182, 210 Photovoltaic technology route dispute: regardless of "white cat or black cat", seizing more profits is a "good cat"

In 2019, single crystal surpassed polycrystalline in one fell swoop and became the mainstream of the photovoltaic market.

The large silicon wafer itself is the general trend, and it is also the inevitable development of the photovoltaic industry.

At present, the discussion on which is the better one between the two is still going on.

Power station cost: Whose is lower?

Generally speaking, the industry divides the total cost of photovoltaic power generation into component cost and bos cost excluding components.

Therefore, in actual projects, the impact of 182 components and 210 components on the cost of the boss has a real reference value.

It can be clearly seen from the table that three types of silicon wafers of 166, 182 and 210 are used in photovoltaic projects of the same scale located in the high, medium and low latitudes, and there is a relatively obvious difference in the amount of engineering in the support, foundation piles and land.

Mounting costs are the bulk of the bos cost of photovoltaic projects, generally accounting for about 10%.
It can be seen from the chart data that under the same area and the same total installed scale, the total number of brackets required for 166 modules is the largest, followed by 182, and the smallest is 210 size.
Take the Ulan Mulun area as an example.
Compared with 166,210 stents, the demand is reduced by 3250, and the cost is reduced by 37.
5%; compared with 182,210, the demand for stents is reduced by 1,800 sets, and the cost is reduced by 25%!

　　In this way, the 210 component can reduce the cost of the traditional boss by 30-40% because of its size and power advantages; compared to the 182, it also has a 25% cost advantage.
When calculating the cost of electricity per kilowatt hour, it can be reduced by up to 0.
1 yuan/w!

　　In addition, the 210 module and the 182 module have a larger front-to-back center distance than the 166 module.
This also means that under the same installed scale, the larger the spacing, the less the number of piles required.
In addition, in fishing and light complementary projects, the pile height has risen from the general range of 3-5 meters to 10-12 meters, or even higher.
In this way, the decrease in the number of piles required by the project will bring about a more significant cost reduction effect.
In this regard, 210 components do the best.

　　Land costs are also a big part of photovoltaic projects.
From the data in the table, we can see that among projects of the same scale in the same area, 166 requires the largest land area, 182 is the second, and 210 requires the smallest land area.
In the northwest region where the unit price of land is relatively low, the difference in land area is negligible; but in the central and eastern regions, where the cost of land is higher, the advantage of 210 in saving land will be magnified.

　　The reduction in demand for brackets, piles, and land area will reduce the overall installation and construction cycle and cost of photovoltaic projects.
Through the above data comparison, it is not difficult to find that the cost reduction effect of 210 components in actual projects is better than that of 166 and 182.

　　Investment income: whose is higher?

　　"Regardless of black cat or white cat, a good cat can catch a mouse" is also applicable in the photovoltaic industry.
In the coming era of parity online, cost control is king.
There are many module specifications in the photovoltaic market, and what determines the value of the investment is the return.

　　It can be seen from the overall cost table of the three locations and three specifications of silicon wafer projects by Shandong Electric Power Engineering Consulting Institute Co.
, Ltd.
that, thanks to the realization of greater power, the overall cost of the project using 210 components is lower than 182 and 166 project.

　　In the era of parity, new photovoltaic power generation projects will completely bid farewell to subsidies.
Therefore, every cent or cent of electricity cost reduction will bring greater benefits to the project.
The above comparison also stays on 500w power modules.
After 210 modules generally enter the 600w era, the cost of photovoltaic projects in the future will be further reduced.

　　It is worth noting that the power generation cycle of photovoltaic projects is generally more than 25 years.
In this way, in the whole life cycle, operation and maintenance costs will also increase the total input cost of photovoltaic projects.
The 210 component project with fewer brackets, piles and fewer lines can reduce the difficulty and cost of operation and maintenance, and keep the continuous investment of the project at a lower level.
In this way, it will also ensure that the later returns of the photovoltaic project will be higher.

　　In summary, high-power large components have better performance-to-price ratios in practical applications.
It significantly reduces the variable part of the project's boss cost, and it has the advantage of return on investment in later operation and maintenance.
All of this conforms to the requirement of parity grid for extreme control of power generation costs.
At present, the 210 components iterated from have more advantages in return on investment.

　　Therefore, it is time to lower the voice and return to the market for the debate over the two technical routes of 182 and 210.
Project investment income has given an answer to this debate, and both represent the direction of large silicon wafers and high power, and both will gain their own market share in the current and future development of the photovoltaic industry.
Let the technology belong to the technology and the market belong to the market, which is the correct and rational approach!
