Solar systems are promising solutions for addressing climate change and long-term energy security issues,**especially in areas experiencing variable weather conditions. The performance of photovoltaic (PV) energy**systems can be challenged when individual modules of a PV array receive unequal amounts of solar irradiance.**Such conditions lead to uncertain multiple local maximum power points (MPPs) on their electrical**characteristics. It remains a challenge of global optimization to ensure that PV systems operate at their global**MPP rather than at local ones. Therefore, research is needed to reduce energy losses of PV systems under**non-uniform irradiation patterns.**Solantro Semiconductor Corp. is a leader in developing chipsets and reference designs for module-integrated**electronics used in distributed and scalable renewable power systems. In order to increase the PV inverter**performance, Solantro needs to incorporate an advanced controller into its DC-DC power optimizers to operate**at the global MPP. This collaborative university-industry proposal aims to develop an advanced Maximum**Power Point tracking (MPPT) technique to find the global MPP that will increase PV inverters efficiency. The**expected results have the potential to improve the design and manufacturing of advanced PV inverters based on**a new real-time MPPT controller. The platform is targeted to be very cost-effective, highly reliable and readily**adaptable to a variety of PV inverters.
