Details of site selection of Yuguang Complementary Photovoltaic Project

The fish-light complementary photovoltaic project is to set up a photovoltaic array in the fish pond, while the pond can continue to raise fish, and the photovoltaic array can provide a good shielding effect for fish farming. This photovoltaic project model using water power generation and underwater breeding can better solve the contradiction between the development of new energy sources and the large occupation of land. So what should be paid attention to when selecting the location of the Yuguang Complementary Photovoltaic Project?

First, the site selection should pay attention to:

(1) Defining the nature of the land at the site and the status of the right to use, whether it is included in the land use plan;

(2) Identify the engineering geological conditions of the site;

(3) Reasonably evaluate geological structures and seismic effects;

(4) Evaluation of site and adjacent hydrogeological conditions

(5) For sites with large height differences and deep pond depths, the nature and scale of open and fill slopes that may occur after the leveling are to be assessed;

(6) Determine the humanities and conditions around the site, transportation conditions, etc.

Second, the site agreement should be obtained

(1) The planning department agrees with the site construction requirements of the site, whether the site complies with the town planning, and has no contradiction with other planning facilities;

(2) The Ministry of Land and Resources agrees with the site construction requirements of the site, and issues an agreement on the mineral resources with no mining value found in the site area, and whether the ground in the site area occupies the basic farmland;

(3) The forestry department agrees with the site construction requirements of the site, whether the site is located in a national nature reserve, and whether it involves agreements on precious tree species and ancient and famous trees;

(4) The Cultural Relics Bureau issued an agreement on the ground floor of the site area where no valuable cultural relics were found and not in the tourism planning area;

(5) The environmental protection department agrees to the site construction agreement of the site;

(6) The water conservancy department agrees to the site's extraction and drainage agreement.

3. Location analysis of fishing and light complementary projects

Advantages of the location of the fishing and light complementary project:

(1) abundant solar energy resources;

(2) Near the access system substation;

(3) Convenient transportation;

(4) The land is flat and covers a large area.

4. Unfavorable conditions for site selection of fishing and light complementary projects:

(1) The site area is a small reservoir, flooding area, flood detention area, flood discharge area, etc.;

The fishing and light complementary site is located in the flood-stricken area, flood detention area and flood discharge area. The following points should be noted: (1) The site is located in the flood-stricken area, flood detention area, flood discharge area, etc. It belongs to the scope of water conservancy project management, and the project construction needs to be requested. (2) Design of flood control stations for photovoltaic projects and flood prevention of important facilities and equipment; (3) The natural terrain in the site is low, and if necessary, entrust qualified units to carry out flood control evaluation of construction projects. (4) It is necessary to comply with the reservoir development and utilization planning plan and follow the overall scope of the plan; (5) the scope of the reservoir management and the scope of protection should be clearly defined; (6) the standard and service life of the reservoir construction, the design flood level, the check flood level, The elevation of the dam is equal.

(2) The site areas are all along the beach area;

When the fishing and light complementary site is located in the tidal flat, the following points should be noted: (1) The site is located at the beach, river beach, lake beach, etc. It belongs to the scope of water conservancy project management, and the project construction needs to be approved by the competent authority of the Oceanic Administration; (2) It is necessary to clarify the elevation of the tidal flat seawall; (3) the natural terrain in the site is low, and if necessary, entrust a qualified unit to carry out flood control evaluation of the construction project.

(3) The site area is located in the salt field;

The fishing light complementary site is located in the salt field. The following points should be noted: (1) Combine the local geological conditions to comprehensively determine the corrosion of the steel in the concrete structure and reinforced concrete structure; (2) Strong corrosion can cause ground corrosion. It can cause electrical equipment damage, system accidents, strid voltage and contact potential to endanger personal safety. The grounding material of the conventional photovoltaic power station is galvanized flat steel, and the steel plating material should be selected in the strong corrosion area. (3) Strong corrosiveness can cause corrosion of reinforced concrete reinforcement. The design combination address should adopt the integrated structure of piles and columns. The prestressed concrete pipe piles are made of sulfate-resistant Portland cement, admixture with anti-sulfate, and mixed with steel. Corrosion inhibitor, incorporation of mineral admixture, surface coating anti-corrosion coating and other measures.

(4) The site area is the navigable waters;

When the fishing light complementary station is in the navigable waters, the constructor should pay attention to the following points: (1) the depth of the channel; (2) the width of the channel; (3) the turning radius of the channel; (4) the permitted flow rate of the channel; (5) The water profile.

(5) The design period of the reservoir where the site area is located is less than 25 years.

This is mainly due to the fact that the average design life cycle of photovoltaic panels is 25 years. If the waters and reservoirs where the fish-light complementary photovoltaic project is located will exist for less than 25 years, it will cause great waste.
