Tracking bracket VS fixed bracket which benefit is higher in 25 years
Tracking bracket VS fixed bracket which benefit is higher in 25 years
Since the cost of the bracket in the entire system is relatively small, and at the same time, it is restricted by traditional concepts and feels that its technical content is also low. Therefore, during the construction of photovoltaic power stations, solar photovoltaic brackets are often in an awkward state of "out of favor".
As everyone knows, with the maturity of China's photovoltaic market and the continuous improvement of technology, brackets not only play a simple supporting role in the entire power station, but can also greatly increase power generation and reduce basic costs.
As we all know, the brackets in the current market are mainly divided into two categories, fixed PV mounting structure brackets and tracking brackets.
Tracking bracket PK fixed bracket basic cost
According to the local geographical environment, the fixed support 1MWp covers an area of 20.50 acres, arranged according to 23*2, the number of 1MWp foundation pipe piles is 460, the large-span tracking support 1MWp covers an area of 23.5 acres, and the number of 1MWp foundation pipe piles is 176 One, the total cost difference between the fixed bracket and the long-span tracking (5° inclination) is 0.034 yuan/W.
Cost recovery period
The universal PVSYST photovoltaic simulation software imports local weather data, and the tracking bracket (5° inclination angle) increases the power generation by 10% compared with the fixed bracket. After calculation, the fixed bracket 1MWp annual power generation is 1081157 degrees, and the large-span tracking bracket (5° inclination angle) ) The annual power generation of 1MWp is 1,189,273 degrees, and the long-span tracking bracket (5° inclination) is relative to the fixed increase in investment and the partial payback formula:
Combined with the data of a project site in Anhui, the project capacity is 1MWp, and the recovery period is calculated as follows:
That is, the large-span tracking bracket increases the investment part relative to the fixed bracket, and the cost can be recovered after 0.4 years!
Increase annual income
The ultimate goal of the intelligent tracking system is to help photovoltaic power plants generate efficient power generation and increase revenue. Then how to calculate the increased revenue of the power station, and see as follows:
Taking a project site in Anhui as an example, with 1MWp capacity as the calculation basis, the local on-grid electricity price is 0.85 yuan/kWh:
Years: 1-10 years
(1189273-1081157)*0.94*0.85*(10-0.4)=829,293 yuan
Years: 11-15 years
(1189273-1081157)*0.89*0.85*(15-10)=408,948.8 yuan
Years: 16-20 years
(1189273-1081157)*0.86*0.85*(20-15)=395,164 yuan
Years: 21-25 years
(1189273-1081157)*0.83*0.85*(25-20)=381, 379.2 yuan
summary report
In summary, the normal operation of photovoltaic power plants for 25 years, 1MWp long-span single-axis tracking (5° inclination) can increase revenue by more than 2.01 million relative to fixed brackets, and 10MWp can increase revenue by as much as 20.15 million!
