💧 Waterless or wet cleaning for utility-scale solar plants? The answer depends on the site.
There is no single cleaning method that works best everywhere.
Our latest SolarCleano case study looks at how climate, soiling type, cleaning frequency and water availability should influence the choice between dry and wet cleaning.
One result stands out:
On a 100 MW ground-mounted solar plant, two SolarCleano B1A units operating autonomously on a weekly, waterless cleaning cycle helped restore inverter performance from around 70% on average to 99–100% across the site.
But waterless cleaning is not always the answer. 💧
The key takeaway: the right cleaning strategy should be adapted to local conditions, not based on a universal rule.
Choosing between dry, wet or hybrid cleaning means looking at the complete picture: performance, water consumption, operating frequency and long-term OPEX.
