Abstract

In solar energy, there are innovative ways to improve the efficiency of photovoltaic cells. The most common improvement in solar energy is concentrated photovoltaics. One way to implement concentrated photovoltaics on a commercially available module is the use of reflectors, as a low concentrating photovoltaic module. In this study, an improvised low concentrating photovoltaic module was designed and fabricated. The effects on the current and voltage harmonic distortion of the output of the implemented concentrating photovoltaic module was evaluated and compared to a plain module of the same kind. This was done to normalize the possible effect of the concentration on the power quality attributes of a 50W polycrystalline silicon module The load used was a 22W magnetic ballast, a non-linear load that triggers harmonic distortion to integrate the common load scheme in power grids. The study comprised of collecting the harmonic distortion of the load simultaneously with the irradiance and panel surface temperature. Moreover, the study compared the harmonic distortions of the plain and implemented concentrating photovoltaic module. Results showed that during lower levels of irradiance, the implemented concentrating photovoltaic module had a lower total current harmonic distortion than the plain module. The implementation affected the total voltage harmonic distortion and not the current harmonic distortion in this study, specifically to the rating of the panel, inverter and load.
