Residential photovoltaic (PV) systems in the US are often compensated at the customer’s underlying retail electricity rate through net metering. Given the uncertainty in future retail rates and the inherent links between rates and the economics of behind-the-meter PV, there is growing interest in understanding how potential changes in rates may impact the value of bill savings from PV. In this ...

The development of renewable energies particularly energy from wind, water, solar power and biomass is a central aim of the European Commission's energy policy. There are several reasons for this choice: renewable energies are sustainable, nonpolluting, widely available and clean. Increasing the share of renewable energy in the energy balance enhances sustainability. It also helps to improve th...

Compared to a photovoltaic array, photovoltaic/thermal concentrator module can produce thermal power for various productions in downstream cycles addition electrical energy. In this study, the system combined production of electricity, heat and cooling based on has been evaluated. triple system, lithium bromide-water absorption chiller with capacity 5 kW was used. organic Rankine generation cyc...

Automation means Delegation of human control to machine. A PLC (Programmable Logic Controller) is a device that was invented to replace the necessary sequential relay circuits for machine control. A SCADA (Supervisory Control & Data Acquisition System) is used to control the process where person cannot go or stay for longer period. The aim of tis paper is to provide information about hoelectric...

As an important part of s mart grid, microgrid(MG) is a new form of s mart grid in the future. Microgrid(MG) technology can effectively integrate the advantages of new energy and renewable energy generation and provide a novel way for large-scale applicat ions of new energy and renewable energy connecting to grid. This paper deals with the problem of economic operation of microsources in the mi...

Photovoltaic solar cells have been extensively used for various applications and are considered one of the most efficient green energy sources. However, their 2D surface area harvesting has limitations, there is an increasing need to explore possibility multiple layer harvest enhanced density. To address this, we developed spectral-selective transparent thin films based on porphyrin iron oxide ...

In this paper, a performance study was conducted to investigate single and dual-axis PV systems to generate electricity in five different sites in Kuwait. Relevant data were obtained by using two sources for validation purposes. A commercial software, PVsyst, was used to analyse the data, such as metrological data and other input parameters, and compute the performance parameters such as capaci...
