Photovoltaic emulators (PVE) are power electronic systems able to reproduce the output "CurrentVoltage" characteristics of photovoltaic panels in various operating conditions. They are indispensable for the design and evaluation of the operational components of a photovoltaic energy system, such as battery chargers and Maximum Power Point Tracking (MPPT). Those emulators prevent the experimenta...

A refurbishment project at the University of Northumbria in Newcastle upon Tyne, United Kingdom, provided the opportunity to install one of the largest building-integrated photovoltaic systems in Northern Europe. Photovoltaic panels have been incorporated into w Integrated into conventional rain-screen overcladding w Installed using normal building industry practices w High system reliability H...

Solar energy can be converted directly into electric and thermal energy through photovoltaic cells and thermal collectors, respectively. However this conversion, in particular the photovoltaic, has a reduced efficiency. A solution proposed to increase this efficiency is with the hybrid solar structure, which consists in the junction of the photovoltaic panel and the thermal collector in a singl...

Electric power is a basic need in today’s life. Due to the extensive usage of power, there is a need to look for an alternate clean energy source. Recently many researchers have focused on the solar energy as a reliable alternative power source. Photovoltaic panels are used to collect sun radiation and convert it into electrical energy. Most of the photovoltaic panels are deployed in a fixed po...

Standalone photovoltaic system requires a proper battery charge controller. The main disadvantage of photovoltaic system is its variations in output voltage. Therefore to obtain a stable voltage from solar panels, DCDC converters are used. This paper explains the use of cuk converter with MPPT technique in a photovoltaic system. The MPPT is implemented by incremental conductance algorithm with ...

The Sun provides approximately 100,000 terawatts to the Earth which is about 10000 times more than the present rate of the world's present energy consumption. Photovoltaic cells are being increasingly used to tap into this huge resource and will play a key role in future sustainable energy systems. So far, solid-state junction devices, usually made of silicon, crystalline or amorphous, and prof...

The maximum power point tracking (MPPT) controller in the Photovoltaic system is the key to verify all kinds of MPPT control algorithms. But the development of actual controller has the defects of needing long periods, artificial code writing and so on. RT-LAB real-time simulation platform is an advanced model-based engineering design and test application platform. The outstanding real-time per...

The low conversion efficiency of solar cells produces large amounts of thermal energy to the cells, and with an increase in the temperature of solar cells, their electrical efficiency decreases. Therefore, a hybrid photovoltaic thermal system improves the overall efficiency of the system by adding thermal equipment to the solar cell and removing excessive heat from these cells. In this paper, w...

Module temperature is an important parameter of photovoltaic energy systems since their performance is affected by its variation. Several cooling controllers require a precise estimation of module temperature to reduce excessive heating and power losses. In this work, an adaptive neuro fuzzy inference system technique is developed for temperature estimation of photovoltaic systems. For the lear...
