Today, energy consumption in countries around the world, including Korea, is increasing every year, and greenhouse gas emissions from energy use are also rapidly increasing in proportion to energy consumption.

Therefore, the development of environmentally friendly alternative energy has long been a major concern in each country's energy retention policy, and the need and importance of alternative energy development is increasing in weight over the years.

In line with this, in recent years, energy technology development using solar energy, which is relatively pollution-free and relatively easy to secure the energy source, has been actively researched and used.

The solar energy is a technology for converting sunlight directly into electrical energy (photoelectric effect) and includes a solar cell module, a battery and an inverter. That is, through the above configuration it is possible to use unlimited clean energy sources using sunlight.

On the other hand, Korea was appointed as the compulsory country to control greenhouse gas emissions by joining the 47th in the United Nations Framework Convention on Climate Change held in Rio de Janeiro, Brazil in December 1993. .

The main purpose of the above-mentioned UN Framework Convention on Climate Change is that States Parties will endeavor to regulate and prevent global warming, which has been adopted by the Parties to determine standards for greenhouse gas emissions control by States Parties to implement this. 'to be.

Accordingly, in accordance with the Kyoto Protocol, Korea should reduce 5.2% of greenhouse gas emissions by 1990 by 2012. Accordingly, as a part of reducing greenhouse gas emissions, it is aimed at 100,000 households for residential solar power generation. Doing.

For such solar power generation for homes, structures and module clamps for installing solar cell modules are required, and the structures or module clamps described above are used for a long time of 20-30 years to stably install solar cell modules.
