According to the latest test results show, National Semiconductor Corporation (National Semiconductor, abbreviated NS) launched a new power management technology for solar PV panels because of local or short-time compensation is shadowing fell generating capacity, so as to System restore up to 57% loss of generating capacity.

NS has 50 years of research experience in power management technology, and use this technology, successfully developed SolarMagic power optimizer.

Even shadows or other problems make the system power efficiency severely affected, SolarMagic power optimizer can still improve solar cell panel power generation system. NS facility in Santa Clara, California within the wind controller PV system performance test, the test uses a barrier to simulate an obstacle blocking the roof, which produces just the shadow of a shadow circuit design using traditional solar installations. Although the day only 8-16% of the area of ​​solar panels is shadowing, but the average drop of generating capacity from 35 to 40%.

Another tested solar power generation apparatus using the same test conditions, the only difference is the addition of the NS SolarMagic power optimizer, the results showed an average increase in generating capacity than previous systems 30-37%. In other words, SolarMagic power optimizer can save 57% of energy loss.

NS renewable energy products noted Ralf Muenster, director, expects SolarMagic power optimizer can bring to market innovative products for the solar energy.

Has been installed on the roof of solar photovoltaic systems will encounter shadows and solar panels for sale mismatch between the transmission and other issues, and this new technology for the global commercial and household use to provide a viable solution. Previously considered unsuitable roof mounted solar power systems, is now available to overcome the problem and successfully installed to help the U.S. achieve an early and established by President Obama renewable energy targets.

NS developed SolarMagic technology is designed to enhance the solar power generation system. Since solar modules is limited by its own characteristics, so whenever it encounters the real environmental problems, such as trees, chimneys, parapets or leaves shadowing, the system's generating capacity will be dropped. Specifically, the system is only 10% or less of the solar cell plate board surface is shadowing, generating capacity will be dropped as much as 50%, significantly affect home users ROI.
