The year 2014 witnessed the breaking of the historic 25.0% power conversion efficiency record for crystalline silicon solar cells, which was set by the University of New South Wales (UNSW), Australia, in 1999.1,2 Almost simultaneously, Panasonic, Japan,3 and SunPower, USA,4 reported independently certified efficiencies of 25.6% and 25.0%, respectively, both using industrially-sized silicon wafers (see Fig. 1 and Table 1).
[pdf] Most solar installations require an electrical and/or building permit. Determine if your utility requires an interconnection agreement to connect your solar system to their grid. Contact them early in the process. Decide between a DIY or professional install.
[pdf] Greece’s National Energy and Climate Plan (NECP) outlines ambitious targets for continued solar capacity growth, aiming for 18.5 GW by 2030 and 26.5 GW by 2035. This rapid expansion of solar energy is crucial to Greece’s overarching goal of transitioning to 100% renewable energy sources by 2030.
