  Embodiments of the present invention will be described below with reference to the drawings. However, such embodiments do not limit the technical scope of the present invention.

<Embodiment 1>
FIG. 1 is a configuration diagram of an embodiment of a used solar cell price calculation system to which the present invention is applied. A used price calculation system 1 in the figure is a system to which the present invention is applied, and a computer calculates a used price of a used solar cell using information input from an input terminal and a stored database.

  As shown in FIG. 1, the used price calculation system 1 includes a computer 2, an input terminal 3, a database 4 stored in the computer 2, and the like. The computer 2 compares the information input from the input terminal 3 with the stored database 4, derives a price calculation parameter that is a parameter used for calculating a used price, and calculates a used price using the price calculation parameter have. Specifically, the price calculation parameters are “unit price of W”, “rated value”, “coefficient of elapsed years”, “deterioration rate”, and the like.

  The input terminal 3 has a function of inputting information to the computer 2, and used product information, which is information necessary for calculating used prices, is input from this terminal. The used product information is specifically the manufacturer name / model of the used solar cell, the number of years since installation, the installation area, and the like.

  The database 4 is a database stored in the computer 2 and holds various databases necessary for calculating used prices. Various databases necessary for calculating used prices are referred to as possessed DBs, and specifically, a unit price DB, a rated value DB, an expected life DB, a weather data DB, a deterioration rate DB, and the like.

  The unit price DB, which is one of the above-mentioned DBs, is generally used in the current market for each type of solar cell such as single crystal, polycrystal, amorphous, or laminated type classified by manufacturer name / model. The average price per unit power generation recognized is registered.

  In the rated value DB, which is one of the possessed DBs, output characteristics of new solar cells are registered for each manufacturer name and model.

  In the expected life DB, which is one of the possessed DBs, the expected life when the solar cell is new is registered for each manufacturer name and model.

  In the weather data DB, which is one of the possessed DBs, the accumulated solar radiation amount and the average temperature of the Japan Meteorological Agency AMeDAS are registered for each region.

  The degradation rate DB, which is one of the possessed DBs, includes solar cells corresponding to the number of years elapsed for each type of solar cell, such as single crystal, polycrystal, amorphous, or stacked type, classified by manufacturer name / model. The output decrease rate for each type, the output decrease rate due to the integrated solar radiation amount and the average temperature, the output decrease rate due to the degree of salt damage, etc. for each installation area are registered.

  The “unit price of W”, which is one of the price calculation parameters, is derived by referring to the unit price DB held by the database 4 using the manufacturer name / model of the used product information input from the input terminal 3.

  The “rated value” which is one of the price calculation parameters is derived by referring to the rated value DB held by the database 4 using the manufacturer name / model of the used product information input from the input terminal 3.

  The “elapsed years coefficient” that is one of the price calculation parameters is the expected life DB held by the database 4 using the manufacturer name and model of used product information input from the input terminal 3 and the elapsed years after installation. Reference is made as a ratio of the expected life of the used solar cell to the expected life of a value obtained by subtracting the number of years since installation.

  The “deterioration rate” which is one of the price calculation parameters is the weather data stored in the database 4 using the manufacturer name / model of the used product information input from the input terminal 3, the number of years since installation, and the installation area. Derived with reference to DB and deterioration rate DB.

  In particular, it is preferable to derive the “deterioration rate” individually from the data of the location, the installation position, the installation angle, the installation period, and the weather data for each region because a more accurate value can be obtained.

  This used price calculation system 1 calculates the used price of a used solar cell by the calculation formula “unit price” × “rated value” × “elapsed years coefficient” × “deterioration rate” using the derived price calculation parameters. calculate.

  As an example, trial calculation is performed by applying specific numerical values to the above formula. First, regarding the “deterioration rate”, the output decrease rate over time according to the type of solar cell is 10%, the output decrease rate due to the integrated solar radiation amount and the average temperature is 10%, and the output decrease rate due to the degree of salt damage, etc. is 0%. In this case, 0.81 is derived from the formula: 0.9 × 0.9 × 1.

  Next, regarding the “elapsed years coefficient”, when the expected life is 20 years and the elapsed years after installation is 10 years, 0.5 is derived from the formula: (20−10) / 20.

  Of course, the “elapsed age coefficient” may be derived using a constant reduction rate corresponding to the elapsed years after installation without using the expected life.

  Furthermore, when “unit price of W” is “200 yen / W” and “rated value” is “100 W”, these numerical values are applied to the above formula, and the formula: 200 × 100 × 0.5 × 0. From 81, 8100 yen is calculated.

  FIG. 2 is a diagram illustrating an example of a processing flow when the used price is calculated in the used price calculation system 1.

  First, used product information, which is information necessary for calculating the used price of a used solar battery, is input to the computer 2 from the input terminal 3 (S201).

  The computer 2 receives the used product information and refers to the possessed DB of the database 4 stored therein (S202).

  The computer 2 refers to the possessed DB and derives a price calculation parameter used for calculating a used price (S203).

  The computer 2 calculates a used price using the price calculation parameter (S204).

  As described above, the used price calculation system 1 can more accurately calculate the used price of a solar cell having a unique concept such as a unit price of W or a deterioration rate as a price determining factor.
