“…In areas of frequent rainfall, it was demonstrated that the rain could clean the PV modules to an extent of restoring the performance to within 1 % of full power (Hammond et al, 1997). Accordingly, in a more recent soiling analysis performed in Crete, with climatic conditions almost identical to Cyprus, the annual soiling loss was 5.86 %, with the winter losses being 4 -5 % and 6 -7 % in the summer (Kymakis et al, 2009). A soiling investigation was carried out also for the systems installed in Egypt and specifically by comparing the energy produced by a clean module, a module that has been exposed to dust for a period of one year and a module that has been exposed to dust but cleaned every two months.…”

“…The power loss due to soiling is therefore a function of the type of dust, the length of time since the last rainfall and the cleaning schedule (Kymakis et al, 2009). In warm climates such as the one in Cyprus, soiling losses increase as the periods between successive rainfalls increase and this is more noticeable during the summer period.…”

“…This means a reduction on the power efficiency of the solar cells system. Recently, Kymakis et al [8] attributed the solar cells power loss of 4-5% during the winter and 6-7% in summer to the type of dust deposited, the time lasts after the rainfall and the cleaning schedule. Moreover the experimental study conducted by Hassan et al [9] indicated that the degradation of the solar cell performance decreased rapidly during the first 30 days of exposure.…”

The accumulation of dust on the solar cells panels worsens the situation and lowers the efficiency of the solar cells day by day especially in the regions known by their high rate of dust, low frequency and intensity of rain. The accumulated dust on the solar cells panel blocks the cells from the sun's rays and act as a screening effect as shown by the calculated spectral transmittance of dust which decreases the performance of the solar cells over time until the cell panels are cleaned manually or by rain. The tilt angle of the solar cell panels affects considerably the amount of accumulated dust on the surface of the panels.The study focuses on the effects of dust accumulation on photovoltaic solar panels in Jazan region. The effect is tested in outdoor measurements and it was found that regular dust accumulation reduces the solar cells efficiency by about 10% for an exposure time of 16 weeks. Moreover the tilted panel with an angle of 30° receives more dust than the panel tilted by 50° which means higher efficiency loss for the lower tilted panel. The efficiency loss is significant of large of annual monetary losses. This study can be considered as a reference to predict the level of degradation of any photovoltaic system that might be installed in the Jazan region and also to estimate the real cost include the cost of the solar panel cleaning.

Abstract. This paper presents new integration techniques to combine silicon-and dye sensitized solar cells (DSSCs).The idea of this work is to install DSSCs on the back side of silicon solar cell panels to make use of the reflected radiation from the ground or from solar cells arranged behind.It has been shown that the architecture of the combined solar cells can be designed as monolithic structure by depositing the DSSC layers one after the other on the back side of Si-cells or as hybrid structure by combining Si-cells with foil-DSSCs. To enhance the current efficiency the different kinds of cells were connected in parallel. The TiO 2 nano particles, dissolved in dispersion, were coated on foil-or glass substrates. Here, it was possible to enhance the efficiency of dye sensitized solar cells by treating the semiconducting layer with pulsed UV radiation. As a result of the UV light treatment the short circuit current has more than tripled. Nevertheless, the cells maintain their low-cost characteristics, because synthetic dyes have not been used to coloured the nano particles. Additionally, the DSSCs were connected in series. Thus, it was possible to adapt the voltage of the DSSC to the voltage of the Si-cells.
