Description

Building integrated solar power roof {BUILDING INTERGRATED SOLAR GENERATION ROOF}

Various embodiments of the present invention relate to a building-integrated solar power roof that can facilitate maintenance using a transparent scaffold.

Recently, interest in solar power generation as an alternative energy source according to the depletion of resources is increasing. Solar power generation is an integrated technology that converts sunlight incident on the earth into electrical energy. Not only is it environmentally friendly, but once the device is installed and operated, even if there is no separate energy input, if only the sun exists, electricity (eg voltage) and current), so its application range is gradually expanding.

In general, photovoltaic power generation consists of a photovoltaic module including a photovoltaic cell, the photovoltaic cell is electrically connected by a cable, and the photovoltaic module is operated by being connected in series or in parallel. The photovoltaic module has been most commonly used from the past to the present in order to be applied to a building. For example, the photovoltaic module is disposed on the roof of an existing building. In addition, the solar module may include a film or protective glass for protecting the solar cell from the external environment.

For example, the lighting element 206 may be turned on or off at an interval of 1 second by the oscillator 204 and the ON/OFF switch 205 .

In this way, by configuring the lighting element 32 of the plurality of lighting devices 30 to turn on or blink by receiving power generated from the plurality of solar modules 30 on the transparent scaffolding 90, the lighting element ( 320 is turned on by receiving power produced during power generation of a plurality of photovoltaic modules 30 or flickering by the oscillator 204 and the ON/OFF switch 205 to improve the visibility of the product This allows you to quickly check whether the product is faulty or not. Accordingly, it is possible to more easily inspect and maintain the product.

In addition, the first and second bypass diodes 201 and 202 are double connected to a junction box (not shown) by a cable, so that current when the first and second bypass diodes 201 and 202 are used for a long period of time. When one bypass diode (eg, the first bypass diode) fails, the other bypass diode (eg, the second bypass diode) operates, thereby preventing product degradation due to the failure of one bypass diode. have.
