摘要:
There is provided a system control method which reduces maximum energy consumption in a tracking-type photovoltaic power generation system having a plurality of tracking-type photovoltaic power generation devices and reduces energy supply capacity. An integrated control part drives driving parts in each of tracking-type photovoltaic power generation devices at predetermined time intervals and drives the driving parts at different times, which can disperse temporally the large energy consumed at the time of activation of the driving parts in the tracking-type photovoltaic power generation devices, thereby reducing the energy supply capacity.

Provided is a mercury-free vehicle discharge lamp that is stably lighted with a power of 18 to 30 W in a steady time. The lamp is defined in a light-emitting portion (11). A discharge medium including a metal halogen compound and a rare gas are sealed into the lamp. The lamp also has a discharge space in which electrodes (32) are disposed and satisfies the following equation. −40≦(a−35)×5.5+(x−13.5)×10+(1.85−t)×100+(2.5−d)×100≦40 where, a power [W] supplied in a stable lighting time and having a value of 18 or more 30 or less x: pressure [atm] of the rare gas sealed into the discharge space t: thickness [mm] of the region where the radical thickness of the light-emitting portion becomes maximum d: inner diameter [mm] of the region where the radical thickness of the light-emitting portion becomes maximum
