For many pool owners, taking a variety of leaves, insects and other foliage that find their way into the water can be a spending of their time in the backyard. Enter smart Solar Powered Pool Skimmer, which not only took an elbow oil out of the pool to keep shining, but as his name, added bonus that is powered by the sun.
(in Olmedilla de Alarcón, Spain, 60 MW) Finished in September 2008. This power plant uses 162,000 average photovoltaic solar panel to deliver 60 MW of electricity on a sunny day. The whole factory was completed in 15 months at a cost of about 530 million U.S. dollars current exchange rate. Olmedilla built with conventional solar panels, which are made with silicon and tend to heavy and expensive.
(Spain, 50 MW) in 2008 Renovalia develop the power station in Puertollano, Ciudad Real, residential energy parks with an installed capacity of 50 megawatts (MW). The power generated here is equivalent to the annual domestic consumption of electricity of about 39,000 households. The energy produced here will replace the theoretical disposal 84,000 tons CO2/year or 2.1 million tons of CO2 over 25 years during the production.
(Portugal, 46 MW) Completed December 2008. This solar power plant is placed in the municipality of Moura, Alentejo, Portugal, one of the sunniest areas in Europe and besides one of the most economically depressed. The construction involves two stages, first with a built in 13 months and completed in 2008, and the rest will be completed in 2010, with a total cost of € 250 million for the project. The power plant will have an installed capacity of 46 mwp, by more than 376,000 solar panels. Nearly 190,000 panels (32 MW) installed in permanent structures, 52,000 (10 MW) in a single-axis trackers, which follow the sun in the sky, and further 20 MW of power capacity will be added during phase 2 project. This will occupy an area of 320 hectares (130 acres), producing 88 GWh of electricity per year.
(Germany, 40 MW) 550,000 First Solar thin-film CdTe modules. Completed in December 2008 Waldpolenz Solar Park, which is the world’s largest thin-film photovoltaic (PV) power system, built at a military air base east of Leipzig in Germany. The power plant 40-megawatt solar power system using state-of-the-art thin film technology. 550,000 First Solar thin film modules are used, which supplies 40,000 MWh of electricity per year. The investment costs for solar parks Waldpolenz Euro 130 million.
(Spain, 36 MW). Completed in October 2008, power plant that produces 34 GWh per year, which would own 12,000 households and prevent 375,000 tons of CO2. Facilities in seven acres and 172,000 panels houses. Project budget of about € 180,000,000. La Rioja, a region of Spain known for its wine, already covers 62% of electricity with enhanced resources.
Solar electricity generator with a capacity of 2 GW may be far from our imagination, but not in China. First Solar Inc., A solar power company from the United States, will build the solar electricity generator in Ordos city, in the province of Inner Mongol. This project is the development of the world’s largest solar electricity generator. The signing between them have been done at September 8, 2009 at the headquarters of First Solar Inc. in Tempe, Arizona, witnessed by Wu Bangguo, Chairman of the Standing Committee of the National People’s Congress.
“We are proud of the signing of this MoU” said Mike Ahearn, chief executive of First Solar Inc. was quoted as saying by APP.
Government of the United States and China can work together to reduce the cost of electricity from solar electricity generator connected to the network which will be competitive with electricity from traditional energy sources and create a blueprint for accelerating large-scale development of solar energy utilization of the world to prevent / reduce the impact of climate change, he added.
The MOU underscores a long-term partnership between First Solar Inc. and Ordos City, which First Solar Inc. will also consider making investments in the Ordos solar cells.
“We are very pleased to partner with one of the major players in industry of solar electricity generator technology in the project that will impact on low-carbon production in the Ordos.” said Cao Zhichen, deputy mayor of Ordos. For this project the Government of Ordos city will provide 65 square kilometers of land.
“Discussions with First Solar Inc. on the construction of the factory in China is a demonstration for investors in China that they can be confident of investing in high technology fields,” he said further.
China actively increasing the production capacity of electricity cheaper than solar energy sources as part of its national goal to achieve 10 percent energy supply from renewable energy sources by 2010 and 15 percent in the year 2020 including the energy source of wind, hydro, biomass and solar.
Currently, the installed capacity of solar electricity generator in China around 90 MW. Government of China plans to boost the utilization of solar energy from the initial target of just 1.8 GW in 2020 to 2 GW by 2011 and 10 to 20 GW by 2020 as announced in a press conference of the MoU signing.
The first phase of Ordos city solar electricity generator is building 30 MW of project demonstration is planned to begin in June 2010. The next phase, respectively built solar electricity generator with a capacity of 100 MW and 870 MW is expected to be completed by the end of 2014. While the last phase of 1000 MW will be completed by the end of 2019.
Based on the MoU, during the initial phase of implementation, First Solar Inc. will actively study the possibility of development module and manufacturing suppliers in the Ordos. First Solar Inc. also plans to expand its supply chain for the production of thin-film photovoltaic modules and used module recycling.
Solar technologies is now highly developed, with some progress is being developed to be used every day.
Below 10 Solar Technologies to note:
Solar-powered water pumps are an effective alternative to conventional gas or electric pumps. Modern pumps are powered by solar energy effectively in the world, including India, where they are often used for irrigation and drinking water.
The main advantage of solar pumps is that they work for free. A solar array connected to the pumping mechanism gains all the required power from simple sunshine. This also means that the system independently. There is no need for complicated wiring for the electricity and outside fuel is not needed.
The amount of pollution caused by the use of conventional pump has also completely eliminated. This is a big advantage, especially when used for irrigation on the farms where pollution can possible on site damage. Keeping the fossil fuels from the equation for the pumping of water will reduce potential contamination. In addition, the use of solar energy offers many benefits for agriculture, the farmers, for example, a solar pump used in an area of low-lying, which often flooded or to move the water used to feed animals and plants.
For any system of water pump, both large and small, the installation of solar systems is one of the easiest and most profitable. No long procedures for determining the wiring of the solar panels, and there is no need for extra fuel. Many of these systems, also the digital monitoring and control instruments adding for convenience.
Worldwide, the solar energy is one of the best ways of powering pump instrument. Simple installation, low maintenance, and reducing pollution are just some of the many benefits.
