In this study, thermodynamic and economic analysis of a photovoltaic electricity generation system (PVEGS) with and without self-cleaning panels is reported. In the first part, thermodynamic analyses are used to characterize the performance of the system. In the second part, the economic comparison of photovoltaic electricity generation with and without self-cleaning panels is carried out for a...
the increase of cell temperature with increased irradiance is probably the mostsignificant disadvantage of using photovoltaic modules equipped with booster reflectors. the aimof this study is to investigate the possibility of improving the performance of a photovoltaic waterpumping system by using a booster reflector and to keep the temperature of pv panels at a lowlevel by cooling pv panels wi...
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...
A proposal for energy management in an off-grid photovoltaic pumping and irrigation system is presented and evaluated for a specific case study. The system is assumed to be based on off-the-shelf components (photovoltaic panels, battery banks, DC/AC converters, relays, submergible pumps, etc.), with a microcontroller-based energy management system, deciding when to disconnect the load from the ...
Accumulation of dust from the outdoor environment on the panels of solar photovoltaic (PV) system is natural. There were studies that showed that the accumulated dust can reduce the performance of solar panels, but the results were not clearly quantified. The objective of this research was to study the effects of dust accumulation on the performance of solar PV panels. Experiments were conducte...
Electricity generation purposes renewable energy brings a important role especially Photovoltaic (PV) panels that can be covered our basic energy (electricity) needs. This photovoltaic panels cover a domestic level (solar power for home), commercially (solar power for commercial applications) or at the community level. Here used this photovoltaic panel as an input of PV-transformer-less inverte...
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...
One of the key challenges of employing photovoltaic systems is to extract maximum power of the panels. This problem is known as maximum power point tracking (MPPT) technique. The MPPT stands for establishing situation in which output power of the panels reaches its maximum allowable power. In this context, this paper is to assess the technical requirements to achieve maximum output power of a n...
Climatic conditions affect the performance of photovoltaic panels. In this study, the effect of ambient air temperature and relative humidity on the performance parameters of two types of silicon photovoltaic solar panels, including mono-crystalline silicon (mc-Si) and polycrystalline silicon (pc-Si), were studied in the laboratory scale. The experiments were carried out by the performance test...
The promotion of domestic grid-connected photovoltaic electricity production through social learning
Background: An effective social learning process which enhances public understanding of photovoltaic installations in residential dwellings and the economic instruments used by governments to encourage investment in this form of energy is regarded as an important component of implementing renewable energy policy in Australia. Methods: The development of social learning was explored in deliberat...
