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.

太阳能系统是解决气候变化和长期能源安全问题的有希望的解决方案，特别是在经历多变天气条件的地区。光伏（PV）能源系统的性能可能会受到挑战，当光伏阵列的各个模块接收不等数量的太阳辐照度。这种情况导致其电气特性的多个局部最大功率点（mpp）不确定。如何确保光伏系统以全局MPP运行，而不是以局部MPP运行，仍然是一个挑战。因此，需要研究如何减少光伏系统在非均匀辐照模式下的能量损失。Solantro Semiconductor Corp.是为分布式和可扩展可再生能源系统中使用的模块集成电子产品开发芯片组和参考设计的领导者。为了提高光伏逆变器**性能，Solantro需要在其DC-DC功率优化器中加入一个先进的控制器，以在全球MPP下运行**。这项大学-产业合作计划旨在开发一种先进的最大**功率点跟踪（MPPT）技术，以找到能够提高光伏逆变器效率的全球最大功率点。预期的结果有可能改善基于新型实时MPPT控制器的先进光伏逆变器的设计和制造。该平台的目标是非常具有成本效益，高可靠性和易于适应各种光伏逆变器。
