emission reduction, and provides clean and sustainable energy for the local economy.
