Description
The present invention relates to a solar power generation system leasing business method, and more particularly, to a solar power generation system leasing method in which a solar power generation system is leased to a customer having high power consumption, thereby reducing the total power consumption cost, And business methods for pursuing economic benefits through countervailing transactions.
Electricity is an indispensable resource for modern people. In particular, in the summer when the temperature rises, power consumption increases due to cooling demand. In addition, electrical appliances used in homes and industries use electricity. These electric appliances are the civilizations that give convenience of life.
However, such power is generated using fossil energy or nuclear power. However, the problem of safety of nuclear power, which is known as cheap energy in recent years, has become a global issue for environmentally friendly energy production.
Recently, there is a campaign to save electric energy through power saving rather than renewing the power plant.
In addition, Korea Electric Power Corporation (KEPCO) is attempting to raise electricity costs in order to raise the price of energy sources and to reduce electricity consumption. In order to prevent the use of electricity, which is a property of the public nature, by a certain person, progressive rates are applied by setting a section for each usage amount.
For example, if an electric charge of about 200 won per kW is set up for 100kW, 400 won per kW for 100kW to 200kW, and 800 won for 1kW between 200kW and 300kW. Therefore, if electricity is used twice as much as usual, the cost of electric power may be four times or more higher than usual.
In such a manner that a progressive section is provided to set an electric charge, a large amount of electricity can be saved if electricity can be avoided from the progressive section. In this regard, a new business model can be proposed.
In addition, recently, KEPCO is going to set the electricity cost by dividing it by the peak time of power load and season, or by time and season with low power load. Therefore, businesses that produce photovoltaic electricity in the time of low power load or season, store it in energy storage device (ESS), or sell or sell the power by peak time and season by way of grid connection are studied have. There is a need for a way to more easily apply and disseminate such business.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a flowchart of a solar power system leasing method according to an embodiment of the present invention.
2 is a flowchart of a solar power system leasing method according to another embodiment of the present invention;
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. , Thereby not limiting the spirit and scope of the present invention.
Before describing the embodiments of the present invention, terms are defined.
a) Lease: The 'lease' described in this embodiment means contracting with the customer and leasing equipment (solar power system). In addition, an installment contract to pay a certain amount of monthly sales to a customer while the ownership of the equipment is owned by the customer is also included in the "lease". In addition, "ownership" is included in "lease" if the ownership belongs to the investor or the management operator. It also includes cases where customers, operators, and investors have joint ownership of the equipment.
b) Photovoltaic power generation system: The 'photovoltaic power generation system' described in this embodiment means a device that produces electricity using a solar power facility. The 'photovoltaic power generation system' of this embodiment is composed of equipment such as a solar module, an inverter, and a structure.
1 is a flowchart of a solar power system leasing method according to an embodiment of the present invention.
S11 is a step of calculating the difference between the past monthly electricity cost of the customer and the estimated monthly electricity cost predicted when the solar power system is installed, and S12 is a step of comparing the difference with the lease amount of the photovoltaic power generation system.
Table 1 below shows the electricity used by the customer each month over the past year and the corresponding electricity bill. One specific example is the progressive electricity fee calculation method of KEPCO's residential electricity bill. That is, the more electric power is used, the more electric power is arithmetically increased in proportion to the electric power, but the more expensive electric power is generated in a certain section.
That is, as shown in the following Table 1, when electricity is used for 600 kW per month, electric power charges for 210 kW, 700 kW and 290 kW are generated, respectively.
In the case of homes and businesses, there are electric appliances that are basically used, such as refrigerators and TVs. As shown in Table 1, electricity of 600kW or more is used every month even if there is a slight increase or decrease every month. Especially in the summer, as the air conditioner usage increases, the electricity cost will be used up to 800kW. Therefore, in summer, it is required to pay an electricity fee of 160,000 won more than winter.
When the customer uses the electricity shown in Table 1 and installs the solar power generation system with the capacity of 3 kW capacity, the estimated monthly electricity cost is as shown in Table 2 below. When a photovoltaic power generation system with a power generation capacity of 3 kW is installed, the electricity consumption of 300 kW is reduced as compared with the electricity quantity normally used.
If a solar power generation system with a generating capacity of 3 kW per month is installed, it is possible to avoid the progressive section of the electricity charge. In this case, the electricity cost savings in many months of electricity use is even greater. Table 3 below shows the difference in the past monthly electricity charges minus the estimated monthly electricity charges in Table 2.
That is, as shown in Table 3, when a customer installs a photovoltaic power generation device, the customer can save over 150,000 won of electricity each month, and in particular, in August and September, the electricity cost of 250,000 won can be saved.
Assuming that the monthly rent of the photovoltaic power generation equipment is 100,000 won, the cost that the customer can save purely is shown in Table 4 below. Particularly, in the business method of the present invention, the installation and maintenance of the photovoltaic device are all free of charge.
As shown in Table 4, even if the monthly rent of the solar power system is 100,000 won, the customer actually saves the electricity cost of 100,000 won or more on average per month, and the electricity cost of about 1,220,000 won per year can be saved.
The process of S11 is calculated automatically by the application program stored in the computer, and is calculated by inputting the monthly electricity usage amount of the customer and the capacity of the solar power generation system to be leased. In addition, the application program calculates the expected monthly electricity charge and the difference based on the electricity charge progression interval table.
The embodiments of Tables 1 to 4 above are examples for easy understanding of the technical principles of the present invention and do not accurately apply the progressivity or electric charge system according to the current usage amount of KEPCO. This point should be referred to in understanding the present invention.
The step S13 includes a step of making a suitability judgment when the difference is larger than the lease amount and making a nonconformity judgment when the difference amount is less than the lease amount.
For example, if a customer leases a PV system over a one-year period, adding the rent and electricity costs will benefit the customer if the difference is positive. These customers will be able to lease solar power systems. These customers usually use monthly electricity more often than not. Customers who use electricity in areas where the progression rate is low may be negative.
S14 is a stage in which the photovoltaic power generation system is installed in a customer whose difference is larger than the lease fee. In other words, the solar power generation system can be installed in the customer who has been judged as conforming.
On the other hand, businesses that lease photovoltaic power generation systems will lose operating profit even if they finance leasing, finance costs, solar power system maintenance costs, and purchase costs.
As described above, when the photovoltaic power generation system of the present invention is used, the monthly electricity cost is low enough for the customer to pay the lease fee. In addition, business entities that lease solar power generation systems can profit from leasing. In addition, countries can reduce the burden of installing new power plants because they can supply solar energy, which is environmentally friendly renewable energy, throughout the country.
In particular, as the cumulative deficit of Korea Electric Power Corporation (KEPCO) is increasing due to the difficulty in raising tariffs on electricity as a public good, such a business method is a milestone. In addition, the supply speed is expected to increase sharply because it installs and maintains solar power generation system without the initial capital to the customer.
On the other hand, it is possible to consider a business that generates profit by using the solar power generation system of the present invention. That is, when the photovoltaic generation system of the present invention is installed at a specific position, a profit that is enough to cover the rent is generated. This allows the business entity to benefit from the lease, and anyone who uses the photovoltaic system can profit from the lease payments, so that the PV system can be positively installed at a desired location. As a result, the production of photovoltaic electricity, which is environmentally friendly renewable energy, will be promoted.
Data on weather and temperature are recorded in national agencies such as the Korea Meteorological Administration and can be used to predict annual solar irradiance for specific areas. If such a solar irradiation amount is predicted, it is possible to predict the amount of electric power to be produced when a certain type of solar power generation system is installed. Businesses that produce electricity through solar power, sell it, or trade offsets are getting more and more affordable because electricity costs rise year by year and electricity fees differ by power peak time and season, The important thing is the return on investment.
2 is a flowchart of a solar power system leasing method according to another embodiment of the present invention.
S21 is a step of inputting the solar irradiation amount data at a specific place where the solar power generation system will be installed into the calculation system.
As mentioned earlier, the solar irradiance for a specific area is recorded over the years by the Meteorological Agency or other agencies, and the average solar irradiance for that region is predicted. If the customer relies on the return rate of the place where the PV system will be installed, obtain the solar irradiation data of the place to be installed from the Meteorological Agency or a reliable institution.
The 'output system' is a kind of program that predicts the amount of power generated when a PV system is installed in a certain place, and then sells it to KEPCO or other agencies based on this forecast, or forecasts the revenue generated through countercurrent transactions.
That is, in step S21, when the customer gives information on a specific place and area, it acquires solar irradiation amount data of the place and inputs it to the calculation system.
Step S22 is a step of estimating the amount of power to be produced for a predetermined period of time when the calculation system is provided with the solar power generation system in the specific place based on the solar irradiation data. When the capacity of the photovoltaic system is selected, the area of the place where the photovoltaic system is to be installed, and the photovoltaic dose data set, the amount of power to be produced in the photovoltaic power generation system can be predicted.
On the other hand, when the produced electric power is stored in the energy storage device (ESS), the stored electric power amount can be predicted. Typically, when about 100 power is produced, only about 50 energy is stored in the energy storage device and the remaining 50 is lost during storage. Even so, it would be advantageous if the power consumption could be resold or counterbalanced the electrical energy stored at peak times. Therefore, the calculation system can simultaneously calculate the electric power to be produced based on the solar irradiation data and the amount of electric power to be stored when storing it in the energy storage device.
S23 is a step of calculating a profit generated when the calculation system sells the electric power produced by the solar power generation system or performs an offset transaction.
The generated electricity can be sold to KEPCO or another institution or canceled. They can sell electricity, trade offsets immediately after they are produced, store them in energy storage (ESS), sell them by power peak hours, seasonally, or offset them. The electricity that is sold here or the countervailing transaction can be converted into money.
By setting a time period in the output system, the amount of power to be produced during the period and the corresponding revenue can be accurately calculated.
S24 is a step of comparing the profit with the rent of the photovoltaic power generation system to determine whether the photovoltaic power generation system is installed or not.
When a user installs a photovoltaic system on a lease basis, monthly or specific time-based costs are incurred. For example, let's assume that you will incur costs of about 100,000 won per month. At this time, the output system can calculate the profit obtained by selling the electric power produced by the solar power generation system or by performing the offsetting transaction. If the electricity generated by the solar power system is sold for a month or if the counterparty transaction generates a profit of 150,000 won, the net profit of 50,000 won per month will be generated even if the rent of 100,000 won is paid. This will give you enough motivation to operate the PV system in your area.
Companies offering equipment for photovoltaic systems can receive monthly rent payments of 100,000 won, and those who install photovoltaic power generation systems can earn 50,000 won per month by utilizing existing space. In addition, the country does not need to build new power plants. Solar power is environmentally friendly renewable energy.
Such a solar power generation system may be installed in an individual home, or may be formed as a large-scale industrial use.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Modifications and additions by those skilled in the art to an equivalent range based on the embodiments will also fall within the scope of the present invention.
