The present invention relates to a photovoltaic power generation system combined with photovoltaic modules of various sizes.

More specifically, in the process of replacing a single-sided solar panel with a double-sided panel, the previously installed pillars and the main frame are not removed, but the height of the double-sided panel is adjusted by combining the expansion frame so that the main frame is extended. Accordingly, the present invention relates to a photovoltaic power generation system combined with photovoltaic modules of various sizes capable of increasing heat collection efficiency by securing a separation distance between structures and coupling a reflector to a column.

As the price of oil soared, and air pollution caused by the depletion of fossil energy resources and excessive use of them became a serious problem, the use of alternative energy began to gain attention as part of the countermeasure.

One of the various application methods is to use solar heat, which is an infinite pollution-free energy source, and it is applied in various fields such as solar structures for electric energy production, solar power plants, solar boilers, solar vehicles, and solar houses.

However, in the conventional reflective focused solar power generation apparatus, the solar panel 10 is disposed only on the upper side, and the solar panel 10 is disposed on the upper side to utilize a reflector so that more sunlight is focused, the solar cell panel ( When 10) is installed on the lower side and configured on both sides, the solar cell panel 10 located at the lower side has a problem in that the power generation performance is not greatly improved due to low heat collection efficiency.

In addition, in order to focus more sunlight into the solar panel 10, a panel side reflecting unit 30 must be separately installed at the edge of the solar panel 10, and reflected from the panel side reflecting unit 30. Since the spaced reflector 40 for re-reflecting the generated light back to the solar panel 10 must be separately installed, it is not possible to install in a narrow place due to an increase in the installation area, and a limited place for the solar structure to be installed. There is a problem in that the collection performance cannot be maintained to the maximum by limited to
