“…Variety studies have confirmed these hypotheses. Zsiborács et al [36] and Chandrasekar et al [37] have shown that in crystalline solar modules, a 1 • C temperature increase will generally result in a 0.5% reduction efficiency. According to Skoplaki [18], the efficiency the crystalline modules can have a loss of 0.3% to 0.5% when the temperature increases by 1 • C. Krauter [19] establishes that the energy-temperature relationship varies between 0.4% and 0.5%/ • C for the same technology.…”

Access to electricity and supplying reliable energy are the key elements that support local economic development and contribute to reducing poverty. Moreover, the problem of environmental protection can be considered as a factor of sustainable development. In response to these many challenges, appropriate national and regional policies, as well as mechanisms, have been implemented. In Mali, strong dependence on the importation of oil, growth in demand, and the low rate of electrification have pushed the highest authorities to think of diversified technological solutions like renewable energy for the satisfaction of energy demands, especially photovoltaics, for which the country has significant potential. The hybrid systems used is a compromise, because the emission rate of carbon dioxide emitted by thermal power plants must be reduced and limited to preserve supernatural disasters. For this, hybrid photovoltaic systems coupled to the grid increased, but the management of the production of these photovoltaics poses a lot of problem due to its intermittent status. It is in this context that we conducted an optimization study of a hybrid system photovoltaic connected to the grid. We applied our approach to the most extensive distribution post of Mali capital. For the simulation, we used the modeling and simulation tool named HOMER.

“…The main benefit of the photovoltaic systems used for joining solar energy is the insufficient low cost of maintenance, greenhouse gas emission and few limitations concerning the absence of mechanical noise coming from moving parts and site of installation. Although, photovoltaic systems suffer from comparatively low conversion effectiveness [5]. Therefore, increasing power tracking of the solar system is important and proved to be significant in a PV system.…”

A photovoltaic system is installed, since 5 years in a medium size house in Amman city, Jordan to support the electrical system of the house. The system consents from 14 boards, converter, and two-way electrical meter. Each board is producing 240 watts/hour as a maximum, and the total watts produces from the system is 3.5 kW/h, this is in an ideal situation, when the sun is perpendicular to the system. The total kW produced from the system in 4 years is approximately 24,000, with an average of 6,000 kW/annual; and 500 kw/month, which is equal to 50% of the total house consumption. With respect to cost, it reduces the monthly bills to 1/6 of the monthly cost in summer, and 1/3 of the monthly cost in winter. The total cost of the system at installation time, 4 years ago, is $6,000, and accordingly the system rewards, its cost in 5 years. The cost of the system now is one-third of the previous cost; and the government is encouraging householder to support their homes by photovoltaic system by giving them one-third of the cost as cash money. Jordanian banks are now accepting monthly payment of the system without additional cost. This system does not only reduce the electrical load from the main electrical board, but also reduces the government oil bill, as Jordan is a poor country with respect to oil and other resources, but is also helping to reduce the pollution caused by burning conventional oil.

“…This rise in T PVmodule diminishes the η El of the PV module as well as reduces the life of the module. For every 1°C increase in temperature, the η El of the PV module falls by 0.4% to 0.65% . Different active and passive cooling techniques can be used to decrease this elevating temperature to boost the PV module's η El .…”

Performance enhancement of photovoltaic modules by nanofluid cooling: A comprehensive review

2020

View full text Add to dashboard Cite

Summary Only 15‐20% of solar radiation incident on the photovoltaic (PV) cells is utilized which further reduces due to the rise in the temperature of the PV module and it also degrades the lifespan of the PV module. Therefore, numerous attempts were made to reduce this rising temperature of the PV module and different cooling techniques were employed. Nanofluid cooling is one of the potential cooling techniques for lowering the temperature of the PV module and augmenting the heat transfer by increasing the thermal conductivity of the nanofluid relative to the base fluid (BF). The experimental and numerical studies related to the cooling of PV cells with nanofluids have been reviewed. It was found that the heat transfer from the back of the PV module is enhanced with the augmentation in the concentration of nanoparticle in BF; however, some studies also demonstrate that the enhancement in the heat transfer also depends upon other factors such as the geometry at the rear of the PV module, nanoparticle material, nanoparticle size, BF, ambient conditions, etc. This review article also demonstrates the various issues with nanofluids such as instability, technological difficulties, high system costs, and the impossibility of finding a viable operational design which creates a barrier in the commercialization of the nanofluid cooling technique for PV modules.
