“…In this contribution, a measurement campaign of the atmospheric attenuation based on the analysis of the VIS and IR spectra is presented. The measurement concept was previously described in 2 . The new measurement strategy is based on the measurement of VIS and IR spectra of the sun radiation reflected by a white diffuser screen at two suitable locations of the plant.…”

Solar radiation attenuation in the path from the heliostats to the receiver is one of the main contributions to production estimation uncertainty in the operation of central-receiver concentrated solar plants (CSP). Few systems are commercially available to monitor this phenomenon and those available have high uncertainties due to the non-uniform attenuation pattern across the wavelength range of the useful solar radiation. In this work, we report the results from a 6-month measurement campaign carried out in a commercial CSP tower plant using a prototype system to measure the spectrally-resolved solar radiation attenuation. The system measures the differential spectrum between two pairs of high-resolution spectrometers (VIS and IR) separated approximately 800 meters and each coupled to a telescope system. Both systems are pointed at a white Lambertian target and regularly take a baseline measurement pointing at a black target to eliminate contributions from the diffuse light present in the solar field. The system is calibrated to <1% uncertainty using the reference of a portable spectrometer at both locations. Full-spectrum measurements were taken every 5 minutes. Spectral characteristics of different atmospheric conditions (suspended dust, fog, humidity) and their intra-day and seasonal evolutions are observed and analyzed.

“…The construction of solar photovoltaic may be adaptable in the form of ground-mounted, rooftop, building integrated, and roofjack mounting. On the other hand, the performance of solar photovoltaic depends mainly on conversion efficiency determined by the factor of material, construction and spectrum [12]. For optimal energy conversion, some strategies are further taken into practice that may include providing heat exchanger, or using an active cooling to avoid temperature increase that may reduce the efficiency [13].…”

The demand of electricity that keeps increasing necessitates additional electricity generation. The highly dependence of power generation on fossil fuels implies the intensive use of this resources that may cause them finish sooner than predicted. On the other hand, the use of fossil fuels for transportation is quite dominant. The development and use of electric transportation system is a solution for reducing fuel consumption. However, the electricity for supplying the electric transportation system is mainly from the generation system that uses fossil fuels. For further improvement, the energy supplied to the transportation system should come from the renewable energy generation. This may lead to minimum use of fossil fuels besides giving minimum effect on environment. This paper presents the development of renewable energy generation where the generated power is used to supply the storage that charges the electric bicycle. The power is generated by solar photovoltaic panels and it is saved in a battery. The charging for the bicycle is taken from the battery. The developed system is off-grid since the system may be placed in the non-electrified area. This prototype will be a role model regarding the combination of renewable energy generation and green transportation system.
