15. The pv power generation control method according to claim 14, wherein if the primary index is not met, the blade device (10) is in standby and not operated, and if the secondary index is not met, the blade driving device drives the blade device to fold.
16. The photovoltaic power generation control method according to claim 12, wherein the executing of the manual driving switch includes polling a manual control command, determining whether the driving switch executes the blade component deployment, and if so, the blade control device (10) controls the blade driving device to perform the photovoltaic blade (1) deployment operation; if not, whether the blade assembly folding is executed by the driving switch or not is judged, if yes, the blade driving device drives the blade assembly to fold, and if not, the blade control device (10) controls the blade driving device to be in standby and not to act.
