It is temporarily stored in collective's generated energy information is transferred to data temporary storage module by controller；The data analysis unit is used
In obtaining collective's generated energy information from data temporary storage module automatically, the data analysis unit is for binding time information to collective
Generated energy information does following processing, and specific processing step is as follows:
Step 1: temporal information is labeled as Wi, i=1...n；Wi is real-time time letter when photovoltaic panel matrix starts power generation
Breath；Several collective's generated energy information of the power generation of photovoltaic panel matrix as time goes by are formed into collective's generated energy information group Hi, i
=1...n；Hi and Wi is corresponded；
Step 2: formula is utilizedI=x...n；X is preset value；Generating efficiency information group Vi, i is calculated
=x...n；
Step 3: Vi is determined；
S1: when Vi is more than or equal to preset value Vy, systems stay generates electricity；
S2: when Vi is less than preset value Vy, indicate that current collective's generated energy information already below certain efficiency, illustrates this
When the most strong direction of sunlight have occurred and that change；System generates conversion signal.
