> requiring a large budget to constantly clean them
It's not unfathomable that a cheap, automated method of doing this could be developed.

And that cheap, automated method will require energy as well. Perhaps a bigger concern maybe that such a method may require a cheap fluid to prevent damage to the panel coatings and that might be water, already a scarce resource in those places.
> Each of the 400,000 installed panels required one litre of water to clean. A 15 days cleaning cycle required 124 million litres of water (enough to sustain 9000 people) while rain in the Cholistan desert is rare and far between. Providing such huge amount of water in desert terrain, became a challenging and daunting task for management team. Besides, the manual cleaning methods allowed setting of dust before it was re-cleaned.
