Figure is as shown in Fig. 2, the determination method includes:
Step 201: obtaining the adjustment number in default date section.
Wherein, preset date section representative is time span to be studied, and default date section is remembered using year, month, day
It carries, is correspondingly arranged on and opens date and Close Date.
For example, the time span for presetting date section can be 1 year, from December 31 1 day to 2019 January in 2019
Day, adjustment number can be 4 times.
Step 202: establishing the adjustment periodic set including at least one adjustment period in default date section.
Wherein, each adjustment period includes at least one daily data item, adjustment angle, power generation effect in the period in the period
Rate.
It will be appreciated by persons skilled in the art that the unit of default date section is day, that is to say, that default date section packet
Containing multiple one days.And for presetting the adjustment periodic set in date section, then can exchange complete cycle according to actual needs includes
Number of days be defined, adjustment the period can be limited to one day or be limited to two days, a week can also be limited to,
It can certainly be limited to ten days etc..
In the adjustment periodic set established in default date section, the number of days in each adjustment period can be identical, example
For example one day.Since the adjustment period is a period, thus each adjustment period also has Start Date and Close Date.
For each adjustment period, each adjustment period includes at least one daily data item, wherein daily data
Item includes Time of Day (Year/Month/Day), bracket optimum angle of incidence and actual power efficiency.Herein, bracket optimum angle of incidence refers to
When same day bracket is configured with a certain fixed angle, under the fixed angle, photovoltaic module has optimal generating efficiency, should
Bracket optimum angle of incidence can be initial value with -20 °, in -20-90 ° of angular range, with it is micro be incremented by (such as every time increase
0.1 °) form recycle input in the calculation procedure of known bracket optimum angle of incidence, choose the maximum inclination angle conduct of generated energy

The difference adjusted between the number in period and adjustment number into adjustment periodic set is not more than 0.
Wherein, the first adjustment period and second adjustment period merge after power generation loss efficiency be to appoint in adjustment periodic set
The minimum value of power generation loss efficiency after the adjustment period merging on two adjacent dates of meaning, power generation loss efficiency is two adjacent days
Adjustment week after the sum of generating efficiency merges with the adjustment period on two adjacent dates in the adjustment respective period in period of phase
The difference of the generating efficiency of phase.
It will be appreciated by persons skilled in the art that on the one hand, since each adjustment period in adjustment periodic set is
It arranges sequentially in time, is by two adjacent days when adjusting the adjustment of number of cycles in being adjusted periodic set
The adjustment period of phase merges to realize；On the other hand, when the number and adjustment in the adjustment period in judgement adjustment periodic set
When difference between number is greater than 0, needing to exchange several or multiple adjustment periods in set complete cycle is adjusted, and is adjusted at this time
The number of days for being included in each adjustment period in gathering complete cycle is no longer identical.
In order to obtain the first adjustment period and second adjustment period, needs to carry out circulate operation in this step, will adjust
The adjustment period on all two adjacent date in periodic set merges, and by all merge after adjustment the period hair
Electric loss efficiency compares, to obtain the first adjustment period before the smallest merging of power generation loss efficiency and second adjustment week
Phase.
In addition, adjusting the angle in the corresponding period and also occurring after merging adjustment in several or multiple adjustment periods
Change, thus the generating efficiency day adjacent with the first two of merging in the adjustment period after the adjustment period merging on two adjacent dates
The adjustment period of phase the sum of generating efficiency within the respective period has differences.
For example, the first adjustment period is on January 1st, 2019, and the second adjustment period is on January 2nd, 2019, then the
The adjustment period after one adjustment period and the merging of second adjustment period is on January 1st, 2019 to January 2, due to the tune after merging
Complete cycle, duration changed, and adjusts the angle in the period and also changes, thus, on January 1st, 2019 and on January 2nd, 2019
The generating efficiency in this adjustment period of the sum of the generating efficiency in the two adjustment periods and on January 1st, 2019 to January 2
Difference is the adjustment week of the sum of the generating efficiency in adjustment period on the adjacent date of any two in 2019 with two adjacent dates
