While the OFFICE of President remains in highest regard at NewEnergyNews, this administration's position on climate change makes it impossible to regard THIS president with respect. Below is the NewEnergyNews theme song until 2020.

    BRAZIL FLOATS BIG SOLAR

    Brazil Announces Huge 350 MW Floating Solar Power Plant

    Anand Upadhyay, April 6, 2015 (CleanTechnica)

    “Brazil’s energy ministry…[ranks hydropower as its top energy option], followed by wind power and biomass (mostly bagasse)…[but] the country has been reeling under its worst drought in 80 years. The Cantareira reservoir system, which serves more than nine million people in the state, is only 5% full. At the Alto Tietê reservoir network, which supplies three million people in greater Sao Paulo (South America’s largest city), water levels are below 15%...A number of cities have taken to water rationing…[E]nergy crises could be next...Last year, Brazil’s National Electric Energy Agency (ANEEL)…[provided] 20-year PPAs to companies that will invest over $1.66 billion in 1,048 MW of solar power spread over 31 solar parks. Power production is expected to start by 2017. The country has now decided to further push solar energy…[through] a series of pilot tests of floating solar power plants on hydroelectric dam reservoirs within a period of four months…[The electricity] is expected to cost between approximately $69 and $77 per MWh…” click here for more

    Floating solar power systems are wonderful ideas for Brazil. And it’s very important to maintain effectively same direction and position on the water for floating solar plants. Because directional change of solar panels reduces electricity production. So floating solar plants also need the directional control mooring systems for their parked positions. Azimuth and position change of floating solar plants caused by wind, waves and external forces. Restoring Force Strengthened Mooring System for floating solar plants has been created in South Korea. This Mooring System generates Restoring Force immediately when floating solar plants are being rotated or moved on the water.

    In addition, you have to reduce vibration to install floating solar plants. Because, it can make micro-cracks to floating solar panels and the durability problem of floating solar plants. The risk of power loss in PV modules due to micro cracks is increasing.

    Vibrations caused by wind, waves and external forces. New Type Floating Body Stabilizer has been created in South Korea. The Floating Body Stabilizers generate drag force immediately when floating solar plants are being rolled, pitched and yawed on the water.

    Recently, Restoring Force Strengthened Mooring Systems and Floating Body Stabilizers have been used for floating solar plants in South Korea.

    You can see them in Ochang Dam natural reservoir, South Korea. I N I WORLD
