  • 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, ...


  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...
