Parking lots can be found everywhere, there are factories, new energy charging stations, shopping 

malls and scenic areas, etc., these places have parking lots or parking sheds, at first heard that the 

solar photovoltaic carport can generate electricity, very actively want to understand it, but the cost 

of solar photovoltaic carport dissuaded a lot of people, so many people will be puzzled, the cost of 

solar photovoltaic carport is so high, you can recoup the cost of the carport? In fact, if you want to 

know this question, then you must first know the profit model of solar photovoltaic carport.

Solar photovoltaic carport profit model

Mode one: grid-connected selling point

Many places do not consume a lot of electricity, so the installation of solar parking shed electricity generated 

by no place to consume, can only be sold on the grid to the grid, this pure grid sales of electricity recovery cost 

cycle is the longest, generally about nine years can be back to the capital.

Mode two: self-generated, surplus power on-line

There are also many places that need to use a lot of electricity every day, such as factories, new energy charging

 stations, etc. If it is in accordance with the residents of electricity, more than 50 cents for one unit of electricity, 

if it is a commercial electricity, the price is higher; general payback cycle of about five or six years.

An example to explain the self-generated self-consumption of surplus power on-line mode: a solar PV carport a 

day sent 200 degrees of electricity, factories or charging stations a day with 400 degrees of electricity, then only 

need to pay 200 degrees of electricity; a solar PV carport a day sent 500 degrees of electricity, factories or charging 

stations a day with 400 degrees of electricity, then not only don't need to pay for electricity, but also have 100 degrees 

of income from electricity, this 100 degrees of electricity is the price of selling electricity according to the grid, 

not residential electricity or commercial electricity.
