Rural electrification through renewable energy in Nepal
Nepal is rich in hydropower. However, due to various constraints the rural sector of Nepal is still deprived of a national electrical grid. Renewable energy resources are the most viable and accessible sources to electrify these rural sectors. Micro-hydro and solar photovoltaics (PV) are widely used renewable energies for rural electrification. Presently, this source provides electricity to only ...

What is the phenomenon that the OPGW optical cable is broken by lightning?
The damage phenomenon of OPGW optical cable after lightning strike is similar to the damage phenomenon of overhead ground wire after lightning strike. At present, it is found that most of the broken strands of OPGW optical cables are outer aluminum alloy stranded wires, and there are also a few cases of broken strands of aluminum-clad steel wires caused by lightning strikes. There are two main ...

For cheaper solar photovoltaic systems
It is known for several decades, photovoltaic devices that exploit the sun's energy to convert into electricity used to provide a sustainable alternative - and potentially unlimited - the use of fossil fuels. So why these solar technologies have they not been adopted more widely? Simply “because they are too expensive," said Ji-Seon Kim, professor of Solid Physics at Imperial College of ...

Wires and cables in winter are prone to quality problems
In the severe winter, when laying and installing wires and cables, many construction workers will find that the wire and cable products of good quality often have some phenomena such as hard wire body, falling off insulation and damage, etc. Many construction workers think it is the wire and cable products themselves. There are quality problems, and cable manufacturers also insist that the ...

Market penetration and pay-back period analysis of a solar photovoltaic system under Indian conditions
The use of pay-back period analysis for economic evaluation of solar photovoltaic (PV) system reinforces the importance of the duration of the system. In a dynamic economic environment, the cost of energy increases at a faster rate than the common inflation rate. A time can be ascertained at which the market entry of the PV system will be profitable, i.e. at which the pay-back time drops below a ...

Thermal management of non–concentrating photovoltaic panels under extreme ambient conditions
Solar photovoltaic modules have reduced efficiency levels when the ambient temperature is very high. In this paper, the temperature and the efficiency of a non–concentrating flat plate collector is determined by a one dimensional steady state analysis at different solar radiation levels for the city of Riyadh, Saudi Arabia where the radiation intensity and ambient temperatures are very high. The ...
