Parabolic Trough or Solar Tower? A technology decision
Securing cost reductions and carving out routes to grid parity remains as ever the most pressing issue for the CSP industry. At the crux of this pursuit is understanding the associated costs of the CSP technologies themselves, whether it be Parabolic Trough, Solar Tower, Linear Fresnel or Dish Sterling. Delving even deeper, the ability to identify and successfully implement cost reduction ...

Morocco’s Solar Future
Located on the north west of Africa, just across from the narrow Strait of Gibraltar, Morocco’s dry and sandy terrain has made it a leader in solar energy production. As a relatively developed country in its own right, Morocco is electrified and at the start of the 21st century, more than 50% of all electricity was produced by burning fossil fuels. However, the authorities in Morocco ...

Solar Thermal Power Plants
THE BENEFITS OF SOLAR THERMAL POWER PLANTS Solar thermal energy production requires two main things: sunlight and equipment to capture, store and disperse the energy. Only two types of solar thermal systems exist. They are the passive systems, which do not require equipment (such as the heat build-up in your car whenever you park it in the sun), and active systems which require a method to ...
