Industrial and commercial roof photovoltaic, to see the case of more than 3 years!
Release time:2022/3/29 9:42:04      Clicks:1013

2022 is the first year of the outbreak of industrial and commercial distributed photovoltaic growth, and it has encountered a good historical opportunity. On the one hand, industrial and commercial electricity prices have risen, and the difference between peak and valley electricity prices has widened, resulting in an increase in factory operating costs. On the other hand, the local power limit production, forcing the factory to reduce energy consumption, photovoltaic is the only way out.


With the help of multiple factors, industrial and commercial rooftop distributed photovoltaic has become a trend, and a clear signal will start to break out in 2022, are you ready? To share with you some industrial and commercial rooftop photovoltaic cases.


Sewage treatment plants put on a "photovoltaic coat"

Cixi Citong sewage treatment plant covers an area of about 250,000 square meters, the average daily sewage treatment volume is 38,000 cubic meters, the total photovoltaic capacity of the current construction is 2.67 megawatts, can provide about 2.5 million degrees of green electricity per year, equivalent to planting 4730 trees, saving about 859 tons of standard coal, reduce carbon dioxide about 1600 tons, energy saving and emission reduction effect is significant. Compared with conventional rooftop distributed photovoltaics, the project adopts unconventional means such as latching and door frame to arrange photovoltaic assembly, overcoming problems such as large sewage treatment pool area and no erection support points, and effectively realizing the secondary development and utilization of land and space resources.


Photovoltaic + cold storage illuminates the road to poverty


Erlongkou Village, Zhuxiang Town, Rushan, Shandong Province, the village collective used poverty alleviation funds to build a new cold storage with a reserve of 150 tons. Unlike ordinary cold storage, there are blue solar photovoltaic panels on the roof of the warehouse.

As a photovoltaic poverty alleviation project, the cold storage roof photovoltaic power station has installed a total of 24 high-efficiency solar photovoltaic power generation panels, which can save 20% of the electricity cost of the cold air storage in a year. After the village has a cold storage photovoltaic power station, the villagers will store half of the grapes, postpone the listing for two or three months, and remove the storage costs of 4 cents per catty, and the income can double!


Industrial and commercial power stations that pay back more than three years


The distributed photovoltaic project undertaken by HHI Electric Group in Shanghai Port Machinery Heavy Industry was accepted and put into operation by Shanghai Electric Power Company in March 2017.

As of May last year, the power station has been in stable operation for 39 months, and the cumulative recovery of funds has exceeded the project construction cost, successfully realizing the full recovery of construction costs, and also saving a lot of electricity for the production base. The design life of the project is 25 years, and in the next 261 months, it will continue to produce economic and environmental benefits.

The project income adopts the mode of "self-use, surplus electricity online" to ensure the effective use of electricity. The actual power generation of the project exceeds the design value by 12%, the power consumption of the factory is large, and the project has also obtained the corresponding clean energy subsidies from the government, speeding up the recovery of construction costs, and the investment payback period is 1-2 years shorter than that of similar projects in the market.

The total installed capacity of the project is 2.4 MW, and the power station produces 8.06 million KWH of electricity, which is equivalent to the production electricity consumption of the plant for one year, and can reduce the use of 2,579 tons of standard coal, 8035 tons of carbon dioxide emissions, and 241 tons of sulfur dioxide emissions.
