Abstract:
PURPOSE: An apparatus for controlling a MPPT(Maximum Power Point Tracking) invertors in a photovoltaic generation system is provided to eliminate the degradation of a MPPT function due to the temperature difference between sectors by successively cooling each sector in a photovoltaic generation array. CONSTITUTION: A temperature compensation sensor(24) is respectively installed in a plurality of photovoltaic generation array sectors which partitions a photovoltaic generation array by section. The temperature compensation sensor senses temperature change in the photovoltaic generation array sector in response of cooling water injection. A temperature compensation circuit(26) generates a temperature value which is compensated as a temperature signal transmitted from the temperature compensation sensor. A MPP(Maximum Power Point Tracking) inverter(10) corrects an temperature detection error at a current maximum power point tracking operation by referring to a temperature value corrected in the temperature compensation circuit. The temperature compensation circuit generates a mean value of the temperature signal into the temperature value corrected.

PURPOSE: Efficiency enhancement equipment for photovoltaic facilities is provided so that a cooling water jetting unit sprays the cooling water while traveling back and forth and rotating to uniformly spray the cooling water on the front side of a photovoltaic module. CONSTITUTION: Efficiency enhancement equipment for photovoltaic facilities comprises a cooling water storing tank(1), a cooling water jetting unit(6), a cooling water supply pipe(5), a pump(25), two or more valves(21,22,23,24) and a controller(3). While traveling back and forth and rotating, the cooling water jetting unit sprays the impinging jet of cooling water to photovoltaic modules(7). The cooling water supply pipe supplies the cooling water to the cooling water jetting unit. The pump pumps the cooling water in the storing tank and supplies to the cooling water supply pipe. The two or more valves divide the photovoltaic modules into two or more sectors. The valves control the opening and closing of the cooling water supply pipe which is connected to the jetting unit corresponding to the photovoltaic modules in each sector. The controller opens the two or more valves in sequence to supply the cooling water to the photovoltaic module in each sector.
