George Monbiot's attack on solar energy and the government's "cash-back" solar photovoltaic (PV) market-building scheme paints a distorted picture of the industry I work in, and government policy towards it (Are we really going to let ourselves be duped into this solar panel rip-off?, 2 March).First, Monbiot gets the workability of solar wrong. He says: "The amount of power PV panels produce at this latitude is risible, [and] they also produce it at the wrong time." Those who buy panels, therefore, will own a mere "fashion accessory". The companies who manufacture solar PV in the UK have shown that putting solar panels on all available building surfaces would generate more electricity in a year, under typical cloudy British skies, than the entire electricity consumption of our energy-profligate nation. Some fashion accessory.Of course, just a fraction of that area of buildings would suffice because we would want to mix and match renewable technologies - large and small, onshore and offshore - so matching loads and compensating for the fact that solar generates by day and not by night.Second, Monbiot says the government's scheme targets money where economies of scale are "impossible" - an incorrect assumption because solar electricity costs will inevitably

Yingli Green Energy Holding Company Limited has announced that it has entered into a sales agreement to provide green energy to SunDurance Energy for much of the next year.Under the agreement, the New Jersey-based SunDurance will receive more than 10 megawatts of photovoltaic solar energy modules over the first three quarters of 2010.Liansheng Miao, Chairman and Chief Executive Officer of Yingli Green Energy, said the partnership would be an avenue that would allow Yingli to continue its expansion into the U.S. solar energy markets."Our growth strategy in the U.S. is focused heavily on the commercial and utility-scale markets, where we are pleased to have several projects already underway with SunDurance Energy and other large-scale developers. As today's announcement signifies, we're dedicated to not only building our customers' loyalty and trust through our reliable products, but also through our ongoing superior customer support," added Robert Petrina, the managing director of Yingli Green Energy Americas.Al Buknam, the CEO of SunDurance Energy, added that the latest agreement was the largest photovoltaic module purchase agreement in the company's history and was just the latest of numerous agreements between the two companies."We purposefully set this agreement on a fast- track timeframe given our positive outlook

China will step up efforts to promote the development of its wind power industry so as to make full use of its wind resources, said Zhang Guobao, director of the National Energy Administration, yesterday.China's installed wind power capacity is only 22 million kilowatt, far less than its wind energy resources of about 2.6 billion kW on a theoretical basis.The Chinese government will support several large wind power equipment manufacturers so that they would be able to compete with their overseas rivals, added Zhang.The government also plans to accelerate the development of nuclear power. Last year, the government approved the construction of six nuclear reactors and will approve a few more nuclear projects this year, said Zhang.At the end of last year, China's nuclear power capacity stood at 9.08 million kW, with 23.05 million kW of capacity under construction.

Incentive pays for 30 percent of home photovoltaic projects Xcel Energy announced Monday the launch of incentives for Minnesota electricity customers to install solar panels on top of their homes and businesses.The Minneapolis-based utility's Solar*Rewards program, designed to encourage solar energy growth in the state, includes a one-time payment of $2.25 per installed watt of generating capacity to help offset the cost of customers installing small or medium roof-top photovoltaic systems.For a 3.5 kilowatt residential installation, or 3,500 watts, a customer would receive an incentive payment of $7,875, or about 30 percent of the project's cost. In addition to the Solar*Reward incentive, federal, state and local government agencies could provide customers with other rebate opportunities.To qualify, Solar*Reward participants must agree to install a system with a capacity of between 0.5 kilowatts to 40 kilowatts. In exchange for the incentive payment, ownership of the renewable energy credits, or RECs, produced by the system will transfer to Xcel Energy for a term of 20 years. Xcel Energy will also buy any energy that a system produces in excess of the customer's needs.Xcel Energy's Solar*Rewards plans support the installation of about 2 megawatts of solar energy each year for the next three years,

More than 5,000 MECASOLAR trackers installed in the Grupo OPDE photovoltaic solar farms in Spain have endured with great strength over the weekend of 26 and 27 February, the winds that swept the Iberian Peninsula from north to south caused by the explosive cyclogenesis and which reached speeds of up to 200 km / h accompanied by heavy rains. This was the case of the large solar farm at Almaraz (Cáceres)-with 2-axis MECASOLAR solar trackers, which withstood hurricane winds up to 132 km / h without any of the trackers registering any incidents. The explosive ciclogenensis also particularly affected the solar farms of Belvis de Monroy (Cáceres), which recorded maximum wind speeds up to 102 km / h.More than 5,000 MECASOLAR trackers installed by OPDE are located on solar farms in Andalusia, Extremadura, Castilla-Leon and Navarre. All of which withstood the hurricane wind speeds caused by Xinthia, without registering any structural problems and or panel breakage. "Last weekend our trackers have once again beat records for wind resistance of 132 km / h showing the market on the ground that they are the most robust and best built mechanically on the market," says Gustavo Carrero, Director

Although concentred solar power (CSP) generation is probably better known, solar thermal (ST) collectors employ a much lower level of technology and convert far more of the sun's energy into useful heat, according to a new market analysis.The report "Solar Thermal Power Report" by ReportBuyer describes solar thermal energy technology in its various applications, describing the various technologies: collectors, receivers, heat storage systems and energy conversion units.CSP uses lenses and mirrors to directly tranfers solar energy into electricity via conventional steam and heat turbines or by focusing light onto photovoltaics. The Ivanpah project being developed by BrightSource in California is a high-profile example.Solar thermal (ST) collectors--used for water heating and building heating (or cooling through solar chillers)--have more capacity and produce more energy than wind power and more than geothermal, solar PV and ocean energy combined. By 2009 there were 147,000 megawatts (MW) of wind power, 174,000 MW of solar thermal collectors. By comparison there was only about 1,000 MW of CSP and about 17,000 MW of solar PV capacity.The last two or three years have seen strides forward in all solar technologies and many 50 to 100 MW CSP power generation projects are being developed, with larger ones in

The three new inverters in the SolarMax TS series have rated capacities of 50, 80 and 100 kilowatts and work in the MPP range of 430 to 800 Volts. The devices are highly compact and are better protected against dirt than their predecessor models in the SolarMax C series. In addition, Sputnik\'s developers have succeeded in boosting the European efficiency from 94.8 to 95.5 percent and to increase the acceptable ambient temperature range by five degrees. A processor monitors the IGBT switch on the power component which improves operating safety and reliability. Sputnik has replaced the electrolytic capacitors with film capacitors which has extended the useful life of the inverters by several years. DC and AC circuit breakers are now accessible from outside. This means that electricians can separate the inverter safely from the grid before they open it. Several devices can now be switched off simultaneously using one external switch. The new inverters communicate via RS 485 and Ethernet. The graphic display can be operated using three keys. Pilot project in the Wankdorf Stadium The TS series meets all the specifications contained in the new Medium-Voltage Guideline published by Germany \'s Federal Association of Energy and Water Utilities (BDEW)-
