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 ...

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 ...

Plan B 4.0 by the numbers - data highlights on solar energy
Concerns about global warming, rising fossil fuel prices, and oil insecurity have prompted calls for a new energy economy, one that replaces fossil fuels with renewables. The sun is an enormous reservoir of energy; in fact, the sunlight reaching Earth in just one hour is enough to power the global economy for a whole year. Harnessing some of this energy is an essential component of Earth Policy ...

Full-energy-chain greenhouse-gas emissions: a comparison between nuclear power, hydropower, solar power and wind power
Fair comparison of the climate impacts from different energy sources can be made only by accounting for the emissions of all relevant greenhouse gases (GHGs) from the full energy chain (FENCH) of the energy sources. FENCH-GHG emission factors of most of the non-fossil fuel energies are lower than those of the fossil fuels that are in the range of 500-1200 g CO2/kW h(e). The improvement rates ...
