  • Solar PV inverter system

    The only fuel of a solar PV inverter system is the incident irradiance. Of course, there are many local factors that make it difficult to evaluate this local resource accurately without actually measuring it (which is obviously the best thing to do). All solar inverters involve a lot of simplifying assumptions. For example, shading is an important factor, but is usually incorrectly estimated, ...


  • Instruments to measure solar radiation in the field of renewable energy

    In recent years, we have seen a marked increase in the demand for the construction of plants for the production of energy from renewable sources. Many efforts have been undertaken for the production of energy from sunlight, ...

  • Solar Power 2011 - Solar PV Breaks Records in 2010

    By J. Matthew Roney Solar photovoltaic (PV) companies manufactured a record 24,000 megawatts of PV cells worldwide in 2010, more than doubling their 2009 output. Annual PV production has grown nearly 100-fold since 2000, when just 277 megawatts of cells were made.  Newly installed PV also set a record in 2010, as 16,600 megawatts were installed in more than 100 countries.  This brought ...

  • Soluzione Solare presents the solarimeter `Sunmeter` at the 24th EU PV SEC

    In a solar PV system, by measuring solar radiation, we can determine whether, at a given moment, the facility is operating correctly or underperforming. As it yields with “feed in tariff” this check is unquestionably important during the testing phase and also during normal operation, if the facility is of a certain size. “Soluzione Solare” is an Italian company which has developed from a small ...

  • PV Monitoring: Smart Solar Monitoring with Smart Weather Sensors

    A PV installation should earn money. But only if all system components operate without faults, the owner can reap the maximum benefits. That´s why you can only be sure if your system works properly, if you track environmental data in comparison to your actual output, which smart solar monitoring systems offer. Webinar about Increasing Efficiency with ...

  • Webinar Smart PV Monitoring with Smart Weather Sensors

    Udo Kronmüller, our Expert for Solar Monitoring held a webinar about best practise in various uses of smart weather sensors in PV monitoring applications.  He discussed in this webinar how, in addition to solar radiation, other environmental factors such as temperature, wind, precipitation and lightnings also affect the productivity and stability of utilities. The long-term ...

  • Ingeteam exceeds 120 MW of PV power supplied in Chile

    Ingeteam has exceeded120 MW of PV power supplied in Chile. This record figure has been achieved thanks to the good results obtained with the INGECON SUN PowerMax central inverters, featuring a rated power of 1 MW and a maximum efficiency of 99.1%. These inverters have been installed in a solar plant with a 100 MW power output, being the largest plant in operation in Latin America to date. This ...

  • Lufft Compact weather sensor with Secondary Standard to revolutionize PV-Monitoring

    As of now the Compact weather sensor from Lufft WS510-UMB, equipped with a Kipp & Zonen pyranometer of the secondary standards, unites the precision of a variety of meteorological individual sensors in a single all-in-one device for the first time. The sensor is simply installed with only one cable, this means a measurable lower effort of installation and maintenance as well as significantly ...

  • Detecting defects in solar cells

    Solar panels, or photovoltaic (PV) modules, are being rapidly deployed across the world as costs fall and the need for sustainable, low-carbon energy grows. Being able to effectively characterise PV cells is a key factor in quality control during manufacturing and understanding their long-term behaviour. NPL researchers, Simon Hall, Matt Cashmore and John Blackburn, have developed a new technique ...

  • Solar Power Market Opportunities in Australia

    As Australia is moving towards increased solar power generation, the installed capacity of solar modules has shown considerable growth in the recent years. The use of solar energy for power generation had started way back in 1992 in the country with a few pilot projects and an installed capacity of 7.3 MW. With Australia’s power generation dominated by fossil fuels and a lack of clear solar ...


  • Weather Stations Monitor Solar Panel Arrays

    Columbia Weather Systems has added two ISO second-class compliant solar radiation sensors as options for its Weather MicroServer to improve monitoring the efficiency of solar panel arrays. The Kipp and Zonen (top) and Hukseflux thermopile-based sensors can be mounted horizontally for global radiation measurement or at plane of array (POA) for PV solar applications. With high performance and ...

  • China should support solar thermal energy research

    China must support technological research on solar thermal energy, say Huang Ming and Yidong Gong. China is rich in solar energy. More than two thirds of the country receives more than 2,200 hours of sunshine every year. Estimates put the amount of solar radiation landing on China as up to 10,000 times the energy capacity of the Three Gorges Dam. But despite the huge potential of solar power in ...

  • More efficient solar power with space technology

    A new system from an Italian company uses weather satellite data to estimate the potential of solar cell power plants and monitor their performance. The approach helps to give a faster return on investments in clean solar energy. Solar cells have been used for many years to power pocket calculators and, more recently, street signs, garden lighting and other small devices. But since the need ...

  • Europe’s biggest solar power incentive bolsters Ukraine

    Solar-power capacity in Ukraine is forecast to double this year, spurred by the completion of Europe’s biggest photovoltaic plant in December and incentives a third higher than anywhere else in the region.   Developers in the former Soviet republic may add panels with 300 megawatts of capacity after last year installing about 200 megawatts, according to the Association of Alternative ...


  • Getting More Electricity out of Solar Cells

    Original story at MIT News When sunlight shines on today’s solar cells, much of the incoming energy is given off as waste heat rather than electrical current. In a few materials, however, extra energy produces extra electrons — behavior that could significantly increase solar-cell efficiency. An ...
