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 ...

Renewable energy technologies in Nepal
Nepal, one of the least-developed countries, has a per capita energy consumption of about 336 kilograms of oil equivalent (kgoe), which is much below the world average of 1,474 kgoe. Around 85.27% of the total energy consumption comes from traditional energy resources and only 0.48% from renewable sources. About 40% of the total population has access to electricity. This 40% uses 33% from the ...

Revolutionary Education: PV Powered
Travel around rural Latin America and you’re sure to see schools without basic educational tools, let alone electricity. Not in Cuba. More than 34,000 children in rural areas of this small Caribbean island are reading, writing, and watching educational videos using the power of the sun. Cuba’s commitment to education is astounding. Although many countries have obligatory schooling, Cubans take ...

The UK lags behind EU counterparts to achieve 20% renewable energy target
While some countries have almost hit their targets the UK still has a long way to achieve its 15% renewable energy target by 2020. The EU is more than halfway to reaching its 20% target of generating energy from renewables by 2020, according to new figures published today by Eurostat. The EU's 2009 directive on renewable energy set individual targets for all 27 member states, with a goal for the ...
