Photovoltaics (PV) and solar thermal (ST) collectors are often competing between themselves not only because the investment capacity is limited but also because the energy demand and roof space is limited and both types of panel provide energy which can be converted to a different type of energy under a certain efficiency. Therefore, it makes sense to develop a ratio that quantifies the differe...

This paper investigates ways to obtain consumer preferences for technology products to help designers identify the key attributes that contribute to a product’s market success. A case study of residential photovoltaic panels is performed in the context of the California, USA market within the 2007-2011 time span. First, interviews are conducted with solar panel installers to gain a better under...

Solar energy is one of the most abundant sources of renewable energy for the future. This solar energy can be extracted by PV system. Many methods for PV installation are carried out, such as roof top PV system, dam top PV system; floating PV, canal top PV system etc. In canal top system, PV panels are placed above the water canal which saves installation area and reduces evaporation loss. The ...

The solar photovoltaic (PV) systems are facing serious problems due to unavoidable losses in their system, leads to more devation of output power from the input power level. This effect is known as a mismatch effect and is available in PV systems. Many losses are encountered in PV system and it is difficult to minimize such losses. In this paper, the influence of thermal effect on the solar PV ...

The present study aims at investigating the feasibility of using solar energy as a power source to run electro-kinetic remediation in order to clean-up lead from three types of Iraqi soil. In order to do so, it carries out six tests with enhancement conditions, involving pH control and injection wells. Conducted in the city of Baghdad, Iraq, the experiment, is divided into two groups so that th...

Local electricity generation is one of the key challenges of technology for developing regions. Although we were driven by the need to power rural connectivity solutions, the solar controller described here makes sense for any remote ICT project with power needs up to about 100W, which includes most home solar systems, as well as single PC projects, such as kiosks. The intended use of this boar...

Abstract: NMOS-based Integrated Modular Bypass for Use in Solar systems (NIMBUS) is designed as a replacement for the traditional bypass diode, used in common solar panels. Because of the series connection between the individual solar cells, the power output of a photovoltaic (PV) panel will drop disproportionally under partial shading. Currently, this is solved by dividing the PV panel into su...

We installed solar panels and digital meteorological equipments whose electrical power is supplied using PV on July 13, 2011. Then, the relationship between the electric power generation and the irradiation, air temperature, and wind velocity was investigated on a roof at a university. The electrical power generation, irradiation, air temperature, and wind velocity were monitored over two years...

In this work we describe a systematic approach to power subsystem capacity planning for solar energy harvesting embedded systems, such that uninterrupted, long-term (i.e., multiple years) operation at a predefined performance level may be achieved. We propose a power subsystem capacity planning algorithm based on a modified astronomical model to approximate the harvestable energy and compute th...

The global increase in energy demand and exponential exhaustion of fossil recourses has favored the development of new systems of electricity production. Photovoltaic solar energy is undoubtedly one that has the highest application in housings, due to its simplicity and easy implementation. In this work, a new prototype of photovoltaic solar tracker with Arduino platform was developed. Feedback...
