SolarCleano B1 and B1A, utility-scale robotic cleaning

The largest robot SolarCleano builds. It straddles the row and travels its whole length, covering its width in a single pass.

• Brushesconfigurable up to 6 metres wide
• Cleaning capacityup to 8 MW a day in standard configuration
• Adaptationautomatically follows structure height and tilt and keeps the set pressure on the modules constant
• Operationdry and wet cleaning, remote control, batteries with up to 8 hours' runtime

Same frame and capacity as the B1, with on-board artificial intelligence: the robot runs cleaning sessions on its own, at night too, under remote monitoring.

• Session scheduling via the SolarCleano web app.
• Monitoring by the maintenance team via mobile app.
• Automatic adaptation to the structure's height, tilt and geometry.
• Scheduled night cleaning, which according to the manufacturer triples capacity compared with traditional solutions and sharply reduces staff cost on large parks.

The B1 is approved by First Solar on Series 2, 3, 4 (non-ARC) and 6 (ARC and non-ARC) modules, with a compatibility letter dated 16/08/2022. For other manufacturers' modules compatibility is checked case by case during technical analysis.

On a 50 MW park with a PPA, every percentage point of soiling recovered is measurable extra production. B1 and B1A are not assessed as a substitute for labour but as a tool that feeds directly into the owner's return. Optimal cleaning frequency, expected return and integration with the O&M plan are calculated on site, from measured or estimated soiling, the energy sale price and the service contract in place.

In Italy, B1 and B1A projects are run in direct partnership between SolarCleano and C+P Energy Solutions:

1. First contact and qualification with C+P Energy Solutions.
2. Joint technical analysis of the site: topography, tilt, structure geometry, access, operating constraints, module specifications.
3. Project proposal by SolarCleano, with brush and robot configuration sized for the site.
4. Commissioning and training on the plant with SolarCleano's R&D team.
5. Ongoing support in Italian from C+P Energy Solutions, with direct access to the engineering team in Luxembourg.

The segment is aimed at independent producers and owners with portfolios above 50 MW, infrastructure funds with strict performance guarantees, corporate PPA developers, EPCs designing robotic cleaning into the plant from the start, and structured O&M operators considering robotic cleaning as a standard across the portfolio.
