Reverse-osmosis water
We control cleaning and rinsing water quality to reduce the risk of mineral deposits.

Start with your asset
Choose what needs care. We design the intervention.
Start with the facility you need to care for. Each service explains the benefit, process and information needed to assess the project.
01
Photovoltaic plants
Recover the light blocked by soiling with reverse-osmosis water, zoned coverage and an O&M-focused plan.
02
Industrial facilities
Clean roofs, warehouses, skylights and structures while coordinating every phase with production, logistics and access.
03
Facades and glazing
Protect the building’s appearance without starting with a more complex access solution than necessary.
04
Technical inspection
Identify signs, organise the evidence and decide which areas need closer review.

More than 20%: the potential cost of letting soiling build up.
This figure was observed in a Málaga case study during prolonged accumulation and is not a forecast for every plant. Dust, pollen, sand and other deposits reduce the light reaching the module; actual impact must be checked against site data.

- Less foot traffic on roofs and rows
- Coverage planned by zone
- Less auxiliary equipment where feasible
- Cleaning and documentation in one project
Protective coating
After cleaning, we can apply a treatment compatible with the module, technical requirements and warranty conditions.
Specific cleaning product
When soiling requires it, we define the product, local test, rinsing and runoff management in advance.
Operational advantages
Less setup. Less height. More control of the work.
The drone is not the goal; it is the tool. We use it where it can simplify access, structure the intervention and reduce disruption around the asset.
Access to complex areas
We assess facades, roofs and facilities where access shapes maintenance.
Less exposure at height
Where feasible, part of the work can be carried out from the ground.
Less auxiliary equipment
The intervention may require less setup and occupy less space around the asset.
Documented service
Visual records, inspection and a maintenance recommendation can be integrated into the scope.
Industrial cleaning
The facility gets cleaned. The operation keeps moving.
We assess roofs, skylights, warehouses, facades, canopies and elevated structures. Work is organised by zone and operating window to reduce interference with production, logistics, access and internal circulation.
- Less exposure at height where feasible
- Lower occupation and access setup
- Phased execution
- Local test and final record
How we work
First we understand. Then we intervene.
A good intervention starts before take-off. We study the asset, access and constraints to define a realistic scope, reduce surprises and choose the right method.
View detailsSetup + operation
A good intervention starts before take-off
We prepare the equipment, check the water supply and coordinate the work zone before starting. The final method follows an assessment of the surface, surroundings and site activity.
Understand
We review location, material, height, geometry, soiling, access and the service objective.
Validate
We check surface compatibility, surroundings, available resources and operational feasibility.
Define
We select the method, configuration and, where needed, a localised test before closing the scope.
Plan
We agree the perimeter, access, schedule, protection and coordination with site activity.
Intervene
We execute the work and adapt the operation to the actual conditions of the day.
Document
We deliver the agreed record and recommend a maintenance interval where it adds value.
Adapted method
The method adapts to the surface. Not the other way around.
Configuration, water, distance and procedure are adjusted after reviewing the material and surroundings. The aim is to act with care, protect the surface and coordinate with asset activity.
- Configuration adapted to the work
- Local test where appropriate
- Visual record as agreed
Adapted to your activity
The service changes because every asset operates differently
01
Property managers and communities
A clear assessment, coordination with the building and recurring maintenance options.
02Hotels, offices and retail
Work windows and controlled zones designed to reduce interference with users and activity.
03Industry and logistics
Technical planning compatible with access, production and site-specific restrictions.
04Photovoltaics and O&M
Cleaning, inspection and records integrated into an asset-care programme.
05B2B partners
Specialist capacity, multi-asset coordination and white-label delivery where required.
How we can help
From a one-off need to planned maintenance
01
One-off project
Assessment, scope and proposal for a specific need.
02Mandarina Plan
Annual, six-monthly, quarterly or asset-specific maintenance schedule.
03Solar Care
Cleaning, records, inspection and thermography where the scope requires it.
04Mandarina Partners
Coordinated B2B or white-label service for one or several locations.
01What advantages can a drone provide?
Where feasible, it can reduce work at height, auxiliary access equipment, preparation time and occupation of the surroundings. The actual benefit depends on the asset.
02Can you work on any surface?
No. We review material, condition, geometry, dirt and surroundings before confirming the method and configuration.
03Do you need permits or to stop activity?
It depends on location, airspace, work zone and type of operation. We assess and coordinate this to minimise disruption.
04How is the quote calculated?
We assess area, height, geometry, dirt, material, access, location, available resources, restrictions and frequency.
Next step
Show us the challenge. We’ll tell you whether a drone fits.
Send a few photographs, the location and a short explanation. We will review access, constraints and scope, then explain whether the service is feasible and what comes next.
