Robotic PV cleaning, with service in Italy

SolarCleano, a Luxembourg manufacturer active in more than 50 countries, designs and builds robots for cleaning photovoltaic plants, from industrial rooftops to utility-scale parks. C+P Energy Solutions is its exclusive distributor for Italy: sales, demos on your plant, operator training, spare parts in stock and service in Italian, with direct access to the manufacturer's engineering team.

The range

Chosen by the job, not by the panel

For a service company or a plant owner, the right model depends on the work to be industrialised: rooftops or ground-mounted parks, a few large plants or many small ones, normal or steep tilts.

F1The core model: industrial roofs, logistics warehouses, mid-sized ground plants. Up to 2 MW a day with one operator. M1Compact, fits in any car. Residential, small commercial and industrial, portfolios of distributed plants. L1Extended brushes, tilts above 25°. Ground parks with long rows, up to 2,000 m² per hour. T1Robotic transporter for F1, M1 and L1: moves the robot from row to row on ground parks. B1 and B1AUtility scale, brushes up to 6 metres, up to 8 MW a day. B1A fully autonomous, also at night.

Why clean

Dirt on modules is lost production, not a cosmetic detail

Soiling, the loss of yield caused by dust, sand, pollen, droppings and particulate, can cut annual output by up to 20%, with monthly peaks up to 25% on low-tilt plants or near particulate sources (references: IEC 61724-1 on the Soiling Ratio, NREL, SolarCleano technical documentation). In central and southern Italy, in farming areas and near busy roads, measured losses are often between 5% and 15% a year.

Rain is not enough: at least 20 mm of concentrated rainfall is needed for a noticeable cleaning effect, while light rain redistributes particulate and leaves streaks that worsen hot spots.

Manual cleaning works, but has three growing limits:

Rising hourly cost, between labour, work-at-height equipment and fall protection.
Limited output: an experienced two-person crew usually covers 0.3 to 0.4 MW a day.
Risk of module damage: wrong brushes, uncontrolled pressure and walking on panels are documented causes of microcracks and warranty disputes.

SolarCleano robots work with controlled pressure on the panel, between 3,500 and 4,200 Pa, well below module manufacturers' load limits, with double-bristle helical brushes and control from the ground by remote or autonomously. All models clean dry or with water and can be dismantled for transport by a single operator.

Validation

Tested by independent institutes, approved by module makers

Fraunhofer CSPNo significant change in electrical performance or electromechanical integrity after repeated cleaning cycles on TrinaSolar, JA Solar, Jinko and LONGi modules (Report V235/2025; Report V262/2024 for L1).
Canadian SolarUse of F1 and M1 on CS6W-MS modules without voiding the warranty (Confirmation Letter, 31/07/2024).
JinkoSolarCompatibility with framed modules, warranty terms unchanged (Statement, 13/11/2020).
LONGi SolarStandard warranty confirmed on modules cleaned with F1.
First SolarB1 approved on Series 2, 3, 4 and 6 modules (16/08/2022).
SolargeNo surface or cell damage after extensive testing.
Saudi AramcoPublished study: no microcracks under electroluminescence after 1,000 cleaning cycles.

For plants with performance guarantees (PPAs, O&M contracts with service levels, contractual performance ratio) full documentation is available on request.

Next step

See it working on your plant

The quickest way to know whether a SolarCleano robot fits your operations is a demo on your plant, or a technical meeting on your portfolio. We run demos and site visits throughout Italy, most often in Piedmont, Lombardy, Veneto, Emilia-Romagna and Tuscany.
