Alcoa New Technology Reduces Solar Energy Costs

The project is part of the US Department of Energy's 2.1 million U.S. aid program.

Current solar cells use glass mirrors attached to steel or aluminum structures to receive and collect solar energy, which is then converted into heat energy.

The United States has replaced glass mirrors with a combination of aluminum plates with a high-reflective coated parabolic mirror that has been designed into a single structure to form a new CSP parabolic trough system.

Due to the low installation cost, it is expected that the parabolic mirror of all-aluminum structures will reduce solar energy use costs by 20%.

Solar collectors are planned to be made from recycled materials.

It is expected that the test results will be seen in the second quarter of 2010, and then the system will enter a larger level of large-scale trials.

US executives said that the company plans to put aluminum alloy solar cells into mass production in the next two to three years.

The company's ultimate goal is to make CPS a brand with a national competitiveness.

The United States has always been known around the world for its strategy of sustainable development. We wish them every success in this creativity.
