Proven performance in GCC: reliable energy output and no need for cleaning Installed and operational in GCC since February 2012
Save thermal energy: fuel gas, diesel or even crude oil Cost-competitive renewable energy source vs combustibles
Stabilize cost of energy over 20 years and industrial cost of the products GCC have a highly volatile energy market in terms of prices, significant further increases expected
Minimize dependence from fuel gas and diesel supply, in particular in remote areas Fuel gas and diesel supply in GCC is uncertain in quantity and timing of supply
Avoid consuming oil in crude oil refining in non-normal operations
Viable solar thermal storage up to 200°C allows load coverage up to 24/7
Contribute to corporate social responsibility plan and save on CO2 emissions Apply international standards to industrial processes in terms of emissions
Achieving carbon emission targets for the oil industry with TVP panels:

Siddiqui et al., Solar Energy volume 86, Issue 9, September 2012, Pages 2620–2631
PV panels face a number of challenges when deployed in high ambient temperature environments:• Under perform especially at temperatures over 40ºC • Require frequent, systematic cleaning (dust, sand, pollution)
TVP panels operate at high temperature with high efficiency and minimal cleaning required
TVP – Best Solar for Hot Climates
Suited for hot climate operations (as opposite to PV): higher the ambient T°, higher the efficiency
