From the company-
The questions about cleaning the solar panels and maintenance of the solar/hybrid plant in general, as well as the longevity of the battery power storage, are all part of the process of making this investment, with both juwi and Giza being the selected contractors, both of which have significant experience and technical abilities to build this facility.
The running and ongoing maintenance of the solar plant will be a key component of how Centamin maintain and look after all of their engineering assets. Clearly, there will be a reliance on solar experts to ensure that the power plant will deliver the power it is designed to do, and the regular inspection and cleaning of the panels is of course a part of the above responsibilities.
Regarding the hybrid battery aspect, and from how I understand it, the battery power is a back-up to provide sufficient power for when the plant transfers from solar power to fuel generated power and vice versa - the key to operating a production plant the size of Sukari's facility (12-13m tonnes of ore processed per annum) is maintaining constant power, and the transfer from one source of power to another will need back up should there be any volatility from solar power, whether it be a sudden lack of sunshine (which very occasionally happens in the Sahara Desert, which the Eastern Desert is of course part of), or other potential disruptions.
The battery power unit is 7.5MW, and I am not technically proficient enough to know how this is able to power the plant and for how long, but I am certain that the intention for the solar/hybrid plant is to be effective during sunlight hours whilst fuel will be used for the remainder of the 24 hour periods.
Also remember that solar power in Egypt is not a nascent business.
The Benban solar complex north of Sukari is in fact one of the biggest solar plants on the planet, delivering something close to 1,700 MW of power. This has been operating successfully for over 2 years now and is 45x larger than what is being built at Sukari. There is very good technical knowledge in Egypt, and this is only increasing as more projects like Sukari get commissioned. Though this is from personal knowledge, the advances which have been made in efficiency of renewable energy have been dramatic over the past few years in particular, and I have no doubt that the most proven yet most modern applications will be utilised for the Sukari solar plant.
Hope this information helps.
