Cost Analysis of Solar Power Station - Photovoltaic Support

Publish Time:2022-08-29 Sources:
As an important part of photovoltaic systems, various designs of solar mounts and multi-dimensional assessment and evaluation have attracted more and more attention in the industry. As the cost of photovoltaic systems is getting lower and lower, the situation of the location of photovoltaic power plants is becoming more and more complex and diverse, and the requirements for photovoltaic solar mount system in the industry are getting higher and higher. These requirements are not only reflected in low cost and safety and durability, but also require their It needs to be able to adapt to and resist various external factors such as soil, atmosphere, wind and snow that can be expected and unpredictable in the future. Moreover, since other components in the photovoltaic system are also showing a trend of more and more varieties, the photovoltaic solar bracket should not only meet the In addition to its own quality and safety, it is necessary to consider various types of photovoltaic modules together, not only to meet the requirements of the total carrying capacity of the system that integrates the modules, but also to help the modules to maximize the power generation efficiency, thereby improving the overall photovoltaic system performance.
solar mount system

The solar mounting system is divided into two categories: fixed solar mountings and tracking solar mountings. The common fixed solar mountings can be divided into ordinary fixed solar mountings, fixed and adjustable solar mountings, etc. The common tracking solar mountings are flat single Axis tracking solar mount, oblique single axis track solar mount, dual axis track solar mount, etc. In recent years, in addition to the above-mentioned common types of solar mounts, a relatively "unpopular" type, flexible solar mounts, has also appeared on the market. The emergence of flexible solar brackets solves the special environments where solar brackets cannot be installed, such as large-span environments such as sewage pools, barren mountains, wastelands, tidal flats, and fish ponds.


Factors Affecting Solar Mounts
1. Latitude
Flat uniaxial is suitable for low latitude areas, but not suitable for high latitudes;
Adjustable solutions should not be used in low latitude areas, but suitable in high latitude areas;
The optimal inclination angle may not be used in areas with high latitude.
2. Climate
Tracking and adjustable inclination should not be used in the area dominated by scattered radiation;
Flexible brackets should not be used in strong wind areas.
3. Field area
Fixed area should be used in tight and scattered areas
4. Geology/Roof
Roof Projects Don't Consider Tracking
5. Terrain
It is not suitable to use tracking and fixed adjustable type for complex terrain;
In areas with large-span requirements such as local steepness and water surface, flexible supports should be used.
6. Geomorphology
Flexible brackets can be considered for areas involving complementary demand for forest light and agricultural light.

Application Scenarios of Solar Mounting System
Carport photovoltaics mostly use high-strength lightweight aluminum alloy and steel structure material to fix the bracket, which has the advantages of anti-corrosion, no rust, beautiful appearance, and easy installation.
Cement roof buildings have a long service life and high bearing capacity. There are many types of foundations and layout options. The commonly used forms are counterweight brackets and planting reinforcement brackets.
The color steel tile roof has a large area and relatively few roof obstacles, but the bearing capacity is doubtful. Most of them can only be tiled, and fixture brackets are commonly used.
Due to the small and scattered area of tile roofs, large differences in bearing capacity, and many surrounding obstructions, hook brackets are often used.
Solar Mounting System Price
According to experience, the price of solar brackets on the market currently ranges from 0.2-0.45 yuan/w, depending on the material and the price of the material at that time. For example, hot-dip galvanizing has recently been in short supply in the market after the production of hot-dip galvanizing manufacturers in Tianjin has stopped, resulting in a soaring price and an increase of about 0.04-0.06 yuan/w of construction cost. Considering the recovery of steel prices and the improvement of environmental protection requirements, there is a possibility of price increases for brackets such as hot-dip galvanizing.
Flexible brackets are currently mainly used in special scenarios, and the price of brackets is around 0.8-0.9 yuan/w
